14 Block form seams containing all exposures lenticular seams full of Operculites at "28" off," appear to follow an exposure of minor contact on the strike, and large clumps of tuff are included in the base of the "tuffs" as met. See thin splintering shales, near in the extreme corner of the one in the left hand side striking N.15°W and the strike running around to N. 30°W on the course of 20 paces northward, between them, crossing the road at the bridge we find the little creek to run nearly along the line of outcrop of the Shales which are exposed striking N.40°W and dipping 15° N.E. On the east side of the E boundary of 1957-9 and 5E boundary of 1956 shales appear striking N.58°W and dipping N.70°L at a low angle. The Shales appear on the northerly side of this line displaying few fossil indications and are overlain by the tuff. Fossils seen in several seams in the shales and valves Chonetes (common), Camarotoechia (common), Tentaculites, Thelodus, Reyrichia, Actinoptarella, Grammysa sinuata? Mucrites, ?Horismen danbyi, Crinoid sps., Heliosiphon sp. = 1956 A These shales are overlain by a granular tuff breccia (whole aluminous of pfeppar). Immediately under the tuff where the Shales are naturally crumpled and rolled and a few traces of baste appear to be included at the base of the tuff breccia: very few abulite fragments are included in the lower half which quite the rock the appearance of the grained tuff shale geography. In the upper tuff, especially the upper foot there at some stratification the beds strike N 35°W and dip 26° N.E. the strike from these beds up to a slight deflection where the hill is replaced to the S.W. with thin feet of Shale perfectly laminated Chonetes seem now to be absent as met south, Thelodus, Reyrichia. = 1956 B (not collected) The shales here strike N. 35°W and dip 27° E. There is another found alone extending N. 27°E and bringing the tuff. Shale there appear in running to the deflection indicated within a small depth apparently fault extends N.E. The hills are steep sided S.W. inland as well as at slope so that it is fairly certain also the displacement of the clear side makes it, hard to South side road, turning S.W. toward Dr Col some gray splinter Shale crop out in the road about 175 ft from the Seymourapam Road. Fossils found in these shales = 1959 A. Selwynia (common) Chonetes sps. common Constrictella sps. Horismenille rare. 251.A, 15 northeast of Small Island in a little creese into all north edge of 2-57/1 seems to be Ledge, if any fossiliferous shale, with A striking N.40°W and dipping N.E. at 10°? east of North and dipping south of East, and continuing Linguula (large, fairly striate, common = ? rare smaller, found in glass). Lingula (small, elliptical), occasional Operculides (?) sps (lenticular) occasional Camarotoechia (? Retzia).

The median paleo Scales strike N. 27°W x slope at the N.E. and near the Ave into 2512 the shales strike N. 35°W and dip N.E. at about 150 They contain in the lower half Leporidra (common), Linguicostellata grammysa (rare) = 2512 A, in this upper half also containing a seam with Beyrichia (abundant) Loperidra (common). Lingula rare. A Platyochisma was not described on specimen and not in place.
