240 EXPERIMENT STATION EECOED. 



been grown continuously during the past 12 years. The results appear to dis- 

 prove the theory that the hill system produces the largest average size fruit. 

 When the yearly averages are taken the narrow-inatted row appears to produce 

 the largest and most uniform grade of fruit, while the hill system yields the 

 smallest berries. 



Grape growing, O. B. Whipple (Colorado 8ta. Bui. l.'fl, pp. 3-16, figs. 8). — 

 This bulletin contains detailed suggestions for grape gi'owing under irrigated 

 conditions in Colorado, in which the following phases are considered : Soils 

 and locations, propagation, preparation of land, planting, cultivation, irrigation, 

 pruning, summer ]iruning, winter protection, fertilization, picking, packing, 

 varieties, insects and diseases. Estimates are also given on the cost of growing 

 and returns. 



Studies conducted in the experimental vineyards of Messina on the resist- 

 ance, breeding", and culture of American grapes during the biennial period 

 1907-8, La Faugi (Boh Mm. Agr., Indus, c Com. [Rome], S (1909), 8cr. C, 

 No. 10, pp. 10-18). — This is a report on studies conducted with a large number 

 of European and American grapes and their hybrids, including grafted and 

 direct bearing vines, relative to their resistance to phylloxera, their production, 

 culture and condition. The important data are classified in tabular form. 



Adaptability of the white and red Delaware grapes, G. de Istvanffi (Bui. 

 Inst. Cent. Amp6lol. Roy. Hongrois, 1 (1906), pp. 60-62). — As a result of tests 

 conducted for 6 years in the Hungarian state nurseries, both the white and red 

 Delaware grapes were found to be unsatisfactory as regards their resistance to 

 phylloxera, their yield, and the production of high grade wine. 



Practical advice to grape growers, M. D. Chauliac (Bui. Off. Gotrvt. G6n. 

 Algcric, 1909, No. 10, Hu/)., pp. 73-706). — Practical directions, including methods 

 of culture, propagation and varieties for reconstituting phylloxera-infested 

 Algerian vineyards with American grai)e stocks, are given. The appendix 

 contains data relative to the cost of replanting vineyards. 



[Note on injury to nursery stock by fumigating with hydrocyanic-acid 

 g'as], C. W. Waid (Ohio Hfa. Circ. 89. pp. 7, 8). — The author reports a sus- 

 pected case of hydrocyanic-acid gas poisoning of j^oung apple trees secured from 

 a nursery in which the trees had been fumigated for San Jose scale. He is of 

 the opinion that the possible danger of injury to nursery stock not perfectly 

 dormant when thus fumigated is sufficient to warrant careful and thorough 

 investigation. 



Fertilization of the almond tree, G. A. Cowie (Trop. Life, 5 (1909), No. 5, 

 pp. 68-70, figs. 3). — The author suggests fertilizer formulas for growing almonds 

 on different types of soil, and gives the i-esults of a manuring experiment with 

 almonds conducted with E. Albiach, Alicante, Spain, in which a complete fer- 

 tilizer consisting of 330 lbs. of superphosphate, SO lbs. of niti'ate of soda, SO lbs. 

 of sulphate of ammonia, and 450 lbs. of kainit gave a yield per acre of 1,532 

 lbs. of almonds, as compared with 433 lbs. per acre on unmanured land. This 

 increase in yield was secured at an added cost per acre for fertilizer of 

 about $30. 



A revised list of the plats on the experiment station, Peradeniya, R. H. 

 Lock (Circs, and Agr. Jour. Roy. Bot. Gard. Ceylon, 4 (1909), No. 15, pp. 125- 

 llfO, map 1). — This is a guide to the plats of the Peradeniya experiment station, 

 the majority of which are planted to cacao, rubber, coconuts, and tea. The 

 data for each plat consist of a brief record relative to its past history, and its 

 condition at the end of 190S. 



The science of plant breeding', H. H. Groff (Ann. Rpt. Hort. ,Socs. Ontario, 

 3 (1908), pp. 76-85, figs. 6). — A popular discussion of plant-breeding methods 

 with frequent references to the author's work in breeding gladioli.
