Charles Lathrop Pack, The School Book of Forestry
“ Forest experts say that the United States, which produces more than one-half of all the sawed timber in the world, should pay more attention to the export lumber business. Such trade must be built up on the basis of a permanent supply of timber. This means the practice of careful conservation and the replacement of forests that have been destroyed. We can not export timber from such meagre reserves as the pine forests of the South, which will not supply even the domestic needs of the region for much more than ten or fifteen years longer. ”
