WORLD’S FAIRS. 315 _ THE AMERICAN CrYSTAL PALACE, URING the past half century a favorite and J effective method of displaying and recording the industrial progress of the world has been found in the holding of World’s Fairs or Universal Exhi- bitions. Almost every important capital of the world has now held one or more of these interesting displays, each in succession striving to outdo its pre- decessors in extent and magnificence, until the latest of them truly present in epitome the invention, indus- try, art, science, and general progress of the entire followed, and almost simultaneously with the exhibi- tion in the Irish metropolis a similar exhibition was opened in the capital of the Western Hemisphere. The American Crystal Palace, which was opened in New York in 1853, was in point of size much inferior to its prototype in London, and altogether insignificant when contrasted with the stupendous exhibitions of later years. For its time, however, it was porportionately equal to any that has ever been held. At that time New York City contained only WCRLD'S FAIR, NEW YORK, 1853. world. It was fitting that the first of these universal exhibitions should be held in the world’s chief city, London. It was opened in 1851 in a huge building erected in Hyde Park for the purpose, known as the Crystal Palace.

The develup- ment of the United States was still less advanced. What are now central Western States were then sparsely settled frontier territories. The Pacific railroads were a dream of the dim future. The Atlantic Cable was a vision. The telegraph itself was a mere rudiment of its present development. The railroad and the steamboat were primitive affairs. Even horse cars had not come into general use.
