plants each of 0. fulgida, 0, spinosior, O. arbiisciiJa, O. discata, O. linquwformis, 

 aud Opuntia sp. Experiments were contained witli Andropogon torreyanus,

[Experiments with, sugar beets and cotton], R. W. Clothier {Arizona Uta. 

 Rpt. 1909, pp. 563, 56i).^A good stand of sugar beets was secured but nearly all 

 were killed by root rot. The plants analyzed varied from 0.5 to 1.75 lbs. in 

 weight, from 13 to 18 per cent of sugar in the juice, and from 77 to 83.3 per cent 

 in purity. All the cotton seed planted was 2 years old, but it produced a perfect 

 stand except in the case of Roger Big Boll. Cook Improved produced a maxi- 

 mum yield of 1,734 lbs. of seed cotton per acre. It required 2.7 hours longer to 

 pick 100 lbs. of Egyptian (Mitafifi) than any other variety. 



Report on oat and barley experiments, 1909, R. B. Greig {Aberdeen and 

 No. of Scot. Col. Agr. Leaflet 10, pp. 6). — In 1901 a mixture of 5 bu. of Waverley 

 oats with 6 bu. each of Wide Awake, Siberian, and Thousand Dollar varieties 

 was sown. During each succeeding year the produce has given a heavy uniform 

 crop. At 8 centers the Major variety produced the highest average yield of 7G 

 bu. among 6 varieties tested. Among S varieties of barley tested at 8 different 

 centers Invincible produced the highest average yield. 47 bu. of dressed grain per 

 acre, as well as a higher yield of straw than most other varieties. 



Meadows and pastures, T. F. Hunt {Pennsylvania Sta. Bui. 101, pp. 3-16, 

 figs. 3). — This is an address delivered before the Pennsylvania State Board of 

 Agriculture and before the Pennsylvania Live Stock Breeders' Association, and 

 based largely on data noted from other sources (E. S. R., 21, pp. 133, 220; 23, 

 p. 138). 



A plat unfertilized for 28 years yielded in 1909, 1,21G lbs. of hay, as compared 

 with 4,496 lbs. following an application of phosphorus and kainit. Little effect 

 followed the application of 320 lbs. land plaster. On other plats 2 tons of quick- 

 lime added once in 4 years was compared with 6 tons of manure added once in 

 2 years. A check plat yielded 1,040 lbs. of hay in 1909 and a total of 11,663 lbs. 

 of all products during 1882-1906. The corresponding figures for the limed plats 

 were 1,880 and 11,632 lbs., for the manured plat 4,008 and 17,383 lbs., and for a 

 . plat both limed and manured 5,784 and 18,016 lbs. per acre. 



Cooperative experiments — grasses {Ag?: Jour. Cape Good Hope, 36 {1910), 

 No. 6, pp. 675-690). — These pages report the results of cooperative experiments 

 with grasses, clovers, and alfalfa on u large number of farms. 



Canada bluegrass: Its culture and uses, R. A. Oakley {U. S. Dept. Agr., 

 Farmers' Bui. 1)02, pp. 20, figs. 7). — This bulletin describes Canada bluegrass 

 and discusses its uses as a pasture grass, hay, aud soil binder for lawns and on 

 scab lands. Suggestions are made for harvesting, thrashing, and cleaning the 

 seed and for obtaining a stand and breaking up old sod. 



Suggestions on corn breeding, P. O. Vanatter {Bnl. Univ. Ga., No. 117, pp. 

 31, figs. 8). — Four varieties each of western and southern corn averaged, respec- 

 tively, 52.67 and 63.94 bu. per acre and 56.5 and 88.25 per cent in the germina- 

 tion tests. In the case of 15 plants of Whatley Prolific in which the ears 

 weighed more than the barren stalks the ratio was 1 : 0.51, while with 4 other 

 plants the ratio was 1 : 1.37. Similar ratios of the Red Cob variety were 

 1 : 0.62 in case of 8 plants and 1 : 1.95 in case of 12 plants. The fodder is not 

 so good and the grain does not germinate as well in case of the plant in which 

 the weight of grain is less than that of the stalk. Tables show the date of 

 ripening, weight of ear in ounces, weight of stalk at different dates, ratio of 

 ear to stalk, and percentage of germination for 20 stalks each of Whatley Pro- 

 lific and Marlboro Prolific.
