Ah! my propitious stars shone on me that day with special favor. I had found not only the water-ousel itself, but also its nest. Suddenly water-ousel number two, the mate of number one, appeared on the scene, dipped, scanned me closely, flew to the slippery wall, darted to the cranny, and deposited its morsel, as its spouse had done. This time I heard the chirping of the youngsters. Before examining the nest I decided to watch the performances of the parent birds, which soon cast off all the restraint caused for a moment by my presence, taking me, no doubt, for the ordinary sightseer who overlooks them altogether. Again and again the birds plunged into the churning flood at the foot of the falls, sometimes remaining under water what seemed a long while, and always coming to the surface with a delicacy for the nestlings. They were able to dip into the swift, white currents and wrestle with them without being washed away. Of course, the water would sometimes carry them down stream, but never more than a few inches, and never to a point where they could be injured. They were perfect masters of the situation. They simply slipped in and out like living chunks of cork. Their coats were waterproof, all they needed to do being to shake off the crystal drops now and then. Their flight up the almost perpendicular face of the falls was one of graceful celerity. Up, up, they would mount only a few inches from the dashing current, and disappear upstream in search of food. In returning, they would sweep down over the precipitous falls with the swiftness of arrows, stopping themselves lightly with their outspread wings before reaching the rocks below. From a human point of view it was a frightful plunge; from the ousel point of view it was an every-day affair. [Illustration: _Water-Ousel_ "_Up, up, only a few inches from the dashing current_"]
