642 EXPERIMENT STATION EECORD. 



Orchard report of Baton Rouge Station ( Loiii-siaiia Stas. Bui. 112, pp. 3-^9, 

 pg.s. l-'i). — This report summarizes the observations made ou the varieties of 

 orchard and small fruits tested in the station orchai'd at Baton Rouge since its 

 establishment in 1889-90. The report concludes with a discussion of orchard 

 pests and diseases and their control, and orchard fertilizers. It is believed 

 that the observations are sufficiently complete to prove of value to those inter- 

 ested in fruit culture upon the blnff soils of the State. 



[Reports of the fruit experiment stations], H. L. Hutt et al. {Ann. Rpt. 

 Fruit E.rpt. Htas. Ontario, U/ (191)1). pp. 19-9 'f, figs. 9, map 1). — A progress 

 report on the work of variety testing at the various fruit experiment stations 

 throughout Ontario, including sei)arate reports by the experimenters in charge of 

 each station. In the appendix are given lists of the varieties of fruits recom- 

 mended to be grown for market in the province, including lists of varieties 

 especially adapted to the sections represented by each station. 



Fruit culture, A. Gomes do Carmo (0 Brasil: Suas riquczas naturaes; suas 

 industrids. Rio de Janerio: Centra Indus. Brasil, 1908, Portugese ed., vol. 2, 

 pp. 335-37S). — An account is given of the present status of fruit culture and 

 wine making in Brazil including descriptive lists of tropical and acclimatized 

 fruits adapted to that country. 



The influence of peat mull on the root development of young' fruit trees, 

 YuNGE {Ber. K. Lehranst. Wein, Obst u. Gartenbau Geisenheim, 1907, pp. 78, 79, 

 fig. 1 ) . — Finely divided peat dust saturated with liquid manure and worked into 

 the soil in a similar manner to that used with stable manure was found to 

 produce a strong fibrous root growth with young fruit trees. As a result of 

 this trial the station recommends the use of peat mull to nurserymen. 



May weather and fruit harvests, F. H. Hall (New York State 8ta. Bui. 

 299, popular ed., pp. 2-8). — A popular etlition of Bulletin 299 of the station 

 previously noted (E. S. R. 20, p. 41). 



Investigations on the life activities of stored fruits, O. Schneider-Orelli 

 (Landw. Jahrh. Sclmeiz, 22 (1908), Xo. 10, pp. 545-563).— The author briefly 

 reviews the literature on this subject and reports on several respiration and 

 transpiration experiments conducted with fruit stored in bright and dark 

 locations, together with experiments on the respiration of injured stored fruits. 



Sunlight, through its warming effect, was found to increase both the respira- 

 tion and transpiration of stored fruit and should not be allowed to enter the 

 storage place. Diffused daylight on the other hand did not appear to materially 

 influence the life activities of stored fruit. Where there was injui'y to the fruit, 

 however, a respiration acceleration was evident for several days. 



Seedless grapes and orchard fruit, H. MiJLLER-THUKGAU (Landic. Jahrh. 

 Schweiz, 22 (1908), No. 10, pp. 564-597, figs. 7').— A study of the recent literature 

 on this subject with an account of recent observations made by the author. The 

 subject is discussed under the following general headings : The occurrence of 

 parthenocarpie with pip fruits, the importance of parthenocarpie for the orchard, 

 parthenocarpie with grapes, conditions favorable to the development of seedless 

 fruits, and the influence of the seed upon the size, shape and inner structure of 

 the fruit. A bibliography is apiiende<I. 



Fertilizer experiments with grapes, E. Zacharewicz (Rev. Vit., 30 (1908), 

 No. 770, pp. 313-318). — A further report on fertilizer experiments being con- 

 ducted with grapevines on different soils in the department of Yaucluse. Prac- 

 tically the same conclusions are reached as in the worli previously noted 

 (E. S. R., 19. p. 946). 



Viticulture in the department of Constantine, H. Perruchot (Buh Off. 

 Gouvt. Gen. Algerie, 1908, Xo. 20. Sup., pp. 239-275). — A report on viticultural 

 conditions in Constantine, Algeria, relative to the methods of combating the
