whole appear to largely support those previously noted. While the use of 

 manure is advantageous to a number of crops, a large portion of the manure 

 can be economically replaced by cheaper commercial fertilizers. 



The farmer's vegetable garden, W. H. Wicks {Idaho Sta. Bui. 69, pp. 49, 

 figs. 10, dgtns. 2). — The record for 2 years is given of a i-acre vegetable garden 

 established in the spring of 1908 on the horticultural grounds of the Idaho 

 Station for the purpose of securing definite data on methods of culture, yield, 

 cost of production, and the advisability of maintaining such a garden on the 

 farms in Idaho. 



The value of the products from the i-acre in 190S was $82.19 with net 

 profits of $57.41 ; the corresponding value in 1909 was $98.38 with net profits 

 of $79.22. The conclusion is reached that by judicious arrangement of the 

 garden a continuous supply of vegetables may be secured throughout the 

 season. A plan is given of a farmer's vegetable garden, together with cul- 

 tural suggestions on farm garden crops and recommended varieties. 



Export of cucumbers {Agr. Jour. Union So. Africa, 1 {1911), No. 1, p. 7). — 

 According to this item experimental shipments of cucumbers from Natal to 

 England proved a complete failure and the exportation of this crop from South 

 Africa to England is considered impracticable. 



Selected strains of nursery stock {New England Homestead, 62 {1911), 

 No. 12, pp. Jfll, Jil2). — The opinions of several leading horticulturists are given 

 relative to the value of selected scions for the propagation of nursery stock 

 with special reference to the breeding of so-called pedigreed fruit trees. 



Contribution to the physiology of the g-raft. — Influence of the stock on 

 the scion, G. IlivifjRE and G. Bailhache {Jour. Soc. Nat. Hort. France, 4- ser., 

 12 {1911), Feb., pp. 95, 96). — In continuation of previous investigations (E. S. 

 R., 20, p. 1131) the results are given of exi^eriments with pears of a number 

 of varieties grafted on the quince and on seedling stock. Analysis of the must 

 of fruits from these various grafts showed that its density is slightly higher 

 for all the varieties of fruits harvested from the scions grafted on quince than 

 from those grafted on seedlings. The total sugar content and the proportion 

 of saccharose and of acidity are likewise more elevated. The results as a 

 whole indicate that the stock either increases or lessens the faculties of the 

 scion. 



Cleft grafting, C. O. Gouts {Newcomerstown, Ohio, 1910, pp. 48, pis. 8). — ^A 

 popular treatise on cleft grafting. 



Cold storage, precooling, and shipping deciduous fruit, A. V. Stxjbenrauch 

 {Proc. Oreg. State Hort. Soc, 25 {1910), pp. 31-58).— The author discusses 

 the various factors having important influences on the keeping quality of 

 fruit products, as determined in the fruit storage investigations conducted 

 by the Bureau of Plant Industry of this Department (E. S. R., 20, p. 840) 

 during the past 8 years. 



The following factors are considered: The place of production, method of 

 culture, seasonal influence, proper stage of maturity for storing, influence of 

 handling on keeping quality, and influence of prompt cooling. 



Tlie precooling of fruit, A. V. Stubeneauch {Cal. Fruit Grower, 43 {1911), 

 Nos. 1181, pp. ll-l'i; 1182, pp. 4, 5). — A popular discussion of the principles 

 and practice of precooling fruit as evolved in the fruit storage and marketing 

 investigations of the Bureau of Plant Industry (E. S. R., 20, p. 840). 



The fruits of Germany {Deutschland's Obstsorten, 1-6 {1905-1910), Nos. 

 1-18, pis. Ilf4, figs. 5'i, with descriptive text). — This serial publication, which is 

 edited by Muller of Diemitz, Gran of Kdrbelitz, and Bissmaun of Gotha in 

 cooperation with a great number of German pomologists, comprises descriptive
