August 4th 1918: Sunday, Cow Head - Lower Head A fine Sunday morning from head but the sand is m-shoes and one cannot go to Passam Pond. At 8.30 one take the launch south to Lower Head which is at the northeastern point of Hall's Cove and one finds landed safely through the breakers. The cliffs here are about 20 to 50 ft high. The cliffs here are a white fine crystalline limestone. A great many Chazy fossils here are (m.e.-3rd, directed) Li with dinosaurs on the outer at about 600 ft (from here into the sea) and in actual liddings it is difficult to determine when it be very practical. These just above sea is only the other 400 ft. It is founded by Hardy Chazy conglomerate some of which in this side. Halls are full of Ordovician Productus. Trilobites are common in the foot mass and we see Otho, Reneta, and Promontories or both. The horizon appears to be rather Taffle Head than true Chazy, although Brontos is very common. To the south of the li. coal at low tide maybe seen hundreds of feet Passam pond time. The cliff here 4-5.60 E. Come for northward around Lower Head one see many other large Chazy masses one to 50 ft across and another may have one more than 300 ft across. The liddings in this Hroll is really practical. fully Ordovician Productus. The masses are true large lags, some of the and are irritably out of the Chazy itself. Smaller Halls are of an intrusive formation of conglomerate. All the prices appear to be of Chazy age. No depositional reading of the li. coal is visible. It is a better shelter mass, and in the region of large Chazy masses, north 1/4 mile across. To the north of Lower Head the head ends in a little sandy core 350 ft across. On both the south and north sides of this one sees Phyll spars Phrag On the south side are bristling Phyll spar stones (Hornstone) and Whales, Li, and Hall sheets in thin beds as at Cow Head. It may be that the sea has eaten out here are those non-resisting beds in which case then is a thickness of 350 feet of bedded limestone in one mass, the length and depth of or Hroll their dip is 60°S. 60 E. which is unknown.

A part of this cliff is in a wide flat roof of greenish fine grained sandstone and chaly sandstone. In the roof it once looks like large hard conglomerates, in places one sees that this sandstone was laid down under stream or wave action for it has inclusion of itself up to 2 feet by and some of these pieces are transverse to the bedding or that they can be no mistake about their big inclusions. Towards the top of the exposed mass is a zone about 10 feet thick that's very porotic. They are many small sub rounded quartz and many red pebbles, pebbles up to 1/4 inch across, but with those the greater mass is made of small and large pebbles (up to 6 inch by) of greenish dark blue, red hard cherts, black chert of the bellment ore and sometimes (up to several inches) although in its general aspect it's a unit unlike the Loron Bay in the Evidently this is the Loron sandstone. Dip already lies southwesterly 60 S. 60 E. Across the strike one sees about 1/2 mile of strata and the thickness seen in them at least 1100 feet thick (not all is seen) and not 700's as apparent from clear roofs are at least one mile long.

"The Parson sandstone strikes into the land and must make the shore north into Parson Pond. Trouthful describes the dip of the sandstone as increasing from 65 to nearly vertical at the Pond entrance. When at the Pond we must go south for a mile or more to see these relations. North of Lone Head where we saw the actual contact between the Parson sandstone and the Cow Head li. cysl., the contact is an irregular one. The irregularities seem to be as great as 20 feet at least and on it followed less often small lready li. cysl. and more often the thin bedded over those the bedded tri. cysl. of smooth agates, and then the partmen.

How long this time interval lasted can be interpreted from other evidence.

That the Parson sandstone can not be included in the Cow Head cycle is seen in that there is no transition from one into the other. On the other hand than a transition from the Tattle Head series into the Parson sandstone at Tattle head. It should be emphasized that the Parson sandstone in its general characters remains much of the "Celtic" sandstone of the cranegatual the Harford and Bonne Bay series. deria and of the Bonne Bay series.

August 7-1918, Wednesday Parson Pond. A dark but clearing morning. With middle tide at 9.30 we start with the boat cruise along the north shore as far in as we can get. At 10 we are actually started and at 11.30 a.m., we are at the very head of Parsons Pond at the foot of the mountains and in front of a small river known as Middle Brook. There is another one to the [illegible] South known as South Brook and yet another one about half a mile to the East known as East Brook. As we go up the Pond one nowhere sees any cliffs and the shores are marshy and swampy to the very edge of the water. The shore with its smooth granite boulders are nearly everywhere swampy and lie in the marshy shore. A once unpromising place to work out the gologic sequence is hardly possible. The inner part of the Pond is deep enough at all times for one boat, but the outer two miles one boat can go from middle to deep tide. The present opening has been made artificially dug and is a precarious place to get in and out of for a boat drawing 3 feet more of water. Steam might be done at high tide in calm water. As we near the head of the Pond it becomes plain that all of the mountains flanking it and extending to the south and north are made up of bedded rock. One great precipitous cliff can be seen from the sea or the village of Parson Pond to be of strata dipping to the south- [illegible] East. The southeastern and eastern shore are all of Portlandic age and apparently are of marble. On the southeastern side about 1/2 mile to the south of Middle Brook there is a precipitous cliff and other

