The Worcester Convention--mr. Van Buren

Boston, June 29, 1848. To the Edito of the National Era : The Free Soil Convention at Worcester, six thousand strong, adjourned at ten o'clock last night, It luis been h memorable ocettainn. The dissolution of tlio oíd parties lias boen effeetually pronounced. A rnoveinent has been commenced ir tlie country town of .Massac'msetts, i'rom the sneer impulse of tlit peoplu, which promises, like tbal m Obio, lomergenll old distinctions in the one issue of the non extensión of' slavery. This movement is but a few days, hardly u eeks old, and yet. as the probable seed uí a revolution, ihould bommaiid attention. ou will receive the detüils oí this Convention f'rom otliers. I wish only io make a few remarks on its tone, and some of its special events. The majority of the Convention bslougcd to the late Whig party. Old recoilections and associations would therefere oecasionall v come up; bul the whole enthusiasm of the meeting was reserved tbr the declaration, freqUenCh repeated, that every issue and name should be merged in the one object nf oppositien to slavery-extension. There was no pardal conse cration of the heart to the new movement. It wus (horough and unreserved. Jt was generally taken for granted that the issue in the present contest was to bethe nonextensión of slavery ; but the feeling of thu meeting, indicated by the responses to the speakers, went (ar bsyond this, embrar.ing th whole scope of the Liberty movement. The new oiganization in Massachusetts understands and accepts the whole work before it It is ready and anxious for the struggle. Very clear and unmistakeable indicatiuns were given of the preference of the Convention for the individuals who should represent them in the national nominations. The names of Hale and Giddings, coming up in various connnections, were received wilh unbounded enthusiasm. An allusion to ' John and Josh - ua""met wnh the heartiest applaus e, and finally, when the Rev. J. P. Lovejoy, in tlie evoning, of these two men as the candidates on which all could unite, the cheering was deafening and prolonged. Mr. Van Buren received also the commendation of the Convention for the positive ground taken by him, but not in any connection as its candidate. As regards Mr. Webster, the cry carne, " It is too late," and the Convention could not even be induced unanimously to express the hope that he would stand forth as a Northern man, although his refusal, as yet, to endorse tl:e nomuialion of Taylor, met wilfa warm approbation. The letter of Mr. Van Buren was a subject of conversalion among the members, and alluded to by one of the speakers. This letter is, so lar, the most marked event of the present campaign, and, expressing In-re the opinión of a single individual, the most dangerous event wliich has occurred. lts first idea is, the Democratie purly ; its second, Free Soil; and this last so assoeiated with compromise toward tlie South, as to form a basis, and the only possi ble basis, for a National Democratie Party liereafter. The object of the letter seems to be, to d-'fine the present movement and limit it, to place veto-pledges and barriers in front ol it. Now, it may not be poss'ble to control the movement once commenced, but the whole tendency of the letter is to offer a ground of concession to the -South, affirming the position held by them in the National Government, before their recent agyressions. One singlo fact, in conclusión, should be brought out wilh regard to this ConventioH. lts enthusiasm was unmeasured, bordering at tunes, even on wildness. No sucii demonstration has taken place in Massachusetts snee 1840. The life exhihited ljy it contrasts, in a striking manner, with the"omnious silenco of tht ratification meetings of the paities.
