=Cultivation of India Rubber.=--An article in the Bulletin of the Bureau of American Republics represents that there are lands in Mexico and Central America equally adapted to the cultivation of the India-rubber tree with the Brazilian plantations, and having, in addition, a salubrious climate. Formerly dependence for the supply of India rubber was placed in the product of wild trees, but with the increase in the uses for it, and the consequent rise in prices, capital is being invested in this industry, and its profitable cultivation is being largely engaged in. The trees do not flourish at an elevation exceeding five hundred feet above sea level, and low land, moist but not swampy, is the best. Land suitable for planting could be bought for twenty-five cents an acre in large tracts, but it now brings from two dollars to five dollars Mexican. These lands can be used for other crops while the trees are growing up, and thus made partly to repay the cost of starting the plantation. So the expense of clearing the land preparatory to planting it is largely met, if facilities for transplantation are at hand, by the sale of the dyewoods, sandalwood, satinwood, ebony, and mahogany that are cut off. The land should be chosen along the banks of streams, where the soil is rich, deep, and loamy, and the presence of wild rubber trees is a sure indication of its suitability. These wild trees should be left standing, and young seedlings should be kept and transplanted into their proper places. The densest plantation compatible with good results is fifteen feet apart, giving about one hundred and ninety-three trees to the acre. Once in the ground, the tree needs no attention or cultivation beyond keeping down the undergrowth, which can be effected by the aid of a side crop. The tree propagates itself by the seeds or nuts, which drop in May and June. By the sixth or seventh year the grove will be in bearing, and thereafter should yield from three to five pounds of India rubber per tree. * * * * *
