west to east, deserve to be carefully studied. The valley of 
Wild River, too, promises to afford traces of local glaciers 
whenever it shall be carefully explored. 
We have called attention to the few facts which we have 
noticed in the eastern section of the White Mountains. We 
do not propose to theorize upon the relation between the 
general and the local traces at present. We prefer to await 
the farther accumulation of evidence which shall enable us 
to restore correctly the various phases of that cold period 
when vast snowfields filled the White Mountain basins, and 
huge glaciers ploughed along the White Mountain valleys, 
ving those marks upon the rocks by which we judge of 
their former presence, those convincing illustrations upon 
the last page of the geological history of the globe.
