application of 200 lbs. of muriate of potash, 61 bu. after an application of 

 200 lbs. of muriate of potash and 300 lbs. acid phosphate, and 61.4 bu. after an 

 application of the last-named mixture and 100 lbs. of dried blood in addition. 

 Separate papers deal with corn insects (by J. Troop) and corn smut (by A. G. 

 Johnson). 



Annual report of the Kalimpong Demonstration Farm for the year 1909- 

 10, P. Goodwin (Ann. Rpt. Kalimpong Demon. Farm [Bengal], 1909-10, pp. 

 11+21. maps 2). — In a variety test the locally grown maizio produced yields 

 about 7 times as great as those from Jaunpur maize. On unterraced land corn 

 produced about one and a half times and buckwheat about twice as great 

 yields as were secured from terraced land. The difference is attributed to the 

 newly exi)osed subsoils which coiistitutetl half of each terrace. 



Cotton growing in the Cape Province, A. Van Ryneyeld (Agr. Jour. Union 

 So. Africa, 1 {1911), No. 3, pp. 410-412). — Four samples of Egyptian Abassi 

 cotton all showed weakness of fiber, while the Mit Afifi sample examined was 

 fairly strong. A full report for each sample is given as to weight, color, 

 strength, diameter of fibers, and commercial valuation. 



General report of the cotton commission, 1910 (Rap. Gen. Com. Coton 

 [Egypt], 1910, pp. 36, table 1, pis. 2). — This report, presented to the Egyptian 

 government, describes various factors entering into cotton culture, including 

 irrigation, precipitation, soil, degeneration, impurity, and variation in the plant, 

 crop rotations, fertilization, and the prevention of insect injury. Notes are also 

 given on the agricultural organization, the experiment stations, and the work 

 of special agricultural committees in Egypt. 



Report of field trials on the manuring of mangels, 1907-1910, T. Mil- 

 burn and R. C. Gaut (County Council Lancaster, Ed. Com., Agr. Dept., Partner's 

 Bui. 19, 1911, table 1, pp. 8). — In a 4-year test of 7 different applications of 

 natural and artificial fertilizers on various farms, the highest average yield of 

 mangels followed the use of a mixture of 15 tons of farmyard manure, 2 tons of 

 nitrate of soda, 3 cwt. superphosphate, 3 cwt. kainit, and 1 cwt. salt. The 

 nitrate of soda was applied "J as 2 top-dressings." An almost equally high 

 yield of mangels and a considerably higher profit followed the application of a 

 mixture similar in every respect except that the salt and one-half the nitrate of 

 soda were omitted. 



As a result of fertilizer tests the author concludes (1) that increasing the 

 application of farmyard manure from 15 to 25 tons did not materially increase 

 the crop; (2) that incomplete artificial fertilization was less profitable than 

 complete fertilization; (3) doubling the amount of nitrate of soda in a com- 

 plete mixture greatly reduced the profit; and (4) the use of 1 cwt. of salt gave 

 a good return. 



Millets of the genus Setaria in the Bombay Presidency and Sind, G. A. 

 Gammie (Mem. Dept. Agr. India, Bot. Ser., 4 (1911), No. 1, pp. 8, pis. 5). — 

 Descriptions and ilustrations are given of Setaria glauca and of S. italica and 

 of 3 varieties of the latter. 



Potato spraying experiments in 1910, F. G. Stewart, G. T. French, and 

 F. A. SiRRiNE (New York State Sta. Bui. 338, pp. 115-151, pi. 1, dgm. 1).— 

 This bulletin gives the results of the ninth year's work in the 10-year series 

 of potato spraying experiments begun in 1902, together with a summary for the 

 entire period. Earlier results have already been noted (E. S. R., 19, p. 447; 

 20, p. 1043 ; 23, p. 449. ) 



During 1910, 19 separate experiments were conducted along the same lines 

 as in previous years. "At Geneva 6 sprayings increased the yield 63 bu. per 

 acre and 3 sprayings increased it 22 bu. Flea beetles, early blight, late blight, 

 and rot were all factors in the experiment. The benefit from spraying was
