autumn up above this trending point and the promontory just spoken of. 

 Hence the town derives little if any of the warming effects of the open 

 lake and forming ice during the winter, and especially after the first 

 frosts. The half-monthl}' averages for the two places are as follows :

From this it appears that the average is in our favor by some three or 

 four degrees, in the coldest half month (1st Feb., 3°.77) in that part of 

 the winter when their lake is shut out by frost and otherwise from any 

 influence on their climate, and ours is open and with ice constantly form- 

 ing on its banks. 



In June, however, their climate is warmer than ours, 4°.04 first half, 

 and 2°.13 last half, while our lake has not attained its midsummer heat — 

 for, being very deep, it cools slowly; but in July and August, after the 

 lake has become heated, and so prevents the cooling of the air during the 

 night, etc., our temperatui-e is the highest, 0°.96 the first half of July, 

 10.69 for the second half, 2°.83 for the first half of August, and 3°.75 for 

 last half 



I think that nothing more can be needed to confirm the theory I have 

 advanced, of the influence of our lake on our climate. 



I will, however, introduce another comparison ; that with Ithaca, at 

 the head of Cayuga lake. The physical position of the two places is as 

 follows :

Ithaca has the advantage of about half a degree of latitude and fifty 

 feet of elevation, which, combined, make scarcely so much as one degree 

 of temperature in its favor ; but it is situated at the south end of the lake,
