299 F STREET, Washington, September 24, 1861.

Honorable WILLIAM H. SEWARD, Secretary of State.

SIR: Since the arrest of William G. Harrison, of Baltimore, a member of the Legislature of Maryland, I hae had occasion to efer to a letter from which in reply to one of mine inquiring why he had not presented a petition which I had sent to him in relation to the capture of M. C. Causten by an armed band from Virginia.

The reason for not presenting my memorial that "the Federal relations of the Stae were such that I did not present it" of course made me very indignant and I did not reply to him, as I could not in a temperate style for we had been shcoolmates nearly fifty years ago. Now I consider it myduty to transmit his note and my original petition to you, as in my humble opinion it shows his animus in relation to the Federal Government. More than forty years since I took an oath to support the Constitution of the United States and I have repeated it on many occasions and will keep it.

Now, my dear sir, on behalf of thousands of distressed individuals who have relatives and friends prisoners to the Confederates as they call themsevles I pray you to adopt some course by which they may return to their homes. The late accounts from the South state the Union prisoners are being sent to New Orleans and Charleston where of course nearly half of them may be carried off by the yellow fever.

With great respect, I have the honor to remain, your obedient servant,

McCLINTOCK YOUNG.

P. S. -As I am a perfect stranger to you I would merely state that I was for many years chief clerk of the Treasury Department and often perfomred the duties of the head of the Department by appointments of Presidents Jackson, Van Buren, Tyler, Polk and Taylor.

McC. YOUNG, Esq., Washington.

MY DEAR SIR: In reply to your request under date 5th instant I now return to you the memorial sent me to present. The Federal relations of the State were such that I did not present it.

Very truly,

WM. G. HARRISON.