He then went up Middle Brook and everything he saw Paternocian onatles. To the north of the man dipping south- east there is a marked fault letting down a head with a similar dip and further north all the strata of the same mountain stand to end. As we looked about here it is plain that the geology of the Paternoic is very complicated. They can't the Paleogene as the shillum in [illegible] along the Pond. In front of the Paternoic mountains, the land is very low usually under 10 feet and in general does not rise to much on 20 feet until some distance from the lake. All is late Ordovician strata. I was landed at East Brook and here was a small head all made up of small pieces of a finicle green and black shale one of which was almost yellow. Evidently the lake bottom here is made of this shale. Outcrops there are more. I then continued to march it along the north shore but saw no out cliffy ledges until about half way to the red wells. Here I [illegible] dipping about 300 from N. W. S, saw a small ledge but only three pieces of a fine grained laminated sandstone tending to be limy. About 1/4 mile east of the red wells that near drilling park near the land makes a point and here there are good exposures of the strata. The average dip here is 40 to 45 deg S. 70-75 E. but there are local turns in the strata. Evidently there is some masking. The strata dip towards the mountains, the

They have many stau- rolagites, polidogonema, lincaulus, etc in several zones through a thicker of about 75 feet. Loom appears a limestone conglomerate in which the shells are small and sub-rounded, and beneath it are thin bedded blue limestones with their interwadded shells. Then follows more Li. congl, probably 20 feet thick but in several zones. At the rid denials there are brick red shales (congl.) of which is plenty in garden beds, into these the ocrels have started and I am told by Mr. Bland and that they penetrate about 30 feet of red shale. Still further down are more Li. congl. like those above, and beneath one greenish shales and sandstones. The total distance across this point examined is about 1 furlong or a little more. doubt as though it was half mile across but to me this is too much. From this evidence it is clear that all of the Palaeozoic strata seen today are of the upper part of the Cow Head conglomerate, and not at all unlike those seen at the Damaris of Paulo Isles. As we went east of the Pond this morning there formed a hill and prominent hump on the south side known as Parsons Pond Hill. There must be some hard rock in it to make this prominence and our surmise is that it has the very hardy Cow Head congl. like that of Loom Head. It seems to be in line of strike with the congl. of Loom Head. Returning to the village we then travelled south along the Gulf shore for a mile to the south side of the marsh where once the sea entered into a that maybe united with Parsons Pond. Pond.

As our boat is too large to get admr. in Parsons Pond we enjoyed a fisher man's dory boat and with one drag to land in left the village at 8 A.M. headed for the inner end of Parsons Pond. Got back at 6 P.M. having measured a section nearly three miles long. This section is described in detail below. (they stand on red shales) He started the section at the upper oil wells and briefly described yesterday. It is from here less than 1/2 miles across the strike to the Portu gneic rocks, in this distance I judge all the rocks to be of the same series as those to the northward. These to be added to the section described below. All of the strata give evidence of being deposited in very shallow water and outside of the grafitolite and my small Lingulas we sees no prints, nor even fusoids or worm borings. The sandstone and shale sandstones all show the effect of grave omr, a sort of riffing. The shales are certain of shallow water. That the thin bedded lie. are also of shallow water is sometim thrifty and seen in that they are always accompanied by intraformational conglomerates. The li. engl. of Parsons Pond have nothing in common with the Carr Head conglomerate. The latter is made up of large blocks while those of Parsons Pond are all of small pieces (usually if then lie, 1/2 inch to 1 inch thick and from 2 to 6 inch long. At rare situations one sees pieces up to 18 inches across) and subrounded. At other and rarer intervals the conglomerate is made up of small angular pieces usually all under 1/2 inch across. These gives show the dense character plainly and the thinner grases are probably also all lenses. These Congl. are never always associated with the thin bedded dure colored lie.

August 9-1918 Friday, Parsons Pond - Daniels Cove It rained lightly during the night but this morning tends to clear. There is no wind to amount to much and one projects are sure that we can go north. By 11 A.M. the tide is high enough to get on the bar, and we grove at that hour without difficulty. The bluff east north of Parsons Pond is all glacial sand and the cliffs are about 35 feet high. Here are no native rocks visible until we get six miles north where "The Arches" are. Here are gr ashes and are surprised to see that the Arches (there are only three of them), one fell may this past years ago during a heavy thunder storm, and long before this must have been two others) are all composed of a light and dark eluted dolo- mitic [illegible] breccia. The rock is much fractured and give the appearance of a pure breccia. The whole appearance of brecciation may however be due to delimitization, (or other rocks are here visible though on shore we see similarly at the Parsons further out in the sea.

These dolomites strike into the land to the north and close by the inland (3/4 mile from shore) (Ten 2 miles out of they arches.) great misty facing cliff of Portland Head (530 feet high). This cliff shows the strata dipping somewhat or southeast at a low angle perhaps not as much as 20 degrees. About 2 miles north of the Arches are gr ashes and gravel, mile north where we have lunch.

If or there should be a fault to the north of Portland Head. Just what sandstone this is I cannot get tell. It maybe the one below the Cow Head conglomerate or one in the Parrot Pond series. I hope to clear up the matter during the day. Later the fore conclusion is that it is the sandstone below the Cow Head conglomerate of my two sides, across 1/2 mile and goes over 100 for ashore again just north of the mouth of Portland Creek.

