Having spent all the time I could spare at Glenwood, one morning I boarded the eastward-bound train, and was soon whirling up through the sublime cañons of Grand and Eagle Rivers, keeping on the alert for such birds as I could see from the car-window. Few birds, as has been said, can be seen in the dark gorges of the mountains, the species that are most frequently descried being the turtle doves, with now and then a small flock of blackbirds. The open, sunlit valleys of the upper mountains, watered by the brawling streams, are much more to the liking of many birds, especially the mountain song-sparrows, the white-crowned sparrows, the green-tailed towhees, and Audubon's and Wilson's warblers. Up, up, for many miles the double-headed train crept, tooting and puffing hard, until at length it reached the highest point on the route, which is Tennessee Pass, through the tunnel of which it swept with a sullen roar, issuing into daylight on the eastern side, where the waters of the streams flow eastward instead of westward. The elevation of this tunnel is ten thousand four hundred and eighteen feet, which is still about a thousand feet below the timber-line. A minute after emerging from the tunnel's mouth I caught sight of a red-shafted flicker which went bolting across the narrow valley. The train swept down the valley for some miles, stopped long enough to have another engine coupled to the one that had brought us down from the tunnel, then wheeled to the left and began the ascent to the city of Leadville. This city is situated on a sloping plain on the mountain side, in full view of many bald mountain peaks whose gorges are filled with deep snow-drifts throughout the summer. For some purposes Leadville may be an exceedingly desirable city, but it has few attractions for the ornithologist. I took a long walk through a part of the city, and, whether you will believe it or not, I did not see a single bird outside of a cage, not even a house-finch or an English sparrow, nor did I see one tree in my entire stroll along the busy streets. The caged birds seen were a canary and a cardinal, and, oddly enough, both of them were singing, mayhap for very homesickness. Why should a bird student tarry here? What was there to keep him in a birdless place like this? I decided to leave at once, and so, checking my baggage through to Buena Vista, I started afoot down the mountain side, determined to walk to Malta, a station five miles below, observing the birds along the way. Not a feathered lilter was seen until I had gone about a mile from Leadville, when a disconsolate robin appeared among some scraggy pine bushes, not uttering so much as a chirp by way of greeting.
