234 EXPERIMENT STATION RECORD. 



siiiuly loam soils yielded bigber percentages of their total cotton crop thau 

 the red clay soils, whether fertilized or unfertilized. 



On sandy and sandy loam soils heavy and medium heavy phosphoric acid 

 fertilization with normal amounts of other plant foods produced the largest 

 percentages of the seed cotton open at the first picking. Normal fertilization 

 yielded a larger percentage of the cotton open at the first picking than high 

 nitrogen applications on sandy and red clay soils, while potash applications 

 yielded still lower percentages of the total yield open at the first picking on 

 all soils studied than did the high nitrogen applications. When used with 

 commercial fertilizers air-slaked lime inci'eased the tendency to cause early 

 maturity, but when used alone the lime did not hasten maturity. 



Cultivation of broach cotton in Dbarwar, M. L. Kxjlkaeni (Dept. Agr. 

 Bombay Bui. S3, JV09, pp. 8). — In a comparative test Broach excelled Kumpta 

 cotton by 100 jjounds per acre in yield, and 8 per cent in lint percentage. 

 Its cost of cultivation was nearly one and one-third times as great, but the 

 value per acre of the yield was over one and one-third times as great. 



Hindi cotton in Egypt, O. F. Cook (U. 8. Dept. Agr., Bur. Plant Indus. Bui. 

 210, pp. 58, pis. 6). — This paper presents observations on the results of the mix- 

 ture of inferior Hindi cotton with Egyptian cotton, made during a visit to 

 the cotton-growing districts of Egypt. It deals with the importance of uni- 

 formity in Egj-ptian cotton, the character of Hindi cotton plants and their 

 lint and seed, and the characters of hybrids of Hindi and Egyptian cottons 

 and their relationships. 



The claim that Hindi cotton is all removed from the field at time of thinning 

 was disproved by the fact that obvious hybrid forms and plants of the Hindi 

 type remained in the fields, sometimes constituting more than 10 per cent of 

 the total number of plants. Although the careful hand grading and sorting 

 by cheap labor, which brings about uniformity in the Egyptian-grown cotton, is 

 not possible in the United States, the author believes that with reasonable care 

 in maintaining uniformity of type in the field it is not apparent " that the 

 American-grown Egj-ptian cotton is likely to sulfer any commercal disadvantage 

 on the ground of lack of uniformity in comparison with the Egyptian crop." 



Proceedings of the cotton-culture commission of the colonial agricultural 

 committee {Verhandl. Kolon. Wirtschaftl. Kom., 1910, No. 2, pp. GJ/, pi. 1). — 

 This report contains a collection of papers by difi'erent authors treating of the 

 cotton-culture enterprises undertaken in German East Africa. 



The possibilities of growing cotton in Togo, Uganda, and various sections in 

 German East Africa are discussed, together with the advisability of establishing 

 cotton gins and cottonseed-oil mills in certain localities. The possibilities of 

 growing and exploiting Eriodendron anfractuosum, as well as species of Calo- 

 troi)is, plants from which fiber is obtained, are briefly noted. 



Cotton growing in Ceylon (Circs, and Agr. Jour. Roy. Bot. Gard. Ceylon, 

 5 (1910), No. lit, pp. 181-200). — ^This circular points out the prospects for the 

 development of the cotton-growing industry under existing conditions in Ceylon, 

 and the possible developments which might follow fi'om either the introduction 

 of foreign capital on a large scale or a vigorous attempt on the part of the 

 Government to extend the industry. One of the principal hindrances to the 

 investment of capital in this industry is the intermittent nature of the employ- 

 ment afforded for labor of cotton cultivation, but it is believed that the culti- 

 vation of cotton would be an industry well suited for the small native capital- 

 ists, who can not afford to wait long for a return.
