heavier, while the largest was 141.7 per cent. The lightest seeds 
in the large cones exceeded the smallest seeds by 41 per cent, and 
the largest seeds were 164 per cent heavier than the smallest seeds. 
Table VI shows that it is the size of seed rather than position 
in the cones which is the determining factor, there being a decided 
decline in the germination per cent with the size, while apparently 
no relation holds between position and germination. It has been 
shown that the weight of the seed is directly influenced by the

size of cone, and this is further reflected in the germination. Chart- 
ing the weight and germination, it was found that a straight line 
relation existed, which is expressed in table VII. A curious rela- 
tion was shown in the rapidity of germination. Seeds from the 
lower portion of the cones completed half their germination five 
days sooner than seeds from the middle third of the cone, which in 
turn were five days earlier than seeds from the upper part of the 
cone. Apparently this was independent of the size of the seeds 
and varied with the size of the cone, the seeds from the larger 
cone being the more rapid. Final germination apparently did not 
conform to any regularity, except that the seeds from larger cones
