On either side spreads out the city, the houses bordering the foliage-lined streets, and having at frequent intervals the tall spires of churches, and the massive marble, granite and brick edifices that are used for Government buildings. In front, to the west, is the wide channel of the Potomac, and to the south and southeast the Anacostia, their streams uniting at Greenleaf's Point, where the Government Arsenal is located. On the heights beyond the point, and across the Anacostia, is the spacious Government Insane Asylum. Far away on the Virginia shore, across the Potomac, rises a long range of wooded hills, amid which is Arlington Heights and its pillared edifice, which was the home of George Washington Parke Custis, the grandson of Mrs. Washington and General Washington's adopted son, and was subsequently the residence of General Robert E. Lee, who married Miss Custis. Spreading broadly over the forest-clad hills is the Arlington National Cemetery, where fifteen thousand soldiers of the Civil War are buried. At the distant horizon to the left rises the spire of Fairfax Seminary, and beyond, down the Potomac, is seen the city of Alexandria, the river between being dotted with vessels. To the northwest, behind the Executive Mansion, is the spacious building of the State, War and Navy Departments, having for a background the picturesque Georgetown Heights, just over the District boundary, their tops rising four hundred feet above the river. Farther to the northward is Seventh Street Hill, crowned with the buildings of Howard University, and beyond it the distant tower of the Soldiers' Home. All around the view is magnificent; and years ago, before the city expected to attain anything like its present grandeur, Baron von Humboldt, as he stood upon the western verge of Capitol Hill and surveyed this gorgeous picture, exclaimed: "I have not seen a more charming panorama in all my travels."
