Vitality and exuberance, guided by a distinct sense of order, are the dominant notes of the Arts of the Exposition and pre-eminently of the sculpture. It proclaims with no uncertain voice that "all is right with this Western world" - it is not too much to claim that it supplies the humanized ideality for which the Exposition stands - the daring, boasting masterful spirits of enterprise and imagination - the frank enjoyment of physical beauty and effort - the fascination of danger; as well as the gentler, more reverent of our attitudes, to this mysterious problem that is Life. One of the strongest influences the sculpture will have will be in the direction of a new impulse to inventive decoration. This field has remained relatively undeveloped, partly owing to our fondness for the portrait idea, but the direction is legitimate and worthy. Architecture, which is the growth of a selective precedence, must be continually supplied with new impulses - new blood to re-energize, rehumanize its conventions - and on the other hand, all such new impulses must be trained into order with architecture. Within the last few years a school devoted to the development of this, as it might be styled, applied sculpture, has been maintained by a group of public-spirited architects under the management of the Society of Beaux Arts Architects and the National Sculpture Society of the United States of America. The Star Goddess on the colonnades of the Court of the Universe amounts to a definite creation of a new type of repeated architectural finial - a human figure conventionalized to be come architecturally static - yet not so devitalized as to be inert. Based on another style of architecture the finials of the cloister of the Court of Ages serve a correspondingly related purpose, and the crouching figures on columns in this court are excellent examples of decorative crestings. The groups of the Nations of the East and the Nations of the West are new types in motif and composition of arch-crowning groups - to be seen in silhouette against the sky at all points. Both of these are grandly successful solutions of problems never before attempted since the ancients imposed the quadriga form of composition. They were first of all made possible by the receptive attitude of the distinguished architects, Messrs. McKim, Mead and White - which proves conclusively to me that those who are most versed in the various forms of antique arts are also those who are most capable of accepting the application of new motifs when sufficiently proven, and of quickly assimilating genuine contributions to the growth of progressive art. By so doing they lend to them all that wealth of refined elegance that has come down through the ages. This acceptance in itself is fraught with much encouragement to the growing school of public sculpture that aims to understand the principles of co-operation and to weld them to an ideal.
