Utica, June 22, 1&48. The Proceedings of the B mburncrs' Convention on the First Day. It is proper to suppose the deepest interest is f.'it by til- American public in all the movements of that heretic section of the democratic party as barnburners. The eyes or the South, urid the eyes of the North, are centred upon Utica, j the semi-national rendezvous of the intractable j demjcricy. Bat the barnburners have declared i that " NTo p?nt up Utioa contracts our power* ; The whole boundless continent Is ours." They have boldly declared in their addresses, their ; resolutions, and their letters, that a powerlul and watchful party has been organized at the North, which extends over the entire Northern portion ol this continent. Tins party, infuriated by the contumely with which its leaders have been treated? maddened by the disasters which it has suffered? is prepared to make a mighty and resistless oppemtion to the election of the nominees presented to the country by the Baltimore Convention. The first day's proceedings of the Convention have been deeply interesting and impressive. The Convention, in point of numerical force, ! mental energy and personal dignity, will compare favorably with any deliberative body that ever uscembled in America. The unanimity of feeling exhibited inth.s Convention is almost unparalleled ; the cntuusiasin ot the delegates, and of the people, who assembled to witness the deliberations of this body, is certainly great and certainly sincere. Tne early part of the day was occupied by the Convention i n recei ving the credentials of the delegates, and in appointing the usual committees.? In the afternoon, the Hon. Samuel young was elected President. This gentleman, on assuming the chair, delivered a short address, which will he found in the accompanying report of the proceedings. At a late hour, the Convention was addressed by Messrs. Smith, King, Grover, Van Buren, Butler, and Field. Their speeches were very piquant, and the enthusiasm of the audience went beyond all bounds. Mr. Butler read the long expected letter from Martin Van Buren. It is reallv a masterlv let it, and Mr. Van Karen says, in a private letter, that it may be the last one he shall ever write ; he is therelore anxious that it shall be printed correctly, and his anxiety upon this point nus made him guilty ot a great impropriety. He gave orders that it should not be published unless the proof sheets wyre read by himself, or by one of his bosom friends, whom it is not necessary to name. This order was highly improper, because it does not give liini a chance to compete with the he'y alliance. Mr. Van Buren ought to have been aw.?re that no document of this character was ever printed incorrectly in the Herald. The next time he m iv go to the dogs with his letters. This evening the democracy were addressed from the steps of Kugg'a hotel by Messrs. Smith, of Wayne : Nye of Madison; Taylor, of Ohio; Casserly, of New York ; Strong, of Wisconsin. T-morrow, Martin Van Kurcn will be nominated for President. There is no doubt on this point. The Convention will meet at 8 o'clock tomorrow morning. Hen v Dodge, of Wisconsin, will be nominated for Vice President. Uric*, June 22, 1948.

The tournamenthasopened. The Sikhsare here; the Mahomntedans are here; John Van Buren is here. Ttie morning is bright, and clear, and pleasant, and nature has been bounteous to the barnburners. The Convention assembled in the Methodist church on Bleccker street. Baggs' Hotel is the headquarters ot the delegates, and at a quarter to twelve o'clock they started for the church in a body. The building is of medium siite, and it is rendered memorable from the fact, that the last and latest Convention of the barnburners was held within its walls. At five minutes to twelve o'clock the head of the procession entered the church, and the sovereigns made a simultaneous rush for the galleries ; there are galleries at the sides, and also at the ends of the building. About two thousand persons were, present, and tho church was well filled ; the sovereigns in the galleties maintained a standing position. John Van Buren brought up the rear of the procession, and on entering the church he look ase it at the foot of the altar :niss?-at was humbl-, mid his attitude was humble and eancti I n-a ii-* iO"K?';i a* blooming as ne did hetore hp c mmencfd ofl'ensive operations; he wore a claret colored Pock coat, light brown waistcoat, and p <ntd of ihc same material. Jolm never wears a shirt collar, because, when he was in Europe, a draper of Pall Mall in London told him, tint a shirt collar w is considered to be a yoke by the ancients; the moderns (so fnr as the barnburners nre concerned) have a peculiar horror of yokes of stnv kind. I'll? appearance of the delegates, when they had assembled, was very good ; they nre generally men of talent and influence in their respective counties At 12 M.,the Hon. Ward Hunt, of Utica, calied the Convention to order. On motion of Simeon B Jeweii, Esq., the Hon. Thomas Furring on (late Treasurer) of Tioga, was ap;>ointed teni;>orary President. Mr. F., on assuming the ohair, snid:? It was unexpected thnt lie should be called upon to preside over till? Convention : he asked the indulgence of the delegate? wli lo he endeavored to discharge the dutluH of the Chair in an Impartial manner. Mr. F. is a fine looking man, and an accomplished man ; the selection is n good one. On motion of Mr. Pierce of Dutchess, Messrs. Dsnn and Surugham were appointed Secretmies. On rnotion of Joh n B. Miller. Esq. of Utica, the Secretaries wore instructed to call the several counties in alphabetical order, and the names of delegates representing the several counties. Mr. Vandyke, of the Album,/ Atlas, observed, ill it after some trouble lie had succeeded in making n list of the delegates, winch he believed was correct ; the paper, he said, was at the service of the Convention. The Secretary then proceeded to call the names ui me rr-^uiiu uriryiucw, lugeirmr wun ino norior/iry delii/atea from the several counties. The following list includes only the regular delegates: .dlltany ? Modern. Hareourt, Van Dyke, Benton! Stewart ,'llleghani/?Martin Grovcr. Broome ? S. VV. Hand. Callaraugue? Chautauyne? Franklin H.

