December 25 - 1923 Tuesday A fine bright and cool morning, and Drtn Dunbar calls for me on the Tnd to take me to the depot. Checking my trip up to Washington, had breakfast at the depot, and 8 A.M. I am off New York City. Set due at 9.45 and at 10:30 at the Pennsylvania Station. At 10:10 I am off for Washington where I should arrive at 3:20 this afternoon. Put up at the Park Hotel corner of Pennsylvania and Eighteenth st. This is to over by the White House. Then hurried up to the Reith's to have Christmas dinner. They had four other guests: one a young man studying to be a priest. Mrn Reith telephoned around to have the Oerrills, and Easton call but they had their own guests and could not come. Mr and Mrs Marins Campbell called. It was a very enjoyable evening. At 11 P.M. called back to hotel.

December 26-1923 Wednesday Started out at 9 A.M. To see the new struc- tures about the White House again, and then gwent to see the Freer Art Gallery. At 11 A.M. got into the National Museum and at 11:45-saw Stanton, Min Moody and Dorothie Omerill. The letters history of D.A. Geology is now printing by the Gude Press. Omerill is 70 years old, but looks to me almost as young as when I saw a party his departure in the N.M. 20 years ago. At 2 P.M. went to the large Intern. Aep. building to attend the Council Meeting of the G.S.A. At 6 P.M., adjourned to 8 P.M. The latter meeting started until 11 P.M. Main topic The Lawson Abstract Journal. Council hearty in favor of the more, and willing that the Society take up its publication of the funds we raised by the Mat. Geol.

Thursday. Stose's paper 'New Type of Appalachian structure' had nothing whatever to do with the Polysric movement that he had on the more known Triassic faulting. Vang-Lan's Addren will appear better in print since he put out all the detail. When our study the larval methods of distribution. Especially in connection with Goodring's paper.

December 27, 1903, Thursday. Spent the day at the meeting of the C. S. A. in the Astoria Building. Payton's Presidential Address on Criteria of Congric Conclution appeared to me to set up a lot of "sham creel" to have the fun of knocking them down. He is going it strong on showing that the Legalian of Congric Percentage of the living is erroneous. Dana stated this once than to success, and beside Payton often uses them in his own oral conclution. White's Presidential Address on Isostasy printed much later, the results of which come to show as well as can be that the crust is in isotatic balance. Borries paper on the old and new triangulation of California made a plain case that this state is undojing a tricol of "sham creels." There is with local horizontal movement, a general movement from the south to the north. Cushman and I had a long talk on the value of trams in underground conclution.

The first thing to do in any area is to have a standard of correlation - a well made type section determined. Forams carefully identified make for safe age determination. This can be done not only in a general way but even down to some cases to foot. The species must be well known and cut of the outside into as well the inside. He had what looked like one species other broken down layer by layer revealed not less than 6 species. For oil workers it is not essential that they know the literature or the names of the forms, only that the species are definitely known and then always referred to by some gontrol. Correlations of forams are usually more valuable than single species in correlations. Forams are very sensitive to ecological conditions. Pelagic forms come in with

"Open sea or current conditions, Temperature of the water is of greatest value and the forms follow cold or cold water conditions into the depths. Rarely in areas of warm temperature these are found in the shallow water while the cool temperature one in the deeper cold waters. Of Bd Agjuria there are 14 species and when those are known are also found in emulations. Cushman was the first to point out that the Micre has derived Cutacens forms. They are water worms and show that they are washed out of olden state as forms and entered into Mircers state, When forams are all closely identified it can be found that these animals are not or try saying as in Debel -- and especially by Payton. All in all Forams are of great value in late Mesozoic and Cenozoic conditions. Cushman told me that Ostracods are

common in dinosarrips and that among them are many highly ornate forms. They must also have decided local evoloution drivers. The average size of fregues is about 1/2 millimeter and among the ornate form four gr abone one millimetre. Every change in ectopic conditions bring on a different fregam assemblage. On Tom started and explained to me his mine grass work in the late Cret..-Tnt Dinim problem. The upshot of it all is that the Late, the Lawni counts of the Tnt Dinim can be traced laterally into the Lawn part of the Camontale. The only marked break and we as more significance is between the Tnt Dinimi and Drosatch.

Washington, D.C. Dec 28 Friday Listened all day to papers before the B.S.A. The first one was by Laworn telling what the Research Council is doing, followed by a full account about the proposed Abstract Journal. Followed it by a resolution on- dorsing the project and appealing to those that dare to make the project possible. It was adop- ted by the Society. I then gave a paper showing that the Fox Hills lies into the Lance, this into the Lobo of the Fort Union and that the Lance and Lobo join eastward into the Cannon Ball marine. There- fore all these things are Cretaceous, and the true Mesozoic-Cenozoic boundary lies between the Fort Union and Basalt. In the afternoon I presented an abstract of Williams' paper on the geology of the Franklin Mts. Parks objected to Williams' conclusion about the arc system as ex- plained by him. Strome thinks there is no proof for Beltian deposits.

"The paper on the Belgian series of [illegible] showed that there are too many formations and that some join into one another going northward. He [illegible] drops out more and more. However a young man came and spoke of the [illegible] in the Belt. Not to the effect that a final correlation is not yet at hand. The Bemquet at Ramrokers Restaurant and was led by the Pocketed Hammer Club and was a great success. Kemps was toast-master, and an improved officiation was given to Professor Dr. H. Rice and curiously one to Wrey. Last year at Ann Arbor one gave [illegible] for a large cup. Woodring's paper had truly on the migration of Antillian mollusca into the Mediterranean. Held that there was a stral area across the Atlantic during all of Cenozoic time, and once to the close of the Pleistocene."

Readingtn, Dec 29 1923. Saturday Spent the morning at the National Museum picking out the starfish in the Spring collection that should be sent to Spencer in England. All the unidentified material should be sent to him and if this is not possible then those I listed which I gave to Mr Moody. Then had to lunch Whittaker and Bell. The afternoon was devoted to a Council Meeting of the C.S.A. The ticket for next year is taken Pres, Scott of Princeton, Brock for First Vice Pres, Campbell for Second Vice Pres, and W.O. Grant and Mrs Bartram as Councillors. Next meeting at Ithaca. I then moved to the home of the Reiths but had dinner with the Oerrills. From Merrill I learned that [illegible] was the original man against me last year and that Bauslin was the active agent. Of course Hollick did the corresponding with them.

Quirk's paper of yesterday was to the effect that much of the north shore Lake Huron grinds and precises are metamorphosed sediments. Read this paper when printed. Larson spoke well of the paper, and Keith saw his rocks and slides. He told me that Quirk is correct. Miss Jonas' paper on Pre-Cambrian was a very similar sequence to that of Franklin Furace, some Paleogic relations to Pre- Cambian with areas. Guest on the Tampico Area paper. Has here about 3000 feet of shales and marls almost devoid of large forams. The upper 1000' has an abun- dance of pelagic forams, while the lower 2000 has benthic forms. The upper series is of the Cret (about Cretinichale) and is called the Reloso. It has 700 forms of forams. The lower series in the well known Papagayos formation. Hand cores are put down to 50 feet and or the forams are collected.

Bachington, Dec 30-1923 Sunday. Stopping with the Keiths, and then came in among the first homes of Bachington, they built here when all about was a waste area. Talked George and Geologist all day until midnight. In the afternoon went to the Union Station and purchased a ticket on B.& O. to Cin- cinnati, where I will arrive Tuesday morning at 8 o'clock. Dorothy's paper on the Silurian map to the effect that all of the L.I., Ind. Penn., and central N.Y. is 1 Clinton time, time in Alex- andria. Had a fine series of sections model with detail. Especially valuable in the detail about the appearance of the red beds from west to east.

Washington, D.C. Dec 31 1923 Monday. Had a cab take me to dep't to check my baggage, and then up the Interior Building to see Keith's office. He is at work on a geography of Maine. The big job due is the physiographic map, as that one was we made before. The map is about finished. Spend the rest of the day in the U.S.G.S. library reading The Pan American Soil. I suppose I will have to subscribe to it. Miss LePeres translation of Lierres paper is accredited to me. Looked up this journal mainly to read Dumble on the value of forms in sub surface correlation. Spent out all I wanted. At 4:35 P.M. jam off for Cincinnati.

Cincinnati, O., Jan 1-1924 Tuesday. Arrived at home late (8.35) because the depot is too small to get the train in and out on time. Albert and his daughter was there to meet me, and in that car to take me to 3937 Raymond Ave., Norwood, O. Passed through Elm Park on the way grand when I did my first collecting of birds. At 12.30 we were at Emmas and for a family reunion and dinner. Talked, laughed, listened to Victrola and Radio. Jean made little out of the latter since my hearing is too bad to get a connected whole. Emmas radio resides in paint and the atmospheric noise are enough to make difficulty for me. It is the first day of winter at this moment is down to 24° At 10.30 we were back again to Albert's home and soon we are all retired.

Cincinnati Jan 2, 1924 Wednesday. Wrote letters in the morning (Erans-Lemere) and at 12:30 met Phil and Albert at the Breweil Hotel on Seventh St where we had lunch. Then looked about town and J P M called for Phil at the Schultz Bowling Co. Then in his car to his home when I stopped over night. Had my initiation to radio. Did not like it because of much static mine and other stations. Cincinnati Jan 3, 1924 Thursday. At 9 A M Phil and I in the forms car got to the Daley, then visited the West End Bolley and had lunch with Phil and Al at the Dorell Hotel. Then to Al's home at Homrod At 7:15 Al's daughter takes me in her car to the depot and at 8 P M I am off for New Orleans. On the Day to New Orleans

On the way to New Orleans January 4 - 1924, Friday At about 7 A.M., we are at Chattanooga near the Tenn. Ala. line. It is very cloudy and the land is covered with a white frost. The nam of glistudy has a thin crating of ice. At 10.15 we are at Birmingham, Ala with a flood of bright sun-light. Frost is also here but less decided. It is some old south that I saw for the first time nearly 30 years ago. The villages have no beauty and are composed of a lot of poor renters built in streets or open beneath. The fronts are all of gray timber and the farms in the main of corn with some cotton fields. It is a poor county. Chattanooga I did not see, but Birmingham is a good industrial center having back of it the Clinton arm and the tracks and directors of the Pennsylvania. At noon we are at Tuscaloosa, Ala., a tow

rolling country with a hied red soil in which are abundant some light sand petter or concretions, these are the Cut. hard sands. At Akron, Ala low fan-palms come in showing that those plants may be expected on the edge of climates with cirtuos. Here they are up to 3 feet tall, but the leaves are as full green as in southern Florida. For miles to the northeast of Meridian we pass through what appears True hard Cenopecs, dark- hue clays, one of which are almost black. Arrive at Meridian at 2.30 P.M. The county is low low rolling and more flat. We arrive at New Orleans on time.

New Orleans, Jan. 5, 1924, Saturday. A dark and windy cold day. It is cheer-less to me. Visited the State Museum in Jackson Square; best in bird and mam-mals. Botany is about a failure. Museum no credit to the state, in an old building not intended for museum. Had lunch at Jansen's, speaking Creole eating. As Creole means good I thought I was going to get something fine, but it was very passable. All in all New Orleans has no charms for me. A quaint place once a long time ago, or at least poorly kept up. When will the 'South' ever pick up and bring itself abreast of the times. Many streets have gardens down the center, but the trolley lines have taken possession I may say of them. Even trees have no attention, not even trees in palaces in most cases. The ones in World Famous Quartet are all smutty and most of them uninteresting and dirty.

Houston, Texas Jan. 6-1934. Sunday. Left New Orleans at 9.15 on the Southern Pacific and got to Houston at at 8.05 thirty minutes late. Stopping at The Rice Hotel, apart me, and the room with toilet hot water bath ($14) costs $3.42 per day. But all expensive. Dining rooms at all prices from Coffee Room and Cafeteria to Ladies Dining Room. A little ice stands on the water this morning and the day is cold for this region, The paper says that yesterday was the coldest day in 20 years.

Houston, Jan 7-1924. Monday. Called on R.F. Baker in the Texas Co. working a little seep mine A.M., and came with him and Mess Kniker until 8 P.M. Had a most instructive day looking into the value of framne[illegible] in subsurface correlations. They are very successful in spotting horizons with them and this will lead to an unex- pected stratigraphy connected with the salt domes. These are rising domes ever since Jackson time and appear to be still rising. The Jackson and Clippence strata pitch out against these red lands - islands and headlands in the sea. The Frann, as usually common and well preserved. Most of them show no wear due to washing them only tho mud.

Houston, Jan 8 1924 Tuesday. Called on Heussen and his lady (Mrs Lane), for an order, and put in the morning with them. Then had lunch at the University Club with about a dozen of the Houston geologists. Baker gave the lunch. Present Rumple, Heussen, Pratt, Applein and his wife (Win Richards), Mrs Hnila, Mrs Ellisor, and several others. Then to the Southern Pacific R.R. Building to see the Pal. Lab. of Dr. C.A. Seumble. Saw the Butler geologist Van der Gracht turned up. He is now connected with the Trail and Co., and is of course much interested in Cush-man. In the evening then was a gathering of the clan at Baker's home.

Houston, Jun 9, 1924 Wednesday. Called on Mr Pratt in the morning and soon he explained to me the Goose Creek oil field - a sinking field now fairly submerged by the Gulf waters. A few years ago a part of this area stood about 1 1/2 feet above the sea and is now sunk 1 1/2 feet beneath the sea. There are faults in two places on either side. The land now sunk belongs to the State of Texas and since it is full of oil is very valuable if the sinking is due to the taking out of oil and gas the Humble Co has ownership. I think the sinking is due to the oil extracting, and because it could be shown on seostatic grounds. Then called on Mrs Ellison and talked from until noon. Oliver gave me a dinner party at the Houston Club with Pratt, Baker, Kinder Smith and Humble men. Then called on Miss Appolin [married 3 months] and talked from the rest of the afternoon.

Houston, Jan 10-1924, Thursday. Called on Baker in the morning. Leta had lunch with me at the Rice Hotel. Read and draft about part of the afternoon. Visited the Bakers in the evening at 171 Drew St. At times the air this morning was full of snow, but none lay on the ground. Houston, Jan 11-1924. Friday, Baker brought me the first mail from Om Le Vere on the trip. Write letters to J. M. Clarke, De Solga, Phil, and Le Vere. The Appins and Mr. Baker had lunch with me at the Rice Hotel. The Pratt trip is off. He has data that cannot be side-tracked.

At 5.30 the Batlers take my luggage and me to the Southern Pacific R.R. He had dinner opposite the depot, and at 10.40 P.M. I came off in Tucson. It is the Sunset Route or the Sunset Limited. En route to Tucson, Saturday January 12-1924. It was about 8 A.M. when we passed through San Antonio. Set out at 7:30 in a bright hot and cool morning. All in a sage brush plain with here and there a conspicuous residual chill that look like mountains. The homes are the smallest and poorest with hundreds of cattle here and there. No water is sight but wind pumping wells are to be seen in places. Or it goes for miles upon mile until near Del Rio when the usual rattle of the train clamps and we go over a bridge, over a small stream, a tributary of the Rio Grande - it looks With water there is an abundance of humanity and a town

Del Rio. Occasionally we sees a cotton patch but here the dried and dead bushes are hardly fit for tattle. Out side of cattle raising the chances of creating a living is impossible. East of Del Rio the Comanchian is well explored along the banks of the Rio Grande and Devils River. The strata lie in almost directional hills, but gradually become undulating with dips up to five degrees, and locally up to ten degrees. All in white chalky muddy limestone. On the plain above the river are occasional residual hills to foot or light. We cross the Pecos River over a high steel bridge 321 feet above the river. It is an intrenched river in the Comanchian, the lower 200 feet of which is heavy bedded chalky limestone and the rest then bedded sand stone. The river itself is narrow and dry dirty yellow. The walls of the limestone many vertical in the heavy bedded limestone, old and dark grey in bright places covered by the calm white her and then merely fallen grass. [illegible]

"[illegible]" is a rapidly incised [illegible] ridge. The plain above is decidedly undulating in thin Comanche bedded material. The landscape is that of a semi-arid country, open sage brush and cacti. No trees anywhere, and every-where mother earth sticks out, but work in everywhere due to cloud bursts. The ridges are nearly naked of vegetation as the draws are somewhat filled with loose material. West of the Pecos River the Comanche is the same as before, and the strata appear to lie nearly horizontal. This is true in the canyon, but in the Saliney cutting one sees considerable undulation, even sharp but slip folding and some faulting. Long before one gets to Vanderorn in west Texas one are rising up a stream valley and the escarpments go higher. At Vanderorn we are 2772 feet above tide and the hills rise about 350 feet higher. The strata are all horizontal and I should say Cutaceno = Comanchean. We are constantly rising in altitude.

and the escarpments are getting still higher. From Sanderson Tr Emerson there is fine table-land scenery and all are about horizontal. From the white escarpment water the mesas cascades and at Sanderson it is tapped on the hillside and tanked. Evidently the slope of the strata is south or southeastward. As we proceed west I see (Damborne?) goes interbedded in light green shales. The dips here are but slightly off the horizontal. If roads seem due west a field they must be for them, since all is one rock exposure. To the east and west of Tesmes are fine exposures. Here the outcrops rise up to 1000 feet above the Railway. In places the conglomerate shale rises with dips of about 10 degrees. Damborne predominates here, though I can appear to me shale also. All appears to me conformable series, and as one's want get

To the north after miles the [illegible] igneous (drawn out) are steep and vertical while further north is the eroding Permian ceries, only slits dips. It is one of the first exposures known to me of an angular unconformity. As I get further afield it appears to me that the central cratered chote is the centre for that appeared distal uplift after the proliferation of the older series. The Paleogric Series rise from the central nucleus and Old Paleogric crest, the rest on this central nucleus and to descend to the eastward as I saw earlier and noted above. I don't if any of these mts are much higher after the Palaeops than 1000 ft. and yet they are shrouded in cords that make me the mts all melt away as the bear away from them. They made out the high sun light a peculiar illumination. At mile last 96 east of Marathon some rocks to the south of the track appear to stand over-

Ploja was over at the station to meet me. He took to the Old Pueblo Club where I have taken a room. As we could not get break- fast later until 8, A.M. we went to the Santa Rita Hotel and had a good breakfast. This is the best hotel in the town, and as I can get a room for 50 dollars per month may con- clude to stay here. Then walked out to the University of Arizona about 1/2 miles from the station. It is a good looking small knut, well adorned with native or introduced sub tropical plants. All irrigated.

