The results of the Lauchstadt experiments with varieties of small grains, 

 ScHNEiUEWiND (Illiis. Latiilw. Ztg., 29 {1909), A'o. 82, pp. 77J-77.5; «&.s. in 

 Zenthh Agr. Clicm., 39 {1910), No. 2, pp. 109-1 Iff). —The yields of straw and 

 grain per hectare and the protein content of the grain of IS varieties of wheat 

 during the period 1904-1909, inclusive, are reported. Similar data are pre- 

 sented in tabular form for 9 varieties of oats and 11 of barley during the period 

 1902-1909, inclusive. 



Irrigation of grain, W. W. McLaughlin {U. S. Dept. Agr., Farmers' Bui. 

 399, pp. 23, figs. 7). — This discusses the relative merit of the various methods of 

 applying water to grain crops, explains flooding from field ditches, between 

 borders, and in checks, and gives directions for furrow or corrugation irrigation. 

 Other topics dealt with are the proper time of irrigation, the quantity of water 

 required, the relation of irrigation to the rate of seeding, and the value of irri- 

 gated grain land. The cost of growing grain per acre is estimated at $21.35, and 

 the gross returns of a crop of 40 bu. per acre at $30.40. 



Dry-land grains for western North and South Dakota, C. Salmon {U. S. 

 Dept. Agr., Bur. Plant Indiix. Circ. 59, pp. 2-'f, fig. i).— This paper reports results 

 obtained by the Office of Grain Investigations of this Department at Belle- 

 fourche and Highmore. S. Dak., and Dickinson, N. Dak., in cooperation with 

 the North Dakota and South Dakota stations. The soil and climate at each 

 station are discussed. 



Winter wheat was tried at each station but proved a decided success only at 

 Bellefourche. The 7 best varieties averaged 23.4 bu. per acre, while 7 varieties 

 of Durum wheat on similar ground yielded 23.2 bu. per acre. The best Durum 

 wheat yielded 18 to 40 per cent more than the best common spring wheat, but 

 this difference was increased to 75 to 100 per cent in seasons of unusually low 

 rainfall. The difference in yield is more than enough to offset the difference in 

 price. 



Progress reports are given of tests of rate of seeding, time of seeding, and the 

 milling and baking qualities of a number of wheats. 



Other results indicate that extensive areas in the northern Great Plains will 

 produce winter wheat profitably, that the only sure way of securing a crop of 

 winter wheat is to grow it on summer fallow land, and that early varieties of 

 oats will usually produce the greatest yields. Two-rowed barley uniformly 

 produced the highest yields and hull-less barley the lowest yields of this grain. 



The results obtained at the 8 substations may be summarized by the following 

 table :
