French gardening, T. Smith (London, 1909, pp. XXIX+12S, pis. 22, figs. 6, 

 dgm. 1). — In this book the principles, equipment, and cultural operations em- 

 ployed in the intensive vegetable culture known as French gardening are con- 

 sidered in great detail, including specific directions for growing various crops, 

 marketing, estimates for establishing and maintaining a French garden, a 

 monthly work calendar, garden plans, etc. 



The production of vegetable seeds: Sweet corn and garden peas and beans, 

 W. W. Tracy, Sr. {TJ. 8. Dept. Agr., Bur. Plant Indus. Bui. 184, PP- 39, figs. 3).— 

 This paper is based upon the author's personal experience in the production 

 of vegetable seeds. General consideration is given to present conditions and 

 practices in vegetable seed growing, together with the details of growing sweet 

 corn, garden peas and beans for seed in quantity and as stock seed. 



Orchard soils of the county of Cumberland, H. I. Jensen (Agr. Gas. N. 8. 

 Wales, 21 (1910), No. 6, pp. If61-J,63). — Analyses of samples of sandstone, shale, 

 and basalt soils collected in the best orange orchards of this county are reported. 



The composition of these soils, which have been heavily manured for a num- 

 ber of years, is compared with virgin soils of the same origin. This shows that 

 cultivation and manuring have completely altered both the mechanical and the 

 chemical condition of the sandstone and shale soils. " Originally very different, 

 they have, by working and fertilizing, been brought to the condition of good 

 basalt soils, and original differences in chemical and mechanical composition 

 have been almost eliminated. It is clear from this fact that the ideal virgin 

 soil for citrus fruit is a loose and friable basalt soil, such as would be produced 

 by decomposition of feldspar basalt, in which a sandy or porous texture is 

 maintained by the resistance to weathering of soda feldspar crystals." 



The influence of various fertilizers on fruit trees, H. Mxjller and O. 

 Schneider (Landw. Jahrh. Schweiz, 24 (1910), No. 4, PP- 226-23//).— Tabular 

 results for the period from 1906 to 1909, inclusive, are given relative to orchard 

 fertilizer experiments conducted at the Wadenswil station. 



The results as a whole indicate that an insuflicient quantity of nitrogen 

 diminishes the yield considerably, and may cause a slight chlorosis condition. 

 No definite results were noted as to the use of phosphoric acid. Deficiency of 

 either potash or lime tends to diminish the yield considerably. 



Better methods in eastern orcharding, F. C. Sears (Ann. Rpt. N. J. Bd. 

 Agr., 37 (1909), pp. 105-121). — A paper with the discussion following, in which 

 the writer presents the main facts of the orchard situation both East and West, 

 and offers some specific suggestions for raising the standard of the orchard 

 industry in the East. 



Native and tropical fruits, H. A. Van Hermann (Ann. Rpt. Cuban Nat, 

 Hort. Soc, 4 (1910), pp. iSS-i^S).— Popular descriptions are given of a number 

 of native and tropical fruits adapted for culture in Cuba. 



Olive culture, G. d'Utea (Bol. Agr. [8do Paulo], 11. ser., 1910, No. 5, pp. 

 345-380, figs. 8).— This is a monograph on the olive, treating of its history, geo- 

 graphic distribution and botany, details of propagation and culture, varieties, 

 harvesting, oil pressing, and diseases and other enemies of the olive. 



The olive tree, P. H. Cram (Daily Cons, and Trade Rpts. [U. 8.], n. ser., 1 

 (1910), No. 44, pp. 589-591). — A consular repdrt discussing the varieties of olive 

 trees planted, their characteristics, and the manner of planting, irrigating, 

 pruning, and fertilizing in sputheini France. 



Grape investigations in the Vinifera regions of the United States with 

 reference to resistant stocks, direct producers, and Viniferas, G. C. Husmann 

 (V. 8. Dept. Agr., Bar. Plant Indus. Bui. 172, pi). 86, pis. 8, figs. 30. map 1).— 

 This bulletin is a preliminary report upon the investigations started by the 

 Bureau of Plant Industry in 1902.
