28 Quadrille Ruled Form. Patented 1906. John C. Moore Corporation, Rochester, N. Y. June 13, 1907. Shales may be observed along the south west shore of the island striking N.55 east and dipping 23 degrees N.W. Just north of a little trap dike which cuts the gray shales and occasional quartz- itic bands that make up the sediments of the island occur some seams of Mod- iolonsoid lamellibranchs and Lingula cornea. These fossils are 3/43.6:A. The shaly beds of the southwestern part of Carlow Island are abundantly wave- and ripple-marked, and rain prints are very common. A diabase porphyry dike cuts across the sediments and shows good contact variations. 1033 is the normal por- phyry four feet from the contact. 1074 is the contact phase, a foot from the contact. Just above this diabase porphyry dike occur shales containing both sun- shrinkage cracks and rain prints on the same surface. Some shales occur in a little railroad cut near the south end of the island, and contain the same lamell- branchs (not collected) as 3.43.6:A. (This cut should not be confused with the fossiliferous rr.cut near the cen- tre of the island, containing 3.43.6.B copied from Note Book 1, p. 43.