All of the li. crgyl seen this afternoon appear to be ground up in the main Table Head limestone. In general the pieces are under three inches across though others may be up to 18 inches long and an inch in thickness, in this mass of angular pieces lie scattered far apart small blocks angular up to 2 feet across of a nicely white kid-sege like li. It is astonish- ing to see the uniformity of the material, nine-tenths of which appear to be of Table Head derivation, and the rest majority of it ground up to small pieces. There certainly is some Chazy fragmental in it. Nowhere did we see the slightest indication of bedding in the ground up material, and bedding was not seen in the large blocks one of which stood nearly vertical. This bedding is that of the blocks before fragmenting. About 2½ miles north of Portland Creek we saw two cliffs developed elevated beaches. The lower one stood about 35 feet above the sea and had a width of about 20 feet. Back of it was a cliff 15 feet high so that the upper beach was about 50 feet above sea level. For 2 miles north of Daniels Headon are the cliffs all of fine-grained material. Granite boulders are large and It would seem that the fault beyond at Lown Head con- tributes to the crest of Parsons Pond Hill and Portland Hill. After supper we went out to see the li. crgyl of Daniels Harbor than those of Portland Creek and in It is a more rocky crgyl made up in the main of Chazy pieces as the may be to 6 or 8 feet across and masses of Table Head thin-bedded masses up to 30 feet long.

"August 10 1918, Saturday, Table Head, A light rain during the night and this morning it is dark and misty. As then in our mind we propose to go to Table Head as soon as the tide heats one boat and can get moved out of this tiny striking "Daniel Horton". We do this at 10.30 A.M. The first 3 miles are placed drift and trueness, altitude about 35 feet. Three miles north of Daniel Horton there is a 2 1/2 miles long exposure to Bell Burns of the lower Table Head series. The strata are a sort of lightly dark grey thin reddish bi without any shale. They dip into the sea at 25° N. 75° W. and strike along the coast undulating somewhat as one for north foot then, and exposing somewhere between 100 and 200 feet of strata. Fossils are exceedingly poor and almost all are of fragmental trilobites. At 12.30 we begin to pitch camp beside a wrecked American dock-er near the foot of Table Head, among the low overhanging bushes, and upon a husky floor. It in the pleasant place one have been in. After lunch Duncan and I go south along the shore to see the strata along the fault line. There are no exposures from Table Head for about 1/2 mile, and then for one mile to Bell Burns one sees the Chazy and the basal Table Head dipping in opposite directions. At first the blocks of Table Head are seen to stand on end and beneath a cavity there comes in a Chazy dolomite. This dolomite series one then follows into Bell Burns where it goes beneath the Table Head series that this extends along the coast southward for 2 1/2 miles. Of the latter dom- hein thinks there may be exposed in this distance from 300 to 500 feet of strata. The total thickness of the T.H. is 750 feet.

August 11-1918 Sunday. Table Head. and bright A fine cool Sunday morning, we start north on the fort path to a place a little more than 3 miles from our camp at the south end of Table Head. Here we see low cliffs extending north for many miles and along the strike of the rocks. The strata are thick beds of a dull-grey fine crystalline dolomite full of calcite interlenses. No fossils are seen. A very little of chert (strips) cropping out replacing the calcite strips. There are also small quartz geodes. We started to make the section 3 miles north of the south end of Table Head. Here the lower beds are exposed in a little rocky cave made in the upper part of the Reed Mountain and almost continuous use of green broken more whitish than shunier here. Pyritous chert followed a few feet higher by Euchasman (matter unknown) Coral-fern type spore and many flat gastropods, coming then a very large Helictoma beds (and was between 5 to 10 miles apart). There are in zone 2 division 3 of Richardson. Up to the block just north of Table Head Deuter made out 115 feet of thickness. He must abandon all of Richardson's descriptions as they do not fit the rocks as we see them. This division I is certainly the terminal beds of the Reed Mountain. They cannot be referred to the Chazy. The terminal beds of the Reed Mountain are well seen in the cave between the block ½ mile north of Table Head and the north end of Table Head. Here near the base are globidymograpus in li, and a few small Hornitoma likeforms. The contact between these beds and the Chazy is well exposed in a low cliff running out into the sea, very bedded Below is the unmistakable Reed Mountain magnesian li, and on its inner surface with irregularities of one foot depth comes in at once the thinly dural li. of the Chazy. A few higher appear characteristic Chazy mids. This relation of the two formations is done just like

All slept cold last night and Duntan got up before 5 made a fire and sat down to do it until breakfast time at 7 AM. By 7.30 we see our boat coming of from Daniels Haven. The wind is mild and favorable for our trip north to Potan Choix. We left at 9.30 under favorable conditions for a 26 mile run. At 2 P.M. we are in the Fort Haven since we left Bonne Bay, at Old Potan Choix known as Potan Choix. We pitched our tents on the grassy shore and before we got finished it began to rain - a misty rain. As we traveled north this morning we had a fine view of Talle Head... The Redmantum strata extend north in an almost continuous exposure for six miles. In all this distance the strata undulate up and down or that is appeared no other beds are exposed than those are saw on Sunday. At 6 miles north of Talle Head the and finally disappears at about 3500 strata begin to undulate with steepen dips. They blend into the more decided undulating character for another mile when the cliffs are all of special gravel outcrawl. In this last mile of exposure it is fortunate that the Chazy green comes inland undulating in other places. The dipping of the beds inland, shore continued, maybe no more than an From 7 miles north of Talle Head the shores appear to be all of glacial material and with local exceptions appear to extend to Hantle Bay. The gastropods I collected in 1908 at Shell Bay may be of Chazy age, this is the view Duntan is inclined to take from a study of the specimens. All of this coast is low and along the shore hardly exceeds so far. Here one sees in faces two eleventy terraces, the usual levels of 30 and 50 feet. There

It is a puzzle to what great period the layer of pelecypods could belong since they seem far later than any of the gastropods present. About 2/5 of a mile from the north point of the peninsula we find a layer full of large trilobites and a little ostracod. This layer continues near the upper part of the ridge to the point where it is at the top of the strata in the high cliffs. These fossils are limited to a thin zone of not one foot thick.

