446 EXPERIMENT STATION RECORD. 



T-welve years of sug-ar beet tests in the United States {Beet Sugar n<tz., 3 

 {1901), No. 2, pp. 29, 30). — A summary of the results of work witli sugar beets at the 

 agricultural experiment stations of the United States during the past 12 years. 



Sugar bsets, 1891-1900, J. T. Willard and R. W. Clothier {Kum^dx Sta. 

 Bui. 10 J, pp. 275-286). — The results of experiments with sugar beets in 1900, together 

 with the analyses of samples containing over 14 per cent of sugar in the juice and 

 representing all previous sugar-beet work within the State in connection with the 

 station, are tabulated. Theaverage sugar content of the juice in 1900 was 9.89 per cent, 

 with an average purity coethcient of 72.7. In the opinion of the authors only the 

 western part of the State, where the natural rainfall is entirely insufficient and the 

 moisture required by the crop is supplied and regulated Ijy irrigation, offers real 

 climatic advantages for sugar-beet production. 



Experiments in the culture of the sugar beet in Nebraska, II. H. Nich- 

 oLsoxandT. L. Lyox {Xebrti.'tka Sla. Rpt. 1900, pp. ^^9-48). — The results here reported 

 at some length have been noted from a previous bulletin (E. S. R., 12, p. 846). 



The sugar beet in North Carolina, W. A. Withers {North Carolina Sta. Bui. 

 180, pp. 91-106, maps 2). — This bulletin gives the history of experimental sugar-beet 

 culture in the State, and reports tiie results of cooperative culture experiments con- 

 ducted by the station in 1898 and 1899. The sample beets from several counties 

 showed over 14 per cent of sugar. The opinion is that while the State in general is 

 not well adapted to sugar-beet culture, there are certain sections in the western part 

 of the State where the profitable culture of the sugar beet is feasible. 



Regeneration of the seed beet, F. BrsAK {Dent. Laudw. Presse, 28 {1901) , No. 22, 

 pp. 183, 184, fg-1. 3). — A report on observations in beet seed culture. The author 

 concludes from his observations and those of other investigators that the beet which 

 yields seed during several vegetative periods develops each year one or more branch 

 roots which contain the reserve material, and that the life of these roots depends 

 largely upon the successful wintering of the adventitious buds. 



The sugar industry of Louisiana, R. Dvkers ( Tradesrnav, 44 {1901), No. 9 {22 

 Ann. ), pp. 144-146) . — A general article on the culture of sugar cane and the present 

 condition of the sugar industry in the State. 



Culture of sugar cane {Bol. Ayr. Mlii. e Lid. [Mh-ico], 10 {1900), Atas. 5, p. 39, 

 pis. 2; 6, p. 39; 7, p. 64) • — This article treats of the history, classification, composi- 

 tion, and culture of sugar cane. 



Sugar production in Mexico {Mitt. Deut. Landw. GeselL, 16 {1901), Sup. to No. 

 10, pp. 6.5-72). — A description of the sugar industry from an agricultural standpoint 

 in different Mexican States. 



Seedling canes {Sucr. Indig. et Colonude, 57 {1901), No. 11, pp. 340-342). — The 

 degeneration of varieties of sugar cane during the last century is considered in this 

 article and circumstances are described which indicate that the borer, so destructive 

 to the crop, first appeared in Guadeloupe in 1785. 



Experiments on the manuring of swedes ( County Councils Cumherland, Durham, 

 and Nurthmnherlund, Tech. Education, R]>t. 9 {1900), pp. 9-20). — Cooperative experi- 

 ments were made to determine the effects of commercial fertilizers used alone and 

 with barnyard manure, and further, to test the soils on which the work was carried 

 out. The average results show that where 2^ cwt. of slag, j cwt. of nitrate of soda, 

 f cwt. of sulphate of ammonia, and 2 cwt. of kainit were applied with 12 tons of 

 barnyard manure, the increase in crop just paid for the commercial fertilizers. Con- 

 sidering the results of rotation experiments, it is believed that the effects of commer- 

 cial fertilizers on subsequent crops would give a profit. The nitrogenous fertilizers 

 produced the greatest increase in crop. 



Sweet potato, F. S. Shiver {South Carolina Sta. Bui. 63, pp. 37). — This bulletin 

 sets forth the results of 3 different lines of observations, namely, the effect of fertiliz- 

 ing with different forms of potash on the starch content of the sweet potato, the effect
