Cleveland to be the heaviest yielder, with 1,055 lbs. of lint cotton per acre, 

 which was 37 per cent of the seed cotton yield. Seventy-six bolls of this 

 variety made 1 lb. of seed cotton. 



Of 19 varieties of corn Weekley Improved yielded 51.79 bu. per acre, showing 

 84 per cent of grain on the ear and 144 ears per bushel. 



Local fertilizer experiments with cotton in south Alabama in 1913, J. F. 

 DuGGAR, J. T. Williamson, and L. J, Hawley (Alabama Col. Sta. Bui. 174 

 (1913), pp. 147-192). — Continuing previous work (E. S. R., 29, p. 335), the 

 results showed that in 10 out of 23 conclusive experiments, cotton-seed meal 

 was more effective than either acid phosphate or kainit In 65 per cent of the 

 experiments, acid phosphate was needed to a greater or less extent, while in 70 

 per cent kainit was needed to a greater or less extent. 



The data also show that, as a rule, the complete fertilizers were more profit- 

 able than fertilizers applied singly or in pairs. In general it was more effective 

 in all 3 years to apply 200 lbs. of kainit in a complete fertilizer than to use 

 100 lbs., although in 1911 a larger profit was made when 100 lbs, of kainit was 

 used. The average of the conclusive experiments in both 1912 and 1913 

 showed that 200 lbs. of cotton-seed meal applied before planting was prac- 

 tically equal in effect to 100 lbs, of nitrate of soda applied after the plants 

 were 6 in. high.

Color correlation in cowpeas, W, J. Spillman (Science, n. ser., 38 (1913), 

 No. 974, P' 302). — This gives some observations made in genetic investigations 

 with cowpeas. 



" The flower color, which is due to an anthocyan. and the anthocyan in 

 stems and leaves are dependent on 2 Mendelian color factors, one of which, 

 apparently an enzym, is the general factor for color in the seed coat of the 

 cowpea. The other is the special factor for black, which when added to a 

 variety having coffee-colored seeds converts the seed color to black. [The 

 author has] found 3 independent Mendelian factors for ' eye ' in the cowpea 

 which, singly and together, give 5 distinct types of 'eye.' One of these 

 factors, which gives the type of * eye ' which [he has] designated the narrow 

 • eye ' also has the effect of inhibiting the development of anthocyan in the 

 flowers, though it permits its development in stems and leaves." 



Flax experiments, 1911 (Dept. Agr. and Tech. Inst7\ Ireland Jour., 13 (1913), 

 No. 3, pp. 515-534). — This article summarizes the results of the flax experi- 

 mental work in Ireland from 1905 to 1910 inclusive, and reports the continua- 

 tion of the work for 1911 which was carried on at 10 centers. 



Muriate of potash applied at the rate of 1 cwt. per acre increased the 

 yield of straw and fiber to a profitable extent, and the percentage of scutched 

 flax was higher and of better quality than that from the unmanured plats. 

 The combination of muriate of potash and sulphate of ammonia also gave 

 increased yields, but at less profit than the muriate of potash alone. The 

 addition of steamed bone flour did not give satisfactory results in either
