on the southern as well as the northern slopes of the White mountain 
ranges, moving in opposite directions ; those on the northern slope 
moving northward, and those on the southern slope moving south- 
ward 
All these moraines and traces of local glaciers overlie the typical 
or northern drift, so called, wherever the latter has not been entirely 
swept away by the local glaciers themselves, thus showing that the great 
ice-sheet is anterior to the local glacier At least, wherever I have 
recognized traces of circumscribed glaciers in regions where they no 
longer exist, it has always appeared to me that the minor areas covered 
by ice were remnants of a waning sheet of greater extent 
Having in June two years ago carefully examined the 
ground northward from Bethlehem, which Agassiz thus de- 
scribed, I fully concur in his view that the morainic drift there 
was brought from the south, being amassed along the northern 
edge of ice-fields that sloped down from the north ends of the 
Franconia and Twin Mountain ranges ; but I could not trace 
the many and mainly parallel morainic ridges or series of knolls 
and hillocks which his description led me to expect. Instead of 
separate and well defined small frontal moraines, like those 
which I had seen in the glens and valleys around Ben Nevis 
and Scawfell,* marking intervals of halting in the retreat of the 
latest local glaciers, the ridged and knolly drift deposits north 
of Bethlehem appear to me to be an indivisible and promiscuous 
morainic belt, running there from east to west, with a width of 
one to one and a half miles, quite like the typical moraines of 
the continental ice-sheet in their course through Minnesota and 
adjoining states. 
Besides, from my many excursions and railroad surveying, 
in the White mountain region, and especially about the base of 
Mt. Washington, I can say confidently that recessional mor- 
aines of local glaciation, similar to those so admirably and plen- 
tifully displayed in the vicinity of the highest peaks of Scotland 
and England, are generally absent or rare among these highest 
mountains of the northeastern United States. Perhaps their 
best example is the one described by Stone, in the Androscog- 
gin valley where it crosses the line between New Hampshire 
and Maine, t But probably patient search in the great valleys 
and ravines will reveal numerous examples of such narrow
