145.2a is a seam in Mr. Furnsworth's yard, containing Chonetes novascotiensis Almd. Tentaculites Comm. Leporidita common. Beyrichia. 145.2a^1 is a seam 5 or 6 inches higher containing: Retzia Almd. Tentaculites almd. Crinoid joints almd. Beyrichia common. 145.2 & B includes some fossils from the splinter shale in the knoll on Mr. Rogers' meadow back of the burned house, north residence. These fossils, 50-60 ft. above the creek include chiefly some Beyrichia, & small Coratocaris Comm. 1/2 of Leptenospiis is y. rare. large Leporidita (common in seam) Saturday, July 27, 1907. (from 145) Continuing the section downward in Furnsworth's Slooors have we find that the columnar Beyrichia for a underlying 4 feet of laked shale containing a found of large reticoid gastropoda ? Grammysia cingulata the same as 5.3.8 &. Below these 4 feet of laked shale occur about 15 feet of semi-columnar, much shattered dark gray flag slate fiss. = 112'. This bedlets normally appears was- nut in much formed but in places four lines or amygdulite lines are clearly traceable parallel to the beddingplanes of the overlying underlying sediment. This lava also contains many scattered oval amygdaloids of the size & shape of bean eggs, over a few inches below the top of 1129 occur an arkose or volcanic ash sand varying in thick- ess from 5 inches to 20 feet, and in places to nothing. The rock 1130 consists of angular and partially round-ed fragments of the age of pipe or little smelzer of pink & red tuffal foldspeps and bryotes. The lava 1129 is underlain by 2 feet of sediments which in places but not of thin slabs chales only slightly break. Part of the sediment more tightly lakes especially the upper half, and in a couple of seams appears a foot thick appears rhysolitic. Such a specimen is 1131. These 2 feet of sediments are very fossiliferous in seams which for as much as an inch in thickness we rendered calcereous by the contained beds of shells, the pred bulk being gastropoda Bellerophon carinata (acutus), Belleroph. tritubatus, Murchisonia, Helixys Plate-, schismus, Catelostomum, and a few ?Grammysia cingulata. These fossils are 5.3.8 C strike N. 25°W. dip 32°N. 65°E 5.3.8 & includes a couple feet carrene seams near the top contain- ing Large Larnellibranchia. Grammysia cingulata Grammysioidea sp Cypricardites 2 sp and Gastropoda Platyschismia Bellerophon tritubatus (acutus) murchisonia sp Helopella sp and Spirobris on Larnellibranchia-dant.
