HARRISBURG, PA., May 25, 1862.

E. M. STANTON,

Secretary of War:

The organization of volunteers has been in progress all day in Philadelphia. From movements since the defeat of Banks I have reason to apprehend a design to cross into Cumberland Valley. I suggest whether out present available force had not better be thrown in that direction. There is a great alarm on the border, and I have dispatches from our troops at Hagerstown, who have retreated there without arms. I cannot reach the interior of the State by telegraph until to-morrow.

WASHINGTON, May 26, 1862.

To the SENATE AND HOUSE OF REPRESENTATIVES:

The insurrection which is yet existing in the United States, and aims at the overthrow of the Federal Constitution and the Union, was clandestinely prepared during the winter of 1860 and 1861, and assumed an open organization in the form of a treasonable Provisional Government at Montgomery, in Alabama, on the 18th day of February, 1861. On the 12th day of April, 1861, the insurgents committed the flagrant act of civil war by the bombardment and capture of Fort Sumter, which cut off the hope of immediate conciliation. Immediately afterward all the roads and avenues to this city were obstructed, and the capital was put into the condition of a siege. the mails in every direction were stopped, and the lines of telegraph cut off by the insurgents, and military and naval forces, which had been called out by the Government for the defense of Washington, were prevented from reaching the city by organized and combined treasonable resistance in the State of Maryland. There was no adequate and effective organization for the public defense. Congress had indefinitely adjourned. There was no time to convene them. It became necessary for me to choose whether, u sing only the existing means, agencies, and processes which Congress had provided, I should let the Government fall at once into ruin, or whether, availing myself of the broader powers conferred by the Constitution in cases of insurrection, I would make an effort to save it with all its blessings for the present age and for posterity. I thereupon summoned by constitutional advisers-the heads of all the Departments-to meet on Sunday, the 20th [21st] day of April, 1861, at the office of the Navy Department, and then and there, with their unanimous concurrence, I directed that an armed revenue cutter should proceed to sea, to afford protection to the commercial marine, and especially the California treasure ships, then on their way to the coast. I also directed the commandant of the navy-yard at Boston to purchase or charter, and arm as quickly as possible, five steam-ships, for purposes of public defense. I directed the commandant of the navy-yard at Philadelphia to purchase, or charter and arm, an equal number for the same purpose. I directed the commandant at New York to purchase, or charter and arm, and equal number. I directed Commander Gillis to purchase, or charter and arm, and put to sea two other vessels. Similtar directions were given to Commodore Du Pont with a view to the opening of passages by water to and from the capital. I directed the several officers to take the advice and obtain the aid and efficient
