TALL STRUCTURES.
The United States can boast of the tallest masonry structures in the world, although other countries have buildings and towers made of other materials that can outtop American attempts. The Washington Monument is 550 feet high; the tower of the Philadelphia City Hall is 537 feet high, and the Manhattan Life-insurance Building is 437 feet high. One of their rivals abroad is a chimney at Port Dundas in Scotland, the tallest in the world, which is 454 feet high. There are only two masonry structures in Europe that surpass it—the Cologne Cathedral, 510 feet, and the Strasburg Cathedral, 468 feet. The Pyramid of Ghizeh is about 480 feet high. The highest thing put up by man is, of course, the Eiffel Tower on the Champ de Mars in Paris, but this will have to yield its supremacy to the Great Davey Tower now being built near London. When completed that will rise 1250 feet into the air. The highest artificial structure in America is a water tower at Eden Park, near Cincinnati, which reaches a total height of 589 feet.
