EXPERIMENT STATION RECORD. 



7.112 lbs. as compared with 3,710 lbs. for Turkestan. In 1908, however, it was 

 slightly exceeded by S. P. I. No. 13291. In 1909 it produced a liigher yield 

 than any other variety at the first cutting, but the second crops were put into 

 the silo without weighing. In 1906 Minnesota Grimm was the only variety 

 not injured by frost, and in 1908 the superintendent of the Indian Head 

 experimental farm stated that from the first of the experiments " Grimm alfalfa 

 lias never been winter or spring killed in the least." 



The author reports the experiences of numerous farmers who have had good 

 results with Grimm alfalfa, discusses its forage and seed producing capacity, 

 general behavior, temperature relations, and drought resistance, and sum- 

 marizes its behavior, stating that in the North its effective growth begins earlier 

 and continues later than that of any other strain successfully cultivated there, 

 and that it has unusual vigor, earliness, and yielding power in seed production. 

 It is up to the average in drought resistance and in Minnesota usually produces 

 3 good hay crops and enough additional growth for pasture or hog feed.

Barley: Growing the crop, H. B. Derr {U. *Sf. Dept. Agr., Farmers' Bui. 

 ■^43, pp. .'/8, figs. 17). — The author presents an illustration of a new hybrid awn- 

 less barley (E. S. R., 24, p. 335), which he calls Arlington Awnless. The prin- 

 cipal topics dealt with in the text of the bulletin are the origin and history of 

 barley; its botanical characters; its introduction into the United States; its 

 soil, climatic, and moisture requirements; and directions for improving, pro- 

 ducing, and storing the crop. 



The author cites experimental data from sources already noted, and reports 

 variety tests conducted at a number of points in the barley-growing area. The 

 yields of the more productive varieties are stated in the following table :

a As the legal weight of hulless harley is 60 lbs. per bushel, and that of hulled barley only 48 lbs. per 

 bushel, the yields in pounds of hulless barley in some cases in these tests were greater in case of certain 

 hulled varieties although the number of bushels reported for the hulless varieties were smaller-
