SEPARATION OF FOREIGN MATTER FROM SEEDS BY 
MEANS OF SOLUTIONS. 
The method of separating seeds by salt solutions can some- 
times be applied to the separation of foreign matter or foreign 
seeds from the desired seeds. It is admitted, however, at the out- 
set that this consideration is of very minor importance. In sepa- 
rating a lot of clover seed, the highest separate was found to 
consist almost entirely of gravel and other inert matter. In sep- 
arating a lot of timothy, the separate above 1.30 consisted almost 
entirely of foreign seeds, apparently clover seed. In separating 
another lot of clover seed it was noticed that many of the seeds in 
the highest separate were foreign leguminous seeds quite similar 
in size and appearance, however, to the clover seed. The separates 
were planted and the results are shown in Plate XVI, fig. 3. It is 
here seen that the larger part of the plants in these higher sep- 
arates are of a foreign species. These seeds were too nearly of 
the size of clover seed to have been separated by sieving; but 
they could have been gotten rid of in larger part by discarding 
all seeds above 1.33, and almost entirely by discarding all seeds 
above 1.28. In so doing but comparatively few clover seeds 
would have been lost. 
Garman! makes mention of a practice of separating the seeds of 
certain morning glories that grow among hemp from hemp seed 
by immersing the seed in water.
