Mr. Seward to Mr. Haldeman.

No. 30.]

Sir: I enclose herewith a transcript of a despatch, dated the 22d ultimo, from Mr. Tefft, our consul at Stockholm, relative to the visit to that city of Mr. Joseph Spence, of the firm of Pile, Spence & Co., ship-builders, of England, with the object, it is surmised, of procuring in Sweden armaments for vessels built in England for the confederate service.

The President confidently relies upon your well-known vigilance and activity, as well as upon the friendly disposition of the Swedish government, to prevent the carrying into effect of any such designs.

I am, sir, your obedient servant,

WILLIAM H. SEWARD.

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