A report on the status of the tobacco industry in the different tobacco pro- 

 ducing sections of Ontario is presented. 



[Work with field crops at the Canada experimental farms in 1914], W. L. 

 Graham et ax. {Canada Expt. Farms Rpts. 1915, pp. 171-349, 355, pis. 9). — A 

 summary of the results here reported has been noted from another source (E. 

 S. R., 33, p. 830). 



Summary report of state experiment farms and cooperative experiment 

 farms, 1915, {Cheyenne, Wyo.: State Bd. Farm Comrs., 1915, pp. 70, pi. 1). — 

 Notes are given on the cultivation of tlax and cereal and forage crops at Archer, 

 Jireh, and Sheridan with only the natural rainfall, and at Lyman, Eden, and 

 Torrington with irrigation. 



Cereal experiments at the Akron field station, Akron, Colorado, G. A. Mc- 

 MuRDO {U. S. Dept. Agr. Bui. J,02 {1916), pp. 3>,, figs, ii).— This bulletin de- 

 scribes the topography, soil, and climate of the district in v.hich the field station 

 is located and presents in tabular form with discussions the results of tests 

 with 17 varieties and strains of winter wheat, 44 of spring wheat, 16 of oats, and 

 19 of barley, conducted from 1908 to 1915, inclusive. Rye, emmer, liax, proso, 

 and grain sorghums were also tested but on a smaller scale. 



Winter wheat gave better results than spring wheat and the durum wheats 

 produced higher average yields than the common spring wheats. Crimean win- 

 ter wheat produced the highest average yield, 22 bu. per acre, of any winter 

 wheat tested during the eight years and Kharkof ranked second with 21.6 bu. 

 The highest average yield of any .spring wheat obtained in the eight years, 22.4 

 bu. per acre, was produced by Pelissier, a durum wheat, followed by Velvet Don 

 with an average yield of 21.5 bu. and Arnautka with 21.1 bu. Ghirka spring 

 •wheat, of the Fife group, yielded 18.6 bu. Tests in seeding winter wheat at 

 different rates were not satisfactory but it is believed that 3 pk. per acre is the 

 best rate. Date-of-seeding tests indicated that the period from September 15 to 

 October 15 is the best for sowing winter wheat. Tests with spring wheat indi- 

 cated that sowing from 3 to 4 pk. per acre is likely to give the best yields. 



The best varieties of oats tested for the eight years were Kherson, an early 

 variety, with an average yield per acre of 44.7 bu. and Colorado No. 37, a mid- 

 season variety, with a yield of 43.9 bu. The late varieties yielded much less 

 than the early or midseason sorts. A comparison of different rates of seeding 

 of Kherson oats indicated that the best yields are obtained by sowing 4 pk. per 

 acre. 



The best varieties of barley compared during the 8-year period were Hann- 

 chen, giving an average yield of 38.7 bu., and Coast, yielding 38 bu. The 2- 

 I'owed group of barleys gave higher average yields than the 6-rowed group. 



Winter rye proved inferior in value to wheat. Winter emmer was not hardy 

 and gave an 8-year average yield of 14.2 bu., while White spring emmer aver- 

 aged 30.3 bu. per acre. Flax did not compete successfully with weeds, and most 

 varieties of grain sorghums failed to mature. The 5-year average yield of 

 Manchu Brown kaoliang was 15.4 bu. per acre, and the average yield of proso 

 for the same period was 23.1 bu. Proso seemed to be valuable mainly as a 

 catch crop. 



Cereal experiments at the Judith Basin substation, Moccasin, Montana, 

 N, C. Donaldson {U. S. Dept. Agr. Bill. 398 {1916), pp. 41, figs. J7).— This bul- 

 letin is a report on experiments with cereals conducted cooperatively since 

 1908 by the Office of Cereal Investigations of the U. S. Department of Agri- 

 culture and the Montana Experiment Station. In addition to the tabulated 

 results of experiments with wheat, oats, barley, and flax and their discussion, 

 descriptions are given of the Judith Basin, mainly with reference to topography
