TRAFALGAR SQUARE, LOOKING DOWN WHITEHALL.
From the middle of the Terrace in front of the National Gallery, the Clock Tower of the Houses of Parliament is seen rising beyond broad and stately Whitehall Between the plashing fountains, which are so delightful a feature of Trafalgar Square, with face towards the Nelson Column, is Mr. Hamo Thornycroft's excellent statue of General Gordon, erected in 1888. The height of the Nelson column, 145 feet, or 162 feet if Bailys heroic statue of the hero on its summit be included, is most easily realised from this point of view. The road to the left in our view is Northumberland Avenue, so called because Northumberland House, the grand old residence of the Percy family, formerly stood on the site. To the right is Cockspur Street, leading to Pall Mall.
