weight per bushel, and percentage of sound and damaged oats are presented in 

 tabular form and briefly discussed. 



Bleaching weather-stained, discolored, and damaged oats is said to give them 

 the appearance of natural oats of good quality and to improve slightly the ap- 

 pearance of badly bin-burned and ground-damaged oats. In practically every 

 case the viability of the oats was materially reduced by the bleaching procc- 

 the greatest reduction being observed in a sample which germinated 97.5 per 

 cent before treatment as compared with 9.5 per cent after treatment. The 

 methods employed were found to be practically uniform throughout the oat- 

 bleaching section. The character of the harvest season is said to have a direct 

 influence upon the subsequent handling of the crop, oats harvested in a dry 

 season rarely showing any damage and hence seldom being bleached. 



[Peanut culture in southern France], A. Morel (Compt. Rend. Acad. Agr. 

 France, 3 (1917), No. J f 0, pp. 1131-1136). — Peanut growing in the Department of 

 Gironde is briefly described. Reviewing results obtained from field tests, it 

 is found that the highest yields of mature peanuts and of vine were secured 

 from plantings made on or before June 1, and at n Beeding rate of from 25 to 

 30 kg. per hectare (from 22.2 to 26.7 lbs. per acre) with the plants spaced 

 from 50 to 60 cm. (from 19.7 to 23.0 in.) apart in all directions. 



The book of the potato, T. W. Sanders (London: W. II. if L. Collingridgc, S. 

 ed., rev.. [1911]. pp. 110. pis. 11. figs. 30).— This is the third edition of a work 

 previously noted (E. S. R., 17. p. 132), revised and brought up to date in re- 

 gard to cultural and manurial methods, the treatment of disease and insect 

 pests, and the selection of suitable varieties. 



Grow more rape, J. M. BwABD and W. R. HECHLEB (loira Sta. Circ. 53 

 (1918), pp. 9-12, figs. / 1.— The value of rape as pasturage for sheep and hogs is 

 indicated, and an increased acreage is recommended. Methods employed in 

 growing the crop are briefly described. 



Sudan grass, H. L. Stewart and L. Foster i V. w Mexico 8ta. Bui. Ill (1918), 

 pp. 3-13, figs. 2). — Pate, rate, and method of seeding tests and pasture experi- 

 ments with Sudan grass made during the period 1915 to 1917, inclusive, are 

 briefly described, and the suitability of the crop for both hay and pasture in 

 the irrigated valleys of New Mexico discussed. 



Yields of from 3 to 7} tons of hay per acre have been obtained under irriga- 

 tion. Early plantings (the latter pari of April) gave the highest yields, while 

 broadcasting seed at the rate of from 20 to 25 lbs. per acre was found best. 

 Slightly higher yields were obtained from seeding made in 32-in. rows, but 

 the resulting bay crop was of inferior quality. 



Pasture tests indicated that Sudan grass will make a good supplementary 

 pasture for dairy cows during the latter part of the summer. 



Sugar beet seed [in France], E. Saii.i.ard (Compt- Rejld. Acad. Soi, [Parte], 

 165 (1911). No. 16. pp. 508-510).— Stating that approximately 5,000.000 kg. 

 (about 5,.*i00 tons) of sugar beet seed was used annually in France before the 

 w;ir and that approximately four-fifths of this seed was of foreign origin, the 

 author briefly reviews experiments begun in 1904 to compare French-grown 

 seed with German-grown seed. During the war the seed was practically all of 

 Russian .and French origin. For the 10-year period of 1904 to 1913, inclusive, 

 weekly analyses of the beets grown in the comparative tests were made at 

 14 sugar beet factories beginning about August 1. In 19<>r. French seed pro- 

 duced approximately 140 Eg. per hectare (12."» lbs. per acre) less sugar than 

 German seed and the beets showed approximately 0.9 per cent less BUCTOG 

 At the present time it is claimed that production is practically the same, al- 

 though beets from French seed analyze from 0.3 to 0.4 per cent less sucr. 

 than those from German seed. Further observations were made of the sugar
