Turtle doves were also plentiful in the valley above Malta, as they were in most suitable localities. Here were also several western robins, one of which saluted me with a cheerful carol, whose tone and syllabling were exactly like those of the merry redbreast of our Eastern States. I was delighted to find the sweet-voiced white-crowned sparrows tenants of this valley, although they were not so abundant here as they had been a little over a week before in the hollows below the summit of Pike's Peak. But what was the bird which was singing so blithely a short distance up the slope? He remained hidden until I drew near, when he ran off on the ground like a frightened doe, and was soon ensconced in a sage bush. Note his chestnut crest and greenish back. This is the green-tailed towhee. He is one of the finest vocalists of the Rocky Mountains, his tones being strong and well modulated, his execution almost perfect as to technique, and his entire song characterized by a quality that might be defined as human expressiveness. A pair of western chipping sparrows were feeding their young in one of the sage bushes. I hoped to find a nest, but my quest simply proved that the bantlings had already left their nurseries. It was some satisfaction, however, to establish the fact at first hand that the western chipping sparrows breed at an elevation of nine thousand five hundred and eighty feet above sea-level. While strolling about a short distance above the town, I discovered an underground passage leading to some of the factories, or perhaps the smelting works, a few miles farther up the valley. The over-arching ground and timbers forming the roof were broken through at various places, making convenient openings for the unwary pedestrian to tumble through should he venture to stroll about here by night. Suddenly a little broad-shouldered bird appeared from some mysterious quarter, and flitted silently about from bush to bush or from one tussock of grass to another. To my surprise, he presently dropped into one of the openings of the subterranean passage, disappeared for a few moments, and then emerged from another opening a little farther away. The bird--let me say at once--was Say's phoebe, with which, as previously told, I made acquaintance at Glenwood. He may be recognized by the reddish or cinnamon-brown cast of his abdomen and sides. Again and again he darted into the passage, perhaps to make sure that his bairns had not been kidnapped, and then came up to keep a vigilant eye on his visitor, whom he was not wholly disposed to trust. I am not sure that there was a nest in the subterranean passage, as my time was too short to look for it. Others may not regard it as an important ornithological discovery, and I do not pretend that it was epoch-making, but to me it was at least interesting to find this species, which was new to me, dwelling at an elevation of five thousand seven hundred and fifty-eight feet on the
