claimed to have ])oeii lued true to type, wa.s als^o grown at Lincoln, Nebr., in the 

 smniner of 1899 and u^ie<l in a few of the crossing experiments. Two ears carefully 

 inhred produced fair-sized ears which were apparently true to the type. 



Oilman Flint {Zca imliimtd Pturt.).— A light orange-yellow flint race with white 

 cob. The seed was obtained through the Seed Laboratory of this Dei)artment anil 

 it is believed was pure. One ear of this race inbred at Washington in 1898 repro- 

 duced the parent true, and the seed of this inbred ear was planted at Lincoln in 

 1899. One ear inbred in 1899 again reproduced true to typo, and the majority of 

 the ears from the plat of this race showed no effect of any mi.Kture except in two 

 ears, one of which showed wrinkled kernels like sweet corn, evidently being a case 

 of xenia due to crossing with sweet corn pollen, and the other a few blue-black 

 kernels, evidently l)eing due to xenia from crossing with pollen from Black Mexican 

 9w-eet corn which grew in an adjoining row. 



Leaming Yellow (Zen indentata Sturt.).— An orange-yellow dent with long, rather 

 slender kernels and red cob. The seed was obtained through the Seed Laboratory 

 of this Department and it is believed was pure. None of tlie plants of this race were 

 inbred, but the ears produi-ed on the plants grown and naturally fertilized gave indi- 

 cation of being from a pure race, showing no evidence of mixed origin other than 

 the xenia shown in a few ears from crossing with a white race grown next to it in 

 the field. 



Champion AVhite Peakl (Zea indentata Sturt.).— A white dent race with white 

 cob. The seed was grown by Mr. J. C. Suffern, of Voorhees, 111., and was claimed 

 to have been carefully bred under control conditions. One ear inbred in 1899 came 

 true to type. 



Boone County "White {Zea indentata Sturt.). — A white dent race with white cob. 

 The seed was grown under careful control conditions l)y Mr. James Riley, of Thorn- 

 town, Ind., the originator of the race. One ear inbred in 1899 came true to type. 



Burr's White (Zea indentata Sturt.).— A white dent race with white cob. The 

 seed was grown under careful control conditions by Mr. F. E. Burr, of Philo., 111., 

 the originator of the race. Two ears carefully inbred in 1899 came entirely true to 

 type. 



Whitecap Dent {Zea indentata Sturt.). — A race of dent corn with comparatively 

 small yellow-ish kernels with white apexes. The seed was grown by Burpee & Co., 

 and was claimed to have been produced under control conditions. One ear carefully 

 inbred in 1899 came true to type. 



Pedrkk's Perfected Golden Beauty {Zea indentata Sturt.). — An orange yellow 

 dent with red cob and broad kernels. The seed was grown by Burpee & Co. under 

 control conditions. One ear carefully in1)red in 1899 came true to type. 



Iowa Kinc; {Zea indentata Sturt.).- A white <lent race with long kernels and white 

 cob. The seed was furnished by the Seed Laboratory of this Department. 



Stowell's Evergreen {Zea saccharata Sturt.). — A clear white race of sw-eet corn 

 with long wrinkled kernels and white cob. The seed was grown by Burpee & Co. 

 under control conditions. One ear inbred in 1899 came true to type. 



Black Mexican {Zea saccharata Sturt.). — A race of sweet corn with blue-black 

 more or less wrinkled kernels and white cob. The seed was furnished by the Seed 

 Laboratory of this Department. It is believed to have been bred under control con- 

 ditions.
