of ecology and of plant distribution, has been included. As in the previous 

 fruit books some prominence is given in footnotes to biographical sketches of 

 persons connected with the development of the peach industry. The work 

 concludes with a bibliography and references. 



Pruning' experiments with peaches: Besults of first two seasons, M. A. 

 Blake and C. H. Connoks {New Jersey Stas. Circ. 83 {1917), pp. 8). — This cir- 

 cular is a summary of a bulletin to be presented at a later date. It sum- 

 marizes the results for two seasons of extensive pruning experiments started 

 in the spring of 1912. An outline is given of the experiments, and records are 

 given showing the average growth and circimaference made by three different 

 varieties subjected to various forms of pruning both at Vineland and New 

 Brunswick. The data given are intended to serve as a record and no con- 

 clusions are thus far drawn. 



Packing peaches in Georgia carriers, L. G. Giixam {New Jersey Stas. Circ. 

 82 {1917), pp. 8, figs. 4). — The directions herein given have been revised from 

 Bulletin 284 of the station (E. S. R., 34, p. 639). 



The blueberry in New Hampshire, J. H. Goueley {New Hampshire Sta. 

 Circ. 18 {1917), pp. 3-12, figs. 4)- — This circular comprises a preliminary report 

 on the blueberry industry in New Hampshire. Data are given showing blue- 

 berry shipments from different parts of the State in 1916 and yields of in- 

 dividual blueberry pastures, together with information relative to methods of 

 harvesting the crop and burning over the pastures. A partial bibliography 

 of the literature dealing with the propagation, culture, and handling of blue- 

 berries is appended. 



The banana as an emergency food crop, J. E. Higgins {Havyaii Sta. East. 

 Bui. 6 {1917), pp. 16, figs. 3). — In addition to a discussion of cultural methods, 

 the banana and banana by-products are considered with reference to their 

 nutritive value as compared with other foods. 



Comparative results of moderate and severe pruning, H. S. Reed {Col. 

 Citrogr., 3 {1917), No. 2, pp. 25, 38, figs. 8). — A progress report on some work 

 started by the California Citrus Substation in 1915 in an old navel orange 

 grove. 



As measured by the yields for two seasons after pruning, both moderate 

 and severe pruning have decreased the yield. The decrease was greater on 

 the severely pruned trees. Thus far the differences in growth resulting from 

 pruning are not pronounced. The experiment is to be continued for some time. 



The principles and practices of cooperation applied to citrus production 

 and distribution, G. H. Powell {Proc. 2. Pan Amer. Sci. Cong., 1915-16, vol. 3, 

 pp. 665-671). — In this paper, read before the Second Pan American Scientific

 the author gives an account of the various agencies cooperating in California 

 in the production, distribution, and sale of citrus fruits.

 {1917), pp. 29, pis. 7, figs. 2). — A treatise on the culture, harvesting, and mar- 

 keting of citrus fruits, including a brief review of cultural demonstrations 

 conducted at Surinam for a number of years. 



Hints on coffee growing in British East Africa, M. D. le Poeb Teench 

 {Dept. Agr. Brit. East Africa Bui. 2 {1917), pp. 1-19, figs. 5).— A popular ac-

 5). — An account of the litchi based on cultural experiments conducted at the 

 station and upon data gathered from growers in Hawaii and elsewhere. The
