Base Black Shale, 632. Thursday - cant Section at William Richards house, North of mouth of Forbush creek, in NE side of river, from top of section Whitfieldia layer. See opposite page this book, 50 ft. The readings all with hand level. The Whitfieldia layer is 50ft above mouth of Forbush creek. Corrected triangmetric reading. About \1/4 mile eastward up the creek a small stream comes in from the north. Here there are 15ft, 6 in. of limestone below the Black Shale. This is indicated in the section on opposite page. A 3 in layer of sandstone seems to occur just beneath the Black shale, but only a trace is seen. The crinoidal layer occurs 21 in. below the Black shale. Black Shale 3 in.

Base Black Shale, Little Cub Creek. 591 Friday, 21 July '99. 10. View of Clinton rock exposure. Just below the mouth of Little Cub Creek. Dip N 68 E, in this long exposure nearest the mouth of the creek. Dip N 22 E near west end of exposure. D mr stream in West bank the dip is southwest; precise direction of dip is unknown. Section of view just below Little Cub Creek. Instead of following section take one below. 19 ft. of blue siliceous limestone, weathering rusty brown. 19 ft + Madison bed, clayey calcareous rock, very much like beds in Marlow Co., &c. Section of view just below Little Cub Creek, Black Shale 7 ft probably all greenish clayey shale 2 ft of layered limestone layers over 2 ft 6 in. of green clayey shale 3 ft 4 in. Ozogrod limestone. 15 ft 8 in. Clinton limestone 19 ft. Madison. Notes on above section. The entire thickness of continuous limestone layers is 19 ft, but the base of layer with many large round beads and Multifolia cylindrica 3 ft 4 in below the top, hence the sum of top section considered Ozogrod. On this lies clay shale, thin layered limestone; there are well exposed at mouth of Little Cub Creek. Above this there is less continuous exposure; greenish clay shale is exposed at various levels, and 1 foot of this clay shale occurs just beneath the black shale as indicated in the section just described. This makes the thickness of the total Ozogrod about 17 feet. Clinton 15 feet 8 in. Madison 19 feet. Dip seems to continue southwest as far as Norman's Landing, About 2 mile east of Norman's Landing the layer marked I seems to occur at water's edge, at any rate it is the dark blue clayey Marbury shale, and over it lies a thin limestone ledge with good Spirifers &c, and above this plenty of additional clayey shale. Beyond all question, there is no Lower Silurian, Clinton, Ozogrod Black Shale here, nor is there any grey layer Marbury. This indicates the existence of an anticlinal axis along the south rim edge of the river course. Rained nearly all day.

Saturday, 22 July. Morris Landing, 1/2 mi. above Nor- man's Landing. [illegible] A comparison of the next two notes indi- cates a fall of layer G of 88 1/2 ft. toward E in going 1 3/4 miles. Base of Black Shale 508.5 About 4 mile E Morris Landing towards mouth of Falls Creek, the layer G is found at water's edge. This is about 1 3/4 mile from next section. Base Black Shale 597. Section west of Morris's Landing, just E of sharp bend where Comber- land river turns N, near Leadville, section above this not measured. Abundant shale. 4 ft 9 in. crystalline limestone with chert. 27 1/2 ft. greenish sandy shale with phosphatic nodules at base. Black Shale. 39 ft with nod- nules at top. Contact with Mad-i-son apparently confirmed. 2 2 ft. of Madison bed a-one grained bed. Ripple marks in Madison N 10 E. Saturday cont. Just above Thomas Branch on E side of river is Madison bed dipping N 60 W. The Madison bed here is a thin bedded sandy limestone, the thin beds however hang together must lying separated by crazy courses. The thin bedding shows up beautifully in cross-section. Ripple marks 1 foot below Black Shale. N 49 W. Black Shale rests on Madison bed directly. No lizzard or Clinton. Ripple marks strike in various directions in upper beds of the Madison beds. These direc- tions change for sound to make it with difficulty to record them. Just below the mouth of Thomas Branch, The Madison beds rise going north west and still further south-west they dip north westward again. All the dips near Thom-as Branch are merely dips of strikes as seen at their exposed edges along the river bank which here runs about N 30 W. North west of Thomas Branch, about 1/2 mile the top of the Black shale with caracteristic nodules is found 99 X feet above river, estimating the thick- ess of the Black Shale at 39 ft. the base of the Black Shale is found at 60 ft. above water edge. The massive Madison beds are found at the base of the section at the mouth of a creek. West of the creek the highest part of the whirling thin- bedded Madison is found at 25 feet above the water's edge. The missing part of the section is unknown. Stanley

