Mr. Adams to Mr. Seward.

No. 667.]

Sir: In relation to the suggestion made in your despatch No. 893, of the 4th of April, I have already anticipated it in a note addressed to Lord Russell on the 16th instant, based on the depositions of twenty-one persons enlisted by the rebel agents, furnished to me by Mr. Morse. These papers are so voluminous that copies will not be ready for this week’s steamer. They will be sent next week, in company with my note.

I have the honor to be, sir, your obedient servant,

CHARLES FRANCIS ADAMS.

Hon. William H. Seward, &c., &c., &c.
