ducted in several county districts. The results as a whole confirm those 

 previously noted (E. S. R., 23, p. 343). 



The oil palm, P. Hubert {Le Palmier a Eulle. Paris, 1911, pp. IX+31Jf, figs. 



100). ^A treatise on the oil palm (Elwis guineensis) with particular reference 



to the French Colonies. 



Part 1 contains general considerations relative to the palm-oil industry and 

 discusses the botany, varieties, and geographical distribution of the oil palm, 

 together with its habitat, climatic and soil requirements, details of the culture 

 and management of oil-palm plantations, harvesting, returns, diseases and 

 other enemies, and various uses in producing countries. Part 2 treats in detail 

 of the technology of the palm-oil industry both in producing and importing 

 countries, including the properties and uses of palm oil. Part 3 discusses the 

 commercial and economic phases of the industry. Part 4 consists of a memo- 

 randum of information relative to the French Colonies with special reference 

 to the oil palm and its industries. 



Papers on the oil palm, A. Chevalier (V^g. Utiles Afriqiie Trop. Franc., 

 1910, No. 7, pt. 1, pp. 121). — These papers as a whole consist of the results of 

 the author's investigations of the oil palm {Elceis guineensis) in French West 

 Africa. 



Chapter 1 contains general considerations relative to the extent and im- 

 portance of the palm-oil industry, and the succeeding chapters deal with the 

 oil palm relative to its history, geographical distribution, botany, varieties, 

 biology, and culture, the harvesting of the fruits, preparation of the oil and 

 nuts, marketing and exporting, and the future of the oil palm and methods of 

 increasing its production in the French colonies. The principal publications 

 dealing with the oil palm are listed. 



Isothermic installations for the transport of fruits, Danis (i. Cong. Inter- 

 nat. Froid [Paris], Rap. et Commun. 1908, III, pp. 691-115). — A paper read 

 before the First International Congress of Refrigeration, Paris, 1908, in which 

 the author discusses the various methods and equipment involved in the cold 

 storage transportation of fruits. 



Refrigeration of citrus fruits in transit from California, J. S. Leeds {1. 

 Cong. Internat. Froid [Paris], Rap. et Commun. 1908, III, pp. 602-612). — A paper 

 on this subject presented to the First International Congress of Refrigeration, 

 Paris, 1908, in which the author deals largely with the methods of opera- 

 tion employed by the refrigerator car line service in handling the citrus fruit 

 crop of California. 



Sea transport of bananas by refrigeration, H. J. Ward (1. Cong. Internat. 

 Froid [Paris], Rap. et Commun. 1908, III, pp. 115-780, figs. 2).— In this paper 

 which was presented before the First International Congress of Refrigeration, 

 Paris, 1908, the refrigerating and ventilating systems used in the English 

 banana trade are described. 



Tests made on flowering plants in the cold storage plant at Amsterdam, 

 P. DE Vries {1. Cong. Internat. Froid [Paris], Rap, ct Commun. 1908, III, pp. 

 10-13). — A paper presented to the First International Congress of Refrigeration, 

 Paris, 1908, in which the general results are given of a comparative trial of 

 various flowering shrubs and bulbs to determine the effect of artificial cold 

 storage upon their subsequent growth and flowering. 



For the most of the plants stored no particular influence, either favorable or 

 unfavorable, was produced by the cold. Lilacs and lilies of the valley, how- 

 ever, were considerably improved by cold storage, both as to the development 

 of the flowers and in hastening the blossoming period. The cold-storage process 

 appears to be especially applicable in countries such as Holland where the 

 winter dormant period often does not set in until the end of December.
