My dear sir, 



I recently observed, in the Repertory, a paper signed 

 by yourself, requesting information, relative to the late 

 uncommon season. Although your views were probably 

 confined to Pennsylvania and the neighbouring states, I 

 thought it might be interesting to you to see some ac- 

 count of the climate of this extreme part of the United 

 States, more especially in those months in which vegeta-

 with Fahrenheit's scale. It is suspended about six feet 

 above the ground, and has a northern exposure.

 the extremes of heat and cold, taken each day by a self -regis- 

 tering thermometer, exposed as above.
