Our cotemporariesofthe St. Louis press, we f'ear, are preparing the way for other alrocities in ihat regiÃ³n, by their aciions with rcferencc to the four murderers hung there on the ninth. ,One of them lias writtcn out. printed in pamphlet forrn, and advertises for sale, the "Confession" of Madiaon and Brown, and anotker commends as a "painter of the first class," a Mr. Parker, vvho ''has luUen tho likenesea of the four characters, and wilt exhibit them for a few days, at the print shop of Mr. Wuolswhore those "who have nol seen the negroe.s," nre informed thafthey can have a siglu of IhÃ«ir exict likenesses." Expeneuce, we thÃnk, has shown coÃ±cÃusively, lÃ¯iat the habit which the n-et-s h.is of maUing lions of persons who Have been guihy f great crimes has a most perntcious nujence in society.- Among the low and ignorant, the impulse 10 becume liona too, is pilen stronger ihan they can resist. They lose sight of thÃ© penalty of crime, and see that itmakes"heroes" cifth'e guihy. Public executions are bnd enoiigli, buttliis lion making, alter the cord has done its work, is itifiinitely wor.so. - Cincinnuti Gaz. This business, however, was carried to a far greater pitch in the South West, where ihe papers are filled wiih narrativos, rcporl.s and reflertions respeciing thesci crimiÃ¼als. Tho N. Ã. AÃ¼vertiicr, Julv 20ih, 8ayj of.tne narrative of the j sions, &c. "E. V. Bronson, Es-q. has sent us a copy of the Confessions of those four eminent black murderers, Madison, Brown, VVarwick and Ãuward. The work is gollen up by Messrs. Chandler and Knapp, the cditors of the Si. Louis Republican, and well cxecuted it is in the styie of the confessions, vhicy are confined slrictly to a doiail of facts. It is absi.lutely interei-ting, and readers who would see howthe lavesteftlers of the South and the uboÃ¼lionists of the N(irth play their cards,would be itistructed by going to Cuma1, buying a copy, aml carcfuÃ¼y rcading it. We shutild be doing iujustice to the authors, diil we allempt k icautne of these thrilling confessions, but we cannot ayoid iudulging in the reflection ihat we have quite us much to dread from the machinations of ne;rotraders, as we have iÃ¯oui aboliliunistÃ¶.1' The next poiiit is the anxiety to idcntify these desperate murderers wiih the abojin lionials of ilie Nurth.

But the , ion oi' the "cpnlessions" has given the j vhole matter a new impulse. Whnt the , 'confessiuns" contain we know not, and )crhaps never shall know. The N. O. 3aily Picayune, of July 20h, feite the iolowiny terrible story on the subject. "The confession of Brown, a free negro, laces tlie country in possÃ©ssirtn hÃ¯ f'uct.s vhich tnay well cause pain and ustnnishnerit. Up to tuk day of his txecutiox, IK WAS TlfK RKCULARLY AUTUcniZKD lGext Ã¼f thk Ohio State Anti Sla vt tY Sociktv ! ! He was iirst engaged at l saliiry of $30 per month, bul was soun o eillcient in helping rumway slaves to ilaces of securily, thiit his wagts wcre aised to $50 per month. He was supilied with blank free papers, and came to iew Oileans, According to hia own itatement, he assiated away fiom Neto Orleans and the surrounding country, about Hghty slaves, and f rom Vickfburgh and 'he neigkboxfiQod, sixteen more!

' We odnfess there is something exceedngly starlling in the statements - the ease md facility with which slaves are en'.iced j.way by these black-hearted abolilion cmissaries, and the almost perfect impuntti' witii which theirschemes are carried inlo execution, may well cause alarm. - VVluin one man has ai:led one hundred lo ec;;po, and has not even been suspected, uulil the secret has been divulged upon (hÃ¨gallowSj it s indeed time for the adoption of precautionarv measures that wil] fully reach the evil." 'l'hc St. Louis correspondent of tho same paper, afler giving an account of the execulion, says: "A clergymen of this city, noted more for ardor than any particular enlargemcni ot' mental or moral facullies, ha6 made a feeble attempt to remove the evidence of connedion bet ween these scoundrels and the Abolition Society; but the only effect of his letter has been to place hitn in a oosition before the people of allsluveholding States, which can scarcely be very gratifying for him to reflect upon or confortable to rest on. Your wrÃter has beun bbown a letter writlen by one of the convicta lo a noted abulilioni9t of New York, which contaius such damning evj dence of thisconnection as cannot be djturbed by ALLTHEPIOUS CII1CANE RY ANDSANC TIMONIOUS HUMHUG THAT THIS PEST1FEROUS PARTY OF D1SORGANIZING FANATICS CAN RAKE TOGETHER"! ! Now it may be, that one of the convicts has written a letter to a noied abolitionist in New York - but does that provo any thing? It may be, that Brown has helped off a hundred slaves up ihe Mississippi river, but that Ã³rily proves ihe facility and security wit which the thing is done. - And the puhlication of the tact through the country bordering on ihat river, will awaken groat interest, and perhnps tend greatly to the future aecurity of that species of property - perhaps awaken among the slaves aome new ideas Ã¶f hope. But Brown never va? en ngent oftheOhio Anti-Sluvery Society; the Arni-Siavery Societies have nosÃ¼ch agents; ;ant none, need none. The VigilarvcÃ« GÃ¶mnÃ¯ittÃ«ea, ihat take charge ol' the cases of persons ileeing from unjust bondage, havo tiÃ¶sÃ¼ch ngents, they have always had tnoie cases to atlend to without agents, thati their tneans werc cqual to. lf BrÃ¶wri has'donÃ© the deeda he boastÃ«d uf, he was Ã©'htifÃ³ly self-rnoved, :md the record of lÃºa life only serves lo show the slaveholdera one more ofihe diiTicuitics with which they are beset in mainlaining the permanence Ã³f their "insiitution."
