and in some places completely, buried beneath the river-silt 

 which forms the present flood-plain. In one case, a few 

 miles below Lowell, the end of this ridge, completely cov- 

 ered with river-silt, may be seen where the river has cut 

 across the old barrier. Professor Charles Hitchcock gives 

 a similar section of a buried kame in Hanover, N. H, though

in this case it is parallel with the river, and not, as in the 

 other, at right angles to it.* 



Inasmuch as the interpretation of the facts in the valley 

 of the Connecticut is open to some question, and as the de- 

 cision with respect to them will have an important bearing 

 on our whole conception of the closing scenes of the Glacial 

 period, it will be worth while to consider them more fully. 



Mr. Upham, in his survey of the Connecticut Valley, f 

 discovered what he considered to be a line of kames extend- 

 ing throughout nearly the whole length of the valley, though 

 it had been much eroded in places, and in others was partially 

 or completely buried by river-silt ; but of the character of the 

 deposit as a true kame he felt quite confident— that is, he con- 

 sidered that the line of gravel ridges which he found winding 

 from side to side down this valley were deposited as the ice 

 retreated, after the manner we have described in channels 

 and tunnels formed near the front. In this view these ridges 

 in age are intermediate between the till and the regular river
