Frank R. Henderson, president. New York Rubber Exchange, last week accepted as fact a report of vast latex* production from rubber trees cultured in the Dutch East Indies. Buds of exceptional rubber trees had been grafted into trees that normally yielded but three or four pounds of rubber a year. After bud grafting the trees, by report, began to yield enormously, in some cases 100 pounds a year. At such report Arthur A. Judd, writer for the Chicago Journal of Commerce, scoffed: "The exchange president's report on the outcome of the experiment smacks of the fairy tale. Trees...

Rubber Co. has its own plantations in Oceana. Firestone Rubber Co. is trying to develop Liberian jungles. It has made little progress there so far. In their predicament U. S. rub ber manufacturers have five measures towards gaining some relief: 1) reclaimed rubber, 2) synthetic rubber, 3) factice, 4) mineral rubber, and 5) more economical meth ods of manufacture.

Selective breeding of plants that will grow out of the tropics, such as the wild guayule shrub of Texas and Mexico was recommended to U. S. manufacturers now endangered by Britain's rubber monopoly. Guayule does not contain rubber as latex (milky sap) but as small particles among its fibres. The shrub must be cut down and pulverized to extract these particles, less than a pound to each bush. None the less, President George H. Carnahan of the Continental Rubber Co., showed that guayule plantations totaling only 1,000 sq. mi. would supply 25% of this country...
