vestigation of tlie anatomy of recognized or cry ptliyb rids is likely to be of great 

 value from the genetical standpoint and will in all probability lay bare the real 

 foundation of the so-called mutation hypothesis of De Vries.

Experiments with wheat, oats, and barley in South Dakota, M. Champlin 

 (Z7. S. Dept. Agr. Bui. 89, pp. 37, pi. 1, figs, ii).— This bulletin discusses two 

 essential requirements for crop improvement, viz, better varieties and better 

 seed, and presents the results of studies pertaining thereto in regard to wheat, 

 oats, and barley as experimented with at Eureka, Highmore, Cottonwood, and 

 Brookings, in cooperation with the South Dakota Experiment Station. 



Descriptions of the leading varieties of each kind of cereal and of cultural 

 methods are given. Analyses on the composition showed the protein content 

 of the several varieties of wheat to range from 17.69 to 21 per cent, of oats 

 from 14.63 to 18.56, and of barley (6 rowed) from 16.7 to 18.8 and (2 rowed) 

 from 16.7 to 19.7 per cent. 



From the results of these experiments, which have been carried on since 

 1903 and include variety tests, the following varieties are recommended for 

 cultivation in that State: (1) Wheat: Kubanka durum (C. I. No. 1440), 

 Haynes Blue Stem (Minn. No. 169), Red Fife (C. I. No. 3081), and Fife 

 (Minn. No. 163). (2) Oats: Swedish Select (C. I. No. 134) and Sixty-Day 

 (C. I. No. 165). (3) Barley: (a) For the eastern district: Manchuria (Minn. 

 No. 105) and Odessa (C. I. No. 182). (b) For the central district: Hannchen 

 (C. I. No. 531). (c) For the western district: Gatami (C. I. No. 575), Mariout 

 (C. I. No. 261), and related varieties.
