We have nothing published yet with special reference to the Taylor race; but we soon will have, and then I will send them to everybody. I made an internal-improvement speech day before yesterday, which I shall send home as soon as I can get it written out and printed,--and which I suppose nobody will read. Your friend as ever, A. Lincoln. Washington, July 10, 1848. Dear William,--Your letter covering the newspaper slips was received last night. The subject of that letter is exceedingly painful to me; and I cannot but think there is some mistake in your impression of the motives of the old men. I suppose I am now one of the old men; and I declare, on my veracity, which I think is good with you, that nothing could afford me more satisfaction than to learn that you and others of my young friends at home were doing battle in the contest, and endearing themselves to the people, and taking a stand far above any I have ever been able to reach in their admiration. I cannot conceive that other old men feel differently. Of course, I cannot demonstrate what I say; but I was young once, and I am sure I was never ungenerously thrust back. I hardly know what to say. The way for a young man to rise is to improve himself every way he can, never suspecting that anybody wishes to hinder him. Allow me to assure you that suspicion and jealousy never did help any man in any situation. There may sometimes be ungenerous attempts to keep a young man down; and they will succeed, too, if he allows his mind to be diverted from its true channel, to brood over the attempted injury. Cast about, and see if this feeling has not injured every person you have ever known to fall into it. Now, in what I have said, I am sure you will suspect nothing but sincere friendship. I would save you from a fatal error. You have been a laborious, studious young man. You are far better informed on almost all subjects than I have ever been. You cannot fail in any laudable object, unless you allow your mind to be improperly directed. I have some the advantage of you in the world's experience, merely by being older; and it is this that induces me to advise. You still seem to be a little mistaken about "The Congressional Globe" and "Appendix." They contain _all_ of the speeches that are published in any way. My speech and Dayton's speech, which you say you got in pamphlet form, are both, word for word, in the "Appendix." I repeat again, all are there. Your friend, as ever, A. Lincoln. The "internal-improvement" speech to which Mr. Lincoln alludes in one of these letters was delivered on the 20th of June, and contained nothing remarkable or especially characteristic. It was in the main merely the usual Whig argument in favor of the constitutionality of Mr. Clay's "American System."
