Perry Pebbles in the conglomerate (all from Les K.) 1021. A soft black coal fragment overlying gray shale. The black coal- 43 like color may be superficially due to manganese stains. A few similar pebbles observed; all smaller, more or less inch thick. 1022. Gray shale occurring as a rounded, water-worn pebble in the Perry. 1023. Dark pelite porphyry with vitrified glassy spherulites. Similar pebbles are -quite abundant, though less so than the granite, quartz or pink felsite. 1024. Pink granite. Very silicant. 1025. Dark redish-buff grained felsite rock. 1026. A stratified red sandstone like fragment occurring as a delta. Perry 1027. An angular mass of plainly lower Perry rock occurring as a pebble in the sky 1028. Miscellaneous assortment of pebbles. 1029. Large examples of Perry conglomerate (pebbles smaller than usual). Section continued. "E" Severed gap, 290-505 ft forming side hill. "f:" 535-536. sandstone & conglomerate in a low 5-foot ledge; Strike N.13° E. Dip to meet, amount uncertain. "g" Scattered ostracop in the sides & in the rounded mass & All these ledges strike N. 10°-12° E. and dip to the west the amount of also unknown but in places apparently about 30°. (g) A two foot ledge of very coarse sandstone. (h.) at 675-695. a 4ft. ledge of slabby sandstone including fine pebbles in a very coarse sandstone. Dip 24° W. (i) A series of about 10 ft. of very coarse grained sandstone (very coarse grained) until hardly any pebbles at all. Strike N.10° E. Dip 26° W. These less ostracop in massively 100 yds. N.W. of first ledge. CARLOW ISLAND. June 19, 1907 348 In the afternoon a trip was made to Carlow Island. The shale were observed in the southwest grid of the island striking N.55° E and dipping 23° northeasterly. First north of a large trap dike in gray shales right at stratified land, which makes up the whole advents of the island. over some seams of modiolopsis and lamellibranchia and Lingula. these fossils are 3.43.6 a. The staly beds of the southwestern part of Carlow Island are abundantly wave & ripple-marked, and rain prints are very common. A porphyry dike cuts across the shales and illustrates first contact planes. 1033 is the normal porphyry, 1 yd from the contact. 1034 is the contact phase of this porphyry, 1 foot from the contact. Just above thru porphyry dike occur shells containing both Strickleya crassa & rain prints on the same surface. Some shales occur in a little carhood but near the south end of the island X-anton (not collected) the same lamellibranchia as 3.43.6 a. (Dike cut is not the same as 3.43.6 I, p.75 which is at the middle of the island).
