But the gold-bearing regions covered by our Mexican acquisitions created a new dispensation in mining, and invited the attention of Congress to the consideration of a new and exceedingly important question. How should these mineral lands be disposed of? They covered an area of a million square miles, and their exploration and development became a matter of the most vital moment, not only in a financial point of view, but as a means of promoting the settlement and tillage of the agricultural lands contiguous to the mineral deposits. President Fillmore, in his message of December 2, 1849, recommended the sale of these lands in small parcels, and Mr. Ewing, his Secretary of the Interior, urged upon Congress the consideration of the subject, and recommended the policy of leasing them; but no attention seems to have been given to these recommendations. By Act of Congress of September 27, 1850, mineral lands in Oregon were reserved from sale; and by Acts of March 3, 1853, and of July 22, 1854, they were reserved in California and New Mexico. This was the extent of Congressional action. Early in the late war, the Secretary of the Interior, Hon. Caleb B. Smith, referred to the question, and the Commissioner of the General Land Office afterward repeatedly recommended the policy of leasing, but Congress took no notice of the subject. My interest in the question was first awakened in the fall of 1864, in carefully overhauling our land policy. Our mineral lands for more than sixteen years had been open to all comers from whatever quarter of the globe, during which time more than a thousand million dollars had been extracted, from which not a dollar of revenue reached the National Treasury save the comparatively trifling amount derived from the Internal Revenue tax on bullion. This fact was so remarkable that it was difficult to accept it as true. The Government had no policy whatever in dealing with these immense repositories of national wealth, and declined to have any; for a policy implies that something is to be done, and points out the method of doing it. It had prohibited the sale of mineral lands, and then come to a dead halt. The Constitution expressly provides that Congress shall have power "to make all needful rules and regulations respecting the territory or other property belonging to the United States"; but Congress, in reserving these lands from sale and taking no measures whatever respecting their products, simply abandoned them, and, as the trustee of the Nation, became as recreant as the father who abandons his minor child.
