tion and witnessing the extraordinary magnitude of the undertaking. We are told that the approximate cost is $50,000,000, the size of the grounds 1,240 acres, and the area of the buildings 200 acres. It is consequently planned on a scale much surpassing the expositions of Philadelphia, Chicago and Paris. The making of expositions is becoming a sort of applied science, each showing progress over its predecessors. A large proportion of the chiefs of departments and others in charge of the work at St. Louis have been trained at previous expositions.

An exposition is both interesting and tiring, whereas a description is likely to be tiring without being interesting. The subjoined plan gives some idea of the arrangement of the buildings, their number and their size. An enumeration of the buildings shows clearly that the whole undertaking is an apotheosis of applied science, extending even to the shows along 'The Pike.' Education has been given a central place, both in the position of the building, the first to form part of an exposition, and in the classification of the exhibits. The exposition and education are also fortunate in the fact that the new buildings of Washington University are on the grounds. We are glad to be able to publish elsewhere in this number a description of the university which is rapidly becoming one of the great universities of the country. The art gallery is also a permanent building, erected with its temporary annexes at the cost of over a million dollars.
