The space of time in which a great work can now be accomplished is not marvelous. Brain, muscle, materials, and the means of rapid transport are instantly at command. If one has capital and a well-considered plan, the thing does itself. But that which is wonderful and which I can scarcely believe, although I have been in the midst of it, is the noble, artistic result which has come from the work of American artists who have had only a few months' time to prepare those very designs for the great buildings of the Exposition which have actually been executed with little change from the sketches which were presented in February, 1891.
