MORAINES AND ESKERS OF THE LAST GLACIA- 
TION IN THE WHITE MOUNTAINS. 
By Warren I'tham, St. Paul, Minn. 
During the quarter of a century since the pubUcation of The 
Geology of New Hampshire, in 1874-78, by Prof. C. H. Hitch- 
cock and his assistants, nearly all that is known of the terminal 
moraines (marginal and recessional moraines) of the conti- 
nental ice-sheets has been ascertained. At the same time with 
that work on my native state, and partly in its third volume, the 
earliest elaborate descriptions of any parts of these moraines, 
with recognition of their character and origin, were published 
by Cook,* Chamberlin,t and the present writer.! 
Within a few years later, the outermost moraine was traced 
across northern Pennsylvania by Lewis and Wright ;>5 and it 
was followed onward by A\'right through southern Ohio and 
Indiana. || Farther northwest, it was similarly traced with en- 
suing moraines of the glacial recession, by Prof. N. H. Win- 
chell and myself in Minnesota and lowa,^ and by Todd in 
South and North Dakota. ° 
Correlating all these observations, Chamberlin twenty years 
ago published descriptions and maps of the complex system of 
the outer marginal moraines in all their course across the north- 
ern part of the east half of the United States, from Nantucket 
and Cape Cod to North Dakota and Assiniboia.**
