The death of this distinguished public officer, especially at the present moment, when his eminent services are so much needed, is a great loss to his country.  He was able, honest, and indefatigable in the discharge of his high and responsible duties, whilst his benevolent heart and his kind deportment endeared him to all who approached him.

Submitting, as I do, with humble resignation to the will of Divine Providence in this calamitous dispensation, I shall ever cherish his memory with affectionate regard.

JAMES BUCHANAN.

EXECUTIVE ORDERS.

[From the Evening Star, March 10, 1859.]

GENERAL ORDER.

WAR DEPARTMENT,

Washington, March 8, 1859.

Under instructions from the President of the United States, the Secretary of War with unfeigned sorrow announces to the Army the decease of the Hon. A.V.  Brown, Postmaster-General, which occurred in this city at an early hour this morning.

An enlightened statesman and a distinguished and able member of the General Government has thus been stricken down at his post.  The nation will mourn the afflicting dispensation which has left so great a void in its councils.  A worthy and estimable citizen has been removed from the circle of his numerous friends.  Society will mingle its grief with the patriotic regrets which the loss of a statesman will not fail to call forth.

While the President, with the surviving members of the Cabinet, the legislative and judicial departments of the Government, will unite in every testimonial the sad occasion demands, it is fitting a similar respect should be shown to the memory of the distinguished deceased by the national arms of defense.  Accordingly, half-hour guns will be fired from sunrise to sunset at every garrisoned military post the day succeeding the receipt of this order, the national flag will be displayed at half-staff during the same time, and officers of the Army will wear for three months the proper badge of military mourning.

The War Department and its bureaus will be closed until the day succeeding the funeral obsequies.

JOHN B FLOYD,

Secretary of War.

As a mark of respect to his high character, his eminent position, and great public services, it is directed that on the day after the receipt of this order by the different navy-yards and stations and vessels of war of the United States in commission the flags be hoisted at half-mast from sunrise to sunset and that seventeen minute guns be fired at noon.
