more scientific articles appear occasionally in the Depart- 

 ment's Bulletin. The Hawaii Experiment Station has of 

 late been issuing considerable literature on bananas, as 

 has also the Queensland Department. It may be well to 

 record here the fact that a useful literary service has 

 recently been rendered through the publication of two 

 books one, entitled "Coco-nuts: The Consols of the 

 East," and a second, "The Banana: Its Cultivation, 

 Distribution, and Commercial Uses." These works 

 bring* together in compact form a large amount of infor- 

 mation which was previously very diffused. 



Cacao and Citrus Fruits. 



The chief cacao growing countries are Ceylon, 

 Trinidad, Grenada, the Central American Republics, Gold 

 Coast, and the Cameroons. It is thus natural to find 

 that most of the literature in circulation dealing with the 

 cultivation of this crop emanates from the Departments 

 and Societies in these places. As with most of the other 

 industries, the growing of cacao is not neglected by 

 the Philippine agricultural authorities. Much of the 

 work published in Trinidad, Grenada, and Dominica in 

 connection with cacao has referred to sanitation and the 

 question of manuring; more attention is now being given 

 to vegetative propagation and selection. The German 

 publications are the best on fermentation and allied 

 matters. In this connection reference may be made to 

 the useful collection of papers on this subject in a book 

 called the " Fermentation of Cacao." This affords 

 another demonstration of the extent to which agricultural 

 information in the Tropics is scattered. It is of value 

 to note here that a useful journal for information on the 

 cacao market is the Gordian, published at Hamburg. 



Turning to publications which devote attention to citrus 

 fruits, it is found that they are principally those issued 

 by the Experiment Stations in the Southern States of 

 America, the American Genetic Association, and by the 

 Imperial Department of Agriculture for the West Indies. 

 The Perfumery and Essential Oil Record and Messrs. 

 Schimmel's Reports are often valuable for information 

 concerning citrus products. Citrus culture extends into
