THE INDIA RUBBER WORLD

with the United States de- 

 writes in La Chronique Colonialc, of 



THE VARIETIES OF 



Henry Pittier, connected now 

 partment of agriculture, 

 Brussels : 



"One fact which the interested public persists in ignoring and 

 which, however, has been scientifically proved, is the large number 

 of Castilloa species— a number which considered from the stand- 

 point of cultivation is not without some importance. Up to the 

 present time one species of Castilloa producing caoutchouc has 

 been recognized generally, viz., the C. elastica, and one other 

 which produces resinous latex which coagulates into a brittle 

 substance, slightly or not at all elastic, the C. tunu. 



"But, in fact, two very distinct types have been confounded 

 under the name of Castilloa elastica, one growing in the semi- 

 arid districts of Central America and the other flourishing in 

 the periodically rainy zones. The first type includes one or 

 perhaps two species, the Castilloa lactiflna and C. nicoyana of 

 Cook, the second having at least four species: the C. elastica, 

 of Mexico; the C. Costricana on the Atlantic coast of Nica- 

 ragua, Costa Rica and Panama ; C. carinata of western Colombia, 

 and C. Ulei of Brazil and Peru. The choice among these species 

 is far from being an indifferent matter when their cultivation 

 for industrial purposes is considered and which should be gov- 

 erned by climatic conditions of each locality. It is probably a 

 fact that an ignorance of this detail has been the cause of so 

 little success in certain attempts made in the Indies and in other 

 colonies, and future experiments will certainly be more encourag- 

 ing if this detail is taken into account." 



KUBBEE PLANTATION ACCESSORIES. 



There always will be small and medium sized rubber planta- 

 tions on which it may not pay to put up large coagulating 

 plants. For their use has been assembled on this page illus- 

 trations of utensils that have become recognized as desirable parts 

 of a planting outfit, though some of them may prove desirable on 

 even the largest rubber estates. As a rule, the cups and spouts 

 are made of heavy tin; the dippers, bowls and pans of steel 

 enameled with porcelain, and the sieves are made of heavy tin

SYSTEM OF TAPPING RUBBER TREES. 



An accompanying diagram relates to a system in which the 

 grooves to be cut in the rubber tree are first worked out. with 

 the distances and angles correct. The guide by which this is 

 elTected is a right-angled triangular 

 piece of tin, with two sizes about 17 

 inches each and the third 2 feet. 

 The grooves to be cut along the 

 sloping side of the triangle will then 

 be at an angle of 45 degrees to the 

 base, each groove 2 feet long and at 

 intervals of one foot, starting from 

 the base of the tree, up to a height 

 of s feet, and all leading into a 

 running down to within a few inches of the 

 ground level, a small tin spout being inserted at the lower end 

 of this vertical channel to convey the latex into the tin vessels 

 which are placed on the ground near the tree. 



A NEW LATEX CUP. 



A NEW type of latex cup that has many points in its favor, 

 if it is not too costly, is shown in the 

 accompanying illustration. The method 

 of fastening to the tree and the cover 

 are particularly good, and it should 

 find many friends amcng the planters. 

 United States patent No. 919.098 has 

 been granted for this invention to James 

 Webster, of Victorville, California. 



RUBBER PLANTING NOTES. 



At a special meeting of stockholders 

 of Manchester North Borneo Rubber, 

 Limited (Manchester, May 21), it was 

 voted to increase the capital from 

 £65,000 to iioo,ooo, to provide for 

 increasing the companies area 

 under rubber. The company is 

 planting tobacco largely as a tem- 

 porary crop. 



Rubber Estates of Johore, 

 Limited, began planting in March, 

 1907, and at the last annual 

 meeting (London, May 4), it was 

 reported that over 3,300 acres had 

 been placed under rubber. The 

 oldest rubber had cost to date 

 about liA los. [=$70.56] per acre. 

 Kautschuk-Plantage Moinbo, G. 

 m. b. H., has been registered at 

 Arnstadt, Germany, with a capital 

 of 510,000 marks [=$121,380], to 

 plant rubber at Mombo, in the 

 Wilhelmstal district, German East 

 Africa. It is formed to develop a 

 plantation already started by 

 Robert Trautmann, of Arnstadt, 

 and Gustav Weisfiog, of Erfurt, 

 Germany, who are the organizers 

 of the new company. 



Mr. H. A. Wickham, who will 

 be remembered in connection with 

 the original introduction of the 

 cultivation of Hevea rubber into 

 the Far East, is still active in
