In the panel of "The Survival of the Fittest" the battle of life is at its height. The men are in a furious struggle of strength and prowess. The interplay of human passions, the contests of wills and capacities, has developed. The women, too, are taking a conscious part in life, one weeping and shrinking from the fray, the other extending a restraining hand. In the last and noblest panel, called "The Lesson of Life," we see the spiritualized and intellect-guided emotions. A helmeted man and pure-browed woman gaze tenderly in each other's eyes. Youth, full of impulse and fire, stays to listen to the voice of Reason. The lover keeps in touch with the guiding memory of the Mother. And the cycle is completed from animal to mental toward the higher foundation of life upon the earth. Seldom has more exaltation of thought or intensity of feeling been infused, without mawkishness or exaggeration, into a work of art. The Fountain of Earth, is deeply interpretive of the trend of modern thought. Helios Separate Group, Fountain of Earth On the wall of the basin of the Fountain of Earth, is a subsidiary group called "Helios, the Sun." It is a decorative point of finish and is also symbolic. The Sun is taken as the symbol of the Cosmos, the enduring, the Day, the source of life. Man is pictured as clinging to it, in the hope of being freed from the encircling coils of his baser self and the old earthy entanglements that hold him down, and destroy him. This group and the main fountain, as well as the sides of the beautiful court, are mirrored in the long still pool in which the fountain stands - a pool properly free from splashes or springs as befits the setting of this intricate and massive work. The rapid and stable growth of Robert I. Aitken, sculptor of the Fountain of Earth, is of particular interest to San Francisco, the city of his birth, and the site of several of his earlier efforts. Water Sprites Base of Column, Court of Ages The "Water Sprite Columns" in the Court of Ages bring the somber symbolism of this court back to the gay spirit of festival. The sprites are the work of Leo Lentelli; they have a quaint elfin quality that is very engaging. The amusing and lovely group seated about the base of the column have a certain chic habit of pointing elbows, wrists and ankles that lends an unworldly attraction. Their sister sprite at the top of the slender decorated shaft is mischievously aiming an arrow downwards. These Sprite Columns express the gay, frolicsome mood of the waters. Their feeling harmonizes more with the sea-weed and shell decorations of the court itself and its falling-water motif than with the weightier sculpture it contains. They create a pleasing ripple of merriment. Their light and airy modeling has the beauty of unconscious and unforced artistry. The columns stand just within the northern entrance of the court, guarding a vista of the bay. A Daughter of the Sea North Aisle, Court of Ages
