"Oh wedded Brook! my strength is gone; here must I pause; but you go on. Perhaps before long I shall meet you again. Go slowly; over the meadows and through the villages make me a path; I'll know which way you went." And so they parted; and so the lonely Brook meandered on, and finding out a bubbling spring, was well recruited for the journey. As she went she heard, across a little knoll, a remembered voice, and stopped. "I know you, sister Brook," cried out the voice, "go on a bit and turn towards your left, and there I'll meet you." And towards the left the lonely Brook met her ambitious sister. She was violent no more; but sober and sedate; calm as the evening sky reflected from her face. "I'm the 'ambitious one,'" said she, "ambitious yet, though all my strength has departed. Here on this spot was I caught and fastened up. They darkened my daylight with that smoking monster yonder, and killed my peace of mind with such a horrid din and clang, I've not a morsel of energy left. I'm a factory slave; and so are you, too, for that matter, now! Don't start; it's not my fault--the way that you were going on, you would have brought up in the Pond below, where there is yet another smoking monster; only worse than this of mine. The Pond there is a horrid fellow; poisoning with some horrid purple dye: I've seen him often when I venture near the dam and look below." "Sister, take courage," cried the other Brook. "I'm glad I met you. I'm ambitious too, for I was lately wedded to a glorious fellow, and have been on such a glorious tour: scampering over all the land. He calls himself the 'Mountain-Torrent.' He is now behind a mile or so, and may be down upon us before long, to free us from this distressing imprisonment you speak of." The monster smoked on; and the clanging din about maddened all the air. Huge wheels went racking and rumbling under huge brick walls. And day by day, a minute at a time, some youthful faces, pale and shadowy, looked wistfully upon the landscape below. But little knew the monster, and the clanging din, and racking wheels; and little hoped the shadowy faces of what the Brooklets plotted at the very factory door. CHAPTER IV. _How the Mountain-Torrent freed the Brooks; and their fate._ The frost dropped on the Brooks, and once more blurred the moon and stars, and shut the sunlight out; and starred a thousand jewels on the mill-dam's brow; and sparkled a myriad icicles from the rumbling wheels. Far away into the country it spread a white mantle, and froze into the very heart of all the Ponds and Creeks above. And then the sun came out and shone so brightly; and then the clouds over-covered it, and the rain came pattering down as of the olden time, when first its peltings stung the meadow Brook and tempted her to roam. And higher swelled the Brooks behind their mill-dam prison, and sent more of their life-blood to refresh the poisoned Pond below.
