Mr. Seward to Lord Lyons.

My Lord: I duly received and have taken into consideration your note of the 23d ultimo, relative to the case of Mr. John J. Shaver. Notwithstanding the remarks in that communication, this government; is of the opinion that, under the circumstances and at that time, there was probable and justifiable cause for the arrest and temporary imprisonment of that individual. Whether he could have been convicted of treason upon the proof which has been referred to in the correspondence between this department and her” Majesty’s legation, is a question which it is now too late to determine, as he was released without formal trial. In the event, however, of a joint commission for the purpose of adjusting claims, his case, both upon the facts and the law, may be judicially examined and decided to the mutual satisfaction of all parties.

I have the honor to be, with high consideration, your lordship’s very obedient servant,

WILLIAM H. SEWARD.

Right Hon. Lord Lyons, &c., &c., &c.
