EXECUTIVE ORDERS.

WASHINGTON CITY,

The SECRETARY OF WAR.

MY DEAR SIR:  I have just issued an authority to Hugh Maxwell, collector at New York, under the eighth section of the act of April 20, 1818, to arrest any unlawful expedition that may be attempted to be fitted out within his district, and I have given him power to call upon any military and naval officers that may be there to aid him in the execution of this duty; and I will thank you to issue the necessary instructions to the proper military officer in that district.

I am, your obedient servant,

MILLARD FILLMORE.

WASHINGTON CITY,

Tuesday, June 29, 1852—­12.30 o’clock p.m.

SIR:[26] The tolling bells announce the death of the Hon. Henry Clay.  Though this event has been long anticipated, yet the painful bereavement could never be fully realized.  I am sure all hearts are too sad at this moment to attend to business, and I therefore respectfully suggest that your Department be closed for the remainder of the day.
