" He had entered an endless subterranean cavern, where jeweled rocks loomed out of the spectral gloom like marine plants, the sprays of glass forming white fountains. Several times he crossed and recrossed the road. The spurs were almost waist-high, and he was forced to climb over the brittle stems. Once, as he rested against the trunk of a bifurcated oak, an immense multi-colored bird erupted from a bough over his head, and flew off with a wild screech, aureoles of light cascading from its red and yellow wings. At last the storm subsided, and a pale light filtered through the stained-glass canopy. Again, the forest was a place of rainbows, a deep, iridescent light glowing from within. "