A considerable tiine tvas occupied in calling over aud completing the list of delegates. It was amended and curtailed, and elongated in many ways. This list includes only the regular delegates. Those called honornry are not inserted. When the names were called, the President announced that all the counties in the State were represented except the counties of Rockland and Cattaraugus. Mr. Anoei.i,, of Livingston, said lits was informed that the young and vigorous State of Wisconsin had sent two delegates to this Convention. He moved that they be admitted to seats. The motion was adopted by acclamation. Mr. Townsexu said that Marcus Morton, Jr., of Massachusetts, a son of that distinguished (cheers and applause,) citizen who was well known to this convention, was present. He moved that he be admitted to a seat. The motion was unanimously adopted. On motion of the Hon. B. Bailky, of Putnam, Jani"3 W. Taylor, Esq , of Cincinnutti, Ohio, was admitted to a sent Delegates from Connecticut were also admitted, and then the further calling of names of delegates VU dispensed with. On motion of Judge Hoohboom, of Columbia, it was resolved that the delegates of such assembly districts as were represented by more than one delegate, should designate one ot their number to vote in the convention. On motion of Hon. B. Bailey, two delegates from eacit judical district in the State were appointed to report the names of permanent officers for the Convention. An effort was made to have the delegates from other States participate in these proceedings. but James W. Taylor, Esq., ot Ohio, 011 behalf of the delegates from other States said, That while thoy would uot withhold their sympathy, they would dvoliae to participfttw In the proceedings of the Convention. The democracy of other States, he said, would ratify the proceedings hereafter. (Applause j The motion t? have the delegates from other States placed upon theeom.-nittee 011 organization, was withdrawn. On motion of Mr. Lai-haw, of Ontario, a committee of one from each judicial district was ai>pointed to prepare and report an address and resolutions for the consideration of the Convention. The President, after some delay, announced the following gentlemen as a committee to select and report permanent olficers for the Convention :? COMMITTEE O.N ORGANIZATION. FIRST DISTRICT. FIFTH DISTRICT. Mark Spencer, John Dean. John H. Bowie. Thomas SHclton. IKOOND OIHTBIOT. SIXTH DISTBIOT. Win. S. Smith, G. H. EUgurton, Donj. Bailey. J. C. Spafford. THIRD DISTRICT. ifVENTH DISTRICT. John J. K ttlo, Vincent Konyon, John T. Hogeboom. O. H Pultn*r. FOCRTII DISTRICT. tlOHTH DISTRICT. Jas. Painter-ton, L. W. Thayer, Noyes P. Gregory. W. R. McAllister. When this committee was appointed, the Convention took a recess until 4 o'clock this afternoon afternoon session. The Convention reassembled at 4 P. M. The collection of sovereigns in the galleries was great er than during the morning hour; the body of the church was also more completely filled. Great numbers of the delegates could not even find standing room. During the recess, the train had arrived from the Ku?t, bringing Benjamin F. B rier, (with the address and resolutions in his pocket,) .Santuel Young, David D. Field, fee. Mr. Young, on entering tne Convention, was loudly cheered The veteran Colonel made an imposing appearance. At 4 P. M., the temporary President called the Convention to order. He observed that it was desirable that the delegates should occupy the body of the ctiurch, and he requested person* sitting in the centre pews who were not delegates, to vacate them. But the sovereigns would not assent to this arrangement. The President said it was impossible for the Convention to proceed unless the delegates were permitted to have seats in the pews.? inere were cries 01 "adjourn 10 me im ?"go out doors," but it could not be done. The President then announced the following gentlemen as a committee to prepare an address uid resolutions for the consideration of the Convention : COMMITTEE Of* ADDRKM Aftl) REIOLVTIONS 1st District.. . .

