Second note on the wild coffees of Mount Amber, Madagascar, M. Dtjbard 



(Agr. Prat. Pays Chauds. 6 {1906), .¥o. //5, pp. 518-521. figs. 2).— In the first 

 notes on this subject (E. S. R., 16, p. 976) the author descril)es 3 wild varieties 

 of coffee found on Mount Amber, Madagascar, viz, Coffea gallienii, C. bonnieri, 

 and C. mogeneti. In the present note he adds further remarlcs on these 3 

 varieties and describes a new variety which he has received from Madagascar 

 called C. augagncuri. This variety is said to be well characterized in the form 

 of its leaf and the peculiarity of its fruit. 



The cocoanut, P. Hubert (Le Cocotier. Paris: H. Dunod and E. Piuat, 

 1906, pp. XIV +135, figs. 39). — Cocoanut cultivation, insect enemies, and related 

 questions are discussed, as well as the manufacture and use of copra, des- 

 iccated cocoanut. cocoanut oil. and other cocoanut products. 



The practical culture of cacao trees, A. Fauchere {Paris: A. Challamel, 

 1906, pp. 115, figs. 40). — This is a treatise on the culture and preparation of 

 cacao for the market, with special reference to the development of the indus- 

 try in Madagascar. The work is based on methods in vogue in Central Amer- 

 ica, the Antilles, Ecuador, Venezuela, Trinidad, the Guianas, Brazil, and 

 Mexico, and deals with the natural distribution, history, species and varieties 

 in use, climatic and soil adaptabilities, animal and insect enemies, and the im- 

 portant phases of culture and management. 



Estimates are given of the cost of planting, cultivating, and maintaining 

 cacao plantations both under personal supervision and by contract for a period 

 of 10 years. The processes of fermentation, drying, and preparing the cacao 

 fruit for the market, together with the apparatus pertaining to these processes, 

 are discussed in full. Two appendixes are included in the work, which deal 

 with the importance of cacao culture and special suggestions for the man- 

 agement of the plantation with reference to Madagascar. The work is illus- 

 trated by numerous figures. 



The yucca, R. J. Fosalba {Bol. Agr. [8an ^Salvador], 6 {1906); A'o, 12, pp. 

 579-596). — This is a reproduction of the author's report to the minister of for- 

 eign relations of Uruguay on the relative importance and uses of the yucca in 

 the West Indies, Mexico, South America, Florida, and Java. It consists of a 

 collection of notes on the uses and present status of the yucca industry in the 

 different countries mentioned, together with a description of the cultivation of 

 this plant in Cuba. 



Some of the important products of the yucca are starch, alcohol, tapioca, and 

 yucca fiour. The starch is considered in Cuba to be of superior quality to 

 all imported starches. As a flour, yucca is inferior to wheat, but is of great 

 importance to natives of the poorer classes in the West Indies when they are 

 unable to purchase other foods. A bibliography is given, including the various 

 sources from which the author derived infoi-mation. 



The influence of cold in horticulture, A. II. Ferret {Rev. Sci. [Paris], 

 S. ser.. 7 {1907), Xo. 6, pp. 170-17 Jf). — The author discusses the utilization of cold 

 storage in retarding the blooming period and the preservation of blooms of com- 

 mercial flowering plants, bulbs, and shrubs. A brief account of the harvesting, 

 grading, storing, and forcing of lilies of the valley and flowering bulbs near 

 Hamburg. Germany, is given, together with recent experiments of M. J. ;Mer- 

 cier, of Dijon, on the influence of cold storage in the preservation of cut 

 flowers. 



In these experiments two cold-storage mediums were used, an ice house and an 

 artificial cold-storage room. The ice house had a temperature of about 2° C. 

 with a relative atmospheric humidity of 90 parts per 100, while the temperature 

 of the cold-storage room was about 5° C. with a relative humidity of 60 parts
