Mr. Seward to Mr. Dayton.

No. 245.]

Sir: The Steamer having been detained by adverse winds, the incoming mail arrives just at the moment when the outgoing one is being closed. A special notice of your despatches must therefore be delayed.

The military and naval movements in all directions are onward and satisfactory. Those who in Europe are reckoning that the situation is to remain unchanged will discern their error in time, it is hoped, to change the policy they seem now to be pursuing.

I am, sir, your obedient servant,

WILLIAM H. SEWARD.

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