Hundreds of thousands of acres in the white pine region, notably in Michigan, Wisconsin, and Minnesota, have been cut over, abandoned, sold for taxes, and finally reduced by fire to a useless wilderness because of the shortsighted policy of heavy taxation. To lay heavy taxes on timber land is to set a premium on forest destruction, a premium that is doing more than any other single factor to hinder the spread of conservative lumbering among the owners of large bodies of timber land. * * * Heavy taxes are responsible for the barrenness of thousands of square miles which should never have ceased to be productive, and which must now lie fallow for many decades before they can be counted again among the wealth-making assets of the nation. (Pinchot, _Agric. Yr. Bk._, 1898, pp. 184-185.) On the treatment of the questions of fire and taxes depends the future of American forest industries. (Bruncken, p. 226.) Undoubtedly much waste has been caused by sheer ignorance of forest conditions and methods, which, if followed, would secure successive crops instead of one, but it is safe to say that the desire for immediate profits has been the dominant cause of reckless lumbering. So short-sighted has the policy of private owners proved itself, that it is a question whether any large extent of forest land can safely be left in private hands. No individual lives long enough to reap more than one forest crop. Only corporations and States can be expected to have an interest long enough continued to justify the methods of conservative lumbering. As a matter of fact, nearly one-half of the privately owned timber of the United States is held by 195 great holders, the principal ones being the Southern Pacific Company, the Weyerhauser Timber Company, and the Northern Pacific Railway Company, which together own nearly 11 per cent. of the privately owned forests of the country. These large holders are cutting little of their timber, their object, however, being not so much to conserve the forests as to reserve to themselves the incalculable private profits which are expected to come with the future enormous increase in the value of timber. Over against this policy, stands that of the United States Forest Service of increasing the area of the National Forests in order to conserve them for the public welfare. The pity is that the government ever let the forests pass out of its hands. Only forty years ago seventy-five per cent. of the timber now standing was publicly owned. Now about eighty per cent. of it is privately owned. In the meanwhile its value has increased anywhere from ten to fifty fold, according to locality.[3] Some large corporations, however, like the Pennsylvania Railroad, the Kirby Lumber Company, of Texas, and the International Paper Company, have entered upon a policy of conservative lumbering.
