The reasons were given for reopening the old controversy and for selecting the north end of the Taconic Mountain as the crucial place. The principal views regarding the rocks of the Taconic Mountains were briefly outlined and the geology of the region summed up. Five subdivisions of the Stockbridge limestone around the north end of the Taconlcs were described and attention was called to the extreme folding and metamorphism of the rocks. The slates of the mountains are sharply outlined from the Stockbridge limestone and the contact follows a rude semicircle around the end of the mountains. The characters of this plane of separation were discussed and the conclusion was reached that they could only be due to faulting. The bearing of this conclusion was briefly considered.
