but little papain can be obtained by bleeding tlie stems and leaf stalks of 

 papayas. 



The data secured deal entirely with the papain obtained from the fruit. 

 Twenty bearing trees yielded 180 oz. of juice from which was obtained ap- 

 proximately 35 oz. of dried papain. It is concluded that under normal cir- 

 cumstances the growing of papayas for the production of papain would be 

 lucrative. 



Strawberry growing in Arkansas, W. H. Wicks (A7'kansas 8ta. Bui. 122 

 (1915), pp. 5-48, figs. 22). — A practical treatise on strawberry culture with 

 special reference to Arkansas conditions, the subject matter being based upon 

 a survey of cultural methods in various districts of the State in 1914. 



The phases discussed include soils; location; preparation of soil; varieties; 

 fertilizers; the sex of the strawberry; propagation; setting time and care of 

 plants; system of planting and setting the plants; cultivation, mulching, and 

 picking; practical carriers; packing; marketing; renewing the plants; cost of 

 production; yields; and returns. Information is also given relative to a straw- 

 berry grading plan, loading a refrigerator car, by-laws of a fruit growers' asso- 

 ciation, and instructions to shippers. 



Strawberry varieties, O. M. Taylor (New York State Sta. Bui. ^01 (1915), 

 pp. 165-192; abridged ed., pp. 8). — This bulletin comprises a report of varieties 

 of strawberries tested at the station during the past few years. The kinds 

 grown include newer varieties, with standard commercial kinds for purposes 

 of comparison. In addition to a general descriptive list of all varieties show- 

 ing essentially distinguishing characters, the varieties are listed with reference 

 to blooming season, season of ripening, sex of flowers, plant makers, productive- 

 ness, vigor of the plant, resistance to disease, size of the fruit, cjunlity, and 

 desirable kinds. 



Strawberry supply and distribution in 1914, W. A. Sherman, H. F. 

 Walker, and O. W. Schleussner (U. 8. Dept. Agr. Bui. 237 (1915), pp. 10, pi. 

 1, fig. 1). — A statistical review of the strawberry supply and distribution in 

 the United States in 1014, based upon data secured from 466 shipping stations. 

 The information, which is presented in the form of a table, a map, and a chart, 

 shows the number of carloads shipi>ed by States and by shipping districts, and 

 also shows the districts which have overlapping shipping seasons. The data 

 are presented with a view to criticism for the purpose of perfecting methods of 

 securing information of this nature. 



Grape culture, with, special reference to commercial production under 

 irrigation in eastern Oregon, R. W. Allen (Oregon Sta. Bui. 126 (1915), pp. 

 S-31, figs. 12). — This comprises a practical treatise on commercial grape grow- 

 ing, the subject matter being based upon an investigation and study of the 

 grape industry in the Columbia River basin, and of various factors bearing 

 upon the successful development of a commercial industry. 



Introductory considerations doal with the present status of the grape industry 

 in eastern Oregon and possibilities of commercial production. Consideration 

 is then given to methods of establishing the vineyard, including descriptions of 

 the more desirable varieties: planting operations; training and pruning; tillage 

 and care of the vines; and harvesting and marketing. 



A short bibliography of literature dealing with grapes and grape culture is 

 apiiended. 



Pruning and training young vines, L. Ravaz (Prog. Agr. et Vit. (Ed. VEst- 

 Centre), 36 (1915), No. 7, pp. l->i5-154, figs. 8). — A popular discussion of meth-
