half of what I said it was; and as to the recognition of the 
Bunter sandstein, the Muscholkalk and the Keuper, Dr. New- 
berry said, whether those three formations "will ever be fully 
identified in New Mexico, I regard as doubtful." 
So that Dr. Newberry in his exploration of New Mexico of 
185S. five years after my exploration of 1853, and with all my 
publications available, did not recognize the Dyas (Permian), 
admitted reluctantly half the thickness of strata which I have 
referred to the Triassic, did not recognize the Jurassic system 
at a single place where I had located it, and finally recorded 
the existence of the Gryphcba ■pitclierV of the Indian territory 
and Texas, at Moquis Pueblo, at Cafioncito Bonito, at Covere 
and on the bank of the Ptio Pecos, which if it had been proved 
correct by the numerous explorations made since, would have 
shown that Dr. Newberry had discovered the Neocomian in 
New Mexico.

GLACIATION OF MOUNTAINS IN NEW ENGLAND AND 
NEW YORK. 
By Warren Upham.

Mountains have special interest for the glacialist in their 
testimony of the direction of the currents of the ice-sheet and 
its maximum thickness ; and nowhere are mountains more 
instructive in this respect than in New England and New 
York. If we include also northeastern Pennsylvania, we find 
here the only summits that stood above the surface of the ice- 
sheet on the north-eastern part of this continent, excepting 
that in northern Labrador, adjoining Hudson strait, moun- 
tains similarly rose above it. The top of Katahdin, of Mt. 
Wa.«ihington, and of the Adirondacks projected above the ice 
during tiie greater part of the epochs of glaciation, but, except- 
ing Katahdin, were wholly covered when the ice attained

Texas. Lately, January 1SS9, professor Francis W. Cragin ha.s recog- 
nized the Neocomian, characterized by the oripinal Gryph.ra }>itrheri 
at Belvidere (Kansa.s), on Medicine river, south of the Great bend 
of the Arkansas river, and ha.s traced it even as far north as McPher- 
son county, north of the Arkansas, which is the northern limit of 
Gri/f^ih.ra pitcheri and of the Neocomian (BulUlin Washburn colUge, vol.
