to-day to a communication to the Detroit Free Pres, over the signature of "L." discuseing the position oí the De mocraoy of the Dation, and the duties devolviog upon it in tb trying emergency of the governnient. Of the wriler, the Free Press says he is "one of the ablest men in the State," and of the letter we need only say that it expresse our own views of the present and future duties ol the Democracy better than ire could do it ourself. It is the true polioy oí the Democratie party to "let the dead past bury ita dead," and it is folly for it to make any effort to save an "institution" which was doomed by the South itself from the date of the passage of the first seeessiop. ordinance, or at least from the firing of the first gun at 8umpter. - The Southern leaders coolly and deliterately saeriSced the Democratie party that they might have an excuse in the eleotion of IíIncoln for secession. Aud is it wisdom in the Democracy to accept the sacrifica, and bury itseif beyond the hope of resurrection to save its treacherous Southern iriends from the legitímate fruits of their own acts? Our position is, and it certainly should be the position of the Democracy, let the rebelhon be put down and let slarery tak e the consefuencet. ÍD this we differ both from the secessionists of the Sout-h and the radicáis of the Korth. The South secoded that it might build up, unquestioned, D dave oligarchy. The radicáis of the North favored sucession that they might be sepnrated from sliivery, and have airned to so conduct the war as to secure the destruclion of the " peculiar institution,' even at the expense of the Union. The Democracy has no sympathy with either of these classes, and whoever would weep over the downfall of slavery and aid secession to save it, is no more a Denmcrat than he who would "let the Union slide " to kill it. Let the Democracy look living facts in the face, take tUngs as they are, aud go in for putting down the rebellion and restoring the Union ; and if the restored Union shall not be exactly " as it was," it will be the fault of those Southern leaders who broke up and defeated the Democratio party, and then made a foui aUetnpt to destroy the Uuion of wbich it was the bulwark. L3L The New York Tribunf in its leader announcing the result of the Baltimore Convention, and giving its adhesión, under protest, to the ticket, says : " We believe the rebellion would " have lost something of ita cohesión " and venom irom the hour in which it " was known that a new President " would surely be inaugurated on the " 4th of Match next." Eelieving ro, Horace Greelet and the Tribune advocatod the nominalion of another candidato than Abraham Lincoln. But tho " loyalty " of the Tribune to party exceeds ita love of the Union, and it supports Abraham Lincoln whilo it declares a belief that his defeat would cause tho " rebellion to loso soruethiug of its cohesión and venom.'' What say Union loving men f VVill they prolong the rebellion by reílectiiig Lincoln, or will they aid in depriving it of its " cohesión and venom"' by making it "known that a new President will be inaugurated on the 4th of March next?"
