The census recently taken shows a regularly progressive increase in our population. Upon the breaking out of the War of the Revolution our numbers scarcely equaled 3,000,000 souls; they already exceed 17,000,000, and will continue to progress in a ratio which duplicates in a period of about twenty-three years. The old States contain a territory sufficient in itself to maintain a population of additional millions, and the most populous of the new States may even yet be regarded as but partially settled, while of the new lands on this side of the Rocky Mountains, to say nothing of the immense region which stretches from the base of those mountains to the mouth of the Columbia River, about 770,000,000 acres, ceded and unceded, still remain to be brought into market. We hold out to the people of other countries an invitation to come and settle among us as members of our rapidly growing family, and for the blessings which we offer them we require of them to look upon our country as their country and to unite with us in the great task of preserving our institutions and thereby perpetuating our liberties. No motive exists for foreign conquest; we desire but to reclaim our almost illimitable wildernesses and to introduce into their depths the lights of civilization. While we shall at all times be prepared to vindicate the national honor, our most earnest desire will be to maintain an unbroken peace. In presenting the foregoing views I can not withhold the expression of the opinion that there exists nothing in the extension of our Empire over our acknowledged possessions to excite the alarm of the patriot for the safety of our institutions. The federative system, leaving to each State the care of its domestic concerns and devolving on the Federal Government those of general import, admits in safety of the greatest expansion; but at the same time I deem it proper to add that there will be found to exist at all times an imperious necessity for restraining all the functionaries of this Government within the range of their respective powers, thereby preserving a just balance between the powers granted to this Government and those reserved to the States and to the people.
