532 EXPERIMENT STATION RECOED. [Vol.36 



The rate of sowing nursery beds; the age of seedlings when transplanted; 

 the influence of each, H. O. Jacobson (Philippine Agr. Rev. [English Ed.], 

 8 (1915), No. 4, PP- 213-219). — Some notes are given on studies relating to the 

 rate of seeding rice in the nursery and the age of seedlings when transplanted. 

 One cab^u (2.13 bu.) is recommended for each 1/20-hectare (0.12 of an acre) 

 seed bed. From 30 to 35 days is regarded as the most suitable age at which to 

 transplant varieties maturing within 150 days, although this will probably vary 

 with individual varieties. 



Observations on the influence of area per plant on yield of grain in rice 

 CT/lture, H. O. Jacobson (Philippine Agr. Rev. [English Ed.], 8 (1915), No. 4, 

 pp. 252-261). — This article gives the results of a number of tests with three 

 widely differing varieties to determine the effect upon yield of different spac- 

 ings of rice plants. 



The maturing period of rice was not affected by variations in spacing the 

 hills. It is concluded that under intensive cultural conditions the proper spac- 

 ing must be determined for each variety, as well as the number of seedlings per 

 hill. One seedling per hill, provided with 100 sq. cm., evidently had ample 

 space and could not utilize a greater area. As a general recommendation, 4 

 seedlings set in hills 20 by 20 cm. proved practical and beneficial. Furthermore, 

 it is pointed out that some such definite scheme of planting would result in a 

 great saving of seed. 



Errors in rice fertilizer experiments, H. O. Jacobson (Philippine Agr. Rev. 

 [English Ed.], 8 (1915), No. ^, pp. 280-282) .—This article is a criticism of some 

 fertilizer experiments with rice, pointing out errors in the management, 

 reasoning, and conclusions. 



Consumption of rice in the Philippine Islands, H. O. Jacobson (Philippine 

 Agr. Rev. [English Ed.], 8 (1915), No. 4, pp. 283-288) .—This article is a brief 

 discussion of the production and consumption of rice in the Philippines since 

 1909. It is pointed out that there is no tendency toward lessened consumption 

 of rice by the human population. 



Some observations on Chinese rice culture, H. O. Jacobson (Philippine Agr. 

 Rev. [English Ed.], 8 (1915), No. 4, pp. 296-302) .—This article consists of gen- 

 eral observations made on rice culture in China. 



Eye culture experiments with diminishing seeding and increasing nitrogen 

 fertilization at Pentkowo, Bieler (III us. Landw. Ztg., 35 (1915), No. 101, pp. 

 654, 65,5). — Comparisons were made in seeding different amounts of the same 

 variety and different varieties of rye. Later these experiments were extended 

 to include a comparison of varying amounts of nitrogenous fertilizer and 

 diffrent drill widths in sowing the seed. Some work lias also been done in 

 regard to the date of seeding. 



The results up to 1915 indicated that rye sown at the rate of 30 lbs. per 

 morgen (48 lbs. per acre), in rows 8 in. apart and with 30 lbs. of nitrogen In 

 sodium nitrate gave the highest yields. 



Triple-seeded spikelets in sorghum, A. B. Cron (Jour. Amer. Soc. Agron., 

 8 (1916), No. 4, pp. 231, 238, pi. i).— This is a report of an abnormality in in- 

 florescence of sorghums in the F2 progeny of a dwarf feterita hybrid at Araarillo. 

 Tex., in 1915. Several triple-seeded spikelets and a larger number of twin- 

 seeded spikelets in two of the panicles were the unusual characters. 



Soy-bean products and their uses, C. B. Williams (North Carolina Sta. 

 Circ. 34 (1916), pp. 1, fig. 1). — This is a general discussion of the commercial 

 uses of soy beans, especially as applied to southern conditions. The extraction 

 of the oil in this country and abroad is briefly described, together with statis- 

 tics relating to soy-bean oil importations for the five-year period ending with 

 1916, and for the year of 191G. The use of soy-beau meal as a stock feed and