Benjamin Bailey, of Putnan, from the rommitree appointed to selccj and report permanent officers for the Convention, then made the following report: rnniDEST. lion. SAMUEL YOUNG. Tier. PKEftDENTI, Samuel Waterbury, Abijah Beckwith, Ylexander Watson, Seth Doublcday, John J. Katie, Asa Knowland, John McLane, Samuel Skinner. arraeTARiKs. Gilbert Dean. Stephen Van Dresser, W. W. Scrugham. Peter M. Vosburg. This report wn? unanimously adopted, and the temporary President desired two delegates to eonduct the Mon. Samuel Young to the chair. Mr. Young, on assuming the chair, said : Gentlemen of the Convention:?For this murk of your civility, and .for the unmerited compliment you have paul uie by ielecting roe to discharge the delicate Untie* of this oiflo", when you might have selected to Hv >u; XUIUUIC ntnii./wledgoinent* I will discharge the function* of this oftlce to the bent of my ablity ; for my error* i crave your kind indulgence. I feel proud to be associated with m?-n who are denominated by Southern men a* Barnburner*. Thunder and lightning are occasionally barnburner* (laughter) ; and if thi* Convention will do It* duty, the propagandists of slavery will hear a clap ?f political thunder next autumn which will make them sliaku like Uelshacznr, when he saw the handwriting on the wall. Thi* (speech was received with tremendous cheering. , Mr. jrvett moved thai the democratic (Van Buren) delegates who attended the Baltimore Convention, and who wen kicked out, he now desired to come forward and give an account of their stewardship. Accordingly, Mr. Smith, of Wayne, n member of the Biitimoie delegation, rose and said? Gentlemen of the Convention?You have undoubtedly been aware that the delegate* from New Y'ork who ai tended the Baltimore Convention, have issued an adilren* to the people of this State. That address was widely circulated, and it gave a oorrect and concise history of the treatment and the subsequent course of the delegate* from thi* Ntate. Mr S. Raid he would not now make a detailed report, but he would place upon the (lies of thi* Convention a copy of the report of their proceeding* at Baltimore, together with the credential* which they received from th? Utlea Convention and which were dishonored at Baltimore ^Mr. S. then proceeded to give to the Convention n succinct narrative of the proceedings of the burnburner dejegates at Baltimore. On motion of Mr. Jkwett, the report and credentials were referred to the committee on resolutions. Mr. Pkkston Kino, another member of the Baltimore delegation, was then called out. Mr K. amused the Convention a little while with some humorous allusions to the Baltimore Convention. He used some bitter language in referring to the ignominy and insults which New York had suffered at the hands of tlje Baltimore Convention. Mr. K. concluded hy saving (hot he was with this (Ctiea) Convention, and he had no doubt but it was with him. Martin Grover, of Alleghany, was then called for. This man was lately a member of Congress ; he is one of the most i?'euliar speakers in America; lie speaks inn high treble tone and he occasionally gets oft some humorous remarks. '* ' * w >yyti ^ % ' *"* 11 **' ?,<*V1. ?X?'*g3*^w? W Y 0 !KW YORK. SUNDAY M Ho phI ) he did not want a Southern man proscribed because lie was in favor of e\tending slavery, nor did he want a Northern man proscribed for being o posed to it If the Louth was determined to make a sectional party, we uiust make one; if the South was determined to uiako our Northern uieu a head shorter, let us make reprisals. Mr. G. was very emphatic in his condemnation of the conservatives ; his remarks were remarkably curious, but I have no time to write them out full to-day. When Mr. Grover had concluded his witty and laughable speech, th ?re was a loud call for John Van Buren. He complied with the call, and presented himself before the convention. As I have already remarked he looked extremely well. I mnnot nMrniiif to i/ivp hv\?ii .iii nnflint* nf lim r#? marks to-night. Ilis speech was, however, spirited and pointed ; as a pleader, Mr. Van Buren has tew equals. On rising, he remarked? That he felt some embarrassmeut in coming before this couveutlon. Tbu republicans of this State were left without a candidate for the Presidency. and it hud become the duty of the freemen of the North to nominate a candidate who would have no difficulty in securing the electoral vote of this State There were several indications that the administration was losing ground; and among others was the di-p sition it had eviuced to foster and increase the patrouago of the Executive; another indication was the hostility it had eviuced to the improvement of our rivers and harbors; we hud seen the Baltimore conventions packed by the patronage of tho general government; we had seen them controlled by members of Congress, who wore the mere crea'.ures of the Executive. Vlr. V. B. referred to thn unanimity of Western feeling in favor of the improvement of rivers and harbors by the general government; the popular sentiment was sufficiently palpable upon this subject. But the great question presented to tho people of this day, was whether in going into the territories of Oregon aud California, they would plant there New York or Virginia?a slave State or a free State There nevor was a time wlion the people were so deeply nrousod upon this subject. Prior to 1817. this State was deeply moved upou tho subject of this institution of slavery. Even the great struggle of the revolution never would have i nduced our fathers to eonsent to this disproportionate representation, if they had not believed that the South would consent to the gradual but certain emancipation of ber slaves. Mr Van Buren declared that he had unwavering confidence in the intelligence aud virtue of the people; he was uot afraid to entrust them with the duty of pro tecling their ewn liberties He did not believe tile people of the North would support either Taylorltr Cass He had heard a curious anecdote the other day. At a raising." a vote was recently taken for the nominees for President. A young man asked a comrade, who was present at the raising, what was the result of the vote Ho was informed that it was a tie. "Why," said tho inquirer, "I thought you told me that there wero no Taylor whigs in your town." "Well, there alu't," was the reply; "there is no Taylor whigs nor uo Cass democrats; that's tho reason it was a tie." [Laughter.] Mr. V. B.'s speech was very brief. He recommended the Convention to forget all past controversies and difficulties, and nominate a man who could secure the electoral vote of New York by a triumphant majority. Benjamin F. Butler of New York, followed Mr. Van Buren. The speech of this gentleman was eloquent and impressive; but it was in matter a mere repetition of all the speeches which the barnburners have made since ihey were ejected from It was well known that Mr. Butler had in his possession copies of a correspondence which had recently taken pi ice between Martin Van Buren and the delegates who represent the city of New York in this Convention. When Mr. Butler had sat down, Mr. I-'ield, of New Yorit, announced the fact that such a correspondence had taken place, and in tne name of ths Convention he asked that it he now read. This request was acceded to by Mr. Butler, a d he accordingly proceeded to read the following correspondence: THE DELEGATES TO MARTIN VAN BURKN. Nbw Vohk, Juno 10, 1848. How. Martin Van Burkn, K.t- "rerident .jf the United Statei : Sir?The undersigned delegates, appointed by sovoral of trie Assembly districts of tho city and county of New York, to represent such districts in the Democratic State Convention. to be held at Utica on the 22d instant, complyiug with their own feelings, and with those of their constituents, find It necessary to address you on a question of great moment, which may be expected to come before the proposedCouvention. Thisas mnbly as you are aware, has been convoked in conse I iueuee of the arbitrary and insulting exclusion by tb. .National Convention lately held at Baltimore, of the delegates regularly appointed torepreseut the democracy f this State in that Convention, from any effectual rote or voice iu its deliberations, for the purpose of , ixprossing the sentiments of their constituents in re! ,'ord to that measure, and of recoinin-iuding. should they think fit so to do. candidates for the offices of President and Vice President. If t' e l mivention shall decide to make such nominations ur . wn eyes, aud we believe, those of the whole hwdy. 'm l instinctively be turned to you as the de mocratic statesman best qualified by taleut and experience. as well as by purity and the soundness of your political p 'inciples. to receive the first of tbe.r nominations. The gre it Jeffersonian doctrine?now boldly re }juui*mu in hi" aiiui.ii, nuu uy n?u iiihu^ tmui'ijr hurruulered in the North : that slavery, or involuutary servitude. should not. by any action of the federal government, be entered into the territories of this Union? deserves, in connection with the other and tune-proved doctrines of the democratic party, to be represented by a standard bearer of the highest eminence for ability and worih ; and such an one. you will permit us to say. we shall present in you. should we be authorized to name you as a candidate for the consideration of tile convention. We are not insensible to thb many reasons which may properly induce you to forbid any such use ot your name. Having tilled with highest honor, the first station in the republic, and being now retired from the political arena, you may be unwilling to be drawn from the quiet and useful pursuits which occupy your attention, for the purpose of being involved in the strifes ot parly. We remember that in your noble letter to th< democracy of this'ity in June. 1814. in whiek you gave to Messrs. Polk ahd Dallas so cordial and so generous a support?a support, which so greatly contributed to heir election?you declared in reference to their nomination and to the po-it ou in which it had placed you. that your political career had forever closed. We know that you have neither done anything yourself. nor countenanced anything in others, to vary this position, and that you lately refused to the delegates of this State, In the event of their reception by the Bab timore Convention, permission to use your uame as a candidate before that body under these circumstances ; and, unwilling to embarrass one who has always, whilst in the political field, stood ready to place him -elf at ttto ilispo al of his friends, we do not feel ourselves at liberty to insist upon a compliance with our wishes to the extent iliat we might, under other circumstances, have been induced to do. We are. moreover, sure that you will naiuraliy weigh tha many aud grave considerations which belong to tile subject, and decide it in a spirit of liberality to your friends and justice to yourself. Should you feci yourself required to adhere to your previously expressed determination not again to be made a candidate, wo earnestly hope you will not withhold from ns your opinions in regard to the action of the Baltimore Convention, the obligations, whether of duty or expediency, resting on the democracy of New 1'ork towards the nominations made by that body, and the course proper in the present crisis to be pur?ued by the democracy of New York, as to the great issue before the country, the extension ofslaveiy to territories now free.

It tuade Impressions upon my heart which are as vivid now as they were then, and which will never lose their hold upon iny affections until that heart ceases to beat. It is not In my nature to decline a compliance with any request which such men are capable of making, except for reasons of the stronge-t character, and which they themselves will, on further consideration, approve The determination announced in 1844, in my letter to the New York committee, advising my friends to unite in the support of Mr. Polk. to regard my public life an forever cloned. wnn made upon the mont mature reflection, and with an Inflexible determination to adhere to tt to the end. I heg of you to do me the juntice to believe. that It wan In no degree Influenred by that nplrit of renentment which political dlnappointinan'n are no apt to engender in the be?t regulated mlnda.

But whilst thus in good faith discharging what I regarded to be my duty, it did not fail to occur to me that the circumstances by wbich 1 was surrounded, presented the occasion I had loug desired, wheu i could ret re from public life, uousistently with what was due to the couutry, to my friends, and to my own self-respect. 1 embraced it with my whole heart From that day to the present, my mind has not for a moment wavered in regard to the determination then aim >unced At an early period iu the present canvass, and before the dem >cruti mind could be regarded as having taken anything like a distinct direction in reference to its candidate I reaffirmed my resolution iu this regard Iu a letter to a worthy citizen of Pennsylvania, which has been extensively published, and iu uiany others with which it was not d-?iued necessary to trouble the public. A frloudly application from our delegates to ihc last natioual convention, for authority to use my name as a candidate If they could do so under proper circumstauoes. made it as you appear to be

Inf irmed. my unpleasant duty to refuse my consent to their doing so under any circumstances whatever. Having thus assumed aud so long occupied this position, I trust to your friendship and pa-t indulgence to be excused for repeating my unchangeable determination never agaiu to be a cauddnle for public office. The f?ct of my haviug loug since retired from public Ill*, with trie tacit approbation of my friends, gives me a right to say no. If whilst in the political field will, ing to reoelve honor and advancement at.the hands of my political friends, I did not show myself at all times ready to obey, without regard to personal consequeuces. their calls to pngt* of difficulty, I failed to make myself understood by thoSb whom I was most anxious to serve. The considerations to which I have adverted, are not entitled to the same controlling influence in regard to the remaining subject of your letter Whatever would be my preference in such matters on ordinary occasions, I feel that I could not. under existiug circumstances, refuse to comply with' your request, without doing inustice to my democratic friends in this State. I shall, therefore, give you my unreserved opinions upon the questions to which you have called my attentlou ; and in doing so I shall endeavor to observe that respect and courtesy towards the conflicting views of others, which it has always been my desire to practice, and which is now more than over appropriate to my position To give the doings of a Democratic National Convention a claim upon tho support of the democracy of any State, it is indispensably necessary that the democracy of that State should be fairly represented in such Convention, and allowed eqUHl rights and privileges with their political brethren from other States in regulating its proceedings. Neither of these, although perseveringly demanded, was conceded by the recent Convention to the democracy of New Vork. and they arc of course in no degree concluded by its decisions. Out although their rights and their duties are thus clear, it is notwithstanding material to the fraternal relations which have her?tof ire existed between them and those who composed the Coaveution, that it should be distinctly shown at whoso door lies tho wrong of their exclusion ; whether at that of our own delegation, or of the Convention. Upon this point both sets of delegates claiming to represent New Vork, although differing iu almost everything else, appear to have concurred In the opinion, that the action of the Convention had been sur.h as to put it out ot their pow r to participate in its proceed!ug.i, without a total disregard of what was