Rice culture, J. Roonackeb and A. W. Drost {InsiJectic Landh. West-Indic. 

 Bui. S, 1)1). So). — This bulletiu contains a description of rice culture in Surinam. 

 Statistics of the industry are presented, the profits of rice growing given, and 

 the methods of culture discussed. 



On the continuous application of manganous chlorid in rice culture, II, 

 K. Aso {BiiL Col. Ayr. Tfjkt/o Imp. Univ., 7 (1907), No. 3, pit. Ji'i9-.'i5S),— 

 Earlier results in this line of work have been previously reported (E. S. R., 16, 

 p. 42). 



The data secured showed that liming increased the yield by 1!) per cent. The 

 manure and fertilizer application, increased by 33 per cent, gave an increase 

 of 24.8 per cent in total yield. On the manganese plats the increase was rela- 

 tively greatest when manuring conditions were the least favorable, the increase 

 in total yield being 23.5 per cent. On the limed plats the manganese gave an 

 increase of only 4.4 per cent, iu total yield. On the heavily manured plat the 

 manganese exerted no influence on the total production, but there was relatively 

 more straw produced on the check plat than on the manganese plat. In the dif- 

 ferent years the increase in total yield through the action of manganese has 

 varied from zero on the heavily manured plats of 1000 to 41.8 per cent in 1903. 



The growth of sugar beet in the midlands, J. Golding and H. B. Hutch- 

 inson {Ahs. in Jour. Soc. Chem. Indus., .iG {1907), No. 10, pp. 512, 5i5).— The 

 results of cooperative experiments with sugar beets, which are here tabulatetl 

 and discussed, indicate that complete commercial fertilizers while they maintain 

 the quality also tend to increase the total yield of sugar per acre. Of the 4 

 varieties tested, Kleinwanzleben Original gave the highest yield of sugar. 

 Stiff to medium loam soils proved most suitable to the crop, while bog soil was 

 unsuitable. The best distance for ])lantiiig in the rows was 12 to 10 in. 



The progress in the beet-sugar industry during 1906, O. Fallada (Ostcrr. 

 Chem. Ztg., 10 (1907), No. 12, pp. 161-16 'i). — This article summarizes briefly the 

 results of cultural and other agricultural experiments with sugar beets, of 

 chemical studies and analytical methods of investigation, and of improvements 

 in factory practices. 



Sugar-cane experiments in the Leeward Islands, F. Watts et at,. (Imp. 

 Drpt. Af/r. West Indies, Hiigar-Canr E.rpis. Lcrirard Ish, 1905-6, pi. 1, pp. 73). — 

 Descriptions of the varieties of sugar cane under test, together with the results 

 secured, ai-e given in tables. The experiments which have been in progress for 

 several years are conducted on 8 estates in Antigua and 8 iu St. Kitts. The 

 total area occupied in both islands is 06 acres. 



In Antigua the results with plant canes show that B.150, D.lOO, Sealy Seed- 

 ling, B.208, B.376, Queensland Creole, and B.303 stand out as especially worthy 

 of attention. Some of these canes have been mentioned in previous reports and 

 B.208 and Sealy Seedling are recommended for fairly extensive planting. D.lOO, 

 Sealy Seedling, and B.ISO have also given best results as rattoons, the first cane 

 possessing the rattooning power in a high degree. 



In St. Kitts B.254 heads the list of averages with 8,072 lbs. of sucrose per 

 acre. B.208, Sealy Seedling, D.lOO, and D.llO are recommended for trial by 

 planters. The best results as rattoons were secured from White Transparent, 

 D.05, and D.74. 



Winter wheat varieties, J. H. Barron (PennsyJvania Sta. Bui. 82, pp. 19, 

 flgs^ 8), — The results of these experiments, which have been in progress for a 

 series of years, indicate that there is no relation between straw yield and gi'ain 

 yield in wheat, that no single variety can be pointed out as the best, and that no 

 specific date for sowing wheat can be given.
