The present system of managing the mineral lands of the United States is believed to be radically defective. More than 1,000,000 acres of the public lands, supposed to contain lead and other minerals, have been reserved from sale, and numerous leases upon them have been granted to individuals upon a stipulated rent. The system of granting leases has proved to be not only unprofitable to the Government, but unsatisfactory to the citizens who have gone upon the lands, and must, if continued, lay the foundation of much future difficulty between the Government and the lessees. According to the official records, the amount of rents received by the Government for the years 1841, 1842, 1843, and 1844 was $6,354.74, while the expenses of the system during the same period, including salaries of superintendents, agents, clerks, and incidental expenses, were $26,111.11, the income being less than one-fourth of the expenses. To this pecuniary loss may be added the injury sustained by the public in consequence of the destruction of timber and the careless and wasteful manner of working the mines. The system has given rise to much litigation between the United States and individual citizens, producing irritation and excitement in the mineral region, and involving the Government in heavy additional expenditures. It is believed that similar losses and embarrassments will continue to occur while the present system of leasing these lands remains unchanged. These lands are now under the superintendence and care of the War Department, with the ordinary duties of which they have no proper or natural connection. I recommend the repeal of the present system, and that these lands be placed under the superintendence and management of the General Land Office, as other public lands, and be brought into market and sold upon such terms as Congress in their wisdom may prescribe, reserving to the Government an equitable percentage of the gross amount of mineral product, and that the preemption principle be extended to resident miners and settlers upon them at the minimum price which may be established by Congress.
