London, and the India Rubber World, of New York. 

 Although primarily concerned with the supply, manu- 

 facture and consumption of rubber, these periodicals do 

 not neglect the industry from the grower's point of view, 

 and in connection with plantation manufacture these 

 journals are particularly worth perusal by the tropical 

 planter. A third journal of value to the rubber grower 

 is Tropical Life of London. 



From the purely agricultural aspect, the most important 

 papers on rubber growing make their appearance in the 

 publications of the Department of Agriculture, Federated 

 Malay States, and in those of the Department of Agricul- 

 ture, Ceylon, including the Annals and Circulars of the 

 Royal Botanic Gardens, Peradeniya. Useful information 

 appears occasionally in the Bulletins of the British Guiana 

 and Trinidad Departments of Agriculture, as well as in 

 the West Indian Bulletin of the Imperial Department of 

 Agriculture for the West Indies. 



The state of the French rubber trade finds an outlet 

 in the Bulletin de V Association, des Planteurs dc 

 Caoutchouc, whilst important information on rubber 

 planting appears from time to time in the Journal 

 d' Agriculture Tropicale, in L' Agriculture Pratique des 

 Pays Chauds, and in that interesting and particularly well- 

 illustrated periodical, the Bulletin Agricole du Congo 

 Beige. Valuable papers concerning rubber in the German 

 colonies are to be found in Der Tropenpflanzcr, whilst 

 accounts of South American work appear from time to 

 time in the various Bulletins of the Latin-American 

 Republics. 



As regards official publications that devote attention 

 to rubber which are issued from London, reference must 

 be made to the Bulletin of the Imperial Institute, which 

 is yearly becoming more indispensable and almost inter- 

 national in importance. As a source of reference on the 

 technology and chemistry and economics of rubber this 

 journal is of special value. For botanical information 

 the Kew Bulletin frequently proves a fertile source of 

 reference, whilst for trade notices and changes of legis- 

 lation and production statistics the Board of Trade 

 Journal should be consulted.
