In many countries of Europe it has long been the policy of governments to retain ownership of all lands containing timber, minerals, oil, natural gas, phosphate, and water power. The products of these lands are extracted and put upon the market through a leasing system. That is; the user of the land pays to the State a rental according to the amount and quality of raw material which he takes from the storehouse of nature. Theoretically, the State could sell such lands at prices that would bring in as much revenue as does the leasing system; practically, this result has never been attained. The principal advantages of the leasing arrangement are: to prevent the premature destruction of forests, the private monopolisation of limited natural resources (which has happened in the case of the anthracite coal fields of Pennsylvania) and the private acquisition of exceptionally valuable land at ridiculously low prices; and to enable the State to secure just treatment for the consumer and the labourer by stipulating that the former shall obtain the product at fair prices, and that the latter shall receive fair wages. This example should be followed by the United States. All timber, mineral, gas, oil, and water power lands which have not been alienated to private persons should remain under government ownership, and be brought into use through a leasing arrangement which would enable the private operators to obtain the rates of profit and interest which are ordinarily yielded by enterprises subject to the same degree of risk. Happily this policy now seems likely to be adopted. In 1913 a law was passed by the United States providing for the operation of the coal mines of Alaska on leases. The amount that can be leased by any person or corporation is limited to 2560 acres, and the penalty for attempting to monopolise the product is forfeiture of tenure. The Secretary of the Interior has urged a similar arrangement for the development and extraction of water power, coal, oil, gas, phosphate, sodium, and potassium on the public domain of Continental United States, and his recommendation will probably be adopted by Congress. Thus the rent of these lands will go to the whole people instead of to a comparatively small number of individuals, monopoly of the products will be made impossible, and our remaining public resources will be protected from rapid and ruinous exploitation.
