Mr. Seward to Lord Lyons.

My Lord: With reference to the subject of the detention of persons captured on vessels engaged in violating the blockade, I have the honor to invite your lordship’s attention to the accompanying extract from a despatch of the 1st instant, addressed to me by the consul general of the United States at Havana.

I have the honor to be, with high consideration, my lord, your obedient servant,

WILLIAM H. SEWARD.

Right Hon. Lord Lyons, &c., &c., &c.

[Extract.]

Mr. Savage to Mr. Seward.

No. 175.]

Sir: The steamers the Mail, alias Susanna, and the Ivanhoe, sailed on last Sunday and Tuesday, respectively. The Alice and the Virgin are about to sail for Mobile. The last three named, I understand, are almost entirely laden for [Page 661] account of the rebel government. Both the Ivanhoe and Virgin belong to George Wigg, of Nassau; and four other steamers, belonging to the same person, are expected here soon, to take to Mobile a large quantity (some $600,000 worth) of war materials, and other supplies, for the rebel authorities. The Harriet Lane, alias Lavinia, it is likely will go to Nassau to take a rebel officer, of whom I will speak in a separate communication.

I have been advised that it is quite possible that the uncaptured steamers hitherto running between Wilmington and Nassau will transfer themselves to this port to run between it and Mobile, for the reason that the worn-out railroads communicating with Wilmington render it extremely difficult to provide them with the requisite supply of cotton, and that the authorities there intend to use the railroads exclusively for military purposes.

Henry Hardy, who had been the chief engineer of the blockade-runner Austin, alias Donegal, returned here on the last trip of the steamer Eagle from New York. On the 31st of May I wrote to Mr. Murray, United States marshal, New York, per steamer Morning Star, that he was going as a passenger on that vessel. He did go in her. His brother William attempted to ship as chief engineer on the steamer Mexico, which I prevented, for the reason that he had been engineer on the Alice. He went in that capacity on the Mail, a few days ago, to Galveston.”

A very considerable number of men engaged in running the blockade are Americans, from the northern States, and do not seem to meet, when captured, with the punishment which their treason deserves. The steamer Eagle, on her last trip from New York, brought as passengers a portion of the officers and crew, among them Smith, the master of the steamer Donegal, recently captured by the gunboat Metacomet, and sent to Philadelphia. Smith is an American, and a northern man, though it is possible that he may have represented himself as being an Englishman. Godfrey, the commander of the notorious Dembigh, is also a northern man, born in Brunswick, Maine, where he had interests in several vessels at the breaking out of war. He is a very bitter secessionist, and, should he ever be captured, ought to be held in confinement till the termination of the war.

Hon. William H. Seward, Secretary of State.
