"the quartzite and conglomerate as at Birdy Cove and in all probability are the same beds. The question to be asked are they on the same beds?" All of the strata of Birdy Island except the quartzite and conglomerate are extremely crumpled and mashed into one another and some of the thin sandstones are so broken up and the pieces separated from one another as to make it impossible to trace their fold. The shales were much squeezed and locally overthrust into one another. Then a decided cleavage is developed. What ever fossils are present are now not in sight due to the mashing and cleavage. If there were an abundance of them limestone tends on chances for fossils would be better. Nor has a single fossil been found in Birdy Island. The leary hidden conglomerate has a dip of 30°S, and a strike N.70°W. The quartzite has a strike of N.20 W. and a dip of 40° E. The dip may rise to 60° W. The cleaved shales standing vertical and parallel to the bedding planes had a strike of N.70 E. and a dip of 80°W. The direction of pressure to produce the cleavage came from N.20 W. The folds are more or less closed but not completely or as we see at least two folds on the northern main land opposite Birdy Island. On the tip of Birdy Island along the road crossing the island we saw a large erratic of red granite. Blomidon Mt (2120') to the east of the Ordovician is em-
