FIELD CKOPS. 639 



The authors have shown that the cotton grown throughout the provinces 

 consists of a mixture of types. The flowers are of 3 colors clue to 2 color char- 

 acters, yellow and red. " When both colors are present the flower has the full 

 red color ; when red is present and yellow is absent the flower is pink, while if 

 yellow is present and the red absent the flower is yellow." 



The plant sought by the authors in their work must be ripening fruit by the 

 beginning of October if sown at the beginning of the rains, thus having a vege- 

 tMtive period of from 70 to 80 days. It must flower early and be a vigorous 

 heavy yielder. with a fine, long, silky lint. A red flower is an important although 

 secondary requirement, as it is an easily detected feature and aids in disclosing 

 the mixture of impure strains. Crosses between Nurma and a short, staple, 

 silky Bani, and between Nurma and a white-flowered Desi have been relied on 

 for i)ractical results in earlier experiments which are discussed. 



Sugg'estions for cotton growers, R. H. B. Dickson (Rhodesia Agr. Jour., 8 

 (1911), No. -'i, pp. 563-583, pi. 1). — A brief i-eview of the world's cotton supply 

 and demand is followed by itemized slatements of the cost of producing and 

 marketing the crop in the Transvaal, and an itemized statement of the average 

 cost per acre on 3,325 plantations in the southern part of the United States. 

 The total cost per acre given is £3 4s. 6d. 



Cotton cultivation: Prospects in Transvaal, T. A. J. Place (Agt: Jour. 

 Union So. Africa, 1 (1911), Xo. 1, pp. J8-6".}. pis. 2). — The author presents esti- 

 mates of the cost of production and the returns per acre of cotton, indicating a 

 profit of £4 Ss. per acre. He states that at the Barberton experiment station 

 Doughty Big Boll, Black Rattler, and Cook Long Staple yielded 1,292, 1,272, 

 and ,1.224 lbs. of seed cotton per acre, respectively, while at the Tzaneen sta- 

 tion in the Zoutpansberg district equally satisfactory results have been obtained. 



Cotton growing in German East Africa, L. Hamilton (United Empire [Qt. 

 Brit.], n. ser., 2 (1911), No. 6, pp. -'iJ0--'il5, map 1). — This is a discussion of the 

 possibilities of avoiding the "American cotton monopoly " by the development 

 of cotton growing in German colonies. 



Some problems connected with the introduction and cultivation of exotic 

 cottons in Nyasaland, J. S. J. MoCall (Nyasaland Dept. Agr. Bui. 1, 1911, pp. 

 8). — A statement of the climate, insect pests, and other local conditions with 

 special reference to cotton growing in Nyasaland accompany suggestions on 

 the choice of seed. 



Field pea production in Washington, M. W. Evans (Washington Sta. Bui. 

 99, pp. 4-22, figs. 4). — In this report of investigations in cooperation with the 

 Bureau of Plant Industry of this Department, statements of some cultural and 

 other characteristics of 6 varieties are followed by directions for growing, har- 

 A'esting, thrashing, and utilizing field peas in Washington. 



In a rate of seeding test conducted during the very dry summer of 1910 the 

 maximum yield of Kaiser followed seeding at the rate of 127 lbs. per acre, but 

 in case of Bangalia 73 lbs. appeared to be the best rate. 



Rice, J. Kenny (In The Coconut and Rice. Madras, 1910, pp. 25-58). — In a 

 test of 7 different fertilizer mixtures applied at various rates applications of 

 (1) 6 maunds (493 lbs.) of bone meal, (2) 3 maunds of bone meal, and (3) 100 

 maunds of cow dung were followed by yields of 3,962, 3,663, and 3,556 lbs. of 

 grain per acre. These were 12-year averages for the period ended in 1903. 

 Tables state the results of other fertilizer tests with rice.

 fiber are followed by statements of results obtained at the experiment station.
