vegetative period of these newly bred varieties ranged from 92 to 00 days, the 

 average being 9G days. 



[Variety tests of corn and cotton], J. L. Burgess (Bui. N. C. Dept. Agr., 

 S2 (1911), No. 2, pp. 16). — Earlier work at some of these farms has been pre- 

 viously noted (E. S. R., 24, p. 336). 



In 1010, 21 varieties of cotton were tested on the yellow loam and silt loam 

 soils of the second bottomlands along the Roanoke and the other principal rivers 

 in eastern North Carolina. The higher j'ields secured are indicated in the 

 following table:

Results from the Karayaz Experiment Field and the demonstration 

 cotton fields in the Transcaucasian reg'ion, N. P. Tarat'mov (Kavkaz. Khoz., 

 1910, No. 6-7; al)S. in Zhur. Opytn. Agron. (Russ. Jour. Expt. Landio.), 11 

 (1910), No. 4, pp. 590-592) .-^Attev the application of about 5.000 poods of 

 manure per dessyatina (about 33f tons per acre) from 300 to 400 poods per 

 dessyatina of corn were secured as compared with from 100 to 150 poods per 

 dessyatina without fertilization. The yield of alfalfa hay was similarly raised 

 from 400 or 500 to 1,000 poods per dessyatina, and the yield of King cotton 

 from the United States from 30 to 40 or 45 poods per dessyatina. Summer 

 cereals were grown successfully, although this had been considered impos- 

 sible in the Transcaucasus, except in the case of rice. Oats yielded 100 

 poods per dessyatina while barley and summer wheat at times excelled winter 

 wheat in yield. Tests indicated that more rational methods of cultivation 

 accompanied by more moderate irrigation than locally practiced would in- 

 crease the yields of grain and cotton. 



Cotton growing- within the British Empire, J. H. Reed (Scot. Oeogr. Mag., 

 27 (1911), No. 5, pp. 242-257, pis. 2).— A lecture delivered before the Royal 

 Scottish Geographical Society in Edinburgh, on March 9, 1911, in which the 

 cotton-growing industry in the British Empire is described and reviewed to date. 



Lespedeza, or Japan clover, A. D. McNair and W. B. Mercier (17. S. Dept. 

 Agr., Farmers' Bui. Jf-'il- PP- 19, figs. 6). — This deals with the use of lespedeza 

 for pasturage, as a farm crop, as a companion crop for Bermuda grass, red 

 top, or oats, and in various rotations with corn, oats, cotton, soy beans, and 

 Spanish peanuts. Directions are given for harvesting the crop for hay or 

 seed.
