In this calendar, a few of the most common plants are 
selected, because the change in these at the time of flow-

dissetninated through the country ; and are, therefore the 
est species for corresponding observations. The first col- 
umn marks the first change in the foliation of a forest of 
oaks, chesnut, maple, and birch, perceptible at Be dis- 
tance of half a mile. This change, it is well known, is 
generally very rapid and distinguishable ; and therefore it 
was thought proper to be noticed.
