Cultural methods for wheat- growing in dry districts, G. L. Sutton {Dept. 

 Agr. .Y. ,S. H'm/cv. Fanners' linl. 32, pp: 35, figs. 29). — This is a manual of infor- 

 mation as to wheat production under dry farming conditions. 



Prizes for improved wheats (Jour. Dept. Agr. So. Aust., 13 (1910), No. 9, 

 pp. 730-735). — The author states the principal regulations goveruiug prizes for 

 new wheats or improved strains of existing varieties specially adapted to 

 (1) south of Adelaide, (2) the Lower North, and (3) the Upper North. The 

 milling results of each of the wheats entered in competition are given, together 

 with tables presenting the purity of seed yield, strength of straw, and other 

 points of interest. In two of these districts the Federation variety made the 

 highest average yield and highest total score of points, but the judges decided 

 that none of the wheats justified tlie payment of prize money. 



Results of seed investigations for 1908-9, L. H. Pammel and Charlotte M. 

 King (Iowa Sta. Bui. 115, pp. 156-177, fig. 1). — This bulletin gives summaries 

 of the results of purity and germination tests made in 1908-9 of the seed of 

 clovers, alfalfa, and timothy. 



The germination tests were made between blotters, in sand indoors, and in 

 the field. Seeds grown in 1906 were tested indoors in sand in April, 1907, and 

 in the field in July, 1909. The respective results by the 2 methods were for 

 red clover 87.5 and 20.2, mnmmoth clover 84.3 and 14.3, alsike clover 82.6 and 

 33.3, alfalfa 80 and 33.3, and white clover 76.6 and 5.3 per cent. Seed grown 

 in 1907 was tested in the field May 1, 1908, and July 5, 1909, with these respec- 

 tive results: Red clover 56 and 5.7, blue grass 23 and 12, timothy 49 and 17, 

 mammoth clover 85 and 67, alsike clover 56.5 and 59, and alfalfa 55 and 59 

 per cent. 



A table shows the weight of seeds of different kinds and the number of seeds 

 required to weigh 1 gm., to constitute 1 per cent of a 5 gm. sample, and to 

 constitute 1 per cent of a 4 gm. sample. A simple method for the home analysis 

 of seeds without the use of scales is described. Notes on the delayed vitality 

 of weed seeds are followed by a bibliography. 



Seeds of Michigan weeds, W. J. Beal (Michigan Sta. B^d. 260, pp. 101-182,

 1909, G. LiND (K. Landtbr. Akad. Ilandl. och Tidslcr., -Y-) (1910), No. 3, pp. 

 161-213, figs. 2Jf). — Results of these tests indicate that in many cases seedsmen 

 do not sell varieties true to name and the culture of pure strains of domestic 

 seed adapted to Swedish conditions is recommended, the supervision and pro- 

 duction of this seed to be in the hands of experienced and reliable grf)wers.
