Mr. Seward to Lord Lyons.

My Lord: I have the honor to invite your attention to the enclosed copy of a communication of the 25th instant, from the War Department, giving a copy of a report of the 22d instant from Major General Dix in regard to the existence of a military organization of insurgent fugitives from the United States in Canada.

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

WILLIAM H. SEWARD.

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

Mr. Dana to Mr. Seward.

Sir: The Secretary of War directs me to transmit for your information the en closed copy of a letter from Major General Dix, relative to the disturbed condition of the northern frontier.

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

C.A. DANA, Assistant Secretary of War.

Hon. William H. Seward, Secretary of State.

General Dix to Mr. Stanton.

Sir: I have the following reliable information: There are about forty rebels in Marysburg, Prince Edward’s county, Canada, on the north side of Lake Ontario, and northwest of Oswego. They drill regularly about three times a week, and are armed with revolvers. They board with the farmers in the neighborhood, [Page 813] seem to have plenty of money, and say they belong to John Morgan’s corps. These organizations for hostile purposes, on Canadian soil, are so plainly in violation of all the obligations of neutrality, that I cannot doubt the willing-ness of the Canadian authorities to put an end to them on proper notice.

There are some indications of retaliation on the part of our citizens along the frontier, on account of the outrages on the Detroit river and at St. Albans; and I think the publication of my report in regard to the former would have a salutary influence on both sides of the line.

I am, very respectfully, your obedient servant,

JOHN A. DIX Major General, New York.

Hon. E.M. Stanton, Secretary of War.
