Agronomical investigations, E. Y. Wilcox {Hawaii .S7(/. Rpt. 1914, pp. 17, 

 18, li), 20). — This outlines tlie general scope of the agronomical work of the 

 stixtion, discussing tlie rice experiments, the unsatisfactory growth of cereals, 

 the favorable prospects for Sudan grass, Giant Bermuda grass, teff grass, and 

 saltbushes as forage plants, an unsatisfactory attempt to grow potatoes on 

 account of blight, the excellent results with buckwheat and flax as farm crops, 

 the increasing use of algaroba meal, and tlie increasing use of dynamite in im- 

 proving soil conditions. The great value of the use of arsenite of soda as a 

 spray to destroy weeds is also noted. The effect of arsenic on the soil is being 

 studied. 



Report of the eastern Oregon dry farming branch experiment station, 

 Moro, Oregon, 1913-14, D. K. Stephens {Oregon Sta., Rpt. East. Oreg. Dry 

 Farming Xta., Moro, lOIS-Uf, pp. Jf2. figs. l.'i). — This bulletin embraces brief 

 notes on the establishment of the eastern Oregon dry-farming substation at 

 Mori), its equii>ment. and the climatic and soil conditions found there, including 

 meteorological data. 



liesults of experiments that ha\e been carried out along the lines of variety 

 tests, tillage experiments, and crop rotaticms are given in detail and sum- 

 marized as follows : " Improved strains of the Turkey winter wheat, in a 

 4-year period, have averaged S bu. an acre more than the local Fortyfold. For 

 a 3-year period the Kharkov winter wheat has exceeded the best local Turkey 

 wheat by 4.6 bu. an acre. Early Baart spring wheat and selections from 

 Koola, Karun, and C. T. No. 2495 have given yields from 4 to 5 bu. an acre 

 higher than the Se1e<-'ted Bluestem, the best local spring wheat. . . . 



"The average yield of G3.000 acres of sj>ring and winter barley in the Colum- 

 bia Basin counties of Oregon in 1909. according to the U. S. Census, was 15.5 

 bu. an acre. The 4-year average yields of the Mariout, Hannchen. and Swan- 

 neck spring barleys on the branch station farm have been 26 to 29 bu. an acre. 

 . . . For a 4-year average the leading oat varieties have been Kherson, Cana- 

 dian, Siberian, and Sixty Day. A selection of the Sixty Day in 1914 out- 

 yielded the best local oat variety by 20 bu. an acre. Tests with winter and 

 spring enmier indicate that this crop will not likely supplant oats and bnrley 

 for stock feed in eastern Oregon. That field peas can be grown with profit on 

 eastern Oregon dry lands has been demonstrated. The Carletou variety on 

 the same ground in 1912, 1913, and 1914 averaged 19.3 bu. an acre, at present 

 prices worth about $35. . . . 



" The best corn varieties for eastern Oregon conditions have been found to 

 be Walla Walla White Dent. Northwestern Dent. Minnesota No. 13, Windus 

 White Dent, and Yellow Flint. Corn varieties grown for a number of years 

 and .selected at the bi'auch station have always given higher yields an acre 

 than corn grown "from seed of the same varieties obtained from distant 

 localities. 



"Alfalfa in cultivated rows has given promising rosulls on the dry upland 

 soils. The Baltic and Grimm varieties are recommended as best suited to 

 eastern Oregon conditions. 



" The permanency of the agriculture of eastern Oregon will depend upon the 

 adoption by the farmers at some time of a crop rotation scheme that will 

 increase and maintain the fertility of soil that is being depleted by continuous 

 grain growing. Eighteen different croj) i-otation schemes ai-e being tried at the