"Then had lunch at Stroganov's home and met his wife. She does not look like a Russian. Her folks originally came from Holland and settled in Russia 200 years ago. After lunch took one in his car to the San Xavier mission, nine miles out of Tucson. The out scenery about Tucson is striking, and all of the lower land is a cactus covered Holson plain. The out is the main one of lava flows, breccias and ash tuffs rather than Miocene case than older. There is also an Archeozoic granite, another of Post Carboniferous age that has metum all round the earth, and a third one of primary late Cretaceous age. formations, but the older granites are schists (Pinal). The Pinal schist is the basement of Arizona and is of the same general age as the Vishnu of the Grand Canyon. It is curly granites and divides."

Tucson, Jan 14 - 1924 Monday. Spent the morning at the Univ. of Arizona with Roworne, Dean Butler, and Stogams. To morn I am to look up rooms to live in. Over the State Redbird, Dr. Lausen and his assistant Wilson. Also over the petrolo- gist Guild, born in New Hampshire. And motuatin agrees. This one of the best lips of the morning. Spent the afternoon reading. To my surprise Dean Butler put up a dinner party for me at the club. He had President Murray, the Manager of the State Cliff Co, two of the U.S. Mines Dep who have a station here and Prof. Roworne. There were 11 of us to dinner.

Tucson, Jan. 15-1924, Tuesday. Last night made an engagement with Dean Butler to meet him at 10 A.M. Waited on him in my office to find out that he just then are. At about 11:30 detour car to Ashmore Douglas home to see if could get a room there. Had a room that I liked, but Mrs Douglas (teaches Spanish) would not rent for less than $5 months. As far as I chose to get into a furnisher near the University, and then made an arrangement to take room 230 in the Santa Rita hotel. Moved in in the same afternoon and unpacked all my luggage. Then wrote to Severn and Emma. The room is to cost $50 per month, otherwise 2 1/2 Sunday.

Tucson, Jan. 16-1924. Wednesday. Entire morning on the Foram paper. In the afternoon walked out to the Univ., and at 4 P.M. we are off in a Univ. car 1/5 miles N.-W. on the Lilron Bell Road, and then through (=Pichaer delg Calayia) a gap about 2 tr 3 miles W. to a mountain farmy at the base Purial schist (= Archeozoic), on which lies a third series of Cambrian quartzite. Then follows 100 tr 200 ft. of thin and thick bedded limestone with some sandy li. and apparently some shale joints between the li. Some of these li. are done like lithographic stone but most of it more a less granular. These granular layers are replete with communal trilites, small Lingulellas, and Acrotreta. I would not be surprised if a fauna of 50 species exists here, but it will take much pounding to get identifiable specimens. Much of the tillite payments are the thick part like the spines of the free cheeks and the doubt- lure portions. But still no, free cheeks and tails are not rare. There is also apparently much

room tunnels. Some of the smooth surfaced slabs show current washings. The quartzites Ravensmo thinks may be some other age than the limestones. While I did not see the actual contact between the two series, yet I was within 3 feet of actual contact, and get this is not the slightest evidence to separate the two series (Later, I do not think this is Ravensmo's idea). The fauna of the limestones looks to me very much like the Llans Cambrian that formed up in Walcott about 30 years ago. It is therefore all Upper Cambrian or Ordovician, and more probably the same sequence down a few years ago in the Grand Canyon—the Tonto series (Tapeats m., Bright Angel Shale, Muav Li.). The Cambrian appears to end with reddish granular limestones, that also abound in trilobite fragments. Then follows either a thin quartzite or this green is in thick redded magnesians.

limestone. I soon had a large piece of li with a cup tetradral and crystalline spfs that may have been Eridiphyllum. Iron Out better, the student with us, picked up a good but small Alveola reti cularis miserabilis, and later one for also the revolution Al reticularis, and Spirifera Whitrogi. This then made it clear that we have here 2 to 30 feet of thick redded apgresian limestone of Upper Devonian age. Ian followed a vertical scale of thin limestone that I suspect in the Madion limestone. All that are far of fresh come two small tetracralles that were Aren- pbyllum; they had no Chumella. After of comes the Pennsylvanian with Spirifera cameronatus. Unfortunately the time was too short to investigate the li above the Devonian. All the shata stand vertical, and all are folded at one time, presumably towards the close of the Paleozoic or the Cretaceous.

Tucson, Jan 17-1924, Thursday Worked all day on the forum paper, but a little time Le Vere out Sundays. Jan. 18-1924. Friday. Worked all morning on the Forum paper. In the afternoon walked out to the limit, and called on Rausme and Strzanne. Then wrote letters to Le Vere, David White, Gilly, and Baker. Jan. 19-1924. Saturday. After breakfast spent 1 1/2 hours south Tucson, in the vicinity of the Catholic Mission on South Light St. All about here the streets are graded through a fair lot of Caliche. Gathered several samples to show the nature. Here the caliche is essentially all an earthy, erroneous limestone deposited

irregular horizontal layers. On vertical sections one sees a general vertical stria- tion of the rock due to the cracked vertical canals, the layer of which are from 2/8 to 3/8 inch in diameter. It is probably down these canals that the oratu from the surface goes, while through the granular caliche passes up through capillarity the ground oratu. In places the rock takes on a bedded nature with smooth layers some of which take on the vertical fine striation seen in stalac- mite. If the oratu descends through a mass of loose material or rock ticecia or clay, the whole is loosely cemented together. Caliche is easily distinguished from marine limestone by its irregular cavernous nature, vertical canals and horizontal layers of smooth caly li. These smooth layers are more widely spread horizontally, often a few inches and have a few feet in thickness from japan to about four inches. Sometimes the caliche is broken up into ticecia and recemented.

In the afternoon Stizenwe took me at mt 13 miles D. B. of Tucum to Ogden's base to the south of the Cajo Road. The place is an at and med quarry for limestone turned to lime. The series is Ripon Penn- sylvanian, and something like 200-300 ft of thick bedded dark-hue limestone, are seen. The fossils are all pseudomorphs crusted out on the surface. While these surfaces now show or lateritic soil they must have formerly been joint surfaces along which the water could dissolve and carry the solids to silica. The place has been visited now by many students so that all the good things had been taken away. A small Semionula and Papyr uths are the common forms. Several species of Productus occur, and they are the real guides to the horizon. In the life here a large cardinal Euomphalus is

common, and beds 2 to 3 feet thick are made up of Ferestellids still standing as they grew. In places Archaeoidium spines are common. Saw no Fusulinas, but some ovals, all ovate, are exceedingly rare. Also saw Steffonia. Probably there is considerable fauna here, but my chance to see them is as pseudomorphs. This design must be in the Permian, forming the Streebyan. I was much interested in the breaking of these limestones due to the intense heat of summer they joint in a frightful manner and into these joints the water penetrates and creates v-shaped channels. See the various samples taken. The whole surface also is pitted and filled with solution cavities as in pluvial climates. This could not occur elsewhere since the surfacce is very slight. Some of the joint surfaces are also covered with lime deposit (caliche). The whole mass is breaking up into angular sharp pyra- mids that comes crack down the tabular slopes, disintegrating until finally they are worked out onto the beach.

