Mr. Seward to Mr. Dayton.

No. 425.]

Sir: Your despatches of the 16th instant, (No. 363 and No. 364,) in relation to the iron-clad war ships in course of construction at Nantes and Bordeaux, have been received, with the translation of a communication of the 15th instant from M. Drouyn de l’Huys on that question.

I feel constrained to express my disappointment that the answer which has thus been made to your remonstrances on this grave subject was not more direct and conclusive. If Mr. Drouyn de l’Huys does not soon recur to it in a more satisfactory manner, you will be expected to follow it up and. to obtain an early reply. In your performance of this duty, previous instructions will furnish reasons which you will, in your discretion, use to promote the desired solution of the matter.

I am, sir, your obedient servant,

WILLIAM. H. SEWARD.

Wm. L. Dayton, Esq., &c., &c.
