Investigation of the wheat of southern Russia, P. Melikov (ZJitir. Opiutn. 

 Affron., 1 {1900), No. S, pp. -.^56—267). — On the basis of analyses of different varieties 

 of wheat of the crops of the years 1885-1899, the author finds that the wheat of 

 southern Russia is rich in nitrogenous substances, the proportion of the latter varying 

 with the weather from 14 to 21.2 per cent, being highest in dry years, while in years 

 of good crops it falls to 14 per cent. — p. 1'ire.m.\x. 



Sulphate of ammonia as a top-dressing for winter wheat, Kirchxer {Dent. 

 Laudir. Presse, 28 {lUOl), Xo. 21, p. 171). — This article records the results of fertilizer ' 

 e.xperiments with sulphate of ammonia and nitrate of soda as a top-dressing for 

 winter wheat for the years 1898 to 1900, inclusive. In general the results were 

 favorable to the nitrate of soda, but in 1900 the results were about the same for the 

 two fertilizers. 



"Winter cereals and fertilizers applied as a top-dressing, (iuaxd {Jour. Agr. 

 Prat., 1901, I, Xv. 11, pp. S3S,3S9). — An article discussing under what conditions 

 top-dressings can be profitably applied in growing winter cereals. 



Breeding of wheats rich in gluten, E. Schrib.m'x {Jour. Aijr. Prat., 1001, I, 

 Xo. 9, pp. 274-277; Seiiiahie Ayr., 21 {1901 ), Xo. 1033, pp. 68, 69).— A discussion of this 

 subject, in which the author states that the nitrogen content of wheat is very varia- 

 ble, and that it depends much more uj)on the conditions under which the plants 

 develop than upon the variety. He points out that all circumstances tending to 

 shorten the period of growth favor the formation of nitrogenous substances in the 

 grain, and that the differences of structure in the plant and of I'ichness in gluten 

 l)etween grains of the same variety are not hereditary. Grain from hard and highly 

 glutinous seed may be the same in comi^osition as grain grown from soft, starchy 

 seed. A further conclusion is that the industrial value of productive varieties of wheat 

 is not well enough known to originate varieties which satisfy both the produ(;er and 

 the cfjnsumer. 



HORTICULTURE. 



Book of gardening; a handbook of horticulture, W. D. Drury et al. {Xeiv 

 York-: Ctiarlea Scrlli)ier Sons; London: L. Iprolt fllll, 1900, pp. 1198, )ih. 15, figs. 

 720). — This work aims to cover the whole field of horticulture, including landscape 

 gardening and the growing of fruits, vegetables, and all the more usual outdoor and 

 indoor flowers and i)lants. The 27 chapters on the various phases of these subjects 

 have been prej)ared by 13 different authors. Within the chapters on the various 

 groups of plants, like ferns, bedding plants, rock plants, orchids, stove plants, green- 

 house i)lants, cacti, a(juatics, florists' flowers, trees and shrubs, etc., the matter is 

 arranged alphabetically; the various plants are described, and concise directions given 

 for their culture. A chapter is devoted to each of such subjects as forcing, landscape 

 gardt'uing, roses, chry.santhenunns, pests generally, and manures. The book is well 

 indexed and illustrated and will he found valuable as a condensed reference work on 

 horticultural subjects.
