GoviTnor Prker is expocted to announce his ftooeptance of the noinination by a gpeeou a a ratification meeting to be held in New York, and J.udgfe Davia has written a lotter to the chai rman of the convention thanking it for tho " uuexpected honor ' oonferrea upon hini, and stating that "Uu Chiftf Magistraoy of this Républic shouli neitherbe sought nor declinacTby an Am erican citizen. ' The indications are tha 'the Labor Keformers are in eaniest, an that they mean business. David Davis whoin they have selected as thoir staivd ard-bearer, was born in Cecil County td., on March 9, 1S1Ó. He-graduated a Kenyon Collego, Ojío, in 1832, and subsequently studied law in Massachusetts and also at the Law School in New Ha ven, Connecticut. Reraoving to Illinois in 1835, he -was adinitted to tho bar, ant soon after settled at Bloomington in tlu practico of his profession.

Ii 1855, and again in 1801, he was re-electea to this position. He had long been an intimate personal friend of Mr. Lincoln and as a delégate to the Chicago Convention of 1860 had a largo share in securing his Bomination for the Prcsidoncy.
