A dreamy roar of water rushing over rocks rang in the traveler's ears.

It receded at times, then grew louder.

Presently the forest shade ahead lightened and he rode out into a wide space where green moss and flags and flowers surrounded a wonderful spring-hole.

Sunset gleams shone through the trees to color the wide, round pool.

It was shallow all along the margin, with a deep, large green hole in the middle, where the water boiled up.
