VI. THE BUILDERS.

A curious bit of wild life came to me at dusk one day in the wilderness. It was midwinter, and the snow lay deep. I was sitting alone on a fallen tree, waiting for the moon to rise so that I could follow the faint snowshoe track across a barren, three miles, then through a mile of forest to another trail that led to camp. I had followed a caribou too far that day, and this was the result—feeling along my own track by moonlight, with the thermometer sinking rapidly to the twenty-below-zero point.

There is scarcely any twilight in the woods; in ten minutes it would be quite dark; and I was wishing that I had blankets and an axe, so that I could camp where I was, when a big gray shadow came stealing towards me through the trees. It was a Canada lynx. My fingers gripped the rifle hard, and the right mitten seemed to slip off of itself as I caught the glare of his fierce yellow eyes.

But the eyes were not looking at me at all. Indeed, he had not noticed me. He was stealing along, crouched low in the snow, his ears back, his stub tail twitching nervously, his whole attention fixed tensely on something beyond me out on the barren. I wanted his beautiful skin; but I wanted more to find out what he was after; so I kept still and watched.

At the edge of the barren he crouched under a dwarf spruce, settled himself deeper in the snow by a wriggle or two till his feet were well under him and his balance perfect, and the red fire blazed in his eyes and his big muscles quivered. Then he hurled himself forward—one, two, a dozen mighty bounds through flying snow, and he landed with a screech on the dome of a beaver house. There he jumped about, shaking an imaginary beaver like a fury, and gave another screech that made one's spine tingle. That over, he stood very still, looking off over the beaver roofs that dotted the shore of a little pond there. The blaze died out of his eyes; a different look crept into them. He put his nose down to a tiny hole in the mound, the beavers' ventilator, and took a long sniff, while his whole body seemed to distend with the warm rich odor that poured up into his hungry nostrils. Then he rolled his head sadly, and went away.

Now all that was pure acting. A lynx likes beaver meat better than anything else; and this fellow had caught some of the colony, no doubt, in the well-fed autumn days, as they worked on their dam and houses. Sharp hunger made him remember them as he came through the wood on his nightly hunt after hares. He knew well that the beavers were safe; that months of intense cold had made their two-foot mud walls like granite. But he came, nevertheless, just to pretend he had caught one, and to remember how good his last full meal smelled when he ate it in October.

It was all so boylike, so unexpected there in the heart of the wilderness, that I quite forgot that I wanted the lynx's skin. I was hungry too, and went out for a sniff at the ventilator; and it smelled good. I remembered the time once when I had eaten beaver, and was glad to get it. I walked about among the houses. On every dome there were lynx tracks, old and new, and the prints of a blunt nose in the snow. Evidently he came often to dine on the smell of good dinners. I looked the way he had gone, and began to be sorry for him. But there were the beavers, safe and warm and fearless within two feet of me, listening undoubtedly to the strange steps without. And that was good; for they are the most interesting creatures in all the wilderness.

Most of us know the beaver chiefly in a simile. "Working like a beaver," or "busy as a beaver," is one of those proverbial expressions that people accept without comment or curiosity. It is about one-third true, which is a generous proportion of truth for a proverb. In winter, for five long months at least, he does nothing but sleep and eat and keep warm. "Lazy as a beaver" is then a good figure. And summer time—ah! that's just one long holiday, and the beavers are jolly as grigs, with never a thought of work from morning till night. When the snow is gone, and the streams are clear, and the twitter of bird songs meets the beaver's ear as he rises from the dark passage under water that leads to his house, then he forgets all settled habits and joins in the general heyday of nature. The well built house that sheltered him from storm and cold, and defied even the wolverine to dig its owner out, is deserted for any otter's den or chance hole in the bank where he may sleep away the sunlight in peace. The great dam, upon which he toiled so many nights, is left to the mercy of the freshet or the canoeman's axe; and no plash of falling water through a break—that sound which in autumn or winter brings the beaver like a flash—will trouble his wise little head for a moment.

All the long summer he belongs to the tribe of Ishmael, wandering through lakes and streams wherever fancy leads him. It is as if he were bound to see the world after being cooped up in his narrow quarters all winter. Even the strong family ties, one of the most characteristic and interesting things in beaver life, are for the time loosened. Every family group when it breaks up housekeeping in the spring represents five generations. First, there are the two old beavers, heads of the family and absolute rulers, who first engineered the big dam and houses, and have directed repairs for nobody knows how long. Next in importance are the baby beavers, no bigger than musquashes, with fur like silk velvet, and eyes always wide open at the wonders of the first season out; then the one-and two-year-olds, frisky as boys let loose from school, always in mischief and having to be looked after, and occasionally nipped; then the three-year-olds, who presently leave the group and go their separate happy ways in search of mates. So the long days go by in a kind of careless summer excursion; and when one sometimes finds their camping ground in his own summer roving through the wilderness, he looks upon it with curious sympathy. Fellow campers are they, pitching their tents by sunny lakes and alder-fringed, trout-haunted brooks, always close to Nature's heart, and loving the wild, free life much as he does himself.
