238 GEOLOGY OF THE THIRD DISTRICT. 



of waters in opposite directions, patient investigation in time, if true, will harmonize their 

 results ; for truths only apparently conflict with each other, the real conflict being solely in 

 the minds of those occupied with them. 



Otsego Lake. 



This is a handsome sheet of water, and is elevated 1193 feet above the ocean. It has a 

 high ridge of the Hamilton group on the east side, a low and an interrupted range of the same 

 on the west side, and an elevated projection at the northeast end, the lake extending further 

 north on its west side, with an inlet on its east side. At the south end there is a dyke of allu- 

 vial, upon which Cooperstown is seated. The valley of which the lake forms the head, spreads 

 out to the southwest, the lake being one of the head waters of the Susquehannah. Length 

 of the lake about seven and a half miles ; average width, one mile and a half. 



Schuyler's Lake. 



This is also one of the head waters of the same river, and is surrounded by the same group 

 of rocks ; the country less hilly. The lake in great part appears to have been formed by a 

 dam or dyke of alluvial, the materials having been carried into its depression from its sides. 

 Another dam occurs lower down at Oakville ; and a third one, yet lower, at the factory. 

 Length of the lake nearly four miles. 



Cazenovia Lake. 



This is a beautiful lake of its size, the high points around it consisting of the Hamilton 

 group, and the lake extending into the Marcellus shales at its north end. It divides north into 

 two branches, one heading towards the valley of Limestone creek. It discharges its waters at 

 the south end, which flow into Chittenango creek. 



Otisco Lake. 



This is a small lake, deeply seated in the Hamilton group, its waters flowing north. The 

 hills rise south ; its inlet narrow ; forming a valley whose hill-sides rise three hundred feet 

 above its surface. The bottom of the valley forms an inclined plane, ascending to the broad 

 valley of Preble and Homer. Its bottom shows rolled stones of the usual kind, which are 

 thrown into hills near the large valley. Length about three miles ; average breadth about 

 half a mile. 



Skaneateles Lake. 



The sides of the northern end of this lake gradually slope to the water, corresponding in 

 inclination to each other, and adding greatly to the beauty of the lake. The south end is more
