Remarks. 



The past year has been a peculiar one in several particulars ; but 

 is the more remarkable for the diminution of heat, and its effects on 

 vegetable life. The temperature for the year is 50°.65 ; and is 

 about four degrees less than the mean annual amount of heat for 

 this climate, and nearly two degrees less than the preceding year, 

 which was thought to be an extraordinary period in this respect. — 

 In February the mercury fell to 15° below zero, Fahr., a depression 

 considerably greater than has been experienced since the year ]818,

 effects on the peach in this vicinity were similar, but not so universal ; 

 in 1818 it destroyed the whole, of whatever age, but in 1835 the 

 old trees only were killed, while the more vigorous and younger 

 trees escaped with the loss of frost-bitten extremities. The mean 

 temperature of the winter months is 30° ; of tlse spring months 51°.
