On the last day of the last session of Congress, as appears by the Journal of the House of Representatives, "a joint resolution in regard to the carrying the United States mails from Saint Josephs, Missouri, to Placerville, California," was presented to me for my approval. This resolution authorized and directed the Postmaster-General "to order an increase of speed upon said route, requiring the mails to be carried through in thirty days, instead of thirty-eight days, according to the existing contract: _Provided_, The same can be done upon a _pro rata_ increase of compensation to the contractors." I did not approve this joint resolution: First, because it was presented to me at so late a period that I had not the time necessary on the day of the adjournment of the last session for an investigation of the subject. Besides, no injury could result to the public, as the Postmaster-General already possessed the discretionary power under existing laws to increase the speed upon this as well as all other mail routes. Second. Because the Postmaster-General, at the moment in the Capitol, informed me that the contractors themselves had offered to increase the speed on this route to thirty instead of thirty-eight days at a less cost than that authorized by the joint resolution. Upon subsequent examination it has been ascertained at the Post-Office Department that their bid, which is still depending, proposes to perform this service for a sum less by $49,000 than that authorized by the resolution. JAMES BUCHANAN. WASHINGTON CITY, _February 24, 1859_. _To the House of Representatives of the United States_: I return with my objections to the House of Representatives, in which it originated, the bill entitled "An act donating public lands to the several States and Territories which may provide colleges for the benefit of agriculture and the mechanic arts," presented to me on the 18th instant. This bill makes a donation to the several States of 20,000 acres of the public lands for each Senator and Representative in the present Congress, and also an additional donation of 20,000 acres for each additional Representative to which any State may be entitled under the census of 1860. According to a report from the Interior Department, based upon the present number of Senators and Representatives, the lands given to the States amount to 6,060,000 acres, and their value, at the minimum Government price of $1.25 per acre, to $7,575,000. The object of this gift, as stated by the bill, is "the endowment, support, and maintenance of at least one college [in each State] where the leading object shall be, without excluding other scientific or classical studies, to teach such branches of learning as are related to agriculture and the mechanic arts, as the legislatures of the States may respectively prescribe, in order to promote the liberal and practical education of the industrial classes in the several pursuits and professions in life."
