Tests of Seed from the most productive and least productive plants. 
In 1883, we gathered from thirteen different varieties of pea sam- 
ples of seed from the plants that produced the largest number of 
pods, and also from those that produced the smallest number. On 
April 28, we selected the finest pods from the most productive plants 
and planted the seeds contained in them with an equal number of 
seeds from the least productive plants. ‘To avoid confusion of terms, 
we will speak of the progeny of the most productive plants as A, 
and that of the least productive ones as B. We offer the results in 
tabular form, as follows:

The outcome of this experiment is quite different from what we 
anticipated. On the average, the plants of B proved the more pro- 
ductive by two pods to the plant. Strictly, however, the plantings
