Unwilling witness caught.
--Detective officer J. Washingon and week, after a long search, in apprehending a female called Charlotte Coleman, a cyprian, and late a resident of this city, who was not long since bound ofter to appear as a witness against certain parties charged with counterfeiting Confederate Treasury notes, and who, on the day not apart for the trial, turned up missing. The agent of the Government, deeming that the witness had been tampered with, set his wife to work to trace out her stopping place, and, after a long search, lit upon her in. Memphis. Combined with the address and skill necessary in so important an operation, there was a degree of assiduity displayed by officer Goodrick that may well merit commendation. The trial of the party against whom Charlotte Gilman was a principal witness, was postponed until the 8th a April,in the rather vain hope, as it seemed at the time, of securing her attendance.--Owing, however, to human ingenuity and perseverance, she is on hand, and likely to further the ends of justice.
