214 QUARTERLY JOURNAL. 



6th District, or the Western part of the State, embracing Onon- 

 daga, Auburn, Aurora, Ithaca, Prattsburgh,Canandaigua, Palmyra, 

 Rochester, Henrietta, Middlebury, Gaines, Millville, Lewiston, 

 Buffalo, Springville, Fredonia, Mayville. 



Mean temperature of Buffalo, 46^ . 23 ; Rochester, 45° . 65 ; Au- 

 burn, 45°. 97 ; Canandaigua,46°.42,which are all due to latitude 

 and elevation. The temperature of this section of the state does 

 not differ greatly from the mean for the whole state. It is par- 

 ticularly characterized for its uniformity. The average annual 

 range of the thermometer is 96°, while in the state generally it is « 

 104°. The greatest cold in the winter at Rochester, Lewiston and 

 Fredonia but little exceeds that of Long Island or New-York city. 

 Vegetation in the spring is a few days earlier than the average of f* 

 the state, and about the same as at Albany. The winds of thig 

 section are 11° more southerly than the mean for the state. 



The facts developed by observation in this district, show a i 

 change in climate which is probably due to a variety of circum 

 stances. East of this district, for example, 27 places out of 32 show ij 

 a lower mean temperature than is due to elevation and latitude ; 

 while here, all but two show a higher. 



There is a great uniformity in the extreme heat of summer 

 throughout the state. But 5 places out of 55, show a difference of 

 over three degrees from the mean of the state, which is 92°. The 

 average time for the whole state, from the blooming of the apple 

 trees to the first killing frost in autumn, is 174 days. On the west 

 end of Long Island it is twelve and a half days more, and in St. 

 Lawrence county twenty-two less ; the difference between the two 

 latter, being consequently thirty-four and a half days. 



The following table is annexed for the purpose of enabling the 

 readers of this journal to make a more general comparison of the 

 temperature of the different places spoken of in the article, with 

 those at a distance. The allowance for elevation of the place 

 above tide water is at the rate of one degree for 350 feet.
