"I've studied great groups (Lamond), the Bay and slender Orthreus (Septem apart) and the Asephor tails. Above all this come in the gneissite beds. As the strata dip south westward naturally the ones one can find this afternoon just beyond the village houses are the oldest of any seen of gne W. As apparently none of this material is here of deep Cambric age it would seem that the sea of gne is time begun to form on the strata of this time and shortly after on those of the Phyllographus beds, and higher beds up to gne II. Nothing of gnes 12 and 13 was seen and certainly nothing of the sandstones of 14. As the Upper Cambric beds the strike is N. 70 E., dip 32 S. One foot mile beyond it is N. 80 W., dip 22 S. Near the lift house it is N. 35 E., dip 52 S. There are many faults usually small ones of a few feet, but several large ones were seen with a throw of at least 20 feet. The strike ranges from N. 55 E. to 75 E., and are usually vertical. These layer faults are probably not faults above but rather the edges of the great blocks of deep Cambric limestone. They look like faults but are in more probability not such. On the other hand the smaller faults are truly such for in several cases one could see the two edges of the faulted block. The thickness of the conglomerate must be more than 100 feet as given by Richardson. From Steaming Island to Car Cove it is more than 1 mile across the strike, with an average dip at 35 degrees the thickness will be nearer 1000 feet if not more. (cannot be much)
