Washington cor respon il ence N. Y. World. "Wasiiixoton, Maroh 17. - Tho tediuni of tho fcniturday scssions of tho House was relieved yestcrday by a very fair attendance and by a vary vigoroua and ablo dubate on the tarift'. Mr. Kerr, one of the Democratie ïueinbers of the Ways and Means Coinniittee, opeued tlie discussion by one of tho clcarest and most forciblo efforts on this great question ; a question, too, which is veiy generally sought to bo illustrated by elaboratoly involved theorios instead of by facts and figures. The speech grated harshly on tho ears of tho protective tariff interest, and Mr. Kclley, of Pennsylvania, deuiuring that none such should go the country without an answer, proceoded to inake a vehemont reply. Mr. Kerv oponed his remarks by defining what constituted a tariff fbr revenne in our existing syetcras oL taxation, and then pioceeded to giv& forcible examplcs ;nil illustrations of revenuo duties, as citod iu tho case of salt, coal, coffce, woolens, toa, sugar, silks, spirits, wines, tobáceo, &c , in which he inultipliod oxamplos of a vicious tariff adjustlaent. He followed this by an exposition of the truo principios of tariff reform, demonstratcd tho actual cost of governmont to eiich citizen, exploded the delusire cry about the pauper labor of Eu ropo, illustrated what American industry necded, and concludod by showing that the pretentious demands of tho protectionists entirely ignorud tho oijual rights of all othor classes, especially agriculture ik1 other unproteotodpursuits. Hopaid his raspects to the freo toa and coffeo delusiou ip this wisc. Speaking of the du ty on eoffoe he said : " Bnt tlie iraportation of coffce during the calendar year 1871 was 321,086,707 pounds, equal to eight and a quarter pouuds for each person in the country. Tho tot:il importation is cstirrettcd at (3y,7'2J,O17 in gold, and the duty por pound is 'i cents, boing loss than 30 pur Cent. nii viiloieui ; and it paid to the Trcasury (9,830,601, It therefore cost the conklitners por capita u. trifle less than 25 cents, and did notcompol them to pay a ycuuy t ) monopoly, ft is a rovenue tax, jiure aml siraplo, costs the peoplo what it pa,ys tUe govtruraoat, builas up no stupendous fortune at tho expenso of tbo peoplo, fostors no corrupt corporation or rings, and bars the door against uo competition.
