The importance which I have attached to the establishment of a university within this District on a scale and for objects worthy of the American nation induces me to renew my recommendation of it to the favorable consideration of Congress. And I particularly invite again their attention to the expediency of exercising their existing powers, and, where necessary, of resorting to the prescribed mode of enlarging them, in order to effectuate a comprehensive system of roads and canals, such as will have the effect of drawing more closely together every part of our country by promoting intercourse and improvements and by increasing the share of every part in the common stock of national prosperity. Occurrences having taken place which shew that the statutory provisions for the dispensation of criminal justice are deficient in relation both to places and to persons under the exclusive cognizance of the national authority, an amendment of the law embracing such cases will merit the earliest attention of the Legislature. It will be a seasonable occasion also for inquiring how far legislative interposition maybe further requisite in providing penalties for offenses designated in the Constitution or in the statutes, and to which either no penalties are annexed or none with sufficient certainty. And I submit to the wisdom of Congress whether a more enlarged revisal of the criminal code be not expedient for the purpose of mitigating in certain cases penalties which were adopted into it antecedent to experiment and examples which justify and recommend a more lenient policy. The United States, having been the first to abolish within the extent of their authority the transportation of the natives of Africa into slavery, by prohibiting the introduction of slaves and by punishing their citizens participating in the traffic, can not but be gratified at the progress made by concurrent efforts of other nations toward a general suppression of so great an evil. They must feel at the same time the greater solicitude to give the fullest efficacy to their own regulations. With that view, the interposition of Congress appears to be required by the violations and evasions which it is suggested are chargeable on unworthy citizens who mingle in the slave trade under foreign flags and with foreign ports, and by collusive importations of slaves into the United States through adjoining ports and territories. I present the subject to Congress with a full assurance of their disposition to apply all the remedy which can be afforded by an amendment of the law. The regulations which were intended to guard against abuses of a kindred character in the trade between the several States ought also to be rendered more effectual for their humane object. To these recommendations I add, for the consideration of Congress, the expediency of a remodification of the judiciary establishment, and of an additional department in the executive branch of the Government.
