This Chinese tree, which for a hundred years or more has been one of the popular street trees of New Orleans and other Southern cities, is creating some attention in California just now. It is believed that tallow can be obtained from these trees cheaper than the illuminating oils now used in light-houses and elsewhere. The colored candles used in the decorations of our Christmas trees, are said to be made from this wax. Can any of our New Orleans correspondents tell us of any experiments actually made there? The botanical name is Stillingia sebifera.
