It was early determined that the great Fair should be one of processes, as well as of products; wherever possible there should be life and motion; that the exhibits should answer the question, "How is it done?" as well as "What is it?" The result was that the Exposition became a constantly changing scene of moving objects and an educational force many times greater than any of its predecessors. The student of Mechanics, Electricity, Pedagogy, the Applied Arts, and other kindred subjects could obtain here within a limited area valuable data, which otherwise could only be collected at the expense of much time and considerable money.

ADDRESS OF PRESIDENT ROOSEVELT. The address of President Roosevelt was replete with historical allusions and pointed epigrams. He drew many lessons from the valor and patriotism of the early settlers of the west, and said, among other things:
