BOTANY. 
-_-<—— 
Arr. VIII. Floral Calendar, for the years 1815, 16, 1%, 
18, and 19 ; kept at Deerfield, Mass. North Lat. 42° 28’, 
West Long. 72° 39'—One hundred miles from the sea 
coast.— By. Dr. Dennis Coouey. 
In this calendar, a few of the most common plants are 
selected, because the change in these at the time of flow- 
ering is most striking, and because they are most widely 
disseminated through the country ; and are, therefore the 
best species for corresponding observations. The first col- 
umn marks the first clange in the foliation of a forest of 
oaks, chesnut, maple, and birch, perceptible at the 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.

Remark.—Such concise results of extended observations. 
are desirable, but it may not always be convenient to insert 
very voluminous details of daily floral occurrences.—[ Ed. |
