From these figures it may be computed that 48 per ct. of all 
the seeds set germinated the first day of germination. Between 
1.14 and 1.17 inclusive fifty-eight seeds are included and of these, 
thirty-cur, or 59 per ct., germinated in the same time. All others 
are thirty-one seeds, of which nine, or 29 per ct. only, germinated 
the third day. it ihus aptears that the best germination in all 
respects took place between 1.14 and 1.17. The reserve material 
in cruciferous seeds is characteristically in the form of oil, and 
Kobayashi, as already stated,* has shown that the greatest per- 
centage of oil is contained in cruciferous seeds of medium specific 
gravity. This one trial would indicate, then, that vigor of germi- 
nation is correlated with storage of reserve material. 
TIMOTHY. 
Tests with timothy seed resulted as follows:

Timothy seed does not lend itself well to separation by salt 
solutions, at least in the small way in which the writer has con- 
ducted his experiments. Perhaps on a large scale, especially 
where a quantity of seed was being separated in a large recepta- 
cle, the method would be applicable. It appears from these 
results that, as a matter of agricultural practice, it would be easy 
to get rid of a large part of the ungerminable seeds in fresh 
timothy seed by simply immersing the seed in a saturated sait 
solution (1.20) and planting only the seeds which sank. 
CLOVER. 
A sample of fresh clover seed showed in the separates less than 
1.20 only three germinations out of sixteen seeds. These separ- 
ates consisted mostly of small (foreign) seeds. The percentage of 
germination in the separates 1.20 to 1.24 was low. Between 1.25 
and 1.50 the percentage of germination was high. Above 1.30