due as well to their own honor as to the honor and just rights of their State. It was therofore but reasonable to expect that here, at least, tho op>niou against the slightest obligation on the part ot the democracy of New Vork to sustain the doiugs of the convention, would be universal. To And either set of tbe delegates who claimed to represent New Vork lu that convention, or their friends who approved of their conduct, casting reproach upon their opponeuts for not sustaining the decisions of a body, of whose action in rogard to their own Btato, they )iu 1 vnspeotivoly formed ? nd expressed the opinion to which I have adverted. must, it seems to ino, bo regarded as a very extraordinary ucourrenee in politics. It was plainly the duty of the Committee on Credentials to examine into tho facte, and report their opinion upon the conflicting claims referred to them It is an indisputable fact, that instead of doiug so, they required an unqualified pledge front both sets of dulegutes from New l'ork, that they would support the nominee of the convention, whoever he might be. and resolved that without a compliance with this arbitrary ex tction, they would not even look into the merits of their respective claims. Now when it is considered that no such pledge was required at any previous National Democratic Convention from any person?that at one of them the dolegatea from an entire State (Virginia) were permitted to announce their deteruiination in advance not to -upport a certain nomination, if it should be made without causing a question to be ra sed in regard to their seats in the oouvention. and that they carried sueb refusal into full effect, without subjecting them s-lves or their Stai e to the reproaches of Uiolr awocales in other States?that this very convention conta ned, without dispute as to their eligibility, delegates from several States who could not enter into such pledge, without violating tho instructions of their constituents. and whose intentions not to enter into it. were not concealed ?that the convention itself had previously and expressly refused to impose such a pledge upou its members, and that ou the very committee, which so imperiously demanded it from the New York deleL'a'es, there were members who openly denounced its exaction as an outrage -declared their utter unwillingness to take it themselves, aud who also, were nevertheless recognized as eligible and fit members of the convention?when these things are considered. is it possible that any right-minded citizen among us can fail to regard this treatment of the New York delegates, as an indignity to them, and to their State, of iho rankest character? if it is our misfortune to live in a community with whom it is necessary to resort to argument to prove this, whose iniuds do not rush to that conclusion at the mere pre-entation of the subject, It is of very little importance lo us what is said or done in a iieinocratic convent on umers may ttnuk differently. and I bare neither the right nor the disposition to become their accusers but speaking for my.-elf, and for myself only, I do not nealiato to say that the representative* of the radical democracy of this State, were entirely right in their appreciation of the treatment they received and in the course they adopted.

The matter wan nevertheless so disposed of Now York was allowed a dmiblo repro cntation with the inevitable and weil understood consequence, that she should not have a single effective vote upon the proceedings of a convention whose decisions she Is now called upon to sustain. Your delegates claimed the exclusive right to represent the democracy of this State in the convention, and offered , to maintain th-lr title theieto beforo that body by documentary proof. Their claim was reje-ted and on what ground ?

They were also too upright, ami the fraternal feelings which had carried them through the struggle lor independence were too strong, to permit them to deal with such a matter upon any other principles than those of liberality and justice The policy they adopted, was, to guarantee to the States in which slavery existed, an exclusive control over the subject within the r respective jurisdictions, but to prevent by united efforts, its extension to territories of the United States -in which it did not in fact exist On all sides the most expedient means to carry out this policy were adopted with alacrity and good feeling Their lir-t step was to interdict the introduction of slavery Into the Northwestern Territory, now covered by the States of Ohio.

