Mr. Seward to Lord Lyons.

My Lord: I have the honor to acknowledge the receipt of your note of yesterday, asking for certain authentic information respecting the trade between the Atlantic and Pacific ports of the United States, by way of the isthmus of Panama, and to state that it has been referred to the Secretary of the Treasury, with a view to his enabling me to satisfy the inquiry.

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

WILLIAM H. SEWARD.

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