How to grow wheat in Kansas, W. M. Jardine and L. E. Call (Kansaif 8ta. 

 Itul. no, pp. 3-28, figs. -)). — Experiments in 1910 testing 11 different methods 

 of preparing a seed bed for wheat are summarized as follows :

The author discusses the value of the summer fallow to the dry-land farmer 

 in western Kansas and considers briefly the 5 years" results comparing summer 

 fallowing with continuous cropping as already reported (E. S. R., 24, p. 723). 

 The author favors spring plowing for summer fallowing. Variety tests show 

 that the hard red winter sorts, to which class Turkey Red and Kharkof belong, 

 are best adapted to Kansas conditions. In the eastern tier of counties where 

 semihumid conditions prevail the soft red winter sorts, such as Zimmerman, 

 Fultz, and Currell, seem best adapted. 



Methods of cleaning the seed, treating for smuts, and controlling insects and 

 tveeds are discussed, as well as cultural methods and quality iu wheat. 



Progress of wheat investigations, C. Willis and W. L. Burlison {South 

 Dalcofa Sfa. Bui 128, pp. 123-1-',!,, figs. 5).— Statistical data on the relative acre- 

 age and yields of wheat and corn in South Dakota during each year between 1900 

 and 1909 inclusive, are followed by directions for wheat production in South 

 Dakota. From the work done it appears that Turkey Red is one of the best 

 varieties to plant. A test of fanned and uufanned seed of 3 varieties resulted 

 in an average advantage of 1.43 bu. per acre in yield obtained from the fanned 

 seed. Red Fife averaged 18.3 bu. per acre from 1905-10, excelling 13 other 

 spring wheats, but early Java averaged 18.5 for 1909-10. In a test of 26 

 varieties of durum wheat Arnautka averaged 23.2 bu. per acre during 1901-2 

 and 1904-10, being excelled only by Arnautka 1,-590, Arnautka 1,530, and 

 Taganro 1,570, which were tested during briefer periods. Descriptions of a 

 number of varieties are followed by directions for treating seed for smut. 



Garden and field seeds sold in Connecticut in 1910-11, Mary H. Jaggkr and 

 E. H. Jenkins {Connecticut State Sta. Rpt. 1909-10, pt. 12, pp. 805-818),— In- 

 structions for sampling seeds are followed by notes on the results of tests of 

 alfalfa, clover, and grass seeds. A table shows in detail the results of each test 

 made. The data presented includes the name of the dealer from whom seeds 

 were secured, the weight per thousand seeds, the purity, germination, and 

 viability percentages, and the percentage of inert matter and of foreign matter 

 present. 



Among 5 varieties of onions tested the minimum and maximum results were 

 obtained from White Portugal and Wethersfield Red, of which 70.82 and 79.07 per 

 cent respectively, sprouted. Of Connecticut and California grown seed stated to 

 be less than 1 year old 74.72 and 88.18 per cent respectively, sprouted. In the
