white as fnow, from the hoary froft. The 

 Swedift thermometer was a degree and 

 a half below the freezing point. We 

 obferved no ice in the rivers or wa- 

 ters of any depth -, but upon fuch only as 

 were about three inches deep, the ice lay 

 to the thicknefs of one third part of a 

 line *. The evening before, the wind was 

 fouth, but the night was calm. The ap- 

 ple-trees and cherry-trees were in full 

 bloflbm. The peach-trees were almoft out 

 of flower. Moft of the foreft-trees had al- 

 ready got new and tender leaves, and moft 

 of them were in flower, as almoft all kinds 

 of oaks, the dog-wood, fCornus Florida), 

 hiccory, wild prunes, faffafras, horn-beam, 

 beeches, &c. 



The plants which were found damaged 

 by the froft, were the following. 1 . The 

 Hiccory. Moft of the young trees of this 

 kind had their leaves killed by the froft, fo 

 that they looked quite black in the after- 

 noon ; the leaves were confumed by froft 

 every where in the fields, near the marines, 

 and in the woods. 2. The black Oak. Se- 

 veral of thefe trees had their leaves damaged 

 by the froft. 3. The white Oak. Some 

 very young trees of this kind had loft their 



leave?
