quantity of fruit produced. The observations seem to indicate that an appli- 

 cation of a fungicide during full bloom would be advantageous, especially on 

 scab susceptible varieties. 



Some effects of high temperatures and humidity upon the keeping quality 

 of Bartlett pears, R. H. Taylor and E. L. Ovebholseb (Mo. Bui. Cal. Corn. 

 Hort., 8 (1919), No. 3, pp. 118-125).— The preliminary investigation here re- 

 ported confirms the results secured by Shamel as to the retarding effect of 

 high temperatures on the ripening of pears when stored under high humid 

 conditions (E. S. R., 36, p. 741), and indicates that both the high temperatures 

 and high humidity were responsible for the retarding effect. The authors 

 conclude that while the experiments show that temperatures ranging from 95 

 to 110° F., with the optimum at about 104 to 105°, will delay or prolong the 

 normal ripening process of Bartlett pears at least two weeks when contrasted 

 to fruit placed at average room temperatures of 70 to R0°, the danger from rot 

 and the development of abnormal flavors limit the practical use of these higher 

 temperatures. 



How the strawberry sets fruit. W. D. Valleau (Minn. Hort.. 46 (1918), 87* 

 12, pp. 449-454, figs. 4)- — A contribution of the Minnesota Experiment Station. 

 discussing the flower cluster and flowering habit of the strawberry with rela- 

 tion to the formation of nubbins, the decline in size and yield of fruit in the 

 latter part of the picking season, and the relative productivity of pistillate 

 and staminate varieties. The paper Is based on the author's study of sterility 

 in strawberries (E. S. R., 39, p. 48). 



Strawberry varieties in the United States. G. M. DaSBOW {U, B. Dept. Apr.. 

 Farmers' Bui. 10J/S (1919), pp. 36, figs. 8). — An aid to both commercial ami 

 amateur strawberry growers in the selection of varieties best suited to their 

 needs and conditions. The varieties listed, which are given for different sec- 

 tions and regions, are based upon information furnished by successful growers, 

 commercial canners. experiment station tests, and the author's personal obser- 

 vations. Varieties having particular value for different purposes are grouped 

 under appropriate heads. 



Strawberry culture. — Eastern United States. G. M. Darrow (F. S. Dept. Apr.. 

 Fanners' Bui. 1028 (1919), pp. 50, figs. 18). — This bulletin discusses commercial 

 methods in the eastern United States, Including approximately one tier of 

 States west of the Mississippi, but not including the South Atlantic and Gulf 

 coast region. In addition to complete directions for growing, harvesting, and 

 marketing strawberries, methods of using the surplus in canning, preserving, 

 and by means of cold storage for future use are also presented. 



Strawberry culture. — South Atlantic and Gulf coast regions. G. M. Darrow 

 (U. S. Dept. Agr., Farmers' Bui. 1026 (1919), pp. 40, figs. 21).— A bulletin sim- 

 ilar to the above, describing methods of growing and handling strawberries 

 adapted to the South Atlantic and Gulf States. 



Strawberry culture.— Western United States. G. M. Darrow (F. .<?. Dept. 

 Agr., Farmers' Bui. 1021 (1919), pp. 29, figs. 16).— A bulletin similar to the 

 above discussing commercial strawberry practices in the irrigated regions of 

 the West. 



Fig growing in the South Atlantic and Gulf States. D. F. QOOXD (F. s. 

 Dept. Agr., Farmers' Bui. 10S1 (1919), pp. 45, figs. 24).— This describes the 

 varieties of figs most suitable for the South Atlantic and Gulf States, their 

 culture and protection from diseases and insects, and methods of making them 

 Into desirable products for the table.
