Il is well kriow to Ã¶ur readers, that tho Slaveholdcrs generally Vvere very lmstile lo the nevv postngc law. E vcry Slaveholder in tho llou-e voled agninst it. - The slavoholding PoÃ¡tnaasler General Cave Johnson of Tennessee, recommendÃ©d Is rep.Ã©al; and we see tliat in tho House a bilÃ has boen reponed to Ulerease very largely the present ratcs. It provides that lor every letter or packet of one quartcr of an ounce or le.ss, convevcd 300 miles or leas, 5 cenÃ?, over 300 and less tlian G00 miles, 10 cents; over 600 miles, 15 cents; and for. every additional ppstage, e.xcepi wheri a letler is w ritten on a single sheet of paper weighing over one quarter of an Ã¶unce, or IÃ«ssthari one halfan ouhee, the single postage is to bc charged; the ratos of 15 cents to discontinuad from and afler the lst of July, 1818, if in the opiniÃ³n of the Po.st Mester General, the revenuesof the Department equÃ¡l its ex pendil u res, and in that case 10 ccnls shall he charged for all distances over 300 miles. The second section, relating to newspnpers, provides that papers sent by publishers, to subscribers or ngents, less than 100 miles, 1 cent; over 100 miles, 2 cents; pamphlel. &c. per sheet, less Jhan 100 miie?, 1 cent; over 100 miles, 2 cents. We are inclined to thiiik thal this bil!, asdistastcful as it may bc to the Cree state?, if it be urged wÃ¼h diligence, will pass: for when did the Slaveholciers ever sel themseles in earnesl to eÃlVct a politica] object without acoonripliahing iÃ¼ The present law i.s very generally liked at the NÃ³'rth: it has not yet had any thing like a fair trial: and yet the amount of Posta ge is steadily on tho inercase.
