iiiulclied jtlats and the cultivated plats. The work is' to be continued for sev- 

 eral years. 



The results of sjiraying experiments are noted on p. 353 of this issue. 



Mangoes for export, H. H. Cousins (BuI. Dept. Agr. Jamaica, n. ser., 1 

 {1909), ISO. 1, pp. J/S-51, pis. 4), — The author points out the importance of the 

 mango industry for Jamaica, and gives brief notes on the varieties, culture, and 

 propagation of mangoes. 



Peach growing- in Arkansas, E. Walker {Arkansas Sta. Bui. 79, 2. ed. rev., 

 pp. 281-285, figs. 7). — The present edition of this bulletin (E, S. R., 15, p. 871) 

 is somewhat revised in portions to conform with more recent experience and 

 observations on peach growing in Arkansas. 



Influence of cultural operations on the growth and yield of grapes, L. 

 Ravaz {Ann. Ecole Nat. Agr. MontpclUer, n. srr., 8 {1909), No. J,, pp. 231-291, 

 figs. 19). — The results are given of a number of studies made by the author 

 relative to the influence of various cultural operations on grapes at the time 

 of bud swelling, shoot development, flowering, and maturing, as well as on the 

 yield and quality of the products. Among the influences studied were the 

 effect of the color of the soil on the grapes and on soil and air temperatures, 

 some data on which were reported last year (E. S. R., 20, p. 751), the effect 

 of different planting distances, spring frosts, mulching, time and length of 

 pruning, the number of branches, thinning the vines, the direction of the 

 branches and removal of the suckers. The results are presented in tabular 

 form and fully discussed. 



The fertilizer requirements of grapes in the Lower Loire, A. and P. An- 

 DouARD {Bid. Sta. Agron. Loirc-Inf., 1907-8, pp. 26-50). — For several years 

 past the authors have studied the composition of the leaves, shoots, marc and 

 must of a large number of grapes of several varieties with a view of deter- 

 mining the amount of each nutritive element i-emoved from the soil every year. 

 The results of these studies for the 3 years, 1905 to 1907 inclusive, are presented 

 in tabular form. 



It was found that the 5 varieties which received special attention presented 

 practically the same food requirements. From the data secured' in their work, 

 the authors estimate that an acre of grapes requires per year at least 12 kg. 

 of nitrogen, 6 kg. of phosphoric acid, 20 kg. of potash, and 24 kg. of lime. 

 The studies are to be continued. 



The grape districts of New York and table of varieties, M. if. Dorsey {Nrir

 summary of the information contained in The Grapes of New York (E. S. R., 

 20, p. 940). It discusses the natural factors influencing grape culture, gives 

 an account of the location, soil, climate, history and present status of the four 

 great grape districts of New York, and briefly describes the more important 

 species of Yitis, relative to their natural habitat, botanical differences and horti- 

 cultural importance by way of showing their significance in varieties. A table 

 is also given of 161 of the most important varieties including the species, fruit 

 and vine characters, date and place of origin or introduction, and brief state- 

 ments of their value for the grower. 



Coffee, A. Laliere {La Cafe. Paris, 1909. pp. XYI+J,17+17, pi. 1, figs. 97, 

 maps 2). — This is a treatise on coffee with special reference to its culture and 

 preparation in the State of Sao Paulo, Brazil. 



In the introduction consideration is given to coffee culture in general. The 

 succeeding portions of the work discuss the details of coffee culture in Sao 

 Paulo, its commercial preparation, the economic factors in the production of 

 coffee, the commei'ce, and the valorization of coffee. The appendix contains 

 various statistics on coffee relative to imports and exports, shipments, stocks,