[Heterospongia (See below)] be the remainder of the Madis- son section but there is room to rough for Clinton: Wavely shale Black Shale, 35 feet measured, 39 ft. estimated. Unknown. Thin bedded Madison, Heavy Madison, X Bryozans. About 1/2 mile north westward of last section is the second creek coming in from NE side of river, since pass- sing Thomas Creek. Here some large bryozans were found near lower part of massive Madison beds, and t-here we sent to G.O. Ulrich. Mr. Joseph Morrow, Rankin, Wayne Cr, was present on this trip. See section above to which this fact was added. bryozans = Heterospongia subramosa, Ulrich. Rained nearly all day. Tried to buy a wheel for our boat. Anna went back with us. Rock rise on going west to top of anticlinal. See next days work! They evidently has been a rise of 60 feet for the base of the Black Shale from Thomas branch to the creek just E. of the anticline. Base Black Shale 572, Sunday July 23:99. Anticline near middle part of course of river where it flows westward, a short distance further west it begins to flow southward. The for- miferous beds below the Madison are brought up by the anticline. The axis of the anticline is a short dis- tance east of the main bend of the river, changing from a northerly to a southerly course. At the axis of the anticline the section as far up as the massive Madison beds is exposed. Up the first stream going westward and then up a small branch coming in from the north, The section is continued up to The Black Shale. The combined section is given below: Base Black Shale 625 42 ft. Barometric. Prof. Miller Black Shale. 32 ft. Madison beds, Upper part thin bedded 9 feet heavy 4 ft. Transition beds to Madison 17 feet of Richmond beds.

Sunday. Continuation of section described in preceding page described by Prof. Miller. Heights are barometric. Conglomerate gravel Purins clerty fragments Shale Grey crystalline limestone Criminal. Clerty shaly limestone. Dark chert or flint. Sandy shale, more irregular and calcareous at top. x Nodular layer Black shale. Thin bedded Madison Thick bedded Mad Richmond beds 22 10 40 brams. 17 Sunday. Certhia biforata occurs in the thick- bedded Madison bed from 3 feet above the base to 7 ft above the base. It is rare but can be found. 14 specimens were found between the anticlinal and the place called the ripple on the map. The branching byrgans are found from 5 feet above the same to 7ft 10 inches above the same, 15 specimens found. The globular byrgans are found from 5.2 feet to 6.2 feet above the base of the heavy Madison beds. Considering the fact that the heavy Madison beds are 9 ft 2 inches thick time, it will be seen that five Siluria fossils are found through its entire thickness. Moreover the thickbedded Madison is lithologically the same as the overlying thin bedded Madison, but the thin layers hang together and therefore have a total massive effect and break off in larger masses from the cliffs. Hence the beds are often 1 inch thick while the beds of the thin bedded Madison are often only ½ inch thick. Note the absence of the 26 inch blue limestone layer (R) from above the Madison. This denotes that the Black Shale does not lie on the top of the Madison, one of the Madison having been removed by erosion. The Richmond beds contain chiefly Certhia biforata, and hyrgans. Certhia occidentalis is rather uncommon.

Bare Black Shale 600 A short distance below Breasy Shoal on the west bank of the river is the, following section: Black shale 2 1/2 in Sandy layer. Olinphlites led Dry. Miller Thin bedded 28 ft thin {Madison beds 38 ft. bedded Layer with branching Bryozoa and heavy Blickleaded 16 ft, About 5 1/2 feet below the top of the heavy Madison beds is a layer with more limestone characters, containing quite a number of branching Bryo- zooas. Typical Madison ortho is found below this Bryozoon layer. Orthus bifrons is found less than 2 1/2 feet below the top of the heavy Madison beds, Tuesday July 25 '99, BL Shale 629/19 About half way between Breasy creek and Belk Island, on the west slope, the following section is found: Black shale. 3' in layer sandstone, plurphatic Milleri Orthus bifrons both residents seen at my trip. 68 ft Richmond beds. The lower 20 feet are very fossilifer- ous, and don't get anywhere, but the alternates to. From 1-3 feet above the base of the Black shale a greenish clay shaly intermixes. Black shale below. While the number of fossils decreases from and to the top of the section and the lime becomes more clayey, there are nevertheless less plenty of fossils here. Along the bank north east of Belk Island very fossiliferous thin limestone with very marked layers, one exposed for a long distance dipping west. At the southern end of the island, the east bank of the river shows the came strata dipping east. About 1/4 mile beyond Belk island on the east bank of the river, the arches dip sweet almost as far as Belk Island. Farther southeast down the stream, there seems to be a southwest dip again. All of these dips are well marked but gentle.