Virginia made tho cession of tlie territory upon which the ordinance wan intended to operate, and the representatives from all the slaveholding States give it a unanimous support. Doubts having arisen In the minds of some whether the ordinance of 1787 was authorized by the articles of Confederation, a bill was introduced in the new Con- | gress at its first sessi n under the constitution, recog- [ nizing and adapting it to the new organization, and it ; has ever since been treated and regarded as a valid act This bill received the constitutional approbation 1 of President Washington, whose highest and sworn ! duty it was to support tho constitution under which it was enacted Nor was the north backward in doing its part to sustain the policy which had beeu so wisely adopted. They assonted to the insertion of provisions in the constitution uece-sary and sufficient to protect that interest in the States, and they did more. The trouble apprehended at the commencement of the government from this source, began to show itself as early as the year 1700. iu the form of petitions presented to Congress, upon tho subject of slavery aud tho slave trade, by the Quakers, of Philadelphia and New York, and by Dr. Kranklin. as Prestdeut of a So- , ciety for the promotion of abolition. Those petitions i were, in the House of Representatives, referred to a j committee of seven, all but one of whom were northern members, whose report, as amended in oomraittec 1 of the whole, affirmed " that Congress have no power to interfere in the emancipation of slaves, or in the treatment of them within any of the States, it remaining with tho several States alone to provide any regulation therein which humanity aud true policy might require The perseverance and good faith with which both hrauches of the policy thus adopted have, until very recently, been recognised and carried out. are highly honorable to the whole country Tho peculiar liabi lty of tho subject to ho convorted into an element of political agitation, as well in the slareholding as in tb? non-slavoholding States, may have led to occasional attempts so to employ it. but these efforts hare been very successfully frustrated by the good sense and good foeling of the people in every quarter of tho Union. A detailed account of tho numerous acts of the federal government, sustaining and carrying into full effect the policy of its founders upon the subject ot slavery in tho States, and its extension to the territories. and the stens taken, in the nnti-slavohnWIInis I States, to suppress or neutralize undue agitation in regard to it, would bo alike instructive and honorablo to the actors in them. But it will b? readily perceived, that this could not bo given within tlic necessary limits of a communication like the present, it must therefore suffice to say. that, from 1787. the date of the ordinance for the prevention of Hlavery in the north western territory, down to aud including 1838. at least elevou nets of Congress have been passed, organizing territorios which trive since become States, in ad of which the constitution^ power of Congress to interdict the introduction of slavery Into the territories of tho United States, is either directly exercised, or clearly asserted by enactments, which, as matters of uuthorlty. are tantamount to its cxeruiso ; and that at the only p?riod when the peace of the slaveliolding States was supposed to be seriously endangered by abolitiou agitation. there was a spontaneous uprising ot the people of the North, of both parties, by which agitation was paralysed, aud the South re-assured of our fidelity to the compromises of the constituiion. In tho laws for the organization of the territories which now constitute the Status of Ohio. Indiana. Michigan. Illinois. Wisconsin, and luwa. slavery was expressly prohibited. The laws for the organization ot the territories of Mississippi, Orleans, Arkansas, Alabama and Klorida. contained enactments fully c<iuivuieut in regard to the extent of power in CoDgress over the subject of slavery iu the territories to the express exercise of it in the other a-es These acts were approved by Presidents Washington, the eider Adams. Jefferson. Madison, Monroe, Jackson aud myself all bound by our oatlis < f office to withhold our respective approvals from laws which wo believedSmuolistltut onal If in the passage of these l.tws during the peri id of half a century, and under the adininis- ration of so inauy Presidents, there was anything like sectional divisions, or a greater or less participation in th?ir enactment on the part of the representatives of the -bin-holding, or of the non-slaveholding States. I aui riot apprised of it I believe the plan devised by the founders of the government, including the fathers of our political church, for the treatment of this great subject, and which lias hitherto been so faithfully sustained. and which has proven so successful in preserving the union of these States, to be not only the wisest which the wit of uian could have devised, but the only one consistent with the safely and pro mrrilv of the whole country. 1 <1? therefore desire to see it continued ho long as slavery exists in the United States. The extent to which I have sustained it in the various public stations 1 have occupied is known to the country I was nt the time well aware tiiat I went further iu this respecUthan many of my best friends could appro^e.? But deeply penetrated by the conviction that slavery was the only subject that could endanger our blessed Union. I was determined that no elfort ou tny part. with<n the pale of the Constitution, should he wanting to sustain its compromises as they wore then under stood, and it is now a source of cousolation to me that I pursued the course I then adopted. The doctrine which the late Baltimore Convention has presented fur the sanction of the nation, is, in substance, that the laws I have referred to were hut so many violations of the constitution?that this instru munt confers no power on Congress to exclude slavery from the territories, as has so often been done with the assent of aii. This doctrino is set forth in the pub iished opinion of the highly respectable nominee of that convention, who it is well kuown received that distinction because he avowed that opinion, and who it is equally certain would uot have received it. if lie had not done so. It is proposed to give this doctrine the most solemn sanction known to our political system. by the elrcliou of its declared advocate and supporter to the Presidency. If It receives the proposed sanction of the people of the United States, the result cannot he doubtful The policy in regard to the extension of slavery to the territories of the United States, into which it has not yet been introduced, which has existed since the comuinnccinont of the government, aud the oonsequences of which have been so salutary, must cease, and every act of Congress designed to carry it into effect be defeated by the veto of the Executive. The territories now owned by the United States, and very acquisition of territory that may hereafter be made by the I'nited States, whether obtained by annexation. by cession for a valuable consideration, or by conquest, must, as long as this opinion is held, and as far us the action of the national legislature is concerned. be subject to the inroads of slavery. And this consequence is to be submitted to, on the asuinptinn that the framers of the constitution, with their attention directed to the subject, and with a well understood desire to do so. have failed to clothe ( tsngress with the necessary powers to prevent it. I cannot, by my vote. I contribute to this sanction. I cannot do so. because i I cannot concur in the opinion which wc aro called upon 1 to sustain Kntertalnlng these views of the constitution.

