"Centuries ago," said George W. Kelham, chief of Exposition architecture, "before the modern age of advanced specialization was dreamed of, had an architect been asked to create an exposition, he would have been not only an architect, but painter, sculptor and landscape engineer as well. He would have thought, planned and executed from this fourfold angle, and I doubt if it would have even occurred to him to think of one of the arts as detached from another." These words express the method of the Exposition builders. The scheme adopted was a unit, in which all of the arts were needed, and in which they all combined to a single end. Each building, each court, every garden and large mass of foliage, was designed as part of a balanced composition. To make the landscape an integral part of the Exposition picture, by fitting the Exposition to the landscape, was the common aim of architect, colorist, sculptor and landscape engineer. The Mediterranean setting offered by a sloping bench on the shore of the Golden Gate suggested, as most capable of high expression of beauty, the scheme of a city of the Far East, its great buildings walled in and sheltering its courts. The coloring of earth, sky and sea furnished the palette from which tints were chosen alike for palaces and gardens. The beauty of this plan is matched by its practical advantages. The compact grouping of the Exposition palaces not only meant a saving of ground and labor, but it makes it easier to handle the crowds, and lessens the walking required of the visitor. There is no monotony. In developing the general idea, each architect and artist was left free to express his own personality and imagination. The result is that varied forms and colors in the different courts and buildings blend truly into the whole picture of an Oriental city, set in the midst of a vast amphitheater of hills and bay, arched by the fathomless blue of the California sky.