This morning the skies are clear and the wind is light, we therefore prepare to go to Keppel Island and Hantles Bay to the south of Point Pick. At 9.10 are are off. It in 1/2 miles to the return point of Back Arm and 6 miles as the train goes to Point Pick light house. It is another 5 miles to Keppel Island where one or other near the middle part of the north shore. We then crawl to the return northern side and or in around to ready where are started. We did this in 2 hours. At first the rocks are deep redded dolomite with thin groves of laminated dark blue to almost black li. Hardly any fossils are to be seen but occasionally there is a trace of a depressed gastropod. The thickets show traces of our crawling. We learned not tell what the age of the rocks are other than Beckman town on the basis of lithology.

Aug 17, 1918. Keppel Island - Hantles Bay. As we go around the small side of Keppel Island towards the east we see thin zones of laminated clay, in completely unweathered. Fossils are accordingly very scarce. Duntan thinks there may be upland on Keppel Island about 20 [illegible] feet of dolomite beneath the semi-cracked beds, followed by less than 50 feet of the latter. The strata are almost horizontal, though hardly they undulate in some places with the formations all atwitter. At 2.30 we are aboard again and start for Hantles Bay. Duntan's notes for the afternoon areas follows: "As we enter Hantles Bay we pass between the southern mainland and House Island in the mouth of the Bay. This island is formed of Blue- mountain dolomite. Its east and southwest shores expose these rocks dipping steeply to the southeast but undulating, the dip varying within a few yards from 35S.40E to 30 due S. The island in a "criche monotonese". These upturned and somewhat disturbed beds of dolomite being beveled off and glacially polished, grooved and striated. See photo. The direction of the ice movement was N.80W. Chatter marks are developed along many of the striae. The northern shore of the mainland about 1/2 mile from this island in a direction N.70E is formed of Blue mountain dolomite, dipping 10N.W.-W. This promontory is once glaciated with big garrs. The dolomite here is darker and more coarsely crystallized and in heavy beds, milk dolomite streaks and white mottling of the same.

The dip steepens to vertical in the next 200 yards and the strata in along the edge of a little core about ½ mile SSW. of the Whale Factory. At about 200 yards to the west side of this core where the rocks are again upturned, here the dolomite is in beds 2 to 6 inches thick and one layer shows small sun-cracking. The dip is 8 N. 45°W. Out-dip of beds 176-177°. At about 200 yards further the strata dip 5 S. 40 E. Here they are light dove colored dolomite in heavy beds interbedded with fintle, red and chalky beds. This is near the whale factory, and the exposure continues to the same and for about ½ nautical league. At about ¼ mile or a little less further the dip undulates from northward to southeast. The beds are light dove colored dolomite in fairly heavy beds some of which are durmerically and full of Cryptozoon. Many of the layers are sun-cracked. A few feet below the Cryptozoon, are thin bedded chalky layers full of ripple marks and sun-cracks. Below there are 3 feet of birdlike fine grained sandstone like the lower part of the Buckmantown near near Port an Port. Beyond this the strata abruptly bend up to a dip probably due to a fault which is focussed by loose material. It is probably a very small fault since similar small sandstones occur just beyond this line, and below about 8 feet of this comes once thin bedded chalky and much sun-cracked beds in 2 feet alternating with

August 18-1918. Sunday. Hawkes Bay. A cold mist, partly the colder of far mountain. Shown are all slight fairy orange. Had rock-hunt for shell-fish. Dunbar Smith Edwards and Lemire intend to go up Torrent. Rain other I will go along the south shore. The clouding up and once again before the days run. It did not rain. Are of the following shots are of Tawau Gaminage. At Camp or are pitched on the "Buttom" Heavy bedded Dolomite (see specimen). Another bed of the same kind is seen again about 1/2 mile from camp towards the south shore. At the next point a few hundred yards distance our rocks are seen. But just inside the group to the south-west on the head one heavy bedded dol, are again seen dipping at a very low angle into the bay forming its mouth. These dol. are glaciated and the others now turning the mouth of the bay. One continues in practically the same hit to the next point, a prominent one, and all are "the bottom" dol. Have some form a limestone about 2 foot thick in which the bottoms we see To be organic fruiting algae. See the specimen. As I proceed to the southerly end of this cave, which it projects deeper into the land, the above algae bottom dolomits are contain heavy bedded grit like pains saltine marbled by some prominent gravel. I could make out a thickness of about 30 foot but as once sometimes of the same nature is in the country print then may be as much as 50 foot. On the point from again almost back to the land's own on the easterly side of the cave and here the sandstone are thin bedded and interbedded with thin joints greenish chalky sandstones reflects white points. These beds represent some form of the above mentioned uncoupled area and probably near the tip. The dip of these sandstone is low probably 5 degrees and towards the mouth of the bay and Horse Island. As I proceed easterly and crossing in the section through

