content of straw and chaff and the dry matter content of the grain, but reduced 

 the ether extract and crude fiber in the grain. 



Hilling increased root development, but gave no corresponding increase of 

 tillering power. It increased the weight per haulm and per internode, but 

 showed vai-ying results as to length of both. With some exceptions it length- 

 ened the panicle and the number of whorls. It increased the 1,000-keruel 

 weight, chafC percentage, crude fiber of the grain, and the protein percentage of 

 the straw. As the hilled plats fell below the unbilled in both gross and net 

 income, the author concludes that hilling is valueless, but notes that these results 

 may be attributed to the fact that the condition of the soil prevented hilling at 

 the projier time. 



Bice — A possible new industry for California, G. W. Shaw and A. J. 

 Gaumnitz { California Sta. Circ. 7-'t, pp. 26, figs. 7). — This circular reports 

 studies made in order that inquiries as to the possibility of developing the rice 

 industry in California might be intelligently answered. General discussions of 

 rice culture and its soil requirements and directions for the production of the 

 crop are followed by tables and descriptive text stating the results of variety 

 and irrigation tests on a number of California farms. 



Analyses of water from a siwt where rice was growing satisfactorily and 

 from another where it appeared to be seriously affected by the alkali gave the 

 following results, the first percentage in each case being that for the water 

 which was apparently producing injurious effects: Total soluble salts, 0.6896 

 and 0.0912; chlorids, 0.1160 and 0.035; carbonates, 0.1017 and 0.0042; and 

 sulphates, 0.4719 and 0.052 per cent. 



In a depth of water test the ground was kept thoroughly wet from April 1 to 

 May 10. Water was then kept 1 in. deep from ]May 11 to May 24. and varied 

 in depth from 1 to 6 in. on different areas from May 25 to August 27. From 

 the data reported the author concludes that "the indications are quite strong 

 that the maximum quantity of water on the adobe soil should not exceed 4 in. 

 in depth and that not less than 2 in. should be used." 



Analyses made by B. A. Madson showed the composition of composite samples 

 of California-grown rice of the Japanese and Honduras types to be, respectively, 

 water 9.62 and 9.72, protein 10.06 and 11.4, fat 2.57 and 2.51, ash 1.9 and 1.61, 

 crude fiber 1.24 and 1.17, and carbohydrates 84.23 and 83.31 per cent. It is 

 concluded that the food value of the California-grown sample is as high as that 

 of the southern-grown product. 



Other tables state the amount of plant food removed by wheat and rice, the 

 labor cost of growing rice in various counties, and the duty of centrifugal 

 pumps for lifting irrigating water less than 35 ft. 



In a variety test at Biggs in 1909 an average yield of 3,486 lbs. per acre was 

 secured from plats varying in size from one-fortieth to one-tenth of an acre. 

 In 1910 an average yield of 7,089 lbs. per acre was secured from small plant- 

 ings, while an average yield of 3,820 lbs. per acre was secui'ed from another 

 series of plats ranging from 0.25 to 13.51 acres in size. 



"From all data obtainable it appears that California may ultimately be pro- 

 ducing large quantities of this valuable food product." The authors regard the 

 outlook for the industry as exceedingly encouraging, but state that this pub- 

 lication "distinctly does not wish to urge engaging in the industry in a large 

 way until more is learned concerning it." 



Soy beans as a supplementary silage crop, E. R. Minns (New York Cornell 

 Sta. Bui. 310, pp. 259-27.'/, figs. 6). — Directions for growing soy beans in New 

 York are followed by reports of the results of tests, mainly conducted by 

 farmers, some of whom cooperated with the experiment station in their test.
