336 EXPERIMENT STATION EECORD. 



Contributions on the breeding of peas and field beans, G. Fbolich {Filh- 

 ling's Landtv. Ztg., 58 (1909), No. 20, pp. 7J3-726).—The methods followed are 

 briefly described and the work discussed with special reference to the number 

 of stems and number of pods per plant. The results of variety tests are also 

 stated. 



The bean plants having 2 or 3 stems excelled the one-stemmed plnnts in plant 

 weight, seed weight, seed number, and number of pods, but the number of seeds 

 per pod was approximately equal. The one-stemmed plants had the greatest 

 height. No correlation was observed between branching tendency and the 

 ability to produce a large yield. 



Correlation between the weight and percentage protein content of barley- 

 kernels, E. Sperling {lUus. Lanclw. Ztg., 30 (1910), No. 19, pp. 115, 176). — 

 The average kernel weight and percentage protein content of a large number of 

 barley samples are presented in tabular form. No regularity of correlation 

 between tbe two characters could be observed by the author. 



The separation of seed barley by the specific gravity method, H. B. Deer 

 (U. S. Dept. Agr., Bur. Plant Indus. Circ. 62, pp. 6, fig. 1). — The specific grav- 

 ity method of separating seed barley consists in immersing the seed in water, 

 stirring it thoroughly, skimming off and rejecting that which floats, and care- 

 fully drying the selected seed. It may be combined with the treatment for smut. 

 A brief bibliograpby and review of the literature of the subject is given. 



A more profitable corn-planting method, C. P. Hartley ( U. S. Dept. Agr., 

 Farmers' Bui. JjOO, pp. l.'i, figs. 5). — This bulletin compares tbe advantages of 

 drilling and ordinai-y checking of corn with tbose of "kernel-spaced checking" 

 or checking in which the hill is one of 4 stalks, each placed at 1 of the corners 

 of a 5-inch or larger square. In tests of tbis method conducted at Round Hill 

 and McLean, Ya., and at Piketon, Ohio, on different soils and with different 

 types of corn, gains of of, 5, and 4 per cent, respectively, over tbe yield secured 

 by the ordinary metbod were obtained. 



The autbor suggests tbe manufacture of check rowers with 2 shoes for each 

 corn row and a separate dropping tube for each kernel of a hill, and adjustable 

 in point of number of kernels dropped and the spacing between the kernels of a 

 hill. It is pointed out that the increased yield due to such kernel spacing 

 should be clear gain, as a properly constructed check rower should drop the seed 

 in separate places as rapidly and cheaply as the present check rower does its 

 work. No difficulty was encountered in cultivating corn planted in this manner 

 in rows 3^ ft. apart. Three-horse 2-row cultivators could have been used to as 

 good advantage as in the usual method of checking, even though tbe kernels 

 had been spaced 6 or 8 in. apart. At McLean, Va., and Piketon, Ohio, it was 

 noted that kernel-spaced rows were less subject to damage by winds than those 

 checked in tbe ordinary manner. 



Variety work with cotton and notes on selection, R. J. H. DeLoach (Bui. 

 Univ. Ga., No. 115, pp. 8, figs. 3). — In a test of 27 varieties. Cook Impi'oved 

 and Cleveland Big Boll produced 557.6 and 518.4 lbs. per acre of lint cotton 

 respectively. Classifications of varieties are given on the basis of number of 

 bolls to produce 1 lb. of lint, earliness, number of seed per pound, and lint 

 percentage, together with notes on selection. 



Suggestions on cotton cultivation and fertilization, R. J. H. DeLoach and 

 A. M. SouLE (Bill. Univ. Ga., No. 118, pp. 8). — This bulletin gives directions for 

 cotton production in Georgia. A score card suggests points to be observed In 

 selecting plants for seed. 



Distribution of cotton seed in 1910, D. N. Shoemaker (U. 8. Dept. Agr., 

 Bur. Plant Indus. Doe. 535, pp. 13, figs. //). — Two methods of seed selection are 

 discussed and the qualities to be sought in cotton improvement and methods
