Haberlandt separated winter rye at specific gravity 1.30 and 
oats at 1.03 by means of salt solutions. In both cases the heavier 
kernels gave considerably the larger yield in quantity and at the 
same time the quality of the crop was better, since the average 
weight of the individual kernels from the heavier separates was 
greater than that from the lighter separates. Furthermore, the 
lighter seed gave a less proportion of grain to the amount of straw 
produced than did the heavier seed. 
Riimpler recommended the use of solutions of sodium nitrate 
for separating barley, wheat, rye, ete: He advises planting only 
the heaviest third of such seeds. 
Miiller separated barley by salt solutions into light, medium 
and heavy separates. The heaviest seed gave the largest per- 
centage of germination, the largest average number of inter- 
nodes per plant, largest vield of grain, the largest total yeild of 
vegetable matter, the highest average weight of grain per head 
and the highest average weight per kernel. 
Grandeau ‘separated oats by immersing them in water and 
made culture tests with the two separates. On the basis of equal 
areas the yield of grain from the heavier separate was 2.09 Kg., 
and of straw 6.079 Kg. From the lighter separate the yield 
of grain was 1.83 Kg. and of straw 5.71 Kg. At the market price 
of oats at the time these crops were harvested, the money value of 
the crop from the heavier seed was 14 per ct. greater than 
that from the light seed. In reporting these experiments the 
author remarks that certain other experimenters have increased 
the money value of the crop as much as 22 to 25 per ct. by thus 
separating the seed. 
Lyon separated seed, first by using a solution of calcium 
chloride and later by the use of an ordinary seed fanning mill. 
One year the yield from the heavy seed was 27.2 bu. as com- 
pared with 26.7 bu. from ordinary seed of the same sample and 
21.8 bu. from the light seed. Samples of the crops from the 
heavy and the light seed were again separated and planted the 
following year. The heavier half from the heavy sample yielded 
28.5 bu. as con.pared with 25.0 bu. from the check, while the 
lighter half from the light seed yielded only 23.9 bushels. 
Kobayashi separated rape seed into lots of different specific 
gravities by means of salt solutions. He found that seed of