On the lower slopes of the limestone one sees caliche deposit, or that in the vicinity of limestone caliche is formed on the tabular slopes and terms quite close to the limestone out. craps. Later I saw such even on lava slopes. I should think the way the limestone is cracked with solution cracks in all directions, that such in an ancient de- posit might take recognizably as such and find therefore crack such deposits as desert caliches. Probably as they form the tabulars they loose this character. We then are at 4-105 miles farther East on the AFR road near to the western side of the Tucson Mts and in traveling the out to see the Comanchein deposits. The shales appear to be in the main dirty sandstone or sandy shale of a brownish color on the surface. Here occurs an agatized tree about 30"

in diameter and 15 to 20 fut is upheaved. Toll tuff prior fit. Near this log are laminated and brecciated limestones in their beds. A sharp peak also sticks out here and to my surprise it proved to be a quartzite. Of all these things first sample. The tree looked to me like those of the Potomac about Boazhington. He looked for marine fossils but saw none or any leaves or wood debris. Some jasper beds are in greenish shales. The Conemelian must be very thick since we saw it across the hills for more than one mile. The strata is about N-S, and the dip to the E, about 25 to 35 degrees. All the cuts head down due to insola- tion, and the pieces are carried down the grade of the Bethesda, now seeming smaller. The rains wash away the gre debris into the Bottoms, and get for me also sees large pieces. This is due to the cloud bursts and the sheet washing.

Jan 20 -1924, Tuesday, Sunday. Wrote letters to Berkey, Lawson and LeRoy about Geological Abstracts. I then began work on small Historical Sett. At 2 P.M. had dinner at Stroganows home.

As I crawled over the slopes I saw that all the large boulders are surrounded to rounded though they had not gone one than several hundred feet. The smaller pieces are more or less angular. A little below the surface all the agglutinate is cemented together by the faulty caliche, or that this material makes as good on the sides of lava hills as on the mesa. Here the lime must be deposited by the rain crusts and not for subsurface rising crusts. The upper grey-lava is weathering often breaks up into thin sheets up to 3/4 inch thick, and he looks like reddened sedimentary. It heals horizontally across the lava [illegible] straight features.

January 24 -1924, Thursday. This is to be a great day. Lawson and Wilson of the State Bureau of Mines are to take me to the Wetstone Mts., about 50 miles south east of Tucson, or about 10 miles S.E. of Benson. At 8.45 A.M. we start from the Santa Rita Hotel in town ours. In one wagon-End-Lawson and I go, and the upulation End has Wilson, Parsons, Strz- man, and a young Belle of the Canadian Lairrey who is here because of his or her health. Hardy married de discovers that a wife has been unloaded in him threatened with consumption. We go via the Beotle road south park, but main part of Tucson, the road situated between the Southern Railway and the El Paso-South western over the dry side Wilson situated between the western Tucson Mts. and Cerile Hills, the northern Santa Catalina, and the eastern Rincon Mts. The Wilson is fairly flat but rises towards the East. Much

Nearly cryptogen immediately beneath the surface. Caliche is supposed to exist, and certainly from the origin arid it looks this away. When one get tr Dial, 21 miles O.E. the road goes through a series of sort of bad lands topography but with the hills more rounded. These are made up of slightly deformed, rather late Pliocene nearly Pleistocene continental deposits that are distinctly bedded, giving the first impression that the climate was more demid than ours. These are unfortunately relating to my recent continental deposits. After going through these dips for about 8 miles we come out upon a Precambrian granite of any wider extent. This large crystal pink granite, heals up readily into an arkose of low and rounded hills.

Here the ground is light red in color due to the pink feldspars of the granite. Where the granite is actually at the surface it now that it grinds freely and heals up granularly. In places the ground has sand, cream quartz out of pegmatite veins. In other places sand but rarely the granite takes in a dry orecell or- stellation and here heals up more freely. We go further 15 to 20 miles on this granite floor to a considerable ranch house and post office known as Redstone and here go through a fence and south to the north side of the Redstone Dike. The vegetation on this granite floor is markedly different. Wee buccaas and mescal along with red bunches that grows like green, coarse grass, and ragulation grass is in evidence. It's cattle country. Hydran

We can think something like 700

"but this Cambrian quartzite, when it gradually passes over into light colored greenist of Wales, that weathers pillarish. On the sandstone surfaces occur large fucriod casts and round brown holes but these are not Solithus. These holes also occur in the Lignitine (see the two overall specimens). These scales are some hundreds of feet thick (?300 to 400). Then comes in a thick series of thin and thich redded earths and pure limistone with zones of sand at mix. There are also arenaceous limestone, they are separated by shale goes but how well developed I did not make out in the northward slope. All of the limestones carry comminuted trilo- bites and usually in the greater profusion. We found one fine fossil - some near the base, near the middle, and at the Top. Ransom took out a lot of good trilobits. He after so to 100 feet of limestone are pillarish in color.

Hystolites. All of the trilobites and the brachiopods are clearly of Upper Cambrian fauna more like those of the Llano's country of Texas than of the Oriskany of the Ohio valleys. If you get well turn over that both Upper Cambrian and Ordovician are present. Here in the Hystolites beds could be gotten a fine shell collection, and in the end at least 50 species. Near the base of the Shales glauconite is common in the sandstone group. See for Sharply underlying the pinkish Upper Cambrian limestones, occur dark blue Ordovician li. in thick beds. These are marked by an abundance of discretely articulated Phymatodes (small heads) Cla- dosporas (stems 1/2 inch thick), Atrypa reticularis, and other things that may be hygrograms or small Cladosporas. Clearly these are Ordovician in age. Orthus appear commonly beds of Atrypa minorusi-

A perfect hipster or sand horizon concretions, crystallal matter, and flat teeth of chalks. Some are horizons that are not, but Ransom says these can be had by heating the wall as he may form silicified. Later he got silicified ore in Feb 15-1926. The Permophrenia is dry thick, but if any pathy late and later too much tiny or more, and at lower levels Beyond lay the Conachian series with the same general structure and dips. Dale measured about 16,000 feet for but evidently the series replaced itself so that the true thickness may be about 5,000 feet. Allen told me he saw many 'oyster like shells'. Can there be Brachiopods?

The Cambrian sea came in as a sand flat of my Dallas water, and it so continued into the shales and the limestones. In the latter occurred goss of intraformational crysmmerates, the pellets were flat up to 1/2 not thick and in length up to 3 inches. All the edges were rounded. Also several goss in which the pellets are well rounded and Haeckel (see the two specimens) and at first these may be hollow rolled pellets like those of Sargassum. I mistook them for algae, then the sedim ments and especially the crysmmerates along with the communal nature of the holo- lites goss to prove that these sea bottoms were often churned up and rolled into the Haeckel pellet and intraformational crysmmets. These waters were hardly over 100 fath in depth. We are here dealing as well also in the second Canyon region with Dallas near shore flat sea bottoms. The land every where appears to lie to the east and north. The southern and western shores must lie far away.

January 25-26, Friday-Saturday worked on the hist. soil. Jan. 27-1924, Sunday. Trudled all morning on the rock. Had to dinner Mr and Mrs Stroganow and Prof. Ramsey. Saw the latter took are to the base of the Santa Catalina Mts corthern just north of the University. Bring on it over the Tucson Mts one rises to a certain level and then the plane goes down to the Billitz Creek. The stream bed is 200-300 ft wide, but now there is not a drop of water in it. From one rives out of it and then the gravel-triddle-sand washade is everywhere much dissected and much rugged by the finer display of the feet sub-harr cactus. The rocks are here all ancient gneiss, granite and schists from the Mts. There is no @alicke

"Here yesterday on the Pilon just out of Tucson I saw the same kinds of rocks of in much smaller pieces. To me it is clear that originally there was our Rillito Creek and that the Bahada descended regularly to Tucson and in this way the grains of the Santa Catalina the grit to north Tucson. The climate must then have been drier with no influence into the Santa Cruz, and perhaps then was then our Santa Cruz River. Re- cently the climate has become warmer and the streams are now see are cutting through the Pilon, gulching the Bahada, and slipping the north side of the Pilon into the Rillito Creek. Working along these drifts I think some interesting physigraphy could be developed here. The Santa Catalina rocks are all of Pre Cambrian granites, gneisses and schists that farther north are intruded by younger granites - the Post Carboniferous granite,"

Jan 28-1934 Monday, Tucson. Worked all day in the Hist. Sect. In the afternoon walked out to the north- ortheast portion of Tucson among the adobe houses of the Mexicans and Indians. The place once I finally saw the best caliche cut is near the place visited Jan 19. This cut on a street corner gives plainly having a green stone that the large vertical cuts are due to des- cending waters since here the soil is slightly reddish and it erats some of these tubs. I will go back to this place and put a sample pit since it is the best I have seen. I did get a piece on Jan 31 and the red clay soil in the large tubes shows clearly. I noticed also that Blake is correct in saying that the caliche is may always capped by a dense layer. It is here from 15 to 18 more thick. On that the reddish soils

