Mr. Adams to Mr. Seward.

No. 591.]

Sir: The question on the appeal from the decision of the court of exchequer in the case of the Alexandra will come up for consideration on Saturday next, before the court of exchequer chamber, composed of eight judges, and four from the court of common pleas. Mr. Evarts, who has been in Paris for a few days past, will probably be here in season to watch the case on behalf of the government, and make his report to you.

The activity in sending out vessels to run the blockade continues, though it seems now to be understood that a larger proportion of each risk is assumed by the rebel authorities. It has just been reported to me, from a secret source, that the steamer called the Kangaroo is about to depart, with a considerable number of rebel passengers, including Messrs. Mason and Slidell, and a large sum in money, but with no other freight. Should this prove to be true, you will probably get by this steamer more exact information from another source.

I have the honor to be, sir, your obedient servant,

CHARLES FRANCIS ADAMS.

Hon. William H. Seward &c., &c., &c.
