In the beginning of 1910 a revolt broke out in the Acre which 
may disturb trade for some time owing to the great distance from the 
normal military garrisons. 
The term “ rubber ” includes Para rubber, “wild” or “planta- 
tion,” a product containing qualities which may perhaps never be 
exactly reproduced in rubber in any other country or climate than 
that of the partly submerged Amazon forest. It also includes 
manipoba and mangabeira and other low-priced rubber, poor sub- 
stitutes for Para rubber, and for which no special use has been found. 
Meanwhile a great increase of raw material is in sight, and some 
626,000 acres planted with over 21,000,000 of trees in Malay and 
Ceylon are coming into bearing. 
From some estates and plantations in Brazil rubber may still be 
profitably exported owing to its special qualities, but from others the 
quality of the rubber is such, that, given the scarcity of labour and the 
heavy working expenses in Brazil, high taxation, &c., it cannot be 
profitably exported when prices fall to meet the Asiatic competition or 
to enable demand to keep pace with the already swelling production. 
The world’s consumption has risen from 50,000 tons in 1903 to 
68,000 tons in 1909. According to the statistics of Messrs. Figgis, the 
world’s supply was : —

The supply for 1910 has been estimated at about 74,000 tons. 
The supply of plantation rubber increased 100 per cent, in 1909 
over 1908, and this increase will be faster when the Asiatic plantations 
come into full bearing about 1910 and onwards.