165 August 18-1918 Harkers Bay, South shore these then bedded sometimes with thin gms of flint to almost black shale. I go across the strike for 80 yards = about 12 feet. In the middle of this at 70 Gone I find Olenellus beds in the very thin sandstone into bedded with the dark shales. Trilobes occur in the shales along with a very rare fragment of white spongia, i.e., a Patumina. Therefore I now know that I am in the Lower Cambrian. It is then about 100 yards crossing to another point. In this interval there are lamination bedded sandstone and very few shale gones. In the latter I again saw fragments of Olenellus. At a dip of 7 deg, the thickness in 36 feet. At 40 = 21 feet. At the last mentioned point I enter into another clay core in fault of which I cannot see more than the surface ground at this side. occurs a low rocky island, the only fault exposure about 25 feet of heavy and ribbon They are reddest with some bright discoloring my eyes/163. then bedded fine grained almost white sandstone that overthrusts pinkish. On the near far side of this clay core one sees no exposures but I estimate there are here un- exposed about 60 feet of sediment. I get by estimating it in 300 feet across the dip to the other side of the core and at 10 degrees dip (has steepened since) the (= about 35 feet corrected). thickens away from it about 60 feet. Later learn that the dip is to fault information 6. At the next point mostly that crosses the headland to the core with the two classification that are a part of systematic. islands in a little about 20 feet long bedded white quartzite. The boulders are of the size of pebbles. Kelomina ferns are common to carry some clays and stones. Here is a half sandstone one can see fragments of Olenellus but they are much proportioned. On this point the shales are much cross bedded giving the appearance of undulations. Then another clay core with Carter north emptying into it. Here are small island on the strike or in thickness of strata is crossed. At the north near exposed sandstone but small Olerlithus (see specimen).

August 18, Hantles Bay, South Shore At the next point nearest to the front the headland exposes white and pink clearly marked sandstone to a thickness of about 20 feet. This is the grey headland of the southern shore of Hawtles Bay. Further the coast is a very deep bay that opposes the whole factory of the north crank, where we could along the strike of the beds and our thickness is added. The most cresting point is made up of a grey thick bed (?10) of pink quartzite followed by an equal thickness of white quartzite. One of these sandstones are much crumbled and seem now almost opposite the Whale Factory and that strata are about horizontal. I have concluded to go further out today. Almost all of the Lower Cambrian seen today consists of sandstone, nearly always rippled and more a few can be folded. The black or dark shale are probably pockets or depressions in the sandstone, this an uninteresting formation paleontologically as but two fossils are seen, and there to search for the outcrops into the west and northwest and dipping from 2 to 6 degrees, are all payments. The total thickness seen today cannot be great. My large estimates make it at about 245 feet of sandstone above the "bottom" limestone. The latter thickness seems not determined and let may not be more than 10 feet. In a straight line measured on the Admiralty Map across the strike if thickness traversed to day is one it is about 7000 feet. The dip of the strata at the camp is 2 degrees N, S, E W. This is lower than I had expected and it led are to estimate greater dips are along the section. Re-estimating: 2000 " " section at 2 degrees x 3 1/2 = 70 feet of strata 1000 " " " 4 " x 7 = 90 " 1000 " " " 5 " x 8 3/4 = 87 " " 3000 " " 2 " x 3 1/2 = 105 " " Thickness of L.

167 August 18. Hawkes Bay. East g Camp. Quartas miles for the day are as follows: " With Edwards and Lemire started at 9, 9 a.m. in a course of Torrent Burn. On the river smooth is dark blue mg., li. full of Cystogon "huttons". Dip, 2 N. 60 W. At the bend in the river after it turns east, about 1/2 mile above its mouth there is exposed a low ledge of Hurst-gray os. dips 12 S. 15 E. Oolite sandstone dipping 25 N. 60 W., just below the second ledge. Also about 30 feet of os. is exposed in a low bluff. On the opposite bank about 200 yards further in the dip is about in the same direction but at a low angle of only 10 degrees N. or. About 300 yards further along the upper end of the lake there is a low exposure of the os. for a distance of 100 yards, dipping 15 S. 60 E. The os. is well bedded and rather coarse grained, breather horned. The low exposure in mine a few continuous to the manner's 300 yards further up stream. The dip undulates somewhat dipping S. 20 E near the manner. We are slowly rising in the section having gone through perhaps 100 to 200 feet of sandstone. Here at the top it is very carty. At the falls the river tumbles over a ledge of about 25 feet of the same time, To about 200 yards below it flows in a manner rapids bounded on the N. side by a cliff of os. to a height of about 50 feet. The dip at the falls is 5 or 6 deg due W but it steepens to 35 N. 20 W. The south bank is made of different red shale weather smooth and is nearly horizontal. Near the water there are con cretions of chalk. It appears that the gorge here is curving along a fault. The os. at the falls is remarkably well bedded. Rev Dickins,

August 18-19, 18. Hanks Bay. Earth Camp. Just above the falls the dip is about 6 or 8 nearly due E. but it tends on to 5 or 6 nearly W at the falls, and swings to 30 N. 20 W., within 20 seconds below. Cross bedded ss. continues to form the north bank, and smooth creathing over the south for a distance of about 1/2 mile above the falls where we strike another later. Here the dip of the ss. is 26 N. 20 W., and is succeeded by dense fine grained light blue dol. li. Just above the mouth of the lake is exposed a low anticline with its axis S. 20 W. At the upper end of the lake about 1/4 mile above where we ate dinner, there is a low mesosome of clare or cloud dense fine grained dolomite dipping 36 N. 46 W. This lake opens into the big one that continues to the foot hills. Here have been seeing an occasional tumbled of the LC. edge wise engl. all the way up. They are more common along the north side of the big lake. Here also occur tumblers of the "fultni" layers like those at the camp. The cross bedded ss. of the falls is also exposed at various places along the north side of the lake and forms at least the lower part of the hill theorison to the north of it. Climbing up the steep timbered slope about 50 feet we come to a vertical cliff 20 feet higher. The lower 10 feet is coarsely crystalline and granular marble like li. Above it is dense dark sandy li. in lods from 1 to 1/2 inches somewhat unevenly bedded. The marble has many fragments of trilobites, and just above it occur Archaeopyga thinate?

