A question embracing such important interests and so well calculated to enlist the feelings of the people in every quarter of the Union has very naturally given rise to numerous plans for the improvement of the existing system. The distinctive features of the policy that has hitherto prevailed are to dispose of the public lands at moderate prices, thus enabling a greater number to enter into competition for their purchase and accomplishing a double object--of promoting their rapid settlement by the purchasers and at the same time increasing the receipts of the Treasury; to sell for cash, thereby preventing the disturbing influence of a large mass of private citizens indebted to the Government which they have a voice in controlling; to bring them into market no faster than good lands are supposed to be wanted for improvement, thereby preventing the accumulation of large tracts in few hands; and to apply the proceeds of the sales to the general purposes of the Government, thus diminishing the amount to be raised from the people of the States by taxation and giving each State its portion of the benefits to be derived from this common fund in a manner the most quiet, and at the same time, perhaps, the most equitable, that can be devised. These provisions, with occasional enactments in behalf of special interests deemed entitled to the favor of the Government, have in their execution produced results as beneficial upon the whole as could reasonably be expected in a matter so vast, so complicated, and so exciting. Upward of 70,000,000 acres have been sold, the greater part of which is believed to have been purchased for actual settlement. The population of the new States and Territories created out of the public domain increased between 1800 and 1830 from less than 60,000 to upward of 2,300,000 souls, constituting at the latter period about one-fifth of the whole people of the United States. The increase since can not be accurately known, but the whole may now be safely estimated at over three and a half millions of souls, composing nine States, the representatives of which constitute above one-third of the Senate and over one-sixth of the House of Representatives of the United States.
