results are reported to have been obtained by tlie use of a ridging implement 

 with oats and barley as compared with harrowing or hand cultivating. 



Spraying with a 25 per cent solution of iron sulphate when wild mustard

On the castration of plants, E. Heckel (Rev. Sci. [Paris], 51 {1913), I, No. 

 8, pp. 225-228). — The author reports increases in the sugar content of sorghum 

 and maize plants, in some cases as much as 13o per cent, after complete or par- 

 tial castration by removing both male and female organs or only the female

Under what conditions is the theory of probabilities applicable in agri- 

 cultural experiments? B. Baule iFiihling's Lanclw. Ztg., 62 {1913), No. 5, 

 pp. 160-180, figs. 8). — This is a mathematical discussion based upon Gauss'

HORTICULTURE. 



A market g'arden and truck survey of the Ohio and Kanawha River 

 Valleys in West Virginia, A. L. Dacy {West Virginia Sta. Bui. IJfS {1914), 

 pp. SJf, figs. 13). — The author here presents the results of a survey by himself 

 and R- R. Jeffries of the vegetable growing industry in the Ohio and Kanawha 

 river valleys, including also several miles of bottom lands on a number of 

 creeks. The survey was conducted as a basis for the further study of the 

 problems affecting the market gardening and trucking industry in the State. 

 The data discussed deal Vv'ith the extent of the industry, cultural practices, and 

 methods of marketing. 



The survey showed that vegetable growing is already of considerable magni- 

 tude in the Ohio and Kanawha River Valleys and that the average returns are 

 much greater than those from the ordinary farm crops. While it is believed 

 that better cultural methods would yield an increased amount of vegetables, 

 the chief hindrance to the development of the industry appears to be a scarcity 

 of labor to farm the land. 



The home vegetable garden, T. C. Johnson and F. E. Miller {Virginia 

 Truck Sta. Bui. 10 {191Jf), pp. 207-266, figs. 9).— A practical treatise on vege- 

 table growing with special reference to the home garden. Introductory con- 

 siderations deal with the general principles of vegetable growing. Cultural 

 details are then given for growing various kinds of vegetables, including musk- 

 melons and watermelons, adapted for growing in Vii-ginia. 



Tomato investigations, J. G. Boyle {Indiana Sta. Bui. 165 {1913), popular 

 ed., pp. 3-8. figs. 3). — A popular summary of the bulletin previously noted (E. S. 

 K., 29, p. 434). 



Report on foreign markets for Oregon fruit and laws governing importa- 

 tions, S. F. Lamb {Ann. Rpt. Oreg. State Hort. Sac., 4 {1912), Sup. [pub. 1914], 

 pp. 89). — A compilation of data and information secured from consular reix)rts, 

 showing the status of various foreign markets with reference to the utilization 

 of fresh, dried, and canned fruits. Statistics of fruit imports of foreign 

 countries, together with laws and regulations of foreign countries concerning 

 American fruits, are also given. 



Truit culture and cold storage, P. Berg^is {An. Soc. Rural Argentina, 4S 

 {1914), No. 1, pp. 36-53, figs. 11). — This comprises a statistical study of the 

 production, consumption, and commerce of fruits in Argentina, together with 

 suggestions relative to means of extending the fruit industry in which special 

 attention is given to the employment of precooliug and refrigeration in the 

 storage and transit of fruits.