Tuesday July 25 '99. About 1/4 mile beyond Belk Island, on the east bank of the river, where the high cliffs begin; the following section is formed: Black shale apparently rests directly upon Ricken and beds. White layer possibly about, not seen. mud clays, less fossiliferous. chiefly Bryozoons massive very fossiliferous, 6 ft above river. Salechnus & Tetradinium abundant. [illegible] the upper 50 feet of the Ricken and beds mud clays, and less fossiliferous nonetheless carry Orthus lividatus Orthus occidens, also enough to make possible to find these fossils at all 2 feet of rock below these 50 are pure white in appearance and are char- acterized by containing chiefly oolithic Bryozoons. Lower 17 3/4 feet are very fossilifer- ous Owing to the facts that there is an amount of regular limestone interrupted by this clay partings, and as we have the appearance of the rocks at Hopping and Hull + Can tain some fauna. At the bottom of this section Salechnus & Tetradinium fossiliferous mud clays 20 feet thick. Tuesday cont. At the bend of a river about 1/2 beyond Belk Island I took the following photographs. 5. A little further down the river. 6, 7. One at time exposure ... 8. A little farther up the river. 9. One at time exposure. 10. 11. Still further up the river. All of these views were taken within 300 feet of me another. The focal notes will enable me to re- produce the elements of the sections in three photographs!

Tuesday. At this place about 2 feet of greenish shale can be seen me only at the base of the Black shale. Only about 1/2 foot of black shale intervenes between the greenish phase of the Black shale and its base. This greenish phase of the Black Shale was first noticed half way between Greasy creek & Belle Island, see notes 3 pages before this. About south of the western end of Belle Island, on the next turn of the river, where it flows west, on the north bank of the river, the rocks dip east. About 10 feet of very sandy limestone one with small bed cross bedding are exposed. Towards the top trigram remains, and a few cuttings of crinoidals & O. bips data came in. About 10 feet of frail shaly limestones overlie the sandy beds and about 2 1/2 miles above Romana the rocks dip west again and about 2 miles above Romana, the Tetradians and Scutichia beds are found about 10 feet above the frailling beds last mentioned. All of these measurements are guesses but the important fact is the existence of a rough crossbedded beds at one great distance below the shale chips beds of the delta on my mile below Belle Island. Wednesday July 26 '99, B.E. Shale 650. Just below Medina branch, at the beginning of the high cliff exposure on the north side of the river, 2 miles above Romana, the following sections seem: 8 1/2 feet thin shales, dark. 14ft massive limestone weathering brown 45 ft dark shales = limestm shales. 5 ft less shaly. At top with gardes - 65 ft shale at me, and soft of shaly hard and dark lime st me.

X The 27th, July 27 '99. Black Shale 681. About half way between Indian Creek and Long Bottom Island, a little near to Indian Creek a short distance from reaching the strung bed in the right, the fol- dowing section is shown. 36 ft. Black Shale D, 6ft of binnish rock in face of B.E.D. 48 1/2, Madison beds. More thin C, lodded below and some layers more in massive layers 3-12 in. thick near top, 16 1/2 ft. soft shales with about-B, dunt fossils at base. 91 32 3/4 ft. of massive clay stone with limestone in irregularly defined horizontal patches (early madison?) 74 3/4 A 42 1/2 ft. of bedded limestone with clay partings, the latter then still hard forming a clay rock in which the limestone occurs as layers. Rich mud A. Portelno, Caliprato, A. occidentalis Lamellibranchia, Murchisonia, Bucania. B. Section above face not exposed. C. This is the appearance the Madr- sion bed should have of this bed turned to a gentle plane limestone. The lime- stone is very dense, very fine grained of medium then rather light blue color, when weathered it shows that it is made up of very thin bedded layers. X Thursday hanging together, it is practically impossible to see but I found in it one specimen of Lingula? sps. Does this indicate Lower Upper Silurian age. at trip = The occurrence of quite typical Mad- ison beds on the clayey beds with few regular limestone layers, which I have suspected to be Madison further up the river at a number of points is very interesting. Does this mean that the Madison does not become fossiliferous when folded horizontally in an exposure or exposure? at face of Black Shale is a brown- ish sandy appearing rock which when freshly fractured appears as though it might be the base of the Black Shale here, corresponding to the greenish mure clayey beds seen in the range of the Black shale in the section half way between Greasy Creek + Belk Island. See 8th page preceding this. The very thin bedding shown by this binnish rock is especially characteristic, and suggests relationship to a shaly rock, and as I suppose from previous sections, to the base of the Black Shale. See 4th page following. 7

