ably diU' t<< the fact stated by writers on Japanese agriculture that the green-seeded 

 and the brown-seeded forms are but sparingly cultivati'd in the Orient, the blacks and 

 yellows being much preferred. 



Tlie (iuel])h soy bean has l)ecome quite a favorite in the Northern States of this 

 country, where it is highly esteemed for both seed and forage i)roduction. In Kan- 

 sas, Indiana, Michigan, and in Ontario it has given splendid results in comparative 

 tests extending through several years. 



TheOuelph variet y.grows from 24 to 38 inches high, stems medium stout, one-fourth 

 to three-eighths inch in diameter, well branched with ascending or spreading 

 branches, G inches long at the bottom, often completely filling the space between rows 

 3 to 3i feet apart. The leaves are very dark green, large and full in the center, with 

 the margin often much wrinkled or crinkly, due to vigorous but uneven growth of tlie 

 different parts of the leaf. The pods are medium in size, 1 to li inches long by three- 

 eighths inch wide, 2 to 3 seeded, borne thickly on the main stem and branches and 

 usually far enough above the ground to permit easy harvesting. The seeds are nearly 

 round in outline, 6 to 8 mm. in diameter, distinctly flattened, 4 to 5 mm. thick in 

 dorso-ventral view. In color they are bright grt-en and (|uile shiny. 



The Guelph variety is medium in time of ripening, varying from one hundred and 

 five to one hundred and twenty days, one hundred and eight to one hundred and four- 

 teen days being the average time. Six lots of this variety tested at the Kan.sas Exper- 

 iment Station in 1903 all ripened in one hundred and seven days, yielding from 3| 

 to 10^ bushels of seed to the acre and averaging 6* bushels. Eight lots tested at Wash- 

 ington the same year matured in one hundred and five to one hundred and fifteen 

 days, yielding from 5| to 14 ^'^ bushels to the acre, the average being 8? bushels. Yields 

 of from 16 to 18 l)U.shels were secured in Indiana. At the Ontario Experiment Farm 

 the average annual yield of green fodtler for a period of four years was 1 1 tons to the 

 acre. Virginia and Delaware report yields of 7 to 10 tons of green forage to the acre. 

 This' variety shatters rath(>r badly if allowed to become fully ripe, which is an oljjec- 

 tion to its use as a seed crop. Its large size and freely l)rancliing habit make it a most 

 excellent variety for pasture, hay, silage, and cover crop, and for these purposes it 

 should be widely grown. 



At the Ontario Agricultural College and Experiment Farm, loc-ated at Guelph, 

 Ontario, a great deal of work has been done with soy beans, and with this variety 

 especially, and the name is given for that reason. ^

Greenish- Yellow-Seeded Group. 



YOSHO. 



The Yosho is a rather small, early form, with small stems, one-fourth inch in thick- 

 ness, 12 to 30 inches high, with a few rather short branches, 2 to 4 inches long, rather 

 stocky and bushy in appearance. Leaves large, medium green in color; pods only 

 fairly aljundant, medium sized, 1^ to If inches long by three-eighths inch or more wide, 

 2 or occasionally 3 seeded. The seeds are medium to large in size, 6 J to 7^ mm. wide,
