In 1926 a new elevator was installed. It is of the electrically driven, gearless, single wrap, traction type, with a speed of 500 feet per minute and a lifting capacity of 6,000 pounds, exclusive of the weight of the car and cables. It is equipped with a micro-leveling device, which insures exact leveling of the car at landings and also makes possible the operation of the elevator at slow speed in case of failure of the main motor, thus eliminating the danger of stalling the car between landings. It accommodates 30 persons and makes 12 trips per hour. There are 8 windows at a height of 504 feet above ground--2 windows in each of the 4 faces of the pyramidion--4 feet above the 500-foot landing. These windows measure 18 inches by 3 feet on three sides, and on the east side 2 feet by 3 feet. Looking to the east from the windows one sees the stately Capitol; to the north, across the President’s Park, the beautiful mansion of the Chief Magistrate; to the northeast, the Soldiers’ Home; to the northwest, the great residential section, the Naval Observatory, and the Washington Cathedral; to the west the beautiful Potomac River, as it winds its way for miles past the city, and Arlington National Cemetery, the Nation’s most sacred resting place for those who served in defense of their country; and as we follow the Potomac southward there is Alexandria, 6 miles beyond, and in the faint distance Mount Vernon, where is the tomb of the immortal Washington. And on that lofty height, the greatest single piece of masonry in the world, we think also of other high structures--the Empire State Building, with 86 stories, 1,248 feet; Chrysler Building, 68 stories, 1,046 feet; Bank of Manhattan, 65 stories, 838 feet; Woolworth Tower 60 stories, 792 feet; Metropolitan Life Insurance Building, 700 feet; The New York Life Insurance Building, 610 feet, at the site of the former famous Madison Square Garden; Singer Tower, 612 feet; spires of Cologne Cathedral, 524 feet; spire of Old St. Paul’s, London, 508 feet; Pyramids of Cheops, 480 feet; Book Tower, Detroit, 472 feet; Victoria Tower, Westminster, 325 feet; Statue of Liberty, 317 feet; Bennington Battle Monument, 306 feet; the Capitol, 287 feet; Bunker Hill Monument at Boston, 221 feet. In 1890 Daniel H. Burnham completed the Masonic Temple, in Chicago, “the tallest building in the world,” 21 stories high, among the first of all-steel construction. In New York City the caisson for high-building foundation work was first adopted in the Manhattan Life Insurance Building, near Exchange Place on Broadway, in 1894. Built on a foundation of bedrock 55 feet below the surface, the structure of 18 stories was built 350 feet in height from the sidewalk.
