Mr. Seward to Mr. Haldeman.

No. 35.]

Sir:Your despatch of December 3, No. 39, has been received. We observe, not without interest, the progress of the controversy concerning the duchy of Holstein, which is now engaging so deeply the attention of the European cabinets. You will, therefore, accept my sincere thanks for the information you have given me on that subject.

I have laid before the Secretary of the Navy so much of your despatch as relates to the suspected sale of a steamer in Sweden or Denmark. I have also directed the attention of our minister at London to the consul’s statement, that the steamer is expected to be prepared in some British harbor, with a view to run the blockade in some of our southern ports.

I am, sir, your obedient servant,

WILLIAM H. SEWARD.

Jacob S. Haldeman, Esq., &c., &c., &c., Stockholm.