169 August 19, 1918. Monday. Hank's Bay. South line continued. We start out at 8:10 for the south shore of Hank's Bay to where I left off. Just beyond (only) the print left off there are thin reddish gneiss sandstone with fucoids. A few hundred yards over we are again in heavy and cross- crossed pink sandstone. The same sandstone make the next stratum print. continuing to be For a mile back east the strata ^ almost horizontal, print dipping south of the north shore towards the ff [illegible] shore and now almost back towards the camp. Therefore the strata undulates in this mile and as we are facing more and more on the crossed sandstone strike mid much ^ thickness is revealed. In general the dips is from 2 to 3 degrees. In the next 1/3 mile, as the camp flies, all the ready prints are made up of very light pinkish and white, heavy folded, cross-folded and rippled quartz- its. They undulate lower and strike slightly and may be ^ not more than 20 feet of strata are seen. Then we come to a very large striking out at right angle from the land and dipping 5N to 7SW. It's a fluted somewhat liny sandstone with fucoids may this gained and flots pebble intrus, engl, some of which perforate an edge joint. These beds strike carried across the bay to the whole footery at N^ 20E. A little farther over lying and hidden in the sections there are thin folded and laminated fluted layers at least one of which has Arlides (see specimen). These layers are also cross-cracked explaining why there are intrusingle, jointedling and here. In all this grave is about 5 feet thick, and lies chiefly over the sandstone. At this place was found done a piece of li. full of Archaeocera thinae. Then 2 feet of thin folded liny sandstone with intrus, engl and then 3 feet of dense red mud clay. li, also quite intrus, the cngl. The latter look like Archaeospermum strata but saw none in flower. Then

August 19. Hawkes Bay, south shore continued. 4 fts of blue long shales followed by 14 fts of heavy hard laminated long sandstones. On one of the latter there are just the second lots of fossils. Then a deep bed of fine grained blueish arenaceous lie followed by a similar zone with Cryptogon. Then about 5 fts of laminated similar structure, followed by 15 fts more that is all that has Cryptogon, then fat once crossed semi-crystalline. Then a ridge of oxidized beds - 3 fts like before, 1/2 ft of joint shales, 1 1/2 of greenish shale, 3 fts of thin bedded arenaceous lie as before - about 9 fts topside. So this gave them some semi-oxidizing and intrusive crystalline. There may be from 10 to 20-ft more of our hard bluish to dove colored heavy headed lie. In the laminated beds we see semi-crystalline and near the top there is a thin 3 ft thick of red porous conglomerate. This takes us to the eastern side of Horse Island. As yet we have seen nowhere on the south shore any oxidized deformation. All goes in an undulatory way with dips that rarely rise to 50 or 6 degrees. Generally it is from 5 to 15 degrees. Therefore the entire thickness of L.C. along its south shore is not fresh. In a small cave, there is then an unusual infolding to the north of which appears at the foundation beneath a large calcareous line tied to the E of the Reef, once in fossiliferous Bedlmanthum dipping 20 S. 30 E. The Bedlmanthum is slightly cordiform has some intrusive crystalline and iron layers around it as the faults are common and the strata are lying at other angles lie by and chock together they are therefore hardly the basal Bedlmanthum, the line about the fault is lower than to the east. Horse Island lies to the west of the fault line and has Bedlmanthum on strike. The strike of the fault line we then returned for dinner to camp over the launched. at 1 p.m.

August 19, Harker Bay. North shore continued. In the afternoon we re-examined the north shore to make certain of the Lower Cambrian strata and their outcrop westward to the fault line. I collected fossils while Denton and Edwards traversed the north shore to near Horse Island. I am now certain that all of the strata to the east of the whole fault are Lower Cambrian, and that probably none of these strata are repeating on the south shore. The sequence of the lithology is different and the thicknesses of the various masses is also dissimilar. The fact that there is much seracactin, Cryptogams and interformula-trion corals cannot outweigh the different lithology and especially the fossils collected in this shore. The beds that have Olenellus on the south shore have their counterparts on the north shore but are not the same horizon. In all of the Cambrian strata one is impressed by the shallowness of the waters. Even the muddy and sandy lts, are either sero-cracked, knotty, pitted or have algaoid formations. When finer they are all the more certainly sero-cracked. Of dark-blue fine crystalline limestone I saw one large fossil free of Bacterellas (see specimen) but none and more seen in place. This bed was at least 6 feet thick, and its top was knotty. At our camp there are other thin and seemingly deep water lts, but as they are replete with 'button' algae they are seen to be not very deep water deposits. The great amount of sandstones and the muddy and sandy nature of all the deposits rule further herseal shallow water deposits.

