and AVhite Tartar, each 30.31 bu. The yield of varieties of coruiuou wheat pro- 

 ducing 10 bu. or more per acre were: No. Oleic, 17.5 bu.. Velvet Chaff, 16.10 

 bu.. Blue Stem, 13.58 bu., No. 2492, 13.08 bu.. Minnesota, 13.05 bu., and South 

 Dakota Climax, 10 bu. Small areas of Einkorn and Emmer, seeded at the rate 

 of 2 bu. per acre, yielded at the rate of .500 lbs. of grain per acre of the former, 

 and 31.77 bu. of grain per acre of the latter. 



In a variety test of barley at Iliglunore and Brookings covering the years 

 190.3-1908, the average yields per acre were: Strlegum, 27.3 bu., Gold .Melon, 

 29.79 bu., Minnesota, .34.5 bu., Princess, 31.25 1)U., Chevalier, .37.9 bu., Hannchen, 

 .37.68 bu., Primus, 31.99 bu., Hanna No, 24, 31.10 bu., Hanna No. 203, 29.43 bu., 

 and Hanna No. 34, 29.71 bu. 



In a test of 15 varieties of corn, the 5 highest yields were: Selection 1.33, 

 .30.89 bu. per acre, Minnesota 13, 30.57 bu., Rustler White Dent, .30..53 bu.. 

 Triumph Yellow Flint, 29.73 bu., and Northwestern Dent, 28.98 bu. 



The results of rotation experiments with wheat, oats, corn, barley, brome 

 grass, rye, iteas, sweet clover, and sorghum, in various combinations, are pre- 

 sented to show the relative merits of disking, fall and spring plowing, green 

 manuring, summer fallow, listing, and moisture conservation methods. 



Fall and winter forage crops, E. de Cillis {1st. Agr. Biciliano " Valdisavoja " 

 Relaz. 1906-1908, pp. 147-155, figs. //). — The results of experiments with forage 

 crops conducted for 2 years have shown that horse beans, berseem, and vetch 

 are best adapted to Sicilian conditions. Crimson clover proved a failure. 

 Berseem gave the best yields when grown alone, while horse beans were most 

 l)roductive when mixed with oats. A variety called white vetch gave better 

 results than hairy vetch. A single cutting of berseem during the season gave a 

 better yield than 2 cuttings. An application of superphosphate, lime, and 

 sulphate of potash increased the yield of horse beans considerably. 



[Work with sugar beets and potatoes], R. W. Thatcher {Washington Sta. 

 Rpt. 1906, pp. 19-21). — Analyses of 124 samples of sugar beets grown in the 

 vicinity of Ellensburg indicated that beets of high quality can be grown in that 

 locality. 



Starch determinations of 237 potato samples from various parts of the State 

 indicated great variations in the starch content of the different varieties and in 

 the same variety from the various localities. In no case was the starch con- 

 tent of a single variety constant for the different localities in which it was 

 grown. The percentage of starch varied in general inversely with the amount 

 of annual rainfall, the highest starch content being found in potatoes grown 

 in the drier sections of the State. Of the methods of determining the starch 

 content tested the polariscopic method proved apparently worthless for the 

 purijose, but the official and specific gravity methods agreed quite closely. The 

 work was carried out by M. T. Brislawn as a senior thesis. 



A lesson in diversified farming, R. H. Forbes {Arizona Sta. Bui. 60, pp. 

 .'il7-.'i26). — This experiment was conducted in continuation of work previously 

 reported (E. S. R., 20, p. 326). 



Conditions during the past year were more favorable than formerly. Diver- 

 sification was attempted to a much greater extent than in the previous year 

 when dependence was placed upon tomatoes. The most successful crops grown 

 were white Bermuda onions, Rockyford cantaloups, sweet potatoes, and to- 

 matoes. The crop of late watermelons was destroyed by plant lice, the fall 

 crop of potatoes was a failure, and the spring crop gave poor returns. The 

 varieties of tomatoes giving the most favorable results were Sparks Earliana 

 and Dwarf Champion. Several new varieties proved ill-adapted to the i-egiou.
