As I have said already, his presence was unexpected. His name is not included in Mr. Brewster’s North Carolina list, and I saw no other bird like him till I was approaching Asheville, a week later, in a railway train. Then I was struck almost at the same moment by two things--a brick chimney and a barn swallow. My start at the sight of red bricks made me freshly aware with what quickness the mind puts away the past and accustoms itself to new and strange surroundings. Man is the slave of habit, we say; but how many of us, even in middle age, have altered our modes of living, our controlling opinions, or our daily occupations, and in the shortest while have forgotten the old order of things, till it has become all like a dream,--a story heard long ago and now dimly remembered. Was it indeed we who lived there, and believed thus, and spent our days so? This capacity for change augurs well for the future of the race, and not less for the future of the individual, whether in this world or in another. In a previous chapter I have mentioned as provocative of astonishment the ignorance of a North Carolina man, my driver from Walhalla, who had no idea of what I meant by “swallows.” His case turned out to be less singular than I thought, however, for when I spoke of it to an exceptionally bright, well-informed farmer in the vicinity of Highlands, he answered that he saw nothing surprising about it; _he_ didn’t know what swallows were, neither. Martins he knew,--purple martins,--though there were none hereabout, so far as I could discover, but “swallow,” as a bird’s name, was a novelty he had never heard of. Here on Stewart’s bridge I might have tested the condition of another resident’s mind upon the same point, but unfortunately the experiment did not occur to me. He came along on horseback, and I called his attention to the swallows shooting to and fro over the water, a pretty spectacle anywhere, but doubly so in this swallow-poor country. He manifested no very lively interest in the subject; but he made me a civil answer,--which is perhaps more than a hobby-horsical catechist, who travels up and down the world cross-examining his busy fellow mortals, has any good reason for counting upon in such a case. With so many things to be seen and done in this short life, it is obvious that all men’s tastes cannot run to ornithology. “Yes,” the stranger said, glancing at the swallows, “I expect they have their nests under the bridge.” A civil answer I called it, but it was better than that; indicating, as it did, some acquaintance with the rough-wing’s habits, or a shrewd knack at guessing. But the man knew nothing about a bird that nested in barns.