Jan. 29 - 1924, Tuesday, Oracle. Itzanner in a Ford called for me at 8:30 A.M., and are are off for the day to see the Cambrian on the north east side of the Santa Catalina Mts. We go north on the Florence road to Walnut Tree Ranch, 2 miles north of Tucson, and then east to Oracle (37 miles N.E. of Tucson) and east of Oracle pretty 7 miles farther. Here are out a foot of "Pepin-Dance Cambrian. Have the Jepun Cambrian is a series of quartzite ming in thick beds, many of which are clean and white quartzite. All are more or less de- cidedly cross bedded. Finally turning the tip the final 200 - 300 ft. are coarse and fine grained muddy somewhat gray, dirty gelb mit n reddish quartzite that have strangely trilobites. What I saw suggests rather Daulia but Itzanner calls them Archaearia. The whole of this quartzite series may be 1500 ft thick. It is termi- nated by fm. 75 to 100 ft of a purple

my coarse conglomerate, many of the pebbles are from 2 to 6 inches long and all are well rounded, reddish and white quartzites make up most of the pebbles; then a some jasper, ifreons rocks and tale (like the slate in which the Congl. it), and then maybe some granite or green present. The basal five feet is a coarse sand with occasional pebbles but above 5 feet the whole mass is a troughed bed. At times it is distinctly bed- dded and the shale looks like one bed from the way it heals up but are small beds in the whole throughout its thickness. It makes the base to the Cambrian quartzite. Directly on the Cambrian rests the dark blue magnesian limestone of the Upper Ordovician. Less than 3 feet above the base we saw an abundance of Eridophyllum, some small cupolas,

Schizophria striatula, Cetyba reticularis and possibly Pachyphyllum cordorani, The thickness was not determined but seems to be some hundreds of feet thick. Hifn comes in the Mississippian abounding in crinoidal cylinders, as Dr. also saw Rhypidomella trierei and Cysta- crinus (a first surprise). There is probably Pennsylvanian here also. Below all is a vast area of coarse granite that is "Pre-Cambrian" in age, prob- ably Archeozoic. . . It retains many small millstone grits as is so common to granite. It is the same Pre-Cambrian granite seen in the Wetstone Mts. The Babada all along the north side of the Santa Catalina is much dissected and it is still growing. This is in keeping with what I saw on Sunday. Took a sample of the outer Babada material, taken on the Oracle trail side 1/2 way to Tule Ranch.

"Showed samples of the big conglomerate, and the slate beneath it to Rawson, he did not know what to make of it but said it could be either the equivalent of the basal Cambrian conglomerate seen in the Metacoma Mts., or another conglomerate that is undulain by slate and quartzite which Rawson calls Barnes cong. above, but which Dauten refers to the Pretergne. I rather think Rawson is correct... In any event we intend to return to the Pepper-sauce canyon with Rawson and sort the thing out. Jan 30 - Feb 4, 1924, Worked most of the time on the text-book.

Feb 5-1924. Tuesday, Tuesm. Today at 11.40 A.M. gave my first lecture to about 20 Mining Engineers. Had to do with Inorganic and Organic Matter. The young men were much interested and I had their attention to the end. One man said to me "It is evident that I shall learn much from your course of strict Geology." Besides, I had one of the Instructors in Geol. Mr. Agres and an old prospectin. Abs Langyn Eastman. Worked all afternoon in the Frk. Will lecture each Tuesday and Thursday at 11.40 A.M. and Wednesday at 8 A.M. for the next 5 or 6 weeks. Feb 6-7-8. Worked on Text-book.

Feb 9 - 1924, Saturday. Tucson. At 8 A.M. I am at the University and join Sturman with about 15 of his students to go in a speed truck to Picacho de la Calera when Jones or Jan. 16. First examined the supposedly Pennsylvania li., and after hunting for fossils for two hours failed to see a single diagnostic good one, saw Productus seminetieulatus, and a large Spirifer that maybe S. Ceneratus. The fossils are all very poor as pseu- domorphs. Some of the li., an entire Crinoid. Saw a thickness of several hundred feet. Then went to the bottom of the section just beneath the Cambrian quartzite that termin- ated in about 75 foot of a fine conglomerate carrying pieces of Jasper like the one in Pepper-sauce Canyon. It rests on the Pinal schist, a very ancient rolling material that is cut by Granite.

It is also cut by late Cengrie dikes. I would not be surprised if this old stuff turns out to be Archean. The Cambian quartzite was laid down embedding out in shallow water and thus sand standing of layers is not thick. In places, this quartz- it was folded an on thrust, and Cambrian was a receiver. As this was done before it became a quartzite, the deformation could be due to slipping of the sea bottom. I did not appreciate this conclusion at the time otherwise I would have studied it closer and taken samples. Evidently there are Postergrie sediments of quartzites and jadeite in this vicinity that furnished the pettles for the conglomerate. In other words are here here the Grand Canyon succession in complete development. Got back to the hotel at 5 P.M.

Feb 10-11-1924. Tucson. Inked on rock. Feb 12-13, 1924, Tucson Lectured and worked on rock. Lauson asked to take me tomorrow to Globe, Arizona to see the section there, and especially to collect Devon- ian fossils. Good ones occur here. Raymon Stroganow is also to go. Feb 14 1924 Thursday, Globe With Lauson and Stroganow left Tucson in a car for Globe. Went south via the Phoenix road to Florence and then to [illegible] Superior where we had lunch. At Florence going to Superior one has a fine long distance view of Late Cenozoic lava flows and glaciers that made high mountains.

As one gets to deeper in ore begin to see the Paleogric strata and the mins, all of which is duly overlain by the Devonian Carboniferous lareas. At deeper in we enter Queens Buloh and here the first strata are the quart zites of the Lepache series. This is the Trog quartzite about 200 feet. It is a clean white rusty stained fine preserved quartzite in thick beds. Its disconformably overlain by the Devonian limestone. The first portion [illegible] of elements of the Trog sands bound together by lime and then comes the heavy bedded Devonian limestone. Rarely the latter has a quartzite zone. Fossils are scarce here, but we sees most of them turning the tops. How the Devon is once a lean magnesian bed towards the top the lie are poorer and granular reflect with crinoid elements. Saw nothing of special interest. Then came a most interesting ride through the mountains to Miami. We soon pass through the Carboniferous strata and then it is up

and up through the laras and ask, first of Queens sidek and then the Devil's gulch. Finally one enter a white out. made of magnifite puttrite of late Cretaceous intrusion. This own this man that mineralized the entire area with copper, silver, urn and gold. It probly was this intrusion that hard faulted the globe area badly, and as described by Rausme in the Globe Trib. I have two samples of this granite. I finally get through the granite one and then down through the Cengric lar to Miami. At Miami one turn on all several miles and then last into a little stream to see some jewelt flood of Oceomian, where is the best place for Dev. fossils of far seen. This the re- gulation Hagenbergi fauna may have 15 species or so are had. Then one instead to Globe some sort

max rides and put up The Dominion hotel at 6.30 P.M. Around Miami and Silke the country is very rugged and one is struck by the shaded chequered nature of the hills. The oddities of its are limestones and the reddish ones are of the Apache quartzites, while the green areas, are of intruded durns. See Rausome statement of it. All is due to fault Hocks and the country hereabouts is fear chopped up. In many places one sees quartzite or better quartzitic minerals in pieces of the fault planes. The district covered along the fault planes, and deposited critical masses of recrystallized quartz rock.

Feb 15-1924, Friday. Slate area Started out south of [illegible] and after going 20 miles due south are in the Precal Crownitis where the Apache series, the Perm- ian and Carboniferous are well exposed. Over the Pinal schist with its granite and diorite comes the Apache series. First is the Scarnm conglomerate. This I did not see. It is very much like the Barnes conglomerate to be described later. The Scarnm is a variety in thickness from a few feet up to 30 to 40. At because it is a coarse conglomerate but with pieces of the Pinal schist and appears to be of local rocks. It appears to grade up into guanzites and into the Pioneer shale. I saw much of the Pioneer sandy shale. It is a "dark reddish-brown, often less arenaceous shale composed layers of fine calcic detritus with little or calcareous material." Where more sandy, it is distinctly but irregularly laminated.

In places it is sun-cracked and rain-pitted. Also saw very small ripples. See my specimens. It is the material of mud flats but saw no evidence of marine action pulling up the bottom. The thickness is around 200 feet. Then follows the conspicuous Barnes conglomerate, the arenite part of what I saw in the Pepper-sauce Canyon, see the same plex. The thickness is variable up to 50 feet. All I saw if it was the fallen blocks. It looks like starting a new deposition cycle, and appears to go unbroken into Dripping Spring Quartzite. Did not see much of it. It looks like a marine series and Rausome reports ripples, sun-cracks,

"The Meocal" that Ransome was intended by disinte and smoothal metamorphosed. It is more a lim dolomite. A good deal of what I saw was clear Cryptogam. The leads older not laye but rather the whole area made up a swarg deposit. In the four specimens, Ransome did not see these Cryptogams but I am certain of these beds being algal deposits. Rans- some gives the thickness as about 300 ft. Over the Meocal Limestone is invariably a basalt (vesicular) flow that may attain 1200 ft thick. What I saw was around 25 ft thick. This looks like an unmis- takeable surface flow, and Lawson is certain then is an erosin surface above it. Then another deposition cycle starts in with the Troy quartzite having an average thickness of 400 feet. It begins with a little Al conglomerate like the

"Barres but with small pellets. It is purely euryomantic throughout and very much cross bedded. Some surfaces are smooth and even parallel lined and if undisturbed there are aeolins. Above the center there are several good siphons with or without burrows and an abundance of organic casts now holes about 1/2 wide, long and 1/4 to 3/8 inch wide. I have seen these holes in many other sandstones but what opinions they represent I do not know. On smooth surfaces I also saw unmistakable but small gastropod trailings. These looked like this: [diagram]. I have taken two samples of the current burrows, but the trailings I could not get. This is an unmistakable marine deposit but practically a marine flat with little of water depth. The siphons are all of the current type.

