THE INDIA RUBBER WORLD 



[August i, 1904. 



trunk of the tree to swell very greatly, a tree that has been 

 much tapped assuming bottle form, tripling and quadrupling its 

 diameter. As the tapping goes on scar is inflicted on scar and 

 there comes a time when the milk no longer flows, but merely 

 trickles or oozes out. Then it is no longer practicable to colleet 

 the milk from the hundreds of small cups into a single recept- 

 acle, and it is allowed to slowly ooze and coagulate in the cups. 

 The result is Cameta rubber; or, as my informant put it: 

 "Cameta rubber is the kind of rubber you get from old, tired 

 out trees." 



It is this man's belief that if those same trees were allowed 

 to remain quiet for some years they would recover much of 

 their former productiveness, except where they have been in- 

 jured beyond remedy. He believes that if trees are carefully 

 tapped, so that the minimum of injury is inflicted, and are not 

 too heavily drawn on, they will continue to give practically the 

 same amount of latex annually for an indefinite time. 



If it should be found hereafter that districts which now yield 

 both fine and coarse rubber come to yield only Cametd.a posi- 

 tive factor in the determination of the probable future of rubber 

 production would be attained. The whole question is of great 

 interest and should be studied.

Editorial Note. — The above suggestions appear quite com- 

 patible with the following reference to " Cameta rubber " in 

 Mr. Pearson's " Crude Rubber and Compounding Ingredients :" 



Cameta rubber is so called from the port of that name, on the Tocan- 

 tins river. It is noted for the superior quality of its "sernamby" 

 grade, the " fine " being the same as from the Islands, but rarely seen. 

 This rubber comes in the form of little cups pressed into large "negro- 

 heads." 



At times the quotations for Cameta coarse rubber have been 

 materially higher than for Islands coarse, though never equal 

 to Upriver. Of late, however, Cameta and Islands coarse have 

 been quoted frequently at the same figures. During the past 

 three years Cameta rubber has averaged 2 cents per pound 

 more than Islands coarse at New York.

AMAZON CABLE INTERRUPTIONS. 



ANNOUNCEMENT was made on July 20 of the interrup- 

 tion of the cable service between Para and Manaos, 

 above Itacoatiara. Such interruptions are so frequent as no 

 longer to possess any novelty, and the service is so irregular as 

 to rob the cable of half its value to commerce on the Amazon. 

 The Amazon Telegraph Co., Limited, though put to heavy ex- 

 pense for several years past in keeping their cable in repair, 

 may not be aware of the cause of the interruptions, as ex- 

 plained to The India Rubber World by Captain Arthur 

 Schindelar, a gentleman of long residence and wide observa- 

 tion on the Amazon. According to this authority it is desir- 

 able, in the manipulation of rubber prices by the speculative 

 merchants at Para, to keep buyers of rubber ignorant, as far 

 as possible, of conditions upriver. Hence, whenever prices are 

 to be moved up a few points, the Amazon cable is cut, and de- 

 ceptive reports are distributed regarding a shortage of stocks 

 at Manaos. This gentleman does not claim to have seen per- 

 sonally any cutting of the cable. Captain Schindelar, by the 

 way, is now visiting the United States for the purpose of in- 

 teresting capital in a plan for controlling the rubber trade of 

 the Amazon.
