Rice culture, G. d'Utra (Bol. Agr. Sao Paulo, 2. ser., 1901, No. 5, ))p. 281-391).— 

 A report on culture experiments with several varieties of rice. 



The rice industry in Queensland, F. W. Peek (Queensland Agr. Juur., 9 (1901), 

 No. ■},]>]'. 414, 41o). — This article discusses the soil and climatic conditions of Queens- 

 land in their relation to rice culture. 



Saltloushes, R. W. Peacock (Agr. Gaz. New South Wales, 13 (1901), No. 7, 

 pp. 791-793) . — General notes on tlie culture of saltbushes, with brief descriptions of 

 several species. 



The sugar beet in Indiana, H. A. Huston (Indiana Sta. Rpt. 1901, pp. 89-106). — 

 This report summarizes the sugar-beet tests in Indiana from 1888 to 1900. The con- 

 ditions necessary for the success of a beet-sugar factory and the requirements for the 

 profitable culture of the sugar beet are discussed. Meteorological data for different 

 sections of the State are tabulated, and the average sugar content and purity of the 

 samples grown in different countries are given, with brief comments on the results. 



Chemical changes in the composition of the sugar beet during the period 

 of ripening, K. Andrlik ( leslnik III Sjezdu Ceske. Prir. Lek Praze, 1901, p. 310; ubs. in 

 Chem. Ztg., 25 (1901), No. 70, 256). — The variations in the sugars and other organic 

 substances and the ash constituents during the ripening period of the sugar beet are 

 shown in tables. 



The growth of the German sugar industry from 1850 to 1900, E. O. von 

 LiPPMANN (l)k Enlvnckelung der deutschen Zuckmndustrie von 1850 his 1900. Leqjsic: 

 Hesse & Becker, 1900, pp. 341) . — A treatise published on the occasion of the fiftieth 

 anniversary of the German Association for Sugar Industry. 



Work of the Hawaiian [Sugar Planters'] Experiment Station, E. E. Blouin 

 (Honolulu: Hawaiian Gazette Co., 1901, pp. 25). — Fertilizer, culture, and irrigation 

 experiments are reported. Fertilizers were applied in different quantities antl vari- 

 ous combinations to a rattoon crop of Lahaina and Rose Bamboo varieties of sugar 

 cane. The quantity of nitrogen used varied from 179 to 227 lbs. per acre, and the 

 phosphoric acid from 145 to 194 lbs. The quantity of potash was kept constant at 

 255 lbs. per acre. One-third of the fertilizer application was applied at each of 3 

 different times, July 26 and October 10, 1899, and ]March 29, 1900. The highest 

 average yields of sugar were obtained from the use of nitrogen and potash. The 

 lowest average yield was produced by the unfertilized plats. Similar i-esults were 

 obtained the year liefore with a crop of plant cane. Taking the results with each 

 variety of cane separately, the Rose Bamboo plant which received nitrogen and phos- 

 phoric acid gave the highest yield in weight of cane and amount of sugar. Nitrogen 

 and potash applied together in this case gave next to the lowest yield. With Lahaina 

 cane the nitrogen and potash gave the highest yield, both in weight of cane and 

 sugar. Where these elements were used singly they produced but a small increase, 

 but in comVjination the results were very pronounced. 



Cane trasli used as a fertilizer increased the yield of both cane and sugar. A test 

 was also made of planting cane in rows 4, 5, 6, and 8 ft. apart, with the result that 

 the plat Avith the rows 5 ft. apart produced about 4 tons of sugar more per acre than 

 any other plat, followed by the 4, 6, and 8 ft. rows in the order given. The 5 ft. 

 rows also gave a juice of higher purity than any of the other plats. 



Irrigation experiments were carried on with special attention to the time of apply- 

 ing the water and the quantity used. Water was applied at the rate of 1, 2, and 3 

 in. per week, 2 in. every 2 weeks, and 3 in. every 3 weeks. The results were decid- 

 edly in favor of applying 2 in. of water weekly. The application of 2 in. every 2 

 weeks produced a good yield of cane, but with a markedly low sugar content which 

 brought the yield of sugar below that of other plats receiving the same amount of 

 water. The results indicate that the intervals between irrigation sirould not be more 

 than one week.
