Show SOURCE OF RUBBER SUPPLY New One Recently Has Been Found in Mexico in the Palo Amarillo Tree. City of Mexico. Another practical , and very extensive source of crude rubber supply was recently discovered In the vicinity of Guanajuato. It Is the palo amarillo tree, which grows wild in a broad scope of territory bor-bering bor-bering the Pacific coast and extending towardjS the interior as far as Guanajuato. Guana-juato. The commercial possibilities of this tree as a prpducer of rubber have been thoroughly tested by the Mexican Mex-ican government and by representatives representa-tives of large American interests that are investing considerable capital in the new industry. The palo amarillo tree bears no resemblance re-semblance to the guayule shrub from which large quantities of rubber are being manufactured in Northern Mex- y-ico y-ico and Southwestern Texas. This . y tree is also of a different species from' .. the rubber tree of the tropical regioij . of Mexico and other countries. It ,L-tains ,L-tains a height of about 30 feet. Its -trunk gets to be of a thickness of pne to two feet. The tree is of rapid growth, reaching a commercial size in five years. The news that the palo amarillo tree is being utilized for the manufac-ture manufac-ture of crude rubber has caused a number of independent rubber coiv cerns to enter the new field of Indus-" try, to the extent that they are activo- The Palo ATiarillo Tree. ly purchasing all the available tracts of trees in the territory that has not been invaded by the pioneer company. It is expected that a number of independent inde-pendent rubber .manufacturing plants, will be established during the next few months and that It will not be a great while until the palo amarillo industry in-dustry will rival that of guayule rubber, rub-ber, in which more than C5 millkm dollars gold has been Invested during the last few years. . With the assurance that the palo amarillo tree and the guayule shrub can be easily propagated and that their growth is adapted to a largo area of country I lie question of tho possible permanency of the rubber supply of the world is practically solved. |
