Hop culture in California, D. Flint ( U. S. Dept. Agr., Farmer-^' Bui. 11.5, pp. 26, 

 Ji(jH.2). — This 1)ulletin discusses the methods of hop culture followed in California, 

 including systems of training, tying up the vines, harvesting, curing, baling, mar- 

 keting, and the prices, wages, and expenses involved in hop growing in that State. 

 Some introductory remarks on the botanical features of the hop plant, varieties of 

 h(jps grown in this country, counties in Ca'lifornia devoted to hop culture, and the 

 climatic conditions of California are given. Some hop statistics prepared by the 

 Division of Statistics of this Department as to the acreage, yield, and value of hops in 

 the United States in 1889 and 1890 conclude the bulletin. 



Our mustards and their role in agriculture, A. Barot (Ao.s moiitardes et lenr 

 role en (ujricnltnre. Pari.v CJiarles Mendel, pp. 6.3). 



Tests of Alinit in the culture of oats and barley, A. Damse.vux {Bui. Agr. 

 IBmssehi], 13 {1899), No. 7, pp. 615, 616). — Oats were not benefited by the use of 

 Alinit. Barley gave increased yields of both grain and straU' seemingly due to its 

 action. 



Oil-producing plants and their culture, V. Kries {Deut. Landu: Pres.se, 27 

 {1900), No. 63, pp. 784, 78.5). — The various sorts of rape are dealt with especially. 



Potato raising in Canada, W. T. Macoun {Amer. Gard., 21 {1900), No. 298, pp. 

 597-599) . — The author states that the average yield of potatoes in Ontario is 115 bu. 

 per acre. The average yield of 15 varieties at the Central Experimental Farm in 

 1898 was 240 bu. per acre. This difference in yield is thought to be largely due to 

 more careful selection of seed and varieties by the station than is usuallj^ given by 

 farmers. Of white-skinned varieties American Wonder, Empire State, and Carmen 

 No. 1 are recommended, and of pink potatoes Everett and Eochester Rose. Early 

 Ohio is considered a good potato for the early market. Seed, cultural methods, 

 spraying, world's production of potatoes, etc., are other subjects discussed in _ the 

 article. 



Experiments on pasture {Farm and Horne, 19 {1900), No. 963, p. 229). — Some 

 details as to the effect of various manurial dressings are reported. 



Experiments on pasture, 1900 {Agr. Students' Gaz., n. ser., 10 {1900), No. 1, 

 pp. 16-19). — Data on the hay yield of a large number of plats differently fertilized 

 with commercial fertilizers and barnyard manure. 



Manurial experiments in Devon {Farm and Home, 19 {1900), No. 963, p. 228). — 

 A summarized report of results obtained by the Devon County Technical Education 

 Committee in manurial experiments with root crops, potatoes, and grass. 



Breeding experiments -with rye and -wheat, M. Fischer {Fi'tldtng\s Landw. 

 Ztg., 49 {1900), Nos. 16, pp. 609-613; 17, pp. 642-649, figs. .^).— The interrelation of 

 quality and color of the grain was studied. 



Three years' fertilizer expei^ments with rye on light soil {Deut. Landw. 

 I'resse, 27 {1900), No. 69, p. 861). — Plat experiments were made and 19 combinations 

 of fertilizers used. The results are tabulated. The greatest profit followed the use 

 of a mixture of 448 lbs. of kainit, 336 lbs. of Thomas slag, and 112 lbs. of nitrate of 

 soda. 



When do swedes cease growing? {Farmers' Gaz., 59 {1900), No. 26, j). 50.9). — 

 A record of measurements which show that in this test no root growth took place 

 after N(jvember 1, though there was some leaf development. 



Sugar beet analyses, A. E. SnuTXLEWORTH {Ontario Agr. Col. and Expt. Farm 

 lipt. 1899, pp. 48-50). — Analyses are given of a number of samples of sugar beets 

 pulled at different dates between October 24 and Novend)er 27. The sugar in the 

 beets ranged from 11.9 to 15.3 per cent with a purity coefficient varying from 74.1 to 

 82.5. The November-pulleil beets were richest in sugar.
