15/18 The Forest Service estimates that by protecting our cut-over and waste lands from fire and practicing care to secure reproduction after logging on our remaining virgin forest land, we can produce annually at least 27,750,000,000 cubic feet of wood, including 70,000,000,000 board feet of sawtimber. Such a production would meet indefinitely the needs of our growing population, and still leave an amount of timber available for export. Ten per cent of our yearly cut of valuable white oak is shipped overseas. At the present rate of cutting, the supply, it is said, will not last more than twenty-five years. We ship abroad about seven per cent. |
