Culture of the Logan blackberry and related varieties. O. M. Darrow (U. S. 

 Dept. Agr., Fanners' Bui. 998 (1918), pp. 24, figs. 11).— This publication deals 

 with the culture of the Logan blackberry, also popularly known as the logan- 

 berry, in the milder parts of California, Oregon, and Washington. Informa- 

 tion is given relative to the status of the industry, origin of the variety, extent 

 of culture, location, and site of the plantation, planting, training, and priming

 propagation, and related forms and hybrids. 



Cranberry investigations, T. J. IlEAm.EE (Proc. Amrr. Cranberry Growers' 

 Assoc, '/!> (1918), pp. 11-19). — The cooperative cranberry experiments that are 

 being conducted under the direction of the New Jersey Experiment Stations 

 (E. S. R., 37. p. T4."> i were replanned during the year and limited for the 

 present to problems of plant food, soil acidity, soil water, and insects. The 

 present report reviews the results of previous fertilizer exi>eriments, briefly 

 notes some initial soil acidity experiments, and outlines future fertilizer and 

 soil acidity experiments. 



Temperatures of small fruits when picked, N. E. Stevens and R. B. WlLOOZ 

 {Plant World, 21 (1918), Jfo. 7. pp. 176-183). — Observations on a variety of 

 small fruits here reported show that on clear days they usually have a 

 temperature considerably above that of the air. No constant difference in tem- 

 peratures of fruits of the same variety, but of different colors, was observed. 

 The rise in temperature appears to be mostly due to the absorption of radient 

 energy from the sun: it was not noticeable at night nor on cloudy days, and 

 berries in the shade are uniformly cooler than those in the sun. A list of cited 

 literature is appended. 



Home storage houses for fruit, E. N. Fagan (Pmn. 8tate Col. Ext, Circ. 74 

 (1918). pp. 18, figs. 85). — This circular gives suggestions for constructing home 

 storage houses. Including illustrations of various methods of construction. 



Home vegetable and fruit storage (Mass. Agr. Col. Ext. 8erv. Bui. 26 

 (1918), pp. 7, figs- 2). — Suggestions are given for storing various classes of 

 fruits and vegetables, including directions for constructing a cool storeroom in 

 the cellar. 



Report of nut tree investigations in Maryland. E. S. Johnston (Maryland 

 Sta. Bui. 218 (1918), pp. 239-2(1'). figs. 2).— With the view of determining the 

 range of country wherein different varieties of Tersian walnuts and pecans 

 can be grown, the station distributed a number of these trees in various sections 

 of the State during the three years, 1007-1000. This bulletin contains a report 

 of the present status of these trees and of trees growing at the station, together 

 with notes on the records of other nut trees In different counties of Maryland and 

 n list of varieties of walnuts and pecans recommended for planting. Informa- 

 tion is also given relative to the economic importance of nuts. A brief bibU 

 raphy of nut publications is included. 



In all. 1,500 walnut and pecan trees were distributed. It is found that a 

 greater percentage of trees have survived in the counties on the Eastern Shore 

 and in the counties of Anne Arundel, Calvert. Washington, and Montgomery. Of