Thursday July 27. '99 cont. The section first described is a little east of the centre of a long low flat syncline. In my sight distance below Indian Creek strata, the rocks dip westward, at first rapidly and then more slowly. Then for any distance they are nearly flat. A short distance above Longbottom Island the same rocks dip quite strongly southward a little east of south. At the lower end of Longbottom Island and the rocks dip northward a northeast. Half way between Longbottom Island and Little Indian Creek the rocks dip northeast again, the dip in the opposite direction between those two locations was not very marked. Near the northeast end of the high cliffs extending on the west bank of the river from Longbottom Island, northwards, a path leads up to a house and thence around leads back of the highest ridge up the river, to a school house which may be seen on top of the high ridge, in coming down the river. Half way between the house first mentioned and the school house, is a log cabin opposite which is a little gully in which the following section was found; Base Black Shale 656. See 2nd page beyond for continuation of upper part of this section. Black shale, 2 1/2 ft. Rather coarse dark shales D 3 ft. Greenish layers in black shale. Black Shale 4 inches. Residual phosphatic layer .4 in. 12-ft, 9 in. Thin bedded Madison 11 ft. heavy Madison beds, 83 ft. not observed. D These shales look a great deal like some of the dark Wavely shale. They are irregularly fractured, and do not break up into the thin fissile shales characteristic of the residual Black Shale.

From river bank the base of Black Shales cliff is seen to weather + form a sort of soil. E. Residual layer, hardly 2 inches more like SS. C. This at me corresponds to the 1st case in which I found Siphonopsis. It is very finy and dense, and contains very small fossils which I do not recognize. Among these fossils are gastropods. This at me corresponds lithologically best with the gastropod layer, near Madison, Indiana. D. Judging from amount exposed vertical sided cliff when it could not be measured, 1 to the close is about 12 ft. This number is partly secured from a previous section & top preceding,
Page 22
A. Upper 4 feet of the 20 ft of limestone consist of dense blue limestone, in 4 layers. The top layer is very fossiliferous and contains Arthoceras Murchison ia, Oterinea, Modiolopsis? Cellus occidentalis, + a smaller Modiopsis? I collected quite a number of fossils here. (For fossils see 2d page preceding this) The lower 16 feet also consist of limestone but it is evidently a thin- banded limestone, though the thin bands hang together so as to form quite a firm stone. These thin banded limestone weathers more readily than the limestone courses which do not show any bedding. The upper limestone beds slum in the weathered surface, gaesterford and Arthoceras very much in the same style as does the gaesterford layer along the Ohio river country near Madison Indiana and thence south westward. They correspond to the massive beds at Rock House, apparently, by a virtue these beds. B. 12 1/2 feet of clayey rock, weather- ing into Clay shale. The basal part formed hard, rather white as look- ing, then courses. C. 7 inches of rather solid lime- stone. D. 3 feet of clayey Mud, like rock massive looking, weathering into a soft clayey rock. E. At the base of the Black Shale, the lower 3 feet weather more readily. The total measured section up to the nodular layer gives in 30 feet for the thickness of the Black Shale. Perhaps the nodular layer has fallen down the hill side a little bit of this I have not evidence. F. The lower part of the section was secured from the end nearest Willis's Creek bluffs. The 14 feet of thin bedded clay limestone there underlie 3 1/2 feet of heavy limestones. These limestones I assume to be the lower layers of the 20 feet of limestone slum in the Furler's Landing section. According to this interpretation, we have here at least 21 1/2 feet of rock above the rock shun at Rock House. In that case the thin banded limestone which has the massive appearance and which evidently belong above the thin bedded May- or contains clust. Unfortunately, I do not remember whether the limestone bed with clust actually was at the base of the 20 ft. of lime- stone at Furler's Landing. I am not certain.

