FIELD CROPS. 349 



as the heads are formed. The common practice i.s to cut for silage when the seed 

 is in the ' dough.' 



"The forage contains an excess of fat-forming substances and should be fed in 

 connection with foods rich in muscle-making materials. The seed is usually fed 

 witli the stems and leaves. Thrashed seed should be crushed or ground and mixed 

 with wheat bran, oats, or other nitrogenous foods." 



Sugar beets, N. E. Wilsox {Nevada Sta. Bui. 32, pp. 47). — This bulletin is a 

 review of the beet experiments conducted at the station since 1891. Part of this 

 work lias been reported in previous bulletins (E. S. R., 6, 411). 



Sucrose content and purity of the several varieties harvested at different dates 

 from August 1*7 to October 29; gain or loss in sucrose, solids, and purity between 

 the dates of harvesting; a summary of licet analyses made at the station from 1891 

 to 1896; and daily meteorological conditions during the harvesting period are given 

 in tables.

 Bnihant-Hainaut, 1897, No. 10). 



The tobacco industry in Germany, G. Lewinstein ( Volksivirthschafiliche Zeit- 

 fragen, IS (1897), Nos. 6-7, pp. 69). — The development of the industry is outlined and 

 the varieties of tobacco used are described.

Field experiments at Ghent, Belgium, P. r>E Caluwe (Expose Cult. Fxper. Jard. 

 Hand. 1895-96, pp. 106, pis. 3). — These experiments include variety and fertilizer 

 tests with rye, wheat, barley, maize, legumes, chicory, and potatoes. Fertilizer 

 experiments were made with beets, sugar beets, turnips, and grasses. Several experi- 

 ments with phosphatic and nitrogenous fertilizers are reported. Meteorological 

 observations for the whole year are giveu. 



In the experiments with oats and barley the seed was sorted into very large, large, 

 and small grains. The difference in seed had no effect on the yield of Ilanua barley, 

 but with the Chevalier variety the small seed produced the most grain. With oats 

 the very large seed produced a little the largest yields. 



Field and other experiments at Rothamsted, Sir J. B. Lawes (Mem. Rothamsted 

 Expts., 1897, pp. 111). — This is the fifty-fourth annual memoranda of the origin, plan, 

 and results of the experiments conducted on the farm and in the laboratory at 

 Rothamsted, England, being a report to the Lawes Agricultural Trust Committee. 



Experiments on pasture, 1896 (Agr. Students' Gaz., 8 (1897), No. 4, pp. 109-111).— 

 Fertilizer experiments in which the same manures have been applied to a number of 

 the plats for 10 years in succession. The results are given in tables. 



Haying tools and hay making, F. E. Emery (Arkansas Sta. Iipt. 1896, pp. 63-74, 

 figs. 24).— A reprint from Bulletin 125 of the station (E. S. R., 8, p. 307). 



The influence of the proportion of fertilizing elements on the yield, M. J. 

 Raulin (Ann. Soc. Agr. Sci. et Ind. Lyon, 7. ser., 4 (1896), pp. 302-309). 



Rotations and seasons, G. Heuze (Jour. Agr. Prat., 61 (1897), II, No. 34, pp. 308, 

 309). — A popular article outlining 3 and 6 year rotations. 



Manual of farm crops, P. de Vuyst (Manuel des cultures spe'ciales. Paris: O. Doin, 

 1897, pp. 264, figs. 29). — A practical manual treating of the culture of root crops, cere- 

 als, and forage crops; the methods and values of rotations, and the preparation of 

 meadows. The author's endeavor has been to make the book practical and to point 

 out the benefits which can be derived from the application of theories to practice. 

 With this end in view, matters of a purely scientific interest have been avoided, but 

 tin discussion of each subject is based upon the opinions and numerous experiences 

 of recognized scientific authorities, including the author. 



The subjects of manures and varieties are given prominence, as they are considered 

 the most important from a practical point of view. For the benefit of all, and 

 students especially, the subjects are treated in a uniformly methodical manner.
