She came through our lines on a Government pass as I am informed and is to return to Richmond soon. She is open - mouthed an shameless (even to the disgust of her own family) in proclaiming secession doctrines. But the matter of importance is this: She has, so she says, purchased over $ 2,000 worth of goods in New York to take back with her, and probably will bear dispatches to the South from Northern traitors.

Yours, truly,

A. W. CLARK, M. C

I knew that such would be the effect, and you may recollect my so stating to you when I last saw you. I am now awaiting the arrival of the prisoners from Fort Delaware to proceed to City Point and meet Mr. Ould. In addition to the exchanges of officers I have to arrange those to the numerous deliveries of enlisted men. I have no doubt that in the coming settlement Mr. Ould will present heavy accounts of paroles
