3. 34. 6. This gabbro is very coarse and in word of the mass strongly amygdaloidal. It is a narrow by a little patch of very much baked shale about 5 or 6 feet thick. This baked shale is filled throughout with large unstratified & light colored laminated bands nearly 2 inches wide generally, and with few stratae of much the same like footpath. This famous 6.33-4a occurs foot due west of the south end of Weyors Island in the shale along right side. The famous is "p", presently the same as the Clearfield shed series, also 6. 34. 6 a. The shale here is only a gabbro dome and appear to have general dips. Three beds with very large lamellabranche reappear further north along the shore a little north of west of the north end of Kodgers Island. The shale here appear to be over 50 feet thick as much baked & brecciated in places and are broken up into blocks of a couple of rods. Except the different streaks striking & dipping in different directions (more horizontal). The cause of the brecking appears to be a large gabbro mass forming the country a few yards west of the shore. This is also of sediment washed b. This patch of sed- imment may be traced somewhat eastly across the road where some good laminabranche may be found in the west side of road just on the right side a cottage f. This patch is love distinctly too to flank the top of a dome of gabbro, and the gable marked "f" (sketch map) similar flanks a dome of gabbro. The are by sediment includ d also flanks a dome of gabbro on the west and dips under shale on the east. "d" strikes N. 20° W. and dips 40° E 20° N. It con- tains some lamellabranche (top) and 6.349 ostrodote too good preserved to identify, all by themselves but apparently the same as 6. 34-3a, The beds are shale & calc. core again. Wednesday. July 10, 1907 North Lubec Ferry northward. From the ferry wharf northward the gabbro skirts the entire shore as far as Reynolds Cove except for a small area of extremely baked sediment not more than a couple of feet thick merging with few dome of gabbro giving just at 1/4 south of the southern point in rather 6.34.3. The twenty track of the shore along this stretch as far as Reynolds Cove is low lying & may possibly be underlain by sediment although the gabbro veins all along the shore as far as Reynolds Cove Point. Rounding Reynolds Cove Point which is a mass of gabbro (=1085) we cross suddenly upon a mass of limestone while gas under the gabbro and which form a cliff 15 feet high. These are calcareous lensels from 1 to 3 inches thick inter- stratified with bands of equal thickness of more grayish limestone. These are hardly more than a couple of miles of them slaty parting in the entire section. The limestones are nearly horizontal striking generally N. 35° E. and dipping slight 10 degrees Ethe south 55° hit- at the point the rebov land for a sample of rods and gas beneath striking N. 26 W. and dipping 15° E. 20° N. The gabbro overlying cuts across as an uneven angle resembling an erosion unconformity and thereby is also and still as represented in the sketch
