The most friendly voice in Nature is the song of the brook. Not the wind in the pines, not the voice of the sea, can compare with this for true sociability. These are always somewhat remote, somewhat mystical in our ears, but the song of the brook is cheerfulness itself. Its _bonhomie_ is irresistible. It gradually prevails over any whim and wins us to a sociable and contented mood. Though the world may seem discordant enough, there is always this wholesome note. No two brooks are alike. As the result of the character of the country through which they flow, they impress one as having strongly defined personalities. A creek flowing sluggishly through the alluvial districts of the South is insipid compared to a mountain stream in New England. Your mountain brook is a strong, salient personality which dominates the landscape. It sweeps in bold curves about the base of cliffs, and contracts into a mere mill race cut in the distorted schist and gneiss. Its suggestion is wholly of savage strength, a rude, forceful thing of the wilderness; its song a masterful strain, a triumphant chant of power. Again, there are merry little streams tinkling in the sunlight. In cutting down its channel, the brook may reach a stratum seemingly richer than any above, so that in April its banks become a garden. While scarcely a flower is to be seen on the hillsides, the fertile floor of the ravine is carpeted with spurred violets, groundnut and spring beauties. One such as this falls into a glen over a little precipice, spreading itself out like a fine veil which ceaselessly undulates in the breeze, and now and again floats away in mist ere it can reach the pool below. Under the overhanging rock, Alpine woodsia and cliff-brake thickly cluster, while on narrow shelves are hanging gardens of dicentra, and in the crannies, little patches of mountain saxifrage. Below is a golden sheen where the spicebush is in flower, and a shimmer of pale green about the early willows. From the glen comes the song of the ruby kinglet, bubbling up and dying away. Incomparably wild, it seems to express the abandon of a spirit ever free. All the while the companionable brook gurgles and tinkles its reposeful melody, and the white veil of the waterfall undulates softly in its dark cavern. The air is full of that indescribable suggestion of spring, which is like hashish, and casts a glamor over the world. Gradually one is imbued with a sylvan consciousness and attains to a rapt and intimate point of view.
