 The three bays projecting southward from 

 this part of the lake all end in swamps 

 which unite together and extend a consid- 

 erable 'distance south through a depression 

 which is a mile or more in width, with 

 French Mountain upon the west flanked all 

 the way by a lateral moraine. The swamp 

 is finally interrupted by a beautiful drum- 



five or fifty feet above Lake George ; 

 while to the south gravel deposits fill the 

 whole area to Half-way Brook, not more 

 than a mile distant. There are some of the 

 most enormous dry kettle holes in this ai-ea 

 that I have ever seen. It would be a very 

 easy matter to dig a canal which would turn 

 the water of Lake George in this direction 

 and deprive Ticonderoga of its water power.

lin about 250 feet high, one mile in length, 

 and one-third of a mile in width. This is 

 as typical in every respect of this class of 

 hills as any which can be found in eastern 

 Massachusetts, its longer axis being par- 

 allel with the valley; but it is not broad 

 enough completely to fill the valley. On 

 either side of it the watershed occurs in 

 low-lying swamps not more than twenty- 



The results of the investigations may be 

 summarized in the following genei'al state- 

 ments : 



1. The preglacial course of the Hudson 

 was probably directly south from Corinth 

 between Mt. McGregor and the Kaya- 

 derosseras range. This was filled up by 

 glacial deposits at South Corinth to such a 

 height that upon the retreat of the ice the
