HAND-BOOK OF WASHINGTON. 125 ARLINGTON HOUSE. By this name was the mansion of George. Wash ington Park Custis designated. It occupies a commanding position on the Virginia side of the Potomac, nearly opposite Georgetown. The edi fice is extensive, elegant, and imposing, two hun dred feet above the water, and commands a very fine view of the Capitol. At this place were carefully preserved many rare and valuable pic tures and other relics, descended from the ances tors of Mr. Custis, and some of them onee in the possession of General Washington. When Gen eral La Fayette made his last visit to this country ho was a frequent guest at Arlington House. And in this connection it may not be deemed out of place to mention the fact that for many years Mr. Custis, during his life-time, was in the habit of printing-jn the National Intelligencer, on the anniversary of General Washington's birth day, a chapter of personal reminiscences respecting the illustrious Chief. During the rebellion this property has been confiscated by the Government and sold at public auction.
