To Horace Greeley 
Friend Greeley: In the ``Tribune'' of yesterday I discovered a little editorial paragraph in relation to Colonel Wentworth  of Illinois, in which, in relation to the boundary of Texas, you say: ``All Whigs and many Democrats having ever contended it stopped at the Nueces.'' Now this is a mistake which I dislike to see go uncorrected in a leading Whig paper. Since I have been here, I know a large majority of such Whigs of the House of Representatives as have spoken on the question have not taken that position. Their position, and in my opinion the true position, is that the boundary of Texas extended just so far as American settlements taking partPage 494 in her revolution extended; and that as a matter of fact those settlements did extend, at one or two points, beyond the Nueces, but not anywhere near the Rio Grande at any point. The ``stupendous desert'' between the valleys of those two rivers, and not either river, has been insisted on by the Whigs as the true boundary.
Will you look at this? By putting us in the position of insisting on the line of the Nueces, you put us in a position which, in my opinion, we cannot maintain, and which therefore gives the Democrats an advantage of us. If the degree of arrogance is not too great, may I ask you to examine what I said on this very point in the printed speech I send you. Yours truly, A. LINCOLN.