Sunday July 30, '79. Set C 2. View of synclinal just below mouth of Rennix Creek. There were formerly oil wells here. The Big Dancer can well was sunk into the bed of this creek, A short distance above Bakerstown Landing, where a stream of water runs out the cliff sides into a small stream, towards the hill summit, a considerable number of limestone payments, peatly cherty, are found, and contain the same fossils as those found at Fowler's Land- ing. (For fossils see 6th page preceding.) At Bakerstown Landing, up the cliff just above the Landing, the lower shaly Madison rocks are well ex- prired near the upper part of the cliff section which is free from limestone. The top part of the cliff section free from rocks, formed by about 4 feet of lime- stone with chert nodules (Rock House) beneath are quite a number of feet of thin- bedded limestones, excellently shaly in places. Above this occurs several feet (4?) of fossiliferous limestones con-taining the same fossils as those found at Fowler's Landing. Above an about 10-12 feet of thin bedded rock, in which are thin siliceous curious beds, like siliceous layers Lyellia until examined. The Black shale probably once oc-curred immediately above this, Just above the mouth of Rennix Creek the following section is shown: Base Black Shale 620? Black Shale? 5 6½ feet. thin bedded limestones + clayey limestone. 1½ ft. heavy limestone, Lancellibrand 2 ft. of dark shaly limestone, a clay, B 18 ft. 9 in. thin bedded limestone + shale A 5 ft. Rock House limestone with chert nod. 14 ft. clayey shale, thin layers. A. Main part of section consists chiefly of thin bedded clayey shales, but lower part and upper part of section con-sists of thin bedded limestone, easily breaking up along the bedding. The upper ½ feet of these rocks partially formed part of the 4 feet of limestone inclu-ded in the upper 4 feet of at one sepa-rated from the 20 feet of limestone at Fowler's Landing under the name of the fossiliferous beds. B. With Orthis occidentalis, Amhomy-chia radiata, Pterinea obliquata. C. This limestone is very fine grained- it still belongs to first limestone beds. Laureasat Fowler's Land. ½x

Just below Renix Creek is a well marked syncline which was plotted. graphed. A little farther down is a very strongly marked anticline. At Renix creek the Jessen or Madison beds do not appear at all. The line up riverver at the anticline farther down the river, at Renix creek there are 56 feet of rock exposed above the fossiliferous limestone beds. Does this mean that in the Renix Creek syncline a greater thickness of Madison beds was preserved than for quite a dis- tance up the river. At Rock House the Rock House cherty bed is preserved, at Farley's Landing, the Farley's landing fossiliferous limestone, and at Renix creek, the Renix's creek upper Madison beds. This indicate a thickening of the beds in series in this direction. Set 6 8) Below Alexander Bar, just be- fore reaching the bend of the river, 9) 10) There is a strong dip of the arches 11) 12) and stream then they are nearly level for a long distance.

Tuesday Aug. 1, '99. Packed up, leaving boat in charge of mill owner. Paid $25.35 as my share of expenses. Wednesday Aug. 2, '99. Work stage, Burkesville to Glasgow. Good road as far as Willor Shade. The Lower Silurian is exposed as far as Willor Shade, just beyond Miller Shade the Black shale over lies it. The elevation of the face of the Black Shale = 133ft. corrected barometric measurement below the elevation of the post office, Court house square, at Glasgow. The elevation of the depot is probably a little above that of the P.O. but the difference is surprised out to exceed 10-15 feet. At Marantine there is a fossiliferous layer in the same Silurian only 11 feet below the base of the Black shale. A fine piece of silicified wood was shown me as coming from thence. Glasgow = 780.

Friday Aug. 4 '99. Went to Nashville. Prof. Safford had gone to Monteagle, a summer resort in SE part of Bluegrass region. Mr. Killebrew was strangely ignorant of the distribution of the sedimentary series of the state. Phosphatic plates had recently been found in Tennessee at the base of the Black Shale and in the Nashville series, 30-70 feet above the top of the Trenton.

This is not disproved by the 8 ft. banded Madison which evidently, is only the upper part of the series below. Near the middle it contains limestone, but the fossils can not be readily recognized, being brand mix fragments, yet well preserved. The underlying this layer is the top of the 40 foot series, containing: Strophomena thin alternata, crummi in abrupt. Septuena zonicea, Cyclammina, canellibranchus, including byri- grains.

