In 1885 the Philadelphia Extra Early Pea vegetated May 
9, bloomed June 4, and was at edible maturity June 22. 
In 1886 the same variety vegetated April 24, bloomed May 
26 and was edible June 11. The sums of the mean daily 
temperatures for the two years were:

Or practically the same, notwithstanding the difference 
of planting, and that the period from vegetation to maturity 
varies 4 days in the two plantings. 
In 1885, Pride of the North dent corn vegetated June 
1, silked Aug. 3, or in 64 days; in 1886, the same variety vege- 
tated May 31 and silked July 30, or in 61 days. The sums 
of the temperatures during these periods were as below:

Or a mean air temperature of about 70 ° during the period 
from vegetation to bloom in both cases, but the higher tem- 
perature of June in 1886 seemed favorable to a quicker de- 
velopment of the plant than the lower mean temperature 
of June in 1885, although the July temperature was highest 
in 1885.
