ported in tabular form. Pinched seed gave a 92 per cent germination test but 

 the plantlets were weali. 



Over 50 per cent of the untreated vs^heat was destroyed by smut in a test in 

 which but 0.33 per cent of that treated with bluestone was lost, 0.98 per cent of 

 that treated with antifungi, a proprietary mixture, 11 per cent with a 1 : 1,000 

 sulphuric-acid solution, 0.58 per cent with a 1 : 500 sulphuric-acid solution. No 

 smutted heads appeared after the use of a formalin solution (1 lb. to 50 gal. of 

 water). These figures represent average results obtained with 5 varieties. A 

 machine for use in treating wheat to prevent smut is described. 



Copper sulphate dissolved at the rate of 1 lb. in 2 gal. of water and applied 

 at the rate of 100 gal. per acre killed young mustard and radish plants as well 

 as various other weeds without permanent injury to any cereals. The grain 

 blades turned brown but resumed their usual color within 10 days. One appli- 

 cation of iron sulphate at the rate of 140 lbs. per acre killed about 65 per cent 

 of the mustard. 



Tables are given showing the yields and more important vegetative charac- 

 teristics of a large number of varieties and hybrids tested. A test of 12 varie- 

 ties indicates that "the wlieats of spreading type have-not equaled the upright 

 growing varieties," and that they are not suited to local conditions in Califor- 

 nia. The hybrid wheats were mostly of the spi'eading type and the author re- 

 gards it as " very doubtful whether they can ever be made desirable wheats for 

 California." In a test of 18 erect-growing wheats at Modesto and Ceres during 

 1907-10 the highest average yield, 51.4 bu. per acre, was produced by Bolo 

 Blanco, Cereal Investigations No. 2921. In a test of 9 durum wheats during 

 1908-9 the highest 2 year average, 40 bu. per acre, was produced by Marouani, 

 Cex'eal Investigations No. 2235-2. *In a 3-year test of wheat varieties at Tulare, 

 Theiss Cal. No. 990, produced an average yield of 43 bu. per acre, the highest 

 among the spreading varieties. The highest 3-year average yield of any erect- 

 growing variety was 47.5 bu. produced by the variety Cal. No. 907. 



Tables state the result of tests of numerous wheat varieties at Davis and in 

 the Sacramento Yalley during 1907-10 in which the results of seeding before 

 and after December 20 were compared. 



The Chul and Fretes varieties are discussed as promising wheats for Cali- 

 fornia. Historical and other data relative to them are presented, in part from 

 sources already noted (E. S. R., 16, p. 852; 23, p. 338). 



In milling tests Chul proved aboul*l per cent higher in gluten than the ordi- 

 nary California wheats, but was objected to by millers because of its hardness 

 and the fact that its volume " is slightly less than some otlier wheats. But to 

 offset this, its yield of flour is somewhat greater and the absorptive capacity of 

 the flour is higher," The average yields of Fretes and White Australian wheats 

 at the stations in Stanislaus and Yolo counties were 44.65 and 38.3 bu. per acre 

 respectively, and milling tests showed wet gluten contents of 40 and 38 per cent 

 respectively. Analyses comparing the nitrogenous constituents of 6 varieties 

 are reported. 



Memorandum, on Indian wheat for the British market, J. Wilson (Agi: 

 Research Inst. Pusa [India] Bui. 20, 1910, pp. JfO). — This paper presents studies 

 on Indian wheat for the purpose of increasing the demand for it in the United 

 Kingdom. Tables present statistical data on the imix)rts of wheat into the 

 United Kingdom, exports from India, and wheat production and prices in the 

 2 countries, and these subjects and the cleanness, purity, quality, uniformity, 

 moisture content, milling qualities, strength, and color of wheats of India are dis- 

 cussed. Suggestions are given to Indian growers and experts, and British millers 

 are urged to establish certain standards as to the wheat which they will receive.