Friday Aug 11 '99. D. This should be the Waldron Shale... The lower 1 3/4 ft, consist of shaly limestone with fossils. A- nery thin the large Pynch mella Stricklandi. Above this lie 6 ft. of Clay with num- erous specimens of the flat limons. This layer is an one fossiliferous east of Pegram 1/2 miles. See parts next page, E. This is a very fine building rock and should be equivalent to the Simisville limestone, stratigraphi- cally. Phosphate rock abound in Lingulae, Mr Finbee + Blee's Hollow the following section, found. Brown phosphatic rock 3 in, at base/ 6 in of fissile Black Shale / 9 inches of dark phos- phate rock with Lingulae. Plenty of Black Shale with earthy layers intercalated at various levels, A cherty bed about 1 foot thick occurs about 10 feet from base of Waverly. The Black Shale presently goes un- der cover a short distance W. of the bridge, it dips strongly S.W. as to get to the water's edge, a quarter of mile south of the bridge. Coming to the same place the lower limignus are quickly brought up in spring E, Saturday Aug 12, '99. [12] About 1/2 miles E of Pegram Sta. on N. side of RR is bridge of S arm Walker, A short distance West of same a road leads SW through the woods to Harpeth river. Another road runs along the north bank of this river, and following this road Eastward, the following section is found at the end of the cliffs, near the point where the road leaves both the cliffs and the river.

Sat. C continued. A quarter of a mile S. of the last section, on the south west side of the river is the house of Bell Robinson. Near the spring NE of the house the following section is exposed: 18½ ft. Limestone Pilocrinus gemmy myfinis are rare at base. 7½ feet clay + clay I. 22½ feet thin bedded limestone A shut abundant near river's edge A. In the shirty beds at the rivers edge, Favosites is found, rather common. 14½ feet above the road is Halysite forming a layer about 4 in thick and several yards in extent. 7½ feet about the river an Olear spf. about the size + form of divers Olearium Acutiformis found, glabella. this clay does not seem to extend to the bottom clay, clays only for about 3 feet and the part is a rotten claygy while it weathers dry. So as to connect the clay limestone to form cliffs of no value as a datum line this layer is there fore not to be used as Clinton. At least But it seems 12 C cut thinnest ones, follow the clay sides in the hollow N of the RR. near the bridge W of Pegram, C. These are the clayey limestone at the bridge W of Pegram. They can be same good limestone E of Pegram. Combining the two sections 1½ miles E of Pegram, we get: Black Shale Platolate layer. 28 ft. Louisville l. 12½ ft. Waldron shale 29½ ft. Samuel l. see Newsam section. 7½ ft clay + clay I. Olearis Halysites layer. Favosites We also find that the 2 sections supplement one another. The Squel limestone is either 72 ft + thick, with the base not yet found or the Samuel is about 42 feet thick with the beds under the clayey layer as Clinton. In last case the bottom beds have practically all appeared.

Corresponds to the crinoidal rock found at base of Black shale W.J Lafayette Macon Co. Cornif- erous? No trace of Ostracata. Contains little pebbles. C. This rock has a very Devonian aspect. It has a very white color and is coarsegrained. It resem-bles fine grained undivided Niagaran. It contains Haptema- nerid shells, rather abundant, signing Devonian appearance. D. Near base is layer with small form of Pterocrinus, half the size of P. semisiformis. C. The Devonian loding rock seems to run into the underlying Niagara rock, without any great break. E. This at me is quarried at summer- cus quarries near Newsom. F. From this section it will be noticed that a considerable thickness of Cherty beds lie at the base of the Lurmel limestone. The best beds for quarries lie at the top after at Clermont, Ky. In the Bell Robinson section only the top 1 of three cherty beds are seen.

LS 23' 10" Massive Edge LS 5' Thin bedded SS. 2' Bridge 700 [illegible] there is a strong dip to the eastward here or the dropping out of the layers above the Clinton and below the Black Shale in exposing the stream accounts for the lower elevation of its formations in the east side. I could not certainly identify the formations immediately following the shale on the west side, as could find no fossils.

The Black Shale rests immediately on micaceous Clinton on this side. Some peculiar crinoid bottoms are abundant, and the lithological characters are exactly like the rocks at the mouth of Cub Creek. I have leveled 16 ft. 1, three layers. I found this Fishing Creek section very interesting and would like very much to revisit the locality again sometime in company with you. It is 5 miles from Somerset. Section opposite oil well at Cloyd's Landing about 9 miles below Burlesville, Cumberland Co. Ky. well burned 10 days before the fire was put out and flow was gotten under control. Well starts in fossiliferous Hudson, about 145 feet below base of the Shale; and gets to oil at a depth of 440-450 feet below the surface - making the oil horizon for this section about 600 feet below the top of the Hudson, where the full Camp bellment of Hudson beds are present. I suspect a thin- ning out of the Hudson beds southward from here, as the section at the Middle Hudson (Barred SS) at Martinsburg within 2 miles of the Tenn. line, would seem to indicate.