August 19. Harkers Bay. North shore continued Dunbar's section and my on page 162 did not finish the section on the north shore for want of time. Today I saw here in addition to what is described there atms 120 feet of then bedded and laminated muddy li. They are irregularly bedded and in places distinctly buffy. There are also many zones of flat pettite interst, Engd. All together in the section one sees a little of a white heavy bedded quartzite. He did not go farther east as the craft seemed to expose no more rock. It is less than a half mile to the south of East River. To the above 120 feet must be added at least 214 feet of strata and 290 on page 174. (This means for the north shore 624 feet of argillaceous) described by Dunbar on pages 161-162. I mean this is not the true thickness, men, it is all that is in plain sight and was measured. Whatever the thickness all must be added to the strata of the south shore which is at least 313 feet and may be nearer 400 feet. The latter figure added to that seen along the north shore would give a thickness of at least 734 feet. Further all the strata seen up the river is at least 100 feet of sandstone but this might as much 200 feet, 60 feet of marl and 50 feet of dark sandy li. These at least 160 feet of strata seem to differ from those of both the north and south shores. Therefore we seem to have at least 884 feet of Lower Cambrian strata. See below. The Cambrian seen of Toronto river are the lowest, those of the south shore next, while those of the north shore are the youngest. On the 20th of August I concluded to take only of the Cambrian the 290 feet mentioned above. This leaves the seen L.C. thickness 944 feet. Another calculation makes it from 903-1065 mft adding the 63 feet of East River.

August 19. Hank's Bay, North-shore continued. To get the structure and sequence of the north shore into better harmony with the south shore denton and Edwards revised the forms, Denton's notes are as follows (They continue three days 160-162): "On the first part of the first cove west of Horse Island seem heavy tedded dark fluvial-pay dol. with many small circles of dol.

August 20 Tuesday. Harkers Bay, North Shore. The weather is fine and clear but the wind of yesterday has not let fall down and we cannot go either to the north or south. Duncan goes along the south shore of Harkers Bay to see what is coming Sunday and to learn if there beds are there he can on Sunday early camp at Torrent River. I remained in camp writing up notes and tracing maps. In the afternoon I go over to the whole facies of North Shore. Just to the west of the facies there are then laminated arenaceous fluvial deposits forms, these give the near horizontal & Campanian horz. a full breadth is a Cryptogon layer with the leads in the pipe form. Between one above the other, and the leads is edging conglomerate evident a new created layer dried as flat thin pellets (our specimen) out and the crushed together into the hollows between the heads of Cryptogon. There are three of these Crypt. layers is a thickness of 3 feet and all have our created layers between and interf. crypt. Associated with this zone then a series of beds of orbitis with their muddy superposed interiors, and even heads of Cryptogon. In the orbits we scattered pellets of arenaceous beds. Our forms of any kind are to be seen and certainly our large portions of these in Beckmantom, which it is not. It's better placed in the Lower Cambrian. I then focused on the 290 feet of debatable beds into the near horizontal lying limits. They show much diagenetic change, while areas being full of dolomite crystalline out-crofts and the intermediate dolomite been disturbed by the chemical changes. In many places there also small greenwork chert excursions. The strata are all very hard bedded, in fact we sees but little bedding planes. Of fossils I see none yet the bedding plans have the pseudoidal out-crofts or often seen in the Beckmantom.

177 August 20. Harkers Bay. On the shore. In general the lithology is that of the earlier Bedlamerton. There is nothing like it in the Cambria of Harkers Bay. The 290 foot next north of the main fault is lithologically linked with the Bedlamerton. It is a series of dark bedded slates mottled (like Bedlamerton) dark There are also SS. beds. and light blue-grey dolomites very fine grained. Some gives those diagnostic changes, like the northern Bedlamerton. In places there are small beds of Arl. The striking feature is however the abundance of black clays sometimes in thickest near the shale gns, 1 1/2 foot thick, in regular beds and in elongated lenses. Other gns are laminate. Dr at least one bed there are Crytofron rather in the way- bedded manner than in distinct beds. Finally however a few thin thurst scale parting from 4 to 72 inches thick, I would place these beds in the latter. To the east of this drun is then the main fault. East of it all is Leron Cambrian. See map appended to pages 171-175. Duntan saw in the "hutton" li. today a part of much of the thorax of an Olenellus. This was on the east shore of Harkers Bay near East Pier. Duntan and Edwards spent the afternoon exploring for 5 miles on the Admirelsy map it is 3 1/2 miles as the crow flies. of East Pier. They saw the Li C. ards mainly of the type shown in the south line of Harkers Bay. They noted pavments of Olenellus in the sandstone and several large loose blocks of Daltorville. Eri- dwell the latter are exceedingly common to the east of Harkers Bay,

August 26, 1918, Monday, Bonne Bay. We started out this morning on Cambria as the tide was out but it soon turned out that one could get very little. We got no crystals and one fair Olenellus head. Of Olenellus one sees many fragments but anything of value is extremely rare. One single large mass seen full of Olenellus about 3 feet long. We then started to examine the shore through the Head of East Arm and along from into East Bay we saw nothing other than Laron Cambria. In the main the strata consist of thin and thick white and pink quartzite with an occasional gore of coarse and fine conglomeratic sandstone, the main fault the remainder is a blue shale with thin sandy gore giving the schistose shales a banded character. Of limestone there is extremely little and other fossils it is in this beds. Out in the water looking back at the high Cambrian range one sees that the strata are in anticlines and synclines, northeast of camp across the head of the Arm the long mountain is an anticline while our camp lies in a syncline. We came to the northward making the high mountains just now of the water from our mile. This fact should be carefully remembered to see if there is any repetition in our section as determined 8 years ago. The L.C. strata [illegible] at the entrance to West Bay have a dip of 325, 30 E. They strike across the bay and dip a little inside of the Beach where the B.H. & down-blue-gaffing point determine mine outcrops, and same excellent they shale mountain making the peninsula lying between East and West Bays. If we fault lies between them the Beach mountain determines next directly upon the pink L.C. sandstone. There may be, however, a fault.

