PHENOLOGICAL OBSERVATIONS—MACKAY. 207 
Taking these ten plants whose times of flowering range 
from April to June, it will be seen that the spring season of 
1895 was, in Nova Scotia, nearly fowr (3.8) days in advance of 
the average for the four years, while that of 1894 was nearly 
two (1.8) days behind. But, dividing the spring season into 
two divisions, before and after the middle of May, the first four 
plants belong to early spring and the last siz to late spring. 
The average dates of blooming, and the differences from the 
average of the four years, are shown in the following table:

This means, that the early spring of 1892 was nearly a day, 
(0.9), in advance of the average, but the late spring was retarded 
nearly three (2.7) days. Was the latter part of May in 1892, 
colder than the average? And so forth with the other items.
