The borders of the lake are composed principally 
a. Fag illaceous slate, which extends back to the more ele- 
ridges, where, in many places, it is overlaid by gray~

alternates with them 
n the eastern shore of the Lake, three miles from its 
aie ‘termination, there is, a_ singular and interes- 
ratification of these rocks, at a place called Snake 
Hil, This hil projects into the lake for some distance, 
and rises abruptly more than two hundred feet above the 
Jevel of the water, presenting a naked and almost perpen- 
dicular front, which looks to the west and south-west, 
where the different strata are as regular and well defined 
as though they were painted ona wall. They rise from 
the water in regular succession along the southern part of 
this front and pursue an elevation of from 13 to 15° to 
ihe norili-west, in straight and parallel NUP until they 
arr.ve towards ‘the northern termination of t 8 promon- 
tory; here they make an abrupt curve sae =. up the 
» mountain in an oblique direction, to its summit, producing 
a declination exactly in an opposite direction. The curve 
made by the strata, taking an opposite course, is the seg- 
ment of a circle, the diameter of which would not exceed 
“20 0r 30 inches. ‘The strata are of different dimensions, 
varying from half an inch to two feet in thickness and consist * 
of alternate layers of argillaceous slate and gray-wacke or. 
aray-wackeslate. The gray-wacke contains impressions of 
shells in great abundance, they cousist principally of by- 
valyes, an id both the formations effervesce with acids. :
