They cower in the terrible pen, knowing nothing at all about their hides being valued all the way from fifty cents to three dollars, according to the quality; nothing about the dignity of being a coin of the realm in the Northern wilderness, where one beaver-skin sets the value for mink, otter, marten, bear, and all other skins, one pound of tobacco, one kettle, five pounds of shot, a pint of brandy, and half a yard of cloth; nothing about the rascally Indians long ago bartering forty of their hides for a scrap of iron and a great company sending one hundred thousand beaver-skins in a single year to make hats and cloaks for the courtiers of Europe; nothing about the laws of man forbidding the killing of beaver till their number increase. All the little beaver remembers is that it opened its eyes to daylight in the time of soft, green grasses; and that as soon as it got strong enough on a milk diet to travel, the mother led the whole family of kittens--usually three or four--down the slanting doorway of their dim house for a swim; and that she taught them how to nibble the dainty, green shrubs along the bank; and then the entire colony went for the most glorious, pell-mell splash up-stream to fresh ponds. No more sleeping in that stifling lodge; but beds in soft grass like a goose-nest all night, and tumbling in the water all day, diving for the roots of the lily-pads. But the old mother is always on guard, for the wolves and bears are ravenous in spring. Soon the cubs can cut the hardening bark of alder and willow as well as their two-year-old brothers; and the wonderful thing is--if a tooth breaks, it grows into perfect shape inside of a week. By August the little fellows are great swimmers, and the colony begins the descent of the stream for their winter home. If unmolested, the old dam is chosen; but if the hated man-smell is there, new waterways are sought. Burrows and washes and channels and retreats are cleaned out. Trees are cut and a great supply of branches laid up for winter store near the lodge, not a chip of edible bark being wasted. Just before the frost they begin building or repairing the dam. Each night's frost hardens the plastered clay till the conical wattled roof--never more than two feet thick--will support the weight of a moose.
