Read it through once

No man who will consent to go south, and perform this dirty work, is capable of writing truth. And moreover, many of the letters published in abolition papers, purporting to have been written from some part of the South, were concocted by editors and others at home; the writers never having traveled fifty miles from their native villages. But some of them do travel South and write letters; and it is of but little consequence what they see, or what they hear; they have engaged to write letters, and letters they must write: letters too, of a certain character; and if they fail to find material in the South, it then devolves on them to manufacture it.