In fact, and from the residus of which it has been expressly abolished by the existing government. We are called upon to do this at a period when the minds of nearly all mankind have been penetrated by a conviction of the evils of slavery, and are united in efforts for its suppression ? at a moment, too. when the spirit of feeedom and rw* form is everywhere fir more prevalent than It has evar been, and when our republic stands proudly forth as the great exemplar of the world in the science of free government. Who can believe that a population like that which inhabits the non-slaveholding States, probably amount, log to twelve millions, who, by their own acts, or by the foresight of others, have been exempted from the evils of slavery, can. at such a moment, he induced, by considerations of any description, to make a retrograde movement of a character so extraerdinary and so painful ?

This semi-National Convention is much more imposing in its appearance than I had believed it would be. The people seem to feel a deep interest in its proceedings. My last note guve a , running account of the operations on the first day, down-to the hour of adjournment. The Convention met in the Methodist Church, this morning, at 8 o'clock. liven at that early hour the building was filled, from the dome downwards, with by sovereigns. The Convention wns called toorder, by the Hon. SamU*L Yoitnu, at precisely 8 o'clock. The President said three important telegraphic despatches had just been received, and they would now be read to the Convention. The first, from Pittsburgh, Pa., announced that a letter from the democrats of that city, addressed to the Utica Convention, was now lying in the |w>st office at Utica. The second despatch was from Chicago, Illinois, and it unHouueed that the democrats of Northern Illinois were ready to fraternize with the free democracy of New York. (Vociferous cheering.) It spoke in ftvor of free territory, and suggested a National Mass Convention. It was signed by the MaV'or of Chicago, and one hundred others. The third despatch was from Lafayette, Indiana, which says:?"Our eyes are on you. Indiana will throw a large vote in favor of free territory. W nigs and democrats have spoken in loud terms at the Tippecanoe mass meeting." At iliis point the letter from Pittsburgh, mentioned by the telegraphic despatch, was procured from tin- post-office, and read to tne Convention, as follows; PiTTJBmr.ii, June 19, 1848. Sir?The opponents of the extension of the area of slavery. in thin section of country, look with anxiety at the meeting of the body over which you, preside. They feel that a very pregnant crisis in the history of our country, and the causo of humanity, has arrived, and that the results of that oriels, whether good or evil, mui-t depend greatly upon the course of action of the body over whioh you are the presiding officer. They believe that a tirin perseverance in the resUtauco which you have commenced against the shameful irucUlina to the slaveholding power, even if eonlined to your own State, will exercise a powerful and henelloinl influence throughout the Free Statee; but they also believe that you may, by wise and judioioua 1 action, greatly extend the scope of that influence. I There it great and general dissatisfaction at the pre- 1 scut nnsition of t.ho old nnlltie?i necessary to afford a rallyiug point for this general discontent. to secure to it a power which must appal all those truckling demagogues who hare howi-d before the dark spirit of slavery. Time for decision is now short ; the day of election ia rapidly approaching; corruption la daily exercising ita reducing arts, and those arts will of course be inorc potential while the elements of opposition are deatitute of form, union and definite purpoae; while the free and honest spirits of the land are daily und hourly driven to exclaim " Where shall we go." The arts and arguments ot the serviles must of course he most potent and seductive. We therefore take the liberty of suggesting to your Convention the policy and propriety of calling a convention of all those opposed to the extension of slavery, at Cleveland. Ohio, sometime in July. We believe that such a convention would be largely attended. and surely from no place could a protect against H the slave influence come with morn propriety than H Prom that great State the first and healthful offspring H of the glorious ordinance of 1TS7 Let It he known H that surli a convention is to assemble, and the oppoeC H lion to the slave rule will no longer be at sea without H chart or compass, liable to be misled by every baneful H influence.
