Methought I wuz in Philadelphia, and the 14th uv August had arriv. There wuz a glorious assemblage, ez Doolittle sed, uv the brains and hearts uv the country, and I may add, ez I and Humphrey Marshall wuz there, uv the bowels likewise. The Convenshun wuz assemblin. There wuz Seward present, engineerin uv it. On one side uv him I notist, in my dream, a shadowy bein with wings, draped in white, and wearin a melonkoly look, with one hand a layin on his shoulder, a tryin to take him out uv the hall, while another bein, with wings like a bat, hed him by the nose, and wuz a twistin uv him jest ez he desired. I notist that this last mentioned bein hed hoofs, wich wuz split, and a tail wich he wuz flirtin in great glee. The bein with the tail and hoofs whispered suthin in Seward's ear, whereupon he moved that that eminent patriot, Ex-President FRANKLIN PIERCE, be chairman; upon wich the shadowy bein in white unfolded her wings, and flew away, castin at William the most sorrowful look I ever saw, the hoofed and tailed individooal laughin tremendous. The Ex-President took the chair, and one Vice-President wuz appointed from each State, ceptin Vermont and Massachoosits. My buzzum swelled with emoshen ez that list wuz read; it wuz more like an old-fashioned Democratic Convenshun than anything I hed heard for five long years. I heard the honored names uv Toombs and Rhett, Pryor and Lee, Slidell and Rosso, and Dandridge and Forrest; I heard the names uv Craven and Pollard, Thompson and Forsyth, and I felt like him uv old--"Mine eyes hev seen thy glory, now let thy servant depart in peace." Nothin but the certainty that I wood at last hev that Post Offis at the Corners kept me from goin up. Singler 'tis wat slender ties hold us to earth! The Secretaries wuz apinted, and then the committees--two on each from the South and one from the North, wich wuz consiliatin. I wuz put on the committee on credenshals, Randall, the Postmaster-General, bein the Northern representative. We hed our hands full. There wuz a rush made on us, so many claimin seats that we locked the doors for two hours to decide what shood be the proper qualification for a place. Finally we agreed to admit ez delegates,-- FROM THE NORTH--all Dimocrats who had bin arrested by Linkin's minyuns; all officers who hed resined rather than to serve in a Ablishun war, and all Republikins who cood show a commishun ez Postmaster and sich, and (this wuz considered necessary to guard agin imposition) who wuz willin to take his solemn oath that he wuz a steadfast bleever in everything A. Johnson hed did sence Janooary, '66 (ceptin sum small items wich wuz specified), and all he wuz doin, and all he mite do. FROM THE SOUTH--all who cood show a officer's commission in the late Confedrit army; all who had receeved a pardon from A. Johnson, and all who hed lost their niggers in an unholy war, wich inclooded all present.