The Devonian limestone is dolomitic in large beds, and hasour almost no fossils until near the top where shells and then limestone come in. Here Atropia (crasely plicate) are common. See the small lot of fossils. the Apache ear Lauwen wants to put all into the Cambrian; the Trog quartzite into the Upper Cambrian, and the rest into the Middle and Low Cambrian. To see the Trog, Chescah and Chipping Spring are unmistakably marine and of Upper cambrian age. I could put all of the Apache into the upper Cambrian and I have no doubt more fossils will be found to prove this. The quartzite The pettles of the various employments Peyersone and Lauwen says come from Portergric formation and good outcrops of them canbe seen about 10 miles to the north of the Selber- Here they lie unmapped across the lower part of Cambrinian Ray area.

"We then rode a long distance over deeply dissected holson deposits. There are three plains here, and the streams are slowly cutting to a still worn level. Back in the Pleistocene or better in the Pliocene the climate must have been dry dry, and much drier than now, or that mountain debris was all preserved in the hollows filling in all between the arks. In the center of the plain occur thick beds of gypsum and diatom deposits sometimes 10 ft more foot thick. Finally we passed Christmas and Omminett and came out into the valley of the Salina river. It had considerable water. At three miles from Drinkleman's, where the San Pedro river joins the Salina, are are in the Pennsylvanian series. Lawson said are more high in the Pennsylvanian. There are rare fossils common. Composita.

Then a 70 mile drive up the San Pedro valley through deeply dissected trams, with the Lara Balliario RR to the park. Finally to Oracle and Tucson. The granite all about Oracle is not post Carboniferous but is pre-Cambrian. Rising out of the San Pedro valley are one or two granitic ridges if the granites seen all about Oracle. Miles and miles of aridose gravel can't be seen here. In this connection study the Slate Folios (III), (Rog Folio 1924 onw out), and Ransom Prof. Paper 98 K (1916) "Some Pal.

Feb 16-19 Sat.-Tuesday, Tucson. Worked on book and lectured on Tuesday, Feb 20-1924. Wednesday. Lectured pm 8 to 9. Then worked in first best, and finished the conden- sation. Write a letter to Dr. O. Dily and sent the Mrs aid letter to Mr Le Vere. Registered, cost $1.68. Write another letter to Le Vere, Feb 21-22-1924. Tucson. Read in Arizona and then on Grea- thm geology.

Feb 23-1924. Saturday, Tucson. With Storganw and his students went out to Prohaer de Caleria about 18 miles N. W. of Tucson. Was there twice be- fore. About the morning climbing around the mountain with the basal gneiss G. guartzite, some hundreds of feet thick, Wanted to make sure that the beds had slumped during their deposition. There can be no doubt about it at all. The slumping is in the laminated beds, either in connec- tion with the conglomerate or without such. The slumping is very local and of varying intensity. In places, it is also brecciated the pieces being very angular. In other places there are local foresetting, but as a rule there is no marked bedding. Some trails are but seldom seen. The conglomerate is of the Archeozoic schist telar with some granite pebbles. There are rein quartz pebbles, but no Proterozoic guartzite pebbles.

Drehu measured the upper Cambrian quartzite limestone and makes them 350 [illegible] feet thick. The underlying Bolsor quartz- itic are several hundred feet thick. The rest on the Pinal schist, a good deal of which I saw, but not the actual contact. The down faulted region to the O.E. of the Bolsor quartzite mountains begins with a little of this quartzite followed by about 35 feet of C. li. Then comes Mississip- pian li that lie almost horizontal. Both are down faulted blocks. The Miss is cliffped about 1000 feet and no C in farther Hood cliffped at least 300 to 400 feet, It cuts out 30 feet of the C. li., and all of the Devonian. In the Miss, the common fossils are ceras and chiefly Ptenophyllum. Saw also Spirifer more abundant & plicata

Friday Spent the afternoon walking over the descending holm of Tucson northeast of the city and the University. The entire hlo son is clearly made up of the debris of the Santa Catalina Mts. Archeogric grains, (rein-quartz), apparently a little of Pinal ochist and Congric alike ared. Much of the material is in inches in diameter and

Pieces of one foot aerom are not rare. I have collected a fair lot of the rock to show the degree of grinding, but I picked out the most rounded ones. The rots are now seven miles away and this material tramp dust washing has been carried at least this far, first down the steppe grade of the tabajada and then out on the real flat plain. Everywhere about me I find a little mine beneath the surface that is caliche. The entire plain is made of these rocks broken to all signs of fire from down to dust. But little of the dust has been away, have not but air away. No red or tons anywhere. The surface dirt is usually a yellowish tone. When cut into it is grayish or dirty white of the caliche.

General Gregory J. Arigma A.E. Arigma in the Plateau Regim of horizontal strata Central Regim (going from N.W.-to S.E.) in the Mountain Regim of sierras with filled in valleys between. The Regim is from 70 to 100 miles and all of the strata are folded. Their trend is "nearly north- north east and south east, but near the Mexican border it becomes more nearly north and south, and the mountain gne as north side eralesces with a belt of north-south ranges which extends northward through New Mexico and divides the Plateau Regim in the east. The northwesting belt of Arigma is described by Seltut as continuous with the Basin Range system of Nevada and Utah, and is considered by him as exhibiting the same prevailing type of geographic structure. He states that his examination "have demonstrated no anticlinal structures, except as minor features. The usual structure is monoclinol demonstrative due to faulting in the Chiricahua and Pinal ranges, and presumably so in many others." With this conclusion the observations em- bodied in the present folio accord? (1).

The strata are Paleogric, resting on marked unconformity upon pre-Cambrian schists and granite.

March 1-1924. Tucson. Saturday. With Stroganow and his students went out to the isolated dip near Picacho de Caleña. The dip is a syncline pitching about 20° to the N. about 20° W. It is an isolated men separated from the two dips that made up the Picacho by bolsons. All in limestone with a few zones of hardened sandy shales or even by greenish shales. The li, are thick bedded from Total thickness seen 400 or more feet; 350 measured. 2 to 20' at a time. The fossils are common though few good ones rather not as pseudomorphs. All in regulative Pennsylvanian with Phlebo camaratus, A. rodmontanus, A. g. striatus, Productus semireticulatus, P. punctatus, P. scabriculus a setta nebrocensis, Crayinifera Impiripinus?, Martinia perplexa, Embrocelia planconvexa, Compria suttilita, Campo- phyllum torquium, Chaetetes millacraecus, Stenofna sp., Archaeocidaris sp. in's and plates, thick spiny plates of Crinoids, Phipidomella pecor. It was interesting in places to see the li. weather ing into small rounded balls from 1 to 4 inches, the

rounding being due not to rolling, but are due to weathering. The limestones have much cheat but all of it is due to weathering. Weathering will exceedingly commen. The weathered tiny joints that break or much of the li., is often removed and this criteria perhaps gets but little into the bloom. On all sides from this li. not there's a that bahajada of cheat, small pocketed pieces of li immersed in a brownish soft soil. It's all my loose or that mes fort steps are depressed an wet a or. This soil can't be dust but more especially residual clay from the li. Everywhere the surface below the bahajada is a flat surface and the pockets show cheat marks. Of actual markers there are but few and the bloom is here remarkably flat. Perhaps there is no water flowing out of the bloom. The bloom is very wide and extensive, and I saw but little of it.

March 2, 1974, Tuesday. Sunday, Today is a windy and gusty day. The air is grey and the air is full of dust. The wind maybe blowing 30 to 40 miles per hour. It's from the south east. Now I can see that much dust is blown about, and even the sand will move today. However there can be few days like today since the photos of the dunes show but little wind having a polishing. Everywhere in the dunes the ditches stand in a little defect almost a foot above the general level. Some of this is due to the rush holding material, but in the main it must be due to sheet-washing removing material of the dunes. If this is true the dunes must be losing material at the present time.

