Whatever the robin meant, however, and no doubt there was some good reason for his conduct, he had given my curiosity the needed jog. Now, at last, I would do what I had often dreamed of doing,—learn something about the birds of my own region, and be able to recognize at least the more common ones when I saw them.

The interest of the study proved to be the greater for my ignorance, which, to speak within bounds, was nothing short of wonderful; perhaps I might appropriately use a more fashionable word, and call it phenomenal. All my life long I had had a kind of passion for being out-of-doors; and, to tell the truth, I had been so often seen wandering by myself in out-of-the-way wood-paths, or sitting idly about on stone walls in lonesome pastures, that some of my Philistine townsmen had most likely come to look upon me as no better than a vagabond. Yet I was not a vagabond, for all that. I liked work, perhaps, as well as the generality of people. But I was unfortunate in this respect: while I enjoyed in-door work, I hated to be in the house; and, on the other hand, while I enjoyed being out-of-doors, I hated all manner of out-door employment. I was not lazy, but I possessed—well, let us call it the true aboriginal temperament; though I fear that this distinction will be found too subtile, even for the well-educated, unless, along with their education, they have a certain sympathetic bias, which, after all, is the main thing to be depended on in such nice psychological discriminations.

With all my rovings in wood and field, however, I knew nothing of any open-air study. Study was a thing of books. At school we were never taught to look elsewhere for knowledge. Reading and spelling, geography and grammar, arithmetic and algebra, geometry and trigonometry,—these were studied, of course, as also were Latin and Greek. But none of our lessons took us out of the school-room, unless it was astronomy, the study of which I had nearly forgotten; and that we pursued in the night-time, when birds and plants were as though they were not. I cannot recollect that any one of my teachers ever called my attention to a natural object. It seems incredible, but, so far as my memory serves, I was never in the habit of observing the return of the birds in the spring or their departure in the autumn; except, to be sure, that the semi-annual flight of the ducks and geese was always a pleasant excitement, more especially because there were several lakes (invariably spoken of as ponds) in our vicinity, on the borders of which the village "gunners" built pine-branch booths in the season.

But now, as I have said, my ignorance was converted all at once into a kind of blessing; for no sooner had I begun to read bird books, and consult a cabinet of mounted specimens, than every turn out-of-doors became full of all manner of delightful surprises. Could it be that what I now beheld with so much wonder was only the same as had been going on year after year in these my own familiar lanes and woods? Truly the human eye is nothing more than a window, of no use unless the man looks out of it.

Some of the experiences of that period seem ludicrous enough in the retrospect. Only two or three days after my eyes were first opened I was out with a friend in search of wild-flowers (I was piloting him to a favorite station for Viola pubescens), when I saw a most elegant little creature, mainly black and white, but with brilliant orange markings. He was darting hither and thither among the branches of some low trees, while I stared at him in amazement, calling on my comrade, who was as ignorant as myself, but less excited, to behold the prodigy. Half trembling lest the bird should prove to be some straggler from the tropics, the like of which would not be found in the cabinet before mentioned, I went thither that very evening. Alas, my silly fears! there stood the little beauty's exact counterpart, labeled Setophaga ruticilla, the American redstart,—a bird which the manual assured me was very common in my neighborhood.

But it was not my eyes only that were opened, my ears also were touched. It was as if all the birds had heretofore been silent, and now, under some sudden impulse, had broken out in universal concert. What a glorious chorus it was; and every voice a stranger! For a week or more I was puzzled by a song which I heard without fail whenever I went into the woods, but the author of which I could never set eyes on,—a song so exceptionally loud and shrill, and marked by such a vehement crescendo, that, even to my new-found ears, it stood out from the general medley a thing by itself. Many times I struck into the woods in the direction whence it came, but without getting so much as a flying glimpse of the musician. Very mysterious, surely! Finally, by accident I believe, I caught the fellow in the very act of singing, as he stood on a dead pine-limb; and a few minutes later he was on the ground, walking about (not hopping) with the primmest possible gait,—a small olive-brown bird, with an orange crown and a speckled breast. Then I knew him for the golden-crowned thrush; but it was not for some time after this that I heard his famous evening song, and it was longer still before I found his curious roofed nest.

"Happy those early days," those days of childish innocence,—though I was a man grown,—when every bird seemed newly created, and even the redstart and the wood wagtail were like rarities from the ends of the earth. Verily, my case was like unto Adam's, when every fowl of the air was brought before him for a name.

One evening, on my way back to the city after an afternoon ramble, I stopped just at dusk in a grove of hemlocks, and soon out of the tree-top overhead came a song,—a brief strain of about six notes, in a musical but rather rough voice, and in exquisite accord with the quiet solemnity of the hour. Again and again the sounds fell on my ear, and as often I endeavored to obtain a view of the singer; but he was in the thick of the upper branches, and I looked for him in vain. How delicious the music was! a perfect lullaby, drowsy and restful; like the benediction of the wood on the spirit of a tired city-dweller. I blessed the unknown songster in return; and even now I have a feeling that the peculiar enjoyment which the song of the black-throated green warbler never fails to afford me may perhaps be due in some measure to its association with that twilight hour.

To this same hemlock grove I was in the habit, in those days, of going now and then to listen to the evening hymn of the veery, or Wilson thrush. Here, if nowhere else, might be heard music fit to be called sacred. Nor did it seem a disadvantage, but rather the contrary, when, as sometimes happened, I was compelled to take my seat in the edge of the wood, and wait quietly, in the gathering darkness, for vespers to begin. The veery's mood is not so lofty as the hermit's, nor is his music to be compared for brilliancy and fullness with that of the wood thrush; but, more than any other bird-song known to me, the veery's has, if I may say so, the accent of sanctity. Nothing is here of self-consciousness; nothing of earthly pride or passion. If we chance to overhear it and laud the singer, that is our affair. Simple-hearted worshiper that he is, he has never dreamed of winning praise for himself by the excellent manner in which he praises his Creator,—an absence of thrift, which is very becoming in thrushes, though, I suppose, it is hardly to be looked for in human choirs.

And yet, for all the unstudied ease and simplicity of the veery's strain, he is a great master of technique. In his own artless way he does what I have never heard any other bird attempt: he gives to his melody all the force of harmony. How this unique and curious effect, this vocal double-stopping, as a violinist might term it, is produced, is not certainly known; but it would seem that it must be by an arpeggio, struck with such consummate quickness and precision that the ear is unable to follow it, and is conscious of nothing but the resultant chord. At any rate, the thing itself is indisputable, and has often been commented on.
