As the Earth panels are luxuriant, teeming with a sense of plentitude, and the Fire panels are moving with the grace of rising smoke, those that represent the phases of Water are moist and lush. In the one here shown, "The Fountain," people have come through the damp grasses, bearing their bright vessels to fill them with water that flows downward from a spring in a long, fine, curving bow. The beautiful grouping, the pose of the figures and the graceful lines of the vessels are unforgettable. The air is fluid; great white clouds stretch across the sky, which has the same liquid beauty as the water in the background. Water-birds and dewy flowers add life and color. The grateful use of water for man's thirst is beautifully told. In the other water panel, "The Net," hardy fishermen, standing in the water-reeds and blossoming flag-lilies, haul in the last catch of the brightly dying day. Others bear on their heads baskets heavy with the success of earlier castings. Heavy sea-clouds are tinted by the late afternoon sunshine. Air The Windmill, Court of Ages The two panels of Air may well be thought of as the air that moves and the air that supports. In the first, "The Windmill," which is illustrated, the motion of the wind and of the world it blows is dazzling. The field of, golden grain, bright in the glow of the sun that has just broken through the rain clouds, is quivering with graceful undulations. The great wings of the windmill turn, with flapping sails. The little kites are blown tempestuously. The garments of the workers wave forward as they walk, braced against the wind that blows from behind them. A brilliant rainbow and wind-blown dark rain-clouds tell the end of a passing storm. In the second Air panel, which is called "The Hunters," the air supports the arrows just shot from the bows of hunters who hide behind the last trees at the edge of a wood. It bears also flocks of homing birds and light clouds blown across a ruddy sunset sky. Half Dome Court of the Four Seasons
