One tub is set above the other, as shown in figure 1. The method of procedure used in separating the grain is as follows; The upper tub is filled two-thirds full of water anil the seed barley poured in, enough space being left to allow thorough stirring. The plump barley grains will sink to the bottom, while the light and shriveled barlev and manv of the oat and weed seeds w^ill float on. Fig. 1.—Tubs showing a convenient arrangement for removing undesirable iiarley grains and oat and weed seeds from seed barley by the specific gravity methoil. the surface wlieii the grain is stirred. After stirring thoroughly, the grain that floats should be carefully skimmed off. When the skim- ming is completed, the plug should be pulled out and the water allowed to drain into the tub beneath. The grain should then be emptied from the upper tub upon a clean floor or a piece of canvas and spread out thinly to dry. The tubs can then be reversed and the operation repeated with another lot of grain. In order to dry the grain and prevent it from sprouting it should be stirred occa- sionally with a clean garden rake or shovel. This selected seed should be sown as soon as it is sulliciently dry to run through the drill. As the seed will be somewhat swollen, the [Cir. 012J.
