A clieniical investigation of the rice plant and of the product and by- 

 products of the rice industry, C. C. McDonnell {South Carolina Sta. Bui. 59, pp. 

 26). — This bulletin contains notes on the history and production of rice and a brief 

 description of the procasses employed in milling or cleaning the grains. Analyses of 

 21 samples, comprising parts of the plant and various by-products, were made at the 

 station and the results are given in tables. The work included analyses of the ash. 

 A table showing the average composition of some of the most important feeding stuffs, 

 taken from other sources, is presented for the purpose of comparison. The value of 

 the different parts of the rice plant and of the by-products is briefly discussed. From 

 an investigation on the percentage relation of the various parts to the entire plant, 

 the author finds that nearly one-half of the harvested crop is grain and that three- 

 fifths of the straw are leaves. The ash analyses showed a very large percentage in 

 silica, especially in the hulls. The polished grain had very little silica, but an unusu- 

 ally large percentage of phosphoric acid. All the samples showed but a small amount 

 of lime. From the results of the chemical analyses reported the quantities of fer- 

 tilizing constituents removed per acre by a crop of 35 bu. of rice and 1,800 lbs. of 

 straw are calculated and presented.

Pedigreed sorghum as a source of cane sugar, A. T. Neale {Delaware Sta. Bui. 

 61, pp. 3-24). — This bulletin gives a comparison of sugar cane, sugar beets, and sor- 

 ghum as sources of sugar, describes a method of raising sorghum, points out how its 

 value lor sugar production is determined, and discusses the machinery needed to 

 extract sorghum sugar, with estimates of its cost and suggestions as to its management. 

 The author reviews the work that has been done along this line and summarizes the 

 results obtained in Delaware, which have been partly reported in previous bulletins 

 (E. S. R., 10, p. 345; 11, p. 141). In 1898 two selections of seed were made, one 

 from stalks whose juices averaged 19.85 per cent of sugar with a purity of 83.5, the 

 stalks weighing 23 oz. each, and the other from stalks containing 19.54 per cent of 

 sugar in the juice with a purity of 83.1, the stalks averaging 18.6 oz. in weight. In 

 1899 seeds from the first selection were used on the Packard, Killen, and Neale farms, 

 and seeds from the second selection were used on the Corbit farm. This same year 

 seeds were selected on the Packard farm from 38 canes having an average sugar con- 

 tent of 16.50 per cent in the juice, a purity of 82.8, and an average weight of 24 oz. 

 per cane. These seeds were used in 1900. The results are given in the following 

 table:
