Du Mond's two murals in the western arch are easier. They make a continuous story. The first chapter, on the north side, pictures the emigrant train, led by the Spirit of Adventure, leaving for the West, while the second shows the pioneers reaching the shores of the Pacific and welcomed by California. To express the many-sided development of the West, Du Mond has portrayed individuals as the types of the pioneers. Here are Junipero Serra, the priest; Anza, the Spanish captain who first trod the shores of San Francisco Bay; Joseph Le Conte, the scientist; Bret Harte, the author; William Keith, the artist; and Starr King, the divine. The energy of these men has actually outstripped the Spirit of Adventure. Du Mond's story parallels in a way that pictured by Simmons. Color and composition are both exceedingly grateful to the eye. The Column of Progress, outside the court, commands the entire north front of the Exposition, as the Tower of Jewels does the southern. (p. 57.) Symmes Richardson, the architect, drew his inspiration from Trajan's Column at Rome, an inspiration so finely bodied forth by the designer and the two sculptors who worked with him, MacNeil and Konti, that this shaft stands as one of the most satisfying creations on the Exposition grounds. Its significance completes the symbolism of the Exposition sculpture and architecture, as the joyous Fountain of Energy at the other end of the north-and-south axis begins it. That fountain celebrates the completion of the Canal. The Tower of Jewels with its sculpture tells the historical story of the conquest of the western seas and their shores. The Court of the Universe is the meeting place of the Nations, come to commemorate the joining of East and West. From this Court, a splendid avenue leads down to the border of the Western Ocean, where stands the Column of Progress, beyond the Exposition. Both in its position and in its sculpture the column signifies that, this celebration over, human endeavor stands ready to go on to still vaster enterprises on behalf of mankind. The figure atop this Column is the Adventurous Bowman, past human achievement behind him, seeking a new emprise in the West, whither he has loosed his arrow. At his back is a figure of Humanity, signifying the support of mankind. By his side is the woman, ready to crown his success. (p. 58.) The question has often been asked, why there is no string to the archer's bow. The sculptor properly omitted it, for, at the moment the arrow leaves the bow, the cord is vibrating far too strongly to be visible. The cylindrical frieze below the Bowman represents the Burden Bearers. This, with the Bowman, is the work of H. A. MacNeil. The spiral of ships ascending the shaft symbolizes the upward course of man's progress. Around the base is the frieze by Isidor Konti, on three sides striving human figures, on the fourth celestial trumpeters announcing victory. The whole signifies man's progress through effort. (p. 60.)