185 August 26. Bonnie Bay, Between the two ridges of East Arm, a fact supporting this view is the high tilted nature of the Breadman town of the Shirey East Arm. On the other hand this disturbance may be due to the cause--the injection of the past faultlets of divide and other if- near well. I am inclined to believe that the Breadmantown delimits not directly on the L.C. contains any sandstone base. In the afternoon Dentan and Edwards climbed of the high Cambrian mountain to the northwest of "Conspicuous Peak" having a height of 2050 feet, this just to the south of the north- from canonville in Mill Brook. Here the Cambrian is under- lain by the Portugue series, like a shale series of great thickness that bears Salterella like forms but with a greater apical angle, of marine fossils and therefore of considerable significance. This is a surprising discovery, and the thing should be described as Duntarilla. This note of the afternoon are as follows: "The south side of East Arm of Bonne Bay is formed of Cambrian shales which rise at a steep angle into a mountain ridge reaching a height of 2050 to 2100 feet and paralleling the shore of the bay. The ridge is divided into 2 mountains by Mill Brook which cuts across it in a deep canyon rapidly flowing southward as it emerges down from the hilllands, entering across the middle part of the Arm." Dentan then describes the Hygrograph. "Back of the Cambrian is a feet thickness of Portugue sandy shale, which are well exposed in a main stream divides that rises

August 26. Bonne Bay. 196 Inland for about one mile from the crest of the mountain we climbed, in a direction N. 30 E., paralleling Mill Creek and forming its cliffed valley wall. The Cambrian strata dip 20 S. 45 W. A thickness of not less than 400 feet of cleanly scratched white and pinkish quartz- ite forms the crest of the mountain, and below there is an additional thickness of 80 feet of interbedded sandy shale, thin bedded sandstone and quartzite. These Cambrian strata occupy a width of about 480 yards measured from the base of the drift where the steep descent begins cross the strike northwards to the contact with the Portuogies. The upper contact with the Portugesis is not exposed but a short distance beyond the lowest Cambrian quartzite seen we come upon friable, sandy, clayey gray shale dipping 50 N. 45 E., and this dip continues through a part thickness of the same kind of strata so that the Cambrium must lie upon it with a high angle of unconformity. The width across this Port. sandy shale is a mile along the edge of the cliff in a direction N. 30 E. which is equivalent to run 4800 feet across the strike (N. 45 E.). In this distance there is an almost continuous exposure and the dip remains uniform, without marking a tendency, and the lithology is fairly uniform throughout. At 20 degrees this would give a thickness of run 3700 feet of Portuogies' sandy shale. In the whole section there is no quartzite or solid sandstone layers, norli, and it could not by any similarity be a repetition of the Cambrium. "About 3/4 the distance across this axis, i.e. strike for the way to its to find my first Portuogies' fossils." See page 189 for more.

189 August 28, 1918, Wednesday. Middle Arm. Lemire called us at 12.30 A.M., because there is a quiet moonlight night. At 1 A.M. we are off for O'Rourke's camp in Middle Arm. The track progressed well and there was little sea to buck up against. Consequently we made a quick run and got to our destination in 6 1/2 hours or at 7.30 A.M. Duncan and Evans will go aft to near the head of the Arm and study the supposed Lower Cambrian section that comes in above the Portergric while I will work for fossil on the north-western shore of the Arm opposite to O'Rourke's camp. Here the strata consist of thin bedded light gray sandstone, and impure limestone interbedded with dark blue or greenish to black shales. Every now and then (in reality there are many of them) a zone of intraformational li. congl from a few inches up to 5 feet thick occurs. In them the pebbles are as a rule flat, from 1/4 inch to 1 inch or once thicker and in length up to 3 feet. There are also small well rounded li. pebbles, all are subrounded to rounded. In many cases, the matrix of the pebbles are not fully consolidated when one's together, and all of the pebbles, one of the same materials one sees in the formation, viz that they have their three long axes. With them one does share pebbles. Many of the sandstone and limestone shows own-cracking that is not very decided. These strata are much folded and marked. Interbedded with the above are thin zones of dark shales usually flint-black and these in places also have intra congl. of li. In one place for over 10 inch, li. congl. in a thickness of 3-5

In the intermediate distance the shale is seen to be considerably disturbed and crushed. Continuing the section from a rocky point. So' Heavy bedded grey quartzitic ss, dipping 60° due east. The ss, though dense and hard is small broken and disturbed. It's appearing repeated by faulting in the next two points a hundred yards or so apart. In the first of these points it dips 30° due W, and in the next 62° due W. At this last point which is a prominent outcrop th' lower 10' of the quartzite is cryptocrystic. The angle downward is broken by lenses of finer grained ss. The pebbles in the crypt. are of tour kinds, about half of them are of clear and white quartz and are well rounded to over-rounded and range in size from ½ to 1¼ inches in diameter, the average being a little larger than peas. Mr. fell. spars could be seen. On the other hand there is a relief of pebbles of rock gravel including clay sandy li. and flake li. of which some of the latter are fully of fowls. These pebbles tend to be flattened and subrounded to angular and while the average size is about ½ to ¾ inches across by ¼ thick they range up to 2 or 3 inches across. In the crypt. layers the pebbles make up nearly the whole, the material of sand being of small amount. This bed of ss. is dense and quartzitic of premium properties but scattering reddish brown on some of the surfaces. [The section is continued on page 196]
