The Proslavery Washington Paper

A letter writer at Washington sn)fs: "It has been supposed that the Charleston scheme for the establishment of a newspnper, devoted to the intercsis of slaveholders, and intended fur the defence of the peculiar instilutions of the South, would be carried iuto eflcct before the close of this year.

He will not therefore be selected. As he is connected with Mr. C'alhoun's familv, by the interinarriage of a daughler wiiíi Mr. Calhoun's son, it may be presumed that he was supported in his pretensions by the southern Senator. Whether tho defeat of the efibrts of Mr. Green, will have any influence in chilling the i;rdor of the promotersof the scheme, 1 am not able to say."
