Some persons, I hear, had strange experiences. I am told of one man who picked a black-throated blue warbler from a bush, as he might have picked a berry. I myself noted in New Hampshire, what many noted hereabouts, the continual presence of warblers on the ground. ’Tis an ill wind that blows nobody good, and our multitude of young bird students--for, thank Heaven, they _are_ a multitude--had the opportunity of many years to make new acquaintances. A warbler in the grass is a comparatively easy subject. After all, the beginners have the best of it. No knowledge is so interesting as new knowledge. It may be plentifully mixed with ignorance and error. Much of it may need to be unlearned. Young people living about me began to find scarlet tanagers early in April; one boy or girl has seen a scissor-tailed flycatcher, and orchard orioles seem to be fairly common; but at least new knowledge has the charm of freshness. And what a charm that is!--a morning rose, with the dew on it. The old hand may almost envy the raw recruit--the young woman or the boy, to whom the sight of a rose-breasted grosbeak, for instance, is like the sight of an angel from heaven, so strange, so new-created, so incredibly bright and handsome. I love to come upon a group or a pair of such enthusiasts at work in the field, as I not seldom do; all eyes fastened upon a bush or a branch, one eager, low voice trying to make the rest of the company see some wonderful object of which the lucky speaker has caught sight. “There, it has moved to that lower limb! Right through there! Don’t you see it? Oh, what a beauty!” I was down by the river the other afternoon. Many canoes were out, and presently I came to an empty one drawn up against the bank. A few steps more and I saw, kneeling behind a clump of shrubbery, a young man and a young woman, each with an opera-glass, and the lady with an open notebook. “It’s a redstart, isn’t it?” I heard one of them say. It was too bad to disturb them, but I hope they forgave a sympathetic elderly stranger, who, after starting toward them and then sidling off, finally approached near enough to suggest, with a word of apology, that perhaps they would like to see a pretty bunch of water thrushes just across the way, about the edges of the pool under yonder big willow. They seemed grateful, however they may have felt. “Water thrushes!” the young lady exclaimed, and with hasty “Thank you’s,” very politely expressed, they started in the direction indicated. It is to be hoped that they found also the furtive swamp sparrow, of whose presence the bashful intruder, in the perturbation of his spirits, forgot to inform them. If they did find it, however, they were sharp-eyed, or were playing in good luck.
