Sir, our position is this: The United States finds itself the owner of a vast region of country at the west, now almost vacant of inhabitants. Parts of this region are salubrious and fertile. We have reason to suppose, that, in addition to the treasures of wealth which industry may gather from its surface, there are mineral treasures beneath it,--riches garnered up of old in subterranean chambers, and only awaiting the application of intelligence and skill to be converted into the means of human improvement and happiness. These regions, it is true, lie remote from our place of residence. Their shores are washed by another sea, and it is no figure of speech to say that another sky bends over them. So remote are they, that their hours are not as our hours, nor their day as our day; and yet, such are the wonderful improvements in art, in modern times, as to make it no rash anticipation, that, before this century shall have closed, the inhabitants on the Atlantic shores will be able to visit their brethren on the Pacific in ten days; and that intelligence will be transmitted and returned between the eastern and the western oceans in ten minutes. That country, therefore, will be rapidly filled, and we shall be brought into intimate relations with it, and, notwithstanding its distance, into proximity to it. Now, in the providence of God, it has fallen to our lot to legislate for this unoccupied, or but partially occupied, expanse. Its great future hangs upon our decision. Not only degrees of latitude and longitude, but vast tracts of time,--ages and centuries,--seem at our disposal. As are the institutions which we form and establish there, so will be the men whom these institutions, in their turn, will form. Nature works by fixed laws; but we can bring this or that combination of circumstances under the operation of her laws, and thus determine results. Here springs up our responsibility. One class of institutions will gather there one class of men, who will develop one set of characteristics; another class of institutions will gather there another class of men, who will develop other characteristics. Hence their futurity is to depend upon our present action. Hence the acts we are to perform seem to partake of the nature of creation, rather than of legislation. Standing upon the elevation which we now occupy, and looking over into that empty world, “yet void,” if not “without form,” but soon to be filled with multitudinous life, and reflecting upon our power to give form and character to that life, and almost to foreördain what it shall be, I feel as though it would be no irreverence to compare our condition to that of the Creator before he fashioned the “lord” of this lower world; for we, like Him, can ingraft one set of attributes, or another set of attributes, upon a whole race of men. In approaching this subject, therefore, I feel a sense of responsibility corresponding to the infinite,--I speak literally,--the _infinite_
