Tribune. Lkxingtom, Ky. March 20, 1844 W. J. M'Kikkky, Esq., May 'ir of Dayton, Ohio: Dear S(r - Yonr leHer of Fcbnmry 15th lost, was in due time recevved, and I liave woited thns with Ihn intention of not answennj; it Qt olí r becatise nam a private citizfn, not seekinof office at the hands of the penple, it miht place me in the p'efsumptüoifs atlitndO of atlempting to ir.fluance, by mere weipht of opinión, the votes of my countrymen in their choie of President: when neither my nge, oxpeiience or fame wnrranted the asstimption. But since the reception of yotir Jpttor, I have received mony of eimilar import, from Liberty men nnd anli-slavery Whig, in most of the Northern States, pressing upon me on expression of opinión, ju such a mnnner that I should prove fnlse to tliat epirit of candcr Rfhich I proudly cherish as chnracteristic of Uie principies 1 advocate, did I, through my aöectution of hnmtlity, remain Ionger silent. You ask me, 'Will yon, if yon live and are uble to voie at the noxt Pre3Ídontial election, vote for Henry CJay for Present? If thethird party, or Liberty men, should have an electoral ticket in your State, would you yote that ticket 'm preferRiice? VVere you a citizen of Oliio, which of these tickets would you vote?' The hst two questions are such aa.uu iMjuire vanous ot ner supposjlions to b matle before I conlti give a suitable answer in juslice to myseJf and all the olhcr partic concerr.ed, wJiich would be too Toluminous for the space of u single letter: and, for all: praclira] purpose?, they will besuffici'ently answcred in my reply to the first question: that, It is my most decidid dctcnninotion to 'vott for Uer.nj Ctuyfor President: Men never have, and never will, in all case?, tbink olike: a!l governraeiit is necessarily a sacnfice, to some extenr, of individual wül: that is thö best governnient" lo each individual which fosters or ajlöws Ihe most of whnt that individua] belisvrs ro be conducive to h$ beat intore&is. Tlie quesüon then snot, 'Can I find some man to vote for tirnong aeventeen mil!ionp, who thinks in all respecta es myselít but, 'Who is the man, nll thing-s present and remóte considered, ibat tvili most probablv be ablo by success to gfive effectuntion to thoe grent meosures which I deern conducive to my welfare, nnd !he welfare of my whole country?' This qncsljon cvery voter in ihe republic must determine for himself. For myself, after looking on all the turrounding circumsïances, conscience, pairiotism and (if other prefcr the term) enlightened s!' interest, constrain me t vote for Henry Clay. Tlie Tanfi; the Cunency, the Lands, Economy Executive aad Ministerial respon.-ibilin-,. and many oiher inlerests, nl) depend, in mybJejiHlgmf.'ut, on Mr. Clas clection for bencficial (e;e:ii)in;Uion. And iï he is elected, the decisión of 1, 40, passed by the people, wiU bc confirmed, and the policjt of the country seiticd. Thon. and (such ii the onarchy of Ihe public mind} nol till then, shall we have timeto lock about üs, nnd project that 01 her gvoat reform, the recluction of American slavery to its constittuioual limiis, and to coii('ontrate the uniteó comlerrmntion of the civilized world to ita iiiwl and ulier extinction. Mr. Clay is indeed a slaveholder - I wish he were nol. Yet it does not become me, who Imve so la!eJy t-a.sed lo be a slaveholder myself, io condemn kin, It remains for posterity to deternjine J)ow much shall be due him for the glorious impulse !iis fervent spirit haa given to Jiberty throughout the world: and with tlicm also to eay, ho'v much sha)) be subtracted from this npprecintion, for his liaving cm!y failedto do all that couid bedone in ihis holy canse.
