DESCRIPTIONS OF THE VARIETIES. 25 



The namo, Buttorball, Avas given to this variety on account of its round yellow seeds.

AMHERST. 



A rather low and stocky, well-branched variety, with large leaves and broad jxhIs. 

 Stems medium to stout, one-fourth to seven-sixteenths inch in thickness, 12 to 21 or 

 30 inches high; branches not numerous, ascending or appressed, the lower nearly as 

 loTig as the stem and arising from very near its base; leaves very Vtroad and large, 

 medium green in color; pods very large, 14 to 2} inches long, one-half inch broad, 2 

 or 3 seeded, Ijorne on stem and branches almost to the ground. The seeds are large, 

 spherical, 7 to 9 mm. in diameter, often scarcely flutlened in dorsal view, deep yellow 

 with a slight greenish tinge, becoming paler and duller witli age; hilum yclloM' or 

 brownish. 



The time required for the Amherst variety to reach maturity varies from onr huiidre 1 

 and five to one lumdred and thirty days, the average being al)out one luuuh'cd and 

 fifteen to one hundred and twenty days. It ripens a few days later than the Guclpli 

 variety, which it somewhat resembles except in being considerably smaller. It has 

 been grown successfully in the Northern States and is reported as a fair to good yielder. 

 Tests at Washington, D. C, have given from 5 to more than 20 bushels to the acre; 

 the Kansas Agricultural Experiment Station reports 10 l)ushels, while the Kentucky 

 station quotes yields of from 2(5 to 40 bu.shels to the acre. 



It will be noted that the greeni.sh tinge on the seeds indicates the relationshi]) of tliis 

 with the three greenish yellow varieties. Insjiection of the tables will show tliat it 

 lies between Yosho and Ilaberlandt in size and maturity, and rather nearer to the 

 latter in both. In habit it is also very near Haberlandt. 



This variety was named for the Massachu-setts Agricultural Experiment Station, at 

 Andierst, Mass., where soy 1)eans have been cultivated for many years from specially' 

 imported seed.

HOLLYBROOK. 



A fairly large, medium late variety, with long appressed or ascending branches. 

 Stems fairly stout, one-fourth to three-eighths or one-half inch in diamet,er at the 

 base, 20 to 36 inches tall, 25 to 30 inches representing the average height; branches 

 nearly as long as the main stem, appressed or ascending; leaves large, medium green 

 in color, pods quite thickly set on stem and branches, medium in size, 1 to 1^ inches 

 long, three-eighths inch wide, mostly 2 seeded. Seeds medium in size, 6 to 7 mm. 

 wide, 6 to 8 mm. long, some spherical, mostly broadly elliptical, somewhat flattened 

 in dorso-ventral view, deep or lemon yellow, very shiny, becoming paler and duller 

 with age; hilum usually pale brown. 



For the most part this variety has been too late to mature in the Northern States, 

 though it has been called early in Massachusetts and Rhode Island in a favorable 

 season. It requires from one hundred and ten to one hundred and thirty-five days 

 to reach maturity, the average being about one hundred and twenty days. Yields
