Xhe measurements were made February 11, 1910, for comparison of open-fertilized and hand-pollinated lots of seed. January, 1910, were planted to study the effect of the different par- ents on vigor of the young seedKngs. These lots of seedlings varied markedly in average size, and it was easily seen that the open-fertihzed lots of seed as a rule were shorter than the hand-pollinated lot from the same female plant. The accompanying diagram (fig. 2) shows the average heights on February 11 of the entire series of seedlings arranged in classes showing the different lots of hand- pollinated seed with the sample check from the same female. The check is shown in black with the different pedigreed lots following in outline. A study of the diagram shows that wherever male A7-83 263.