March 3-1924. Listened to the lecture. Party delivered - still on my notice. An illustrated lecture on "Features of Desert Vegetation of the World," will be given by Doctor Daniel Trem-bly MacDougal, director of the depart-ment of botanical research, Car-negie Institution of Washington, and head of the Desert Laboratory, near Tucson, and the coastal laboratory, at Carmel, Calif., at a meeting of the Tucson Natural History society Mon-day evening, March 3. Dr. MacDougal was in 1890 a spe-cial agent in botanical exploration for the United States department of agri-culture. Later he became a member of a commission for the establish-ment of a botanical laboratory in the American tropics. For 10 years he was editor of the Journal of the New York Botanical Garden. Previous to becoming head of the department of botanical research of the Carnegie insti-tution he was a university teacher and at one time director of the New York Botanical garden. In his trav-els and studies of the world's deserts, Doctor MacDougal has gathered more than a thousand slides illustrative of the peculiar and interesting desert plants found in the Old and New worlds. A selection from this collec-tion will be shown Monday night. A short business meeting of the so-ciety will be held in the auditorium the same night at 7:30 p. m. The following items of business will come up: Tucson Natural History society proposed revised game code for Arizona; constitutional amendment changing time of election of officers from Jan-uary to May; recommendations re-garding Public Shooting Grounds Game Refuge Bill. The attention of all who are mem-bers of the Tucson Game Protective association is called to the fact that an adjourned meeting of that organi-zation will be held in the district court room, county court house, at 7:30 p. m., Thursday, March 6.

Emeritus Professor of Geology Will Lecture at University Tuesday Evening. Dr. Charles Schuchert, emeritus professor of geology at Yale univer- sity, will deliver the first of a series of two illutrated lectures in room 208, Mines and Engineering building, at the University of Arizona Tues- day evening, March 4, it was an- nounced yesterday by Dean G. M. Butler. The subject selected is "Marine Sediments and Their Bedding, and Disconformities or Breaks in the Geologic Record." While this lecture is intended primarily for the stu- dents of geology and mining en- gineering at the University, it is open to all who may be interested, the dean stated. Dr. Schuchert holds the degree of A. M. from Yale university and LL.D. from New York university. He has been connected with Yale since 1904, and since that time has held the positions of professor of paleontclogy at Yale, professor of historical geology at the Sheffield Scientific school and curator of the gelological collections of Peabody mu- scum. He has written very exten- sively, and his text books have been widely adopted. He is lecturing this spring in historical geology in the University of Arizona. The time and the title of his second public lecture will be announced later. Lectured to about 30 students and gologists

March 5 - 9-1924 Tucson. Did all the regular things as to heretofore, but nothing out of the different. March 10-1924. Tucson. Packed the boxes collected during the morning. Three boxes that will go by Express, wrote some letters. Got the R.R. ticket for Marathon, Texas for Friday night. March 12-1924. Tucson. Wednesday Shipped by Express the three boxes pre- paid $13.00 freight 116 pounds. In the evening gave a lecture on The Sites and Nature of the N. American Geographical. Had an audience of about 30 men. The lecture went off well.

March 13 - 1924. Tuesm, Thursday, at 11:40 G.M. gave my last lecture in Hist. Geol. It was on the Devonian, and was the 18th lecture. In addition gave two evening lectures. I merely lectured once on a rare marine fauna (Fragiella) in America. Then packed up the two boxes of slides received from Yale. Will be shipped Eas. before. Opened the third box of slides, just received for Devonian. When the negatives for paleontologic charts, that I will depart for Storrsnow to have charts made of. Later on he will return the negatives to me. Gave Storrsnow a copy of the 60e. ed. of my Text-Book as a present. Mr. Eastman, a lawyer of Grand Rapids, Mich., took in all of my lectures. Also an old mine prospecta. Also Mr. Rogers who will print up my lecture notes. Left the entire self Hist. Geol.

lecture arts with Stganow, who will of them and then return the set to one. About the evening with Dr. Frederick E. Clement discussing historic taxonomy that he presents or writes in his book "An Ecologic View of the Green's Con- ception (Rev. Pub. No. 326 of the Car- degie Institution of Washington). His views are the correct ones, and I will adopt them in my Handbook of Brachiopod Genera.

March 14-1924, Tuesday, Friday. Packed up during the morning and adjusted final matters for my departure for Marathon, Texas, late tonight. Then had farewell lunch with Professor Horganow and his family. Got back to the Santa Rita by 3:30. Spent rest of afternoon reading. Spent the evening at dinner with Dr. Clement and his wife. The other guests were Dr. Parsons, Dr. Cherriman and A. Butler. Had an interesting evening. Mrs. Clement paints our own wild flowers and has long been out on her head and out abroad on wild flowers of the Rocky Mts. Published in New York in two forms, plates with text four pages of text, and another with some text. The next book is to be by herself on Wild Flowers of the Pacific Coast.

"March 15 - 1924. Saturday Set off at 6.40 A.M. at [illegible] we are still in the H[illegible] county, but the mountains of eruptions are usually on or high here, but the plains are higher - about 4000 feet. The desert is here sandy and covered with very small dunes, some bunch grass, but mostly small greasewood, sage and stunted yuccas. In places there are [illegible] furs far away to the north. About 10 o'clock past El Paso we saw then / 2 were approaching the trail of the Rio Grande. had lands cut through the H[illegible] deposits. All is soft muddy yellowish sand with redclay and replete with granular grains of calcite. More than 100 feet I depth may be seen and all of it has grains of calcite. The Calcite mother-white. The bedding in plain is so regular and in the grain that it could be flag deposits. As one approach El Paso we appear to go through of the basalt, but it in light ochre color and is probably for sand crushed.

and is covered in road metal. El Paso is a brick city with many tale buildings: We begin to get the architecture of the eastern states. All the workers along the railway are in the main of Spanish people. Outside of the city it is as much the desert here as at Tucson. It is a cool morning and the hardly public are on streets, but the natives appear to be lightly clad and some are in shirt sleeves. Mile after mile to the east of El Paso the R.R. runs along the valley of the Rio Grande coming falling to the deeper desert plain. One afternoon has a good view of the shallow valley and its wide flood plain, much irrigated land on the high flood plains seems here red cotton and fruit appear to be the main crops. To the south we can see about 20 miles one has deep canyon points and the flows dip south into Mexico. Is this due to fault blocks? certainly are in California. At about 30 and 40 or less then in valley and now modern farm sets to the north of the Rio.

In the region of Tosca (Montoro Cerrum) refer think a series of much folded strata I see a closed syncline overthrust to the north or N.E. Are these Campanian strata? Where did this great mass of sediment come from? All appears to be soft stuff, muds. They must have been Jurassic elevation in this general area to have furnished this debris. Where was this land? To the S.W? Above the great mass of mudstone come in thick zones of impure limestone. The dips are usually low, but in places are nearly vertical, At Sierra Blanca the R.R. comes around with low dips of the Crest. This is a little town and one could get hotel here. Altitude 4572 feet. All low dipping Crest. to Lotro (3943 elevtn) with local sharp dips. Between the crests are sparse lilacss, mostly four good thickness of strata. All the way to Valentino it is Crest plain with outcrops in low crest region. Elevation 4424' It is plains country all the way to marfa

(= Fort Davis). Maybe altitude 4695 feet. Looks like Cut, ground all the way. His farm land with sparse cattle on it. See last page of January 12-1934. Ignem rock begin to appear a little east of summit. Brt to Marathon on time at 4:08 P.M. Put up at a family

Marathon, March 16-1924, Sunday. Spent all day mainly 4½ miles out on D.P. R.P. to study the Tesnus formation, see other book for detail. March 17-1924, Monday. Too tired to make an all day trip. So looked for a Ford car and man to take metmannus to go over the Leonard Mt section. Will charge eight dollars per day. In the afternoon walked south of Marathon about 1½ miles to study the Paleozoic areas as exposed along the road cut ups and in the fields to the east of the road. Got enough points to show one that I am in the Trentman series. See other note book for detail.

"March 18-1924. Tuesday. Marathon It is a cold, overcast and foggy morning and rain not a little snow in the air. Under these circumstances will not go into the field until it clears up. The wind from G.E. did not change and it was miserable all day. Along two- some day sitting around and reading. March 19-1924, Wednesday. Marathon. A dark morning and lo it has been snowing during the night. The mountains are all in clouds and at light red out they are to be seen all covered with snow. By 8.30 the sun is out at times and it once looks as if the storm is over and that it will clear up. Talked over the situation with the Garage man and he advised me to delay until tomorrow when the snow would be out of the cars. Another long day of waiting ahead. Finally decided to get a car and man to take me to Raymond. After going 3 1/2 miles the Buick broke something and we had to walk back to Marathon. The walk was in the teeth for cold strong wind. Drifts in western Utah.

