He tells us jurisdiction was exercised between the two rivers, but he does not tell us it was exercised over all the territory between them. Some simple-minded people think it is possible to cross one river and go beyond it without going all the way to the next, that jurisdiction may be exercised between two rivers without covering all the country between them. I know a man, not very unlike myself, who exercises jurisdiction over a piece of land between the Wabash and the Mississippi; and yet so far is this from being all there is between those rivers that it is just one hundred and fifty-two feet long by fifty feet wide, and no part of it much within a hundred miles of either. He has a neighbor between him and the Mississippi--that is, just across the street, in that direction--whom I am sure he could neither persuade nor force to give up his habitation; but which nevertheless he could certainly annex, if it were to be done by merely standing on his own side of the street and claiming it, or even sitting down and writing a deed for it.
But next the President tells us the Congress of the United States understood the State of Texas they admitted into the Union to extend beyond the Nueces. Well, I suppose they did. I certainly so understood it. But how far beyond? That Congress did not understand it to extend clear to the Rio Grande is quite certain, by the fact of their joint resolutions for admission expressly leaving all questions of boundary to future adjustment. And it may be added that Texas herself is proven to have had the same understanding of it that our Congress had, by the fact of the exact conformity of her new constitution to those resolutions.
I am now through the whole of the President's evidence; and it is a singular fact that if any one should declare the President sent the army into the midst of a settlement of Mexican people who had never submitted, by consent or by force, to the authority of Texas or of the United States, and that there and thereby the first blood of the war was shed, there is not one word in all the which would either admit or deny the declaration. This strange omission it does seem to me could not have occurred but by design. My way of living leads me to be about the courts of justice; and there I have sometimes seen a good lawyer, struggling for his client's neck in a desperate case, employing every artifice to work round, befog, and cover up with many words some point arising in the case which he dared not admit and yet could not deny. Party bias may help to make it appear so, but with all the allowance I can make for such bias, it still does appear to me that just such, and from just such necessity, is the President's struggle in this case.
Sometime after my colleague [Mr. Richardson] introduced the resolutions I have mentioned, I introduced a preamble, resolution, and interrogations, intended to draw the President out, if possible, on this hitherto untrodden ground. To show their relevancy, I propose to state my understanding of the true rule for ascertaining the boundary between Texas and Mexico. It is that wherever Texas was exercising jurisdiction was hers; and wherever Mexico was exercising jurisdiction was hers; and that whatever separated the actual exercise of jurisdiction of the one from that of the other was the true boundary between them. If, as is probably true, Texas was exercising jurisdiction along the western bank of the Nueces, and Mexico was exercising it along the eastern bank of the Rio Grande, then neither river was the boundary: but the uninhabited country between the two was. The extent of our territory in that region depended not on any treaty-fixed boundary (for no treaty had attempted it), but on revolution. Any people anywhere being inclined and having the power have the right to rise up and shake off the existing government, and form a new one that suits them better. This is a most valuable, a most sacred right--a right which we hope and believe is to liberate the world.
