The average earliness shows a difference of one day in favor of 
the earliest ripened seed, while the average yield of pods shows a 
difference of eighteen to the hundred plants in favor of the latest 
ripened seed ; the average yield of peas per plant shows a difference 
of seven grains in favor of the latest ripened seed, and the average 
of vegetation shows a difference of about one per cent also in favor 
of the latest ripened seed. 
As a whole, the differences are so slight as to be non-committal. 
When we remember, however, that in several of the varieties tested, 
the difference in time between the earliest and latest ripening pods 
is very slight, the average difference in earliness of a single day is a 
matter of consideration to those who are seeking to promote earli- 
ness in peas. The fact that lateness in maturity is accompanied by 
an increase in yield, is to be expected when we\remember that, as a 
rule, the earliest varieties are less productive than the intermediate 
or later ones. 
Tests of Ltipe and Green Seed. 
In 1883 we gathered samples of unripe seed from three varieties 
of pea, the selections varying somewhat in the degree of unripe- 
ness. On April 28, these were planted in the garden with the fol- 
lowing results:

With the exception of the third sample of William the First, the 
green seeds were only slightly immature. Itis evident that the results 
are contradictory. The sample of William the First, gathered at 
edible maturity, however, with a very feeble vegetation, gives a sur- 
prisingly large yield. It appears that the time of maturity was lit- 
tle influenced. The experiment has value only in being suggestive. 
If extreme greenness of the seed tends to increase productiveness, a. 
knowledge of the fact is valuable. The evidence suggests further 
experiment,
