Mr. Seward to Mr. Mercier.

Sir: I have not yet received from Mr. De Long, our consul at Tangier, a perfect report of the arrest and other proceedings there in regard to the pirates of the Sumter. So soon as I obtain the needed information, I will ask the attention of the President to the view of that transaction submitted to me by you in our conversation of yesterday.

I avail myself of this opportunity to renew to you, sir, the assurance of my high consideration.

WILLIAM H. SEWARD.

Mr. Henry Mercier, &c., &c., &c.
