Mr. Seward to Mr. Adams .

No 46.]

Sir: My despatch, No. 42, dated July 21, was delayed beyond the proper mail day by circumstances entirely beyond my control. I trust, however, that it will still be in time.

Our army of the Potomac on Sunday last met a reverse equally severe and unexpected. For a day or two the panic which had produced the result was followed by a panic that seemed to threaten to demoralize the country. But that evil has ceased already. The result is already seen in a vigorous reconstruction upon a scale of greater magnitude and increased enthusiasm.

It is not likely that anything will now be done here, hastily or inconsiderately, affecting our foreign relations.

I am, sir, respectfully, your obedient servant,

WILLIAM H. SEWARD.

Charles Francis Adams, Esq., &c., &c., &c.
