A little later a grown bird appeared, that I supposed at first was the returning papa, but a few moments' observation convinced me that it was the mother; partly because no song accompanied the work, but more because of the entirely different manners of the new-comer. Filling the crop of that importunate offspring of hers was, with this Quaker-dressed dame, a serious business that left no time for rest or recreation. Two charmed hours I sat absorbed, watching the most wonderful evolutions one could believe possible to a creature in feathers.

At the point where this little drama was enacted, the brook rushed over a line of pebbles stretching from bank to bank, lying at all angles and of all sizes, from six to ten inches in diameter. Then it ran five or six feet quietly, around smooth rocks here and there above the water, and ended by plunging over a mass of bowlders to a lower level. The bird began by mounting one of those slippery rounded stones, and thrusting her head under water up to her shoulders. Holding it there a few seconds, apparently looking for something, she then jumped in where the turmoil was maddest, picked an object from the bottom, and, returning to the ledge, gave it to baby.

The next moment, before I had recovered from my astonishment at this feat of the ouzel, she ran directly up the falls (which, though not high, were exceedingly lively), being half the time entirely under water, and exactly as much at her ease as if no water were there; though how she could stand in the rapid current, not to speak of walking straight up against it, I could not understand.

Often she threw herself into the stream, and let it carry her down, like a duck, a foot or two, while she looked intently on the bottom, then simply walked up out of it on to a stone. I could see that her plumage was not in the least wet; a drop or two often rested on her back when she came out, but it rolled off in a moment. She never even shook herself. The food she brought to that eager youngling every few minutes looked like minute worms, doubtless some insect larvæ.

Several times this hard-working mother plunged into the brook where it was shallow, ran or walked down it, half under water, and stopped on the very brink of the lower fall, where one would think she could not even stand, much less turn back and run up stream, which she did freely. This looked to me almost as difficult as for a man to stand on the brink of Niagara, with the water roaring and tumbling around him. Now and then the bird ran or flew up, against the current, and entirely under water, so that I could see her only as a dark-colored moving object, and then came out all fresh and dry beside the baby, with a mouthful of food. I should hardly dare to tell this, for fear of raising doubts of my accuracy, if the same thing had not been seen and reported by others before me. Her crowning action was to stand with one foot on each of two stones in the middle and most uproarious part of the little fall, lean far over, and deliberately pick something from a third stone.

All this was no show performance, even no frolic, on the part of the ouzel,—it was simply her every-day manner of providing for the needs of that infant; and when she considered the duty discharged for the time, she took her departure, very probably going at once to the care of a second youngster who awaited her coming in some other niche in the rocks.

Finding himself alone again, and no more dainties coming his way, the young dipper turned for entertainment to the swift-running streamlet. He went down to the edge, stepping easily, never hopping; but when the shallow edge of the water ran over his pretty white toes, he hastily scampered back, as if afraid to venture farther. The clever little rogue was only coquetting, however, for when he did at last plunge in he showed himself very much at home. He easily crossed a turbulent bit of the brook, and when he was carried down a little he scrambled without trouble up on a stone. All the time, too, he was peering about after food; and in fact it was plain that his begging was a mere pretense,—he was perfectly well able to look out for himself. Through the whole of these scenes not one of the birds, old or young, had paid the slightest attention to me, though I was not ten feet from them.

During the time I had been so absorbed in my delightful study of domestic life in the ouzel family, the other interesting resident of the cañon—the elusive cañon wren—had been forgotten. Now, as I noticed that the day was waning, I thought of him again, and, tearing myself away from the enticing picture, leaving the pretty baby to his own amusements, I returned to the famous Pillars, and planted myself before my rock, resolved to stay there till the bird appeared.

No note came to encourage me, but, gazing steadily upward, after a time I noticed something that looked like a fly running along the wall. Bringing my glass to my eyes, I found that it was a bird, and one of the white-throated family I so longed to see. She—for her silence and her ways proclaimed her sex—was running about where appeared to be nothing but perpendicular rock, flirting her tail after the manner of her race, as happy and as unconcerned as if several thousand feet of sheer cliff did not stretch between her and the brook at its foot. Her movements were jerky and wren-like, and every few minutes she flitted into a tiny crevice that seemed, from my point of view, hardly large enough to admit even her minute form. She was dressed like the sweet singer of yesterday, and the door she entered so familiarly was the same I had seen him interested in. I guessed that she was his mate.

The bird seemed to be gathering from the rock something which she constantly carried into the hole. Possibly there were nestlings in that snug and inaccessible home. To discover if my conjectures were true, I redoubled my vigilance, though it was neck-breaking work, for so narrow was the cañon at that point that I could not get far enough away for a more level view.
