When I spoke just now of the worm-eating warbler’s song as almost the only new one heard in Virginia, I ought perhaps to have guarded my words. I meant to say that the worm-eater was almost the only species that I there heard sing for the first time,--a somewhat different matter; for new songs, happily,--songs new to the individual listener,--are by no means so infrequent as the songs of new birds. On the very forenoon of which I am now writing, I heard another strain that was every whit as novel to my ear as the worm-eater’s,--as novel, indeed, as if it had been the work of some bird from the other side of the planet. Again and again it was given out, at tantalizing intervals, and I could not so much as guess at the identity of the singer; partly, it may be, because of the feverish anxiety I was in lest he should get away from me in that endless mountain-side forest. Every repetition I thought would be the last, and the bird gone forever. Finally, as I edged nearer and nearer, half a step at once, with infinite precaution, I caught a glimpse of a chickadee. A chickadee! Could he be doing that? Yes; for I watched him, and saw it done. And these were the notes, or the best that my pencil could make of them: _twee, twee, twee_ (very quick), _twitty, twitty_,--the first measure in a thin, wire-drawn tone, the second a full, clear whistle. Sometimes the three _twees_ were slurred almost into one. Altogether, the effect was most singular. I had never heard anything in the least resembling it, familiar as I had thought myself for some years with the normal four-syllabled song of _Parus carolinensis_. For the moment I was half disposed to be angry,--so much excitement, and so absurd an outcome; but on the whole it is very good fun to be fooled in this way by a bird who happens to have invented a tune of his own. Besides, we are all believers in originality,--are we not?--whatever our own practice. Human travelers were infrequent enough to be little more than a welcome diversion: two young men on horseback; a solitary foot-passenger, who kindly pointed out a trail by which a long elbow in the road could be saved on the descent; and, near the top of the mountain, a four-horse cart, the driver of which was riding one of the wheel-horses. At the summit I chose a seat (not the first one of the jaunt, by any means) and surveyed the valley beyond. It lay directly at my feet, the mountain dropping to it almost at a bound, and the stunted budding trees offered the least possible obstruction to the view. Narrow as the valley was, there was nothing else to be seen in that direction. Immediately behind it dense clouds hung so low that from my altitude there was no looking under them. In one respect it was better so, as sometimes, for the undistracted enjoyment of it, a single painting is better than a gallery.