Marathon, March 20-1924, Thursday. Took a Ford and a boy Chaffee over to Osceola to get the ammonites, gotten here first by Sudden etc. Got about 60 specimens, of which about 40 are good. They are all on hand. The associated fossil looks to me like Cider. For full account see other book, Marathon, March 21-1924. Friday With the same Ford went about 18 miles northwest to the junction of the Road Canyon into the Bellam's canyon. Came here to get the good Ammonites. Got one hundred or more. All are good pseudomorphs, and got Bice had no better material. Packed after supper Tom Boyce &

"[illegible]", and get ready to leave early in the morning for San Antonio. Marathon, March 22-1924. Saturday Left off at 6:15 A.M., and shipped four boxes of fossils by Express, Elliott, Checked my large hand bag to San Antonio, and at 7:55 A.M. was off for San Antonio. Looking from stage-road to the north- east, one has a wonderful view of the Teconus Staff dipping sandstone and others are planned to a plane upon which the Comanchia can be found; just to the south of Teconus one has the best view of this grand unconformity for less than three miles. The Teconus north of the railway dips beneath the Comanchian. At 1:10 P.M. one sees the Rio Pecos, the water today is deep green, evidently clear water.

with mud lime in solution, due to its flowing through the Comanche limestone. It is a tiny stream, and the present rain now only has eroded this deep hole, or 3 1/2 feet deep. As I saw it today it has this profile We cross North River at 2.00 P.M. It is a smaller stream than the Rio Pecos but like it; the water is clean and clear. Del Rio in the valley of the Devils River now looks like Scott county. Much vegetation here and the hills are either newly plowed or as green as the Emerald Vale. Of course it looks to me this way coming out of the semi-arid

County. It is still semi-arid here, but in the area of irrigation it looks like an oasis in the semi-desert. Elevation 964 feet. From Del Rio the country improves more and more agriculturally going east, and then carriage way to San Antonio we pass through a cane and grain growing county. Inne and more towns come in, but all are small similar to ones quite of Arizona, with here and there an orange park of considerable age. We get on train (8:00 p.m.) to San Antonio and miss a cab for Crockett Hotel for the night. All goes well and I am rested, and happy in the thought that I get the true idea of commuters in the blan Out.

San Antonio, Texas March 23, Sunday. A fine bright and warm day. Not a cloud in the sky. Walked around the center of the City, said to be the lay-out one in Texas, for an hour and then back to the Hotel. San Antonia does not at all look to me now as I remember it of 1906 other on my way to Mexico City. I remembered the Alamo, but all has so changed in the last 18 years that there are no other land mark. At 10:30 I am off in a Studebaker new car for Austin. It's the Red Ball line very fine, and there are other auto lines to Austin. We go through the German settlement of New Braunfels where my father brother settled in 1865. The signs on the stores show German names, and one 90% of the people are Germans. It's a town of 7000 to 10,000 people. The turnpike runs fine all the way.

"The next event throught San Marvers, a large place, and a little lording town. And the road was not hard but we got over it at the rate of 30 miles per hour. We passed trough one large village, and Buda near Austin was the only one meeting, it is 87 miles by road from San Antonio to Austin. All the hotels at Austin are said to be dirty, and the cleanest one in Luto Hotel. It has no charms for me, and besides has my rooms at $2.00 per day. A first hotel in building and in any comforts more the travelling public can treat comparatively. Later full of some clothing that I have and myself into the After my arrival I walked up to the Capit- of built red granite. It is large and impressive. Large grounds all about it, and the walk up to the Capitol is lined with monuments com- memorative of the Confederates dead. Their inscriptions do not hide their feeling, on the statements that the north defeated them; site from keeping the Constitution - State Rights-and that they had the site to succeed for the Union.

"Died in State Rights guaranteed under the Constitution in. The people of the south, animated by the spirit of 1776, to preserve their rights, withdrew from the Federal Compact in 1861. The North resented to interfere. The South, against overwhelming numbers and resources, fought until exhausted. During the war, there were seventy-two hundred and fifty-seven engage- ments; in eighteen hundred and eighty-two of these, at least one regiment took part. Number of men enlisted: Confederate armies, 600,000; Federal armies 2,859,132. Losses from all causes: Confederate, 437,000; Federal 485,216." On the front face of a monument to the "Southern Confederacy" erected in 1901, by states guaranteed on its facing sides: S.C., Miss.; Fla.; Ala.; Georgia; La.; Texas; Va.; Ark.; N.C.; Tenn.; Mo.; Ky. Met Prof. [illegible] and his wife out in their car, and Dr. Lovest riding with them for a time. In the evening had dinner

Together at the Marcell Restaurant. Austin, Texas March 24 Monday, Called in Dellards first and talked with him for an hour. Then talked Mara- than geology with Hidden, but I do not see that I can follow him in his several interpretations about unconformities. The so-called Astrereal amites from the Moon Taurus seemed to me to be casts of orrid. Certain I saw no orrises, Therefore there is cart evidence as to the age of the Taurus. The green formite that I saw Hidden is willing to accept, but he he sees altogether too many angular un- conformities. Hidden still insists that the star is not Lemaril, and that there is at least a very marked crossing unconformity between the star and Lemaril. The only interesting thing be should

"One core feet in one 1200 foot long trough arkysdrite, or this thicker than not more than a foot of black shale. The greater part of the arkydrite is very regular laminated. The arkydrite layers are usually about 1/2 mm. thick, and could count something like 10 to 12 to the inch. Hidden interprets this lamination as due to seasonal oscillations, and believe that it took about 300,000 years to lay down the arkydrite. According to my calcu- lations I get 144,000 years. 1200' 1/2'' 24000 1200 1240,000 tank print years 144,000 years by them. Hacks tanks. This maybe from carbon dust and organic material. Hidden thinks he has in his headlands and others get an abundance of Radiolarians but during time that I looked is more like such. Below the arkydrite is much Hack

Hole and in it has been found according to Breese several specimens of brown am- onites, near two specim. Riddle thinks the age of this anhydrite is Cretaceous. The results he completes with the Fidsia dolomite. This locality of the diamond drill hole is 90 miles Ch. W. of Salem City, It is a most interesting find and some thrilling climatic results should come out of it. The climate was dry and apparent- ly very arid; during the winter the anhydrite was thrown down; this, in the light of the matter. The tomb appears to be graded in Cretaceous years. Had dinner at Lillard's home, and after dinner several Yale graduates called, Returned to the hotel at 10:30. Sunset appears to be coming on.

Austin March 25, 1974, Tuesday. After the morning until the paleontologist Whitney, a graduate of Cornell, Dr. Roy Simmons. Whitney is at work on a list of species of echinids. Thanks the Cretaceous may have from 100 to 200 species of echinids all told. As for much new material among the mollusca. The type specimens of the Oremble being are now in his charge. Whitney has a strong mechanical bent and has a home made and very effective camera for photographing small things, especially the forams. He has been interested in them since 1917. Hadden began to use them in submarine work about 4 years ago. In the afternoon rested and got ready for the evening lecture on the deep-sea maps of the North American Continent. The lecture came off to an audience

I am at 70 and all appeared to be much interested. It was a good audience to lecture to. Professor Glasscock also attended. Prof. Hidden introduced me and as well Professor Simmons. The latter writing a book on the Physiography of Ohio. Austin March 26-1924, Tuesday. Packed up and left Austin on Southern Pacific for Houston at 12:35. Set for Houston at 6:20 P.M. Put up at Rice Hotel. Houston, March 27-1924 Thursday. Attended meeting of the Amer. Assoc. of Pet. Geologist, in the afternoon presented my paper on the Value of clay and minute fossils in out- shore stratigraphy.

ation. In consequence have taken a Cold the more me in years, much confusing and not as alive as I have been. Houston March 28 Friday. Attended the morning session of the A.G.P.G., but did not get much bit for, due mainly to my cold. Did not take in the afternoon ap pearing to the humble oil fries or salt doves. Nor did I take in the Banquet. Engaged in trying to loosen up, but my head is round stuffed up and my nose is beginning to clog. If I was out in such good health for the original trip things might be much worse.

"Austin, March 29, Saturday, Had myself investigated by Robert Spearman, and he said I had nothing especially to fear. I called on him be- ause during the latter part of the night I had a little fever. Listened to the Salt Dome papers. Olson was very cautious in finally de Sigen stated Harris theory of salt crystallization, (2) Plcanic theory and (3) Tectonic causes. The opinion I reg mine that salt beds exist beneath the Crastal Plain and that those due to Tectonic causes have risen into Cenical domes. I pointed out that in theory on the subject they should not found the high points in geological bed. That they were times of salt analysis and times of tectonic movement. I also said that I did not believe them in any Permian (Permin) salt beneath the domes. His point of Comanche gas.

In the afternoon session, Hande- was taken on Green River sediment, interested me most. David White spoke of what he saw, and held that fresh- water algae played a part in it, and that the sediments were laid down under arid conditions. I sat up and added that the climate was rather cold and dry than warm and dry. Since no red beds and the preservation of carbonaceous materials. The idea that carbonaceous materials can only be preserved under the in- fluence of salt water may have to be abandoned. Under arid conditions salt is always present, but very little under cold dry conditions. After the meeting with Dr and Mrs R.F. Baker.
