It has been observed by agriculturists, tho thus far without explanation, 

 that there is a difference in the condition of crops and fruits on the two 

 sides of the lake. This has been found true also in the life histories of the 

 membracids, the forms on the west side of the lake being later in appear- 

 ance and slower in development than those on the east side. But, as in 

 the case of the plants, no reason for this difference is forthcoming. Whether 

 such variation has been observed for any other insects is not known. 



The climate thruout the basin is variable, showing rather extreme 

 ranges in temperature thruout the year; and, owing partly to differences 

 in elevation and partly to protection from or exposure to winds, some 

 sections of the area under consideration are quite different in climate from 

 others. The territory represented by the eastern and the southern hills 

 is notably colder than the sheltered stations in the valley, and these 

 regions have a much greater snowfall. The western and the northern 

 stations are, on the other hand, warmer and show less snow and less 

 intensity of winds. 



The city of Ithaca, at the head of the lake, may be taken as giving a 

 fair average for the basin. The temperatures for this station are shown in 

 the following table, which has been compiled from figures extending over 

 the last thirty-five years:
