Bro. Treadwell's letter, which we publish in another column, contains statements rÃ©spectirig thÃ¶ Chicago Convention grossly erroneous, altliough thcir falsity doubtlÃ©ss escapÃ¨d his riotice. He says that the Convention "determined by a strong vote ngainst the expediency of multiplying new and dangerous tests of membership in the Liberty party." It is not truc that any "nexo tests" of any kind were proposcd for adoption ; and consequently it is not true that the Convention voted against, "muUiplyingV such "new tests." The resolution for supporting the equal rights of a men, which wc published last week, and wh'ich was here voted down, wasidopted, word for word in May, 1840, by the first National Liberty Conventionr, by a unantmous vote. How then could that be a "nao test" which has been the unquestioned faithof the wholc party for six years, and which wiH remain so till rescindcd by another National Convention? The "dangcr" of tliis test was not discovercd till it was brought to lig-ht by speakers at the Chicago Convention ; and even therc not a single speaker would takc ground against the correctness of the resolution itsolf, but the Convention voted it down becau? e it was deented e.pcdiept for t'io Liberty party, while laboring in defence of the Black man's rights, to maintain a general silence in rcferenco to the rights and intcrests of the White Man.(tAs the New York Tribuno has been extensively rirculated in this State, mul hos been well known for its parti.an 7.erl and bittenie.s., for its talent nnd vigor, and for iis manifest and .striking nconsifctencies of various kinds, the iullowing recent announcmenl of its present position niay be of interest to our readers.

Every village where a Telegraph station is kept wil! have a bulletin to announce the news daily or twice a day; and millions will bediscussing the same topics in every part of the Union at ilic same moment.

Monterey, the place wherc Gen.

He did not complain of tliis as extrav. agant or unnecessary, but it would be burdensome to the people, and must tesuli in a National Debt, or heavy Taxation. His advice was to propose torms of peace. Mexico was the weaker party: she wns unsupported by any other power: and proposals of peace might be hononibly made on our part.
