Correspondence Of The Tribune

Washington, Monday, July S. The best abolition speech made n Cotigress t'iis sessior was deliyered yesterday, ti the Senate by Mr. Johnson, of' Georgia. It is but fair, however, to acknowledge that he had uot ufficient astuteness to discover the purport and inevitable tendency of his speech, unless he was socretly desirou.s to giye to " the question ol'thoago" more vilality than its professed adTocates are abie to furnish it with. He contended th;it every acquisition of'territory by the United States, whcther by convuest or cession, must c.r neessüaü rei be aclompanied by the extensión of slavery. IC Canada should be ceded to us by iho British Crown, slavery ipso facto wotild be extended ovor it. This was liis doctrine, so far ns it was intel'!e. Mr. Cali, aun, who seldom suffers himseil'to 10 taken by snrpi ise, seoined somewhat , puzzled, and more than nsiiai copitative. In the course of his remarks, iJr. Johnson iilliidod to Mr. Halo as the Representative of tlie District of Columbia. In a brief rcply, Mr. Hale said that he held his spat by the election of the LcgUlature of New Hampsliire. Il was as good a title as uiy Senator conld chiün. - And he would teil the Senator from Georgia, lliat he represented a Stato of Freemen : " no s'ave breathcl its air; no eneoiy ever impressed his footstopü apon its lóil." Everyiody uknowleages, even those most axklicted to the interests of slavery, that Mr. Hale boldly raaintains his exposod posilion in the Senate. Mr IlaK; forbore, (rom a feeling of magnaiiiniity, to nlludo to Mr. Johuson'a pesition - the nicre tocum tcnens of Win. C. Dawson, a temporary ttp pointee of tlio Govornor, nguinst the pi,lticil opinión ot'the Legisluture.
