THE INDIA RUBBER WORLD 



ANOTHER RUBBER WEED. 

 There is still another plant, a pest in times of peace, that has 

 been examined for the rubber it contains. It is the Tithyi)wlus 

 pcplus. Cultivated and treated in the same manner as the Euphor- 

 bias, it produces per hectare 43 kiloS of rubber and 120 kilos of 

 fat. Not quite as Rood as the Euphorbias, but perhaps worth 

 exploitation wlien labor is forced, fats almost unobtainable, and 

 rubber worth $12 a pound. 



THE EDITOR'S BOOK TABLE. 



FUNGI AND DISEASES IN PLANTS. BY E. I. BUTLER, M. B.. 

 F. L. S. Thacker, Spink & Co., Calcutta and Simla, India. (Cloth, 

 6'/j by 9}i inches, 206 illustrations, 5-47 pages.) 



THIS valuable handbook on the crop diseases of India caused 

 by fungi is practically if not actually the first in an impor- 

 tant and unexplored field. It was intended that the book should 

 be primarily for the use of the trained stafif of the Agricultural 

 Departments in India, but will be found useful to every planter 

 and to students of plant diseases. The book deals with field and 

 plantation crops only. It is divided into two parts, the first of 

 which comprises a general treatment including chapters on the 

 nature of fungi; the food of fungi; life-history of parasitic 

 fungi ; the causation of disease by fungi, and the principles of 

 the control of plant disease. The second part treats of special 

 diseases of many Indian crops, concluding with a chapter of the 

 diseases of rubber {Hevea, Manihot, Castilloa and Ficus). 



Ten rubber-tree diseases are minutely described in their 

 various phases, and methods of control are suggested where 

 known. The well-known "pink disease" and "black thread" are 

 stated by the author to be, at present, the most serious diseases 



of Hevea in India.

NEW TRADE PUBLICATIONS. 



THE Link Belt Co., Chicago, Illinois, has issued a hand- 

 soine 52-page booklet devoted to "Economical Handling of 

 Coal and Ashes, and Reserve Coal Storage," with many explana- 

 tory diagrams and half-tone illustrations. It is not a catalogue, 

 but a description of improved fuel-handling devices in many of 

 the best industrial power-plant installations of the country, and it 

 will be studied with interest and benefit by rubber men contem- 

 plating new plants, additions or improvements.

The General Magnesite an^ Magnesia Co., Philadelphia, 

 Pennsylvania, has issued for the convenience of rubber workers 

 a neat four-page loose-leaf folder of heavy celluloid containing 

 tables of factors for determining specific gravity of rubber 

 compounds. The first table gives the volume ratios correspond- 

 ing to unit weights, from one to nine, of the ordinary compound- 

 ing ingredients. Similarly the second table gives volume ratios 

 for unit weights from one to nine, corresponding to specific 

 gravities from 1.00 to 1.70. The use of these data is explained 

 by directions and calculated examples.
