636 EXPERIMENT STATION RECORD. 



ton tintwins In Nyasalaiul decreased from 22,000 acres in l!>Or) to 7,000 in 1907, 

 as it has been found that the growing season is too short for maturing the 

 Egyptian varieties at the elevation of 2.500 ft. The average lint percentage of 

 upland cotton is now 27 per cent. , Means of improving this and other features 

 of the cottons grown are discussed, together with their cultivation, climatic 

 requirements, and the tune and metliods of i)lanting, topping and harvesting, 

 in both uplands and lowlands. Notes are given on insect pests. 



Cotton facts, A. B. Sheppekson iXnr York, 1909, pp. IX+18(), fig. 1, map 

 1). — A review of the cotton season of 1908-9 and of the prospects for the sea- 

 son of 1909-10 is followed by crop and other statistics for the United States 

 and other countries. Meteorological data and information of general interest 

 to cotton growers are included. 



Cotton, the greatest of cash crops, S. A. Knapp {U. ki. Dept. Agr., Office 

 Hcc. Circ. 3.>. pp. ID). — In this address, delivered at Greenville, Miss., January 

 17, 1910, the past and present world demand for cotton is outlined and the posi- 

 tion of the United States in supplying the demand is discussed. The present 

 status of cotton growing in the United States is set forth with special refer- 

 ence to boll weevil conditions. 



Broom millet, G. Marks (Dept. Agr. N. *S'. Wales, Farmers' Bui. 20, pp. 20, 

 figs. 11). — Discussions of the trade and fertility requirements and of the mar- 

 keting and botany of broom millet are followed by directions for producing, 

 harvesting and baling the crop, and for seed selection. 



Oats, E. G. Montgomery (Nebraska aS/a. BuI. 113, pp. 3-16. fig. I). — Tabu- 

 lated data present the results of a test of 12 varieties of oats and indicate the 

 yield per acre, susceptibility to rust, date of heading, and date of harvesting 

 of each of the varieties. 



The earlier varieties have given, during the past 5 or 6 years, an average 

 yield 14 bu. per acre greater than that of the later varieties. 



Sowing at the rate af S pk. per acre gave the best results with drilled Kher- 

 son oats and 10 pk. when the oats were sown broadcast. Cultivation gave an 

 increased yield of 4.8 bu. per acre of drilled oats but a decreased yield of 

 broadcast oats. When the rainfall is more than normal, damage is done by 

 cultivating either oats or wheat but when precipitation before seeding has 

 been meager, cultivation of grain produces good results by conserving moisture 

 and removing a part of the stand. 



Owing to the difference in weight and volume of kernel, 8 pk. of Kherson, 

 14 pk. of Dun, and 19 pk. of New Reliance oats produced the same number of 

 plants per acre. It is noted that there was a strong tendency for thin seedings 

 to tiller enough to bring the stand up to normal, or about 1,700,000 stems per 

 acre. 



Improvements in paddy cultivation on the home farm at Sivagiri, Tinne- 

 velly district, J. M. Lonsdale (Dept. Agr. Madras BtiL 61, pp. 8). — The opera- 

 tions of the station are outlined and the value of the various crops of the 

 region discussed. 



A number of varieties of paddy have been introduced from northern India 

 and elsewhere. Swarnavari and Banku. which are brought from regions 

 where the atmosphere is exceedingly hot and dry and irrigation water is never 

 abundant, are particularly good in quality, yield, early maturity and drought 

 resistance, but lose these characteristics when grown under less exacting cir- 

 cumstances, so that it is necessary to obtain new seed every 5 or 6 years. Seed 

 selection is being carried on for the improvement of the introduced varieties, 

 and a brief statement of the more important points with regard to 9 of these 

 varieties is given.
