344 EXPERIMENT STATION EECORD. 



The work at the branch stations and farms consisted largely of variety tests. 

 Analyses of lime-sulphur washes and arsenate of lead are also reported. 



Beginners' guide to fruit growing, F. A. Waugh {ISlew York, and London, 

 1912, pp. 120, pi. 1, figs. 62). — This work is offered as a simple statement of 

 the elementary practices of propagation, planting, culture, fertilization, prun- 

 ing, spraying, etc. It also includes chapters on varieties of fruit for different 

 sections and orchard renovation. 



Horticultural statutes of the State of California, 1912 (Sacramento: Btatc 

 Com. Hort., 1912, pp. 1-^6). — This comprises the horticultural statutes with 

 court decisions and legal opinions relating thereto, also state quarantine and 

 county ordinances relating to horticulture, and a list of state and county horti- 

 cultural officers corrected to February 1, 1912. 



Combating orchard and garden enemies, "W. H. Chandler (Mlssovri Sta. 

 Bui. 102, pp. 239-290, figs. 37). — The more important insect pests and fungus 

 diseases of fruits and vegetables are briefly described, and directions are given 

 for their control as well as for the preparation of fungicides and insecticides 

 and for protecting trees against rabbits and mice. 



Ampelography of the Crimea, S. Kobshinsky (Trudy Biuro Prikl. Bot. 

 (Bui. Angew. Bot.), 3 (1910), No. 9-10, pp. 323-^78; 4 (1911), Nos. 8-9, pp. 

 267-458; 10, pp. J,65-5i,0, pis. 6-',, figs. 102).— A descriptive account of the culti- 

 vated varieties of grapes in the Crimea, based on studies conducted in the 

 period 1898 to 1900. A number of self- and cross-pollination experiments con- 

 ducted with 23 Crimean grape varieties are also described. 



The text is accompanied by a number of illustrations showing the character 

 of the fruit and foliage of different species. 



Statistics on the production of grapes and olives in 1911 (Estadistica de 

 las Prndnccioncs Viiicola y Olivarera en el Ana 1911. Madrid: Govt., 1912, pp. 

 9). — ^A statistical review of the production of grapes, wine, olives, and olive 

 oil in the regions and Provinces of Spain for the year 1911. 



Citrus experiments, A. W. Blaib (Florida Sta. Rpt. 1911, pp. XXVII-XXXI, 

 figs. 3). — This comprises a progress report on the fertilizer experiments with 

 citrus fruits previously noted (E. S. R., 25, p. 427). Measurements have been 

 made of the trees on each plat 3 times a year and tabular data are given 

 showing the average gain in diameter of the trees on each plat from June 7, 

 1909, to June 21, 1911. 



The experiment thus far does not indicate any marked growth increase in 

 favor of any particular fertilizer used. The clean culture plats on the whole 

 are slightly above the general average in appearance, and some of the trees in 

 the plat which has received no fertilizer are beginning to indicate by a yellow- 

 ing of the leaves a need of nitrogen. Considerable die-back was observed in 

 the grove in 1910, but no relationship was found between the fertilizers used 

 and the presence or absence of die-back. 



A practical method of artificially ripening Japanese persimmons, F. E. 

 Lloyd (Proa. Ala. State Hort. Soc, 9 (1912), pp. 57-63).— The author reviews 

 Gore's experiments in ripening persimmons with carbon dioxid (E. S. R., 25, 

 p. 744), and summarizes the results secured in his own work at the Alabama 

 College Station during 1911 (E. S. R., 26, p. 327). 



Large scale experiments on the processing of Japanese persimmons; with 

 notes on the preparation of dried persimmons, H. C. Gore ( U. S. Dept. Agr., 

 Bur. Cliem. Bid. 155, p-p. 20, figs. 3).— In previous experiments conducted co- 

 operatively by the Bureaus of Chemistry and Plant Industry (E. S. R., 25, 

 p. 744) it was found that upon keeping unrii>e i>ersimmons for several days in 

 an inert gas, such as carbon dioxid, they become nonastringent while remain- 

 ing firm. During the season 1911 these experiments with carbon dioxid were
