Actual settlers under existing laws are protected against other purchasers at the public sales in their right of preemption to the extent of a quarter section, or 160 acres, of land. The remainder may then be disposed of at public or entered at private sale in unlimited quantities.

Speculation has of late years prevailed to a great extent in the public lands. The consequence has been that large portions of them have become the property of individuals and companies, and thus the price is greatly enhanced to those who desire to purchase for actual settlement. In order to limit the area of speculation as much as possible, the extinction of the Indian title and the extension of the public surveys ought only to keep pace with the tide of emigration.

If Congress should hereafter grant alternate sections to States or companies, as they have done heretofore, I recommend that the intermediate sections retained by the Government should be subject to preemption by actual settlers.

It ought ever to be our cardinal policy to reserve the public lands as much as may be for actual settlers, and this at moderate prices. We shall thus not only best promote the prosperity of the new States and Territories and the power of the Union, but shall secure homes for our posterity for many generations.

The extension of our limits has brought within our jurisdiction many additional and populous tribes of Indians, a large proportion of which are wild, untractable, and difficult to control. Predatory and warlike in their disposition and habits, it is impossible altogether to restrain them from committing aggressions on each other, as well as upon our frontier citizens and those emigrating to our distant States and Territories. Hence expensive military expeditions are frequently necessary to overawe and chastise the more lawless and hostile.

The present system of making them valuable presents to influence them to remain at peace has proved ineffectual. It is believed to be the better policy to colonize them in suitable localities where they can receive the rudiments of education and be gradually induced to adopt habits of industry. So far as the experiment has been tried it has worked well in practice, and it will doubtless prove to be less expensive than the present system.

The whole number of Indians within our territorial limits is believed to be, from the best data in the Interior Department, about 325,000.

The tribes of Cherokees, Choctaws, Chickasaws, and Creeks settled in the Territory set apart for them west of Arkansas are rapidly advancing in education and in all the arts of civilization and self-government, and we may indulge the agreeable anticipation that at no very distant day they will be incorporated into the Union as one of the sovereign States. It will be seen from the report of the Postmaster-General that the Post-Office Department still continues to depend on the Treasury, as it has been compelled to do for several years past, for an important portion of the means of sustaining and extending its operations. Their rapid growth and expansion are shown by a decennial statement of the number of post-offices and the length of post-roads, commencing with the year 1827. In that year there were 7,000 post-offices; in 1837, 11,177; in 1847, 15,146, and in 1857 they number 26,586. In this year 1,725 post-offices have been established and 704 discontinued, leaving a net increase of 1,021. The postmasters of 368 offices are appointed by the President.

The length of post-roads in 1827 was 105,336 miles; in 1837, 141,242 miles; in 1847, 153,818 miles, and in the year 1857 there are 242,601 miles of post-road, including 22,530 miles of railroad on which the mails are transported.

The expenditures of the Department for the fiscal year ending on the 30th June, 1857, as adjusted by the Auditor, amounted to $11,507,670. To defray these expenditures there was to the credit of the Department on the 1st July, 1856, the sum of $789,599; the gross revenue of the year, including the annual allowances for the transportation of free mail matter, produced $8,053,951, and the remainder was supplied by the appropriation from the Treasury of $2,250,000 granted by the act of Congress approved August 18, 1856, and by the appropriation of $666,883 made by the act of March 3, 1857, leaving $252,763 to be carried to the credit of the Department in the accounts of the current year. I commend to your consideration the report of the Department in relation to the establishment of the overland mail route from the Mississippi River to San Francisco, Cal. The route was selected with my full concurrence, as the one, in my judgment, best calculated to attain the important objects contemplated by Congress.
