One morning we decided to walk some distance up Clear Creek Cañon. At the opening of the cañon, Brewer's blackbirds were scuttling about in the bushes that broidered the steep banks of the tumultuous stream, and a short distance up in the gorge a lazuli bunting sat on a telegraph wire and piped his merry lay. Soon the cañon narrowed, grew dark and forbidding, and the steep walls rose high on both sides, compelling the railway to creep like a half-imprisoned serpent along the foot of the cliffs; then the birds disappeared, not caring to dwell in such dark, more than half-immured places. Occasionally a magpie could be seen sailing overhead at an immense height, crossing over from one hillside to the other, turning his head as he made the transit, to get a view of the two peripatetics in the gulch below, anxious to discover whether they were bent on brigandage of any kind. At length we reached a point where the mountain side did not look so steep as elsewhere, and we decided to scale it. From the railway it looked like a short climb, even if a little difficult, and we began it with only a slight idea of the magnitude of our undertaking. The fact is, mountain climbing is a good deal more than pastime; it amounts to work, downright hard work. In the present instance, no sooner had we gained one height than another loomed steep and challenging above us, so that we climbed the mountain by a series of immense steps or terraces. At places the acclivity was so steep that we were compelled to scramble over the rocks on all fours, and were glad to stop frequently and draw breath and rest our tired limbs. My boy comrade, having fewer things than I to lure him by the way, and being, perhaps, a little more agile as well, went far on ahead of me, often standing on a dizzy pinnacle of rock, and waving his butterfly-net or his cap in the air, and shouting at the top of his voice to encourage his lagging parent and announce his triumph as a mountaineer. However, the birdman can never forget his hobby. There were a few birds on that precipitous mountain side, and that lent it its chief attraction. At one place a spurred towhee flitted about in a bushy clump and called much like a catbird--an almost certain proof of a nest on the steep, rocky wall far up from the roaring torrent in the gorge below. On a stony ridge still farther up, a rock wren was ringing his peculiar score, which sounds so much like a challenge, while still farther up, in a cluster of stunted pines, a long-crested jay lilted about and called petulantly, until I came near, when he swung across the cañon, and I saw him no more.
