formal, popular style, and are limited to eight pages.
Timothy-seed production. Morgan W. Evans, Bureau of Plant Industry. 8 p.,
illus. (Leaf. 115L.) Price, 5f.
Many factors determine the use made of the timothy crop. When rainfall
delays harvesting a crop intended for hay, It is then harvested for seeil. When
the price of hay becomes low, some of the timothy acreage is harvested for seed.
The Department Bulletins are technical or scientific in nature and apply to a special
crop, industry, or locality. This series ends with no. 1500, and is succeeded by the
Technical Bulletin series. The editions are limited.

of gin stands. Charles A. Bennett, Bureau of Agricultural Engineering, and

These tests were conducted because ginning time per bale per fixed number of

because misunderstanding prevails as to what factors influence the rate of ginning.

nature as that in the Technical Bulletin series.
