Beavers Build Houses

"Beavers build houses; but they build them in nowise differently, or better now, than they did, five thousand years ago. Ants, and honey-bees, provide food for winter; but just in the same way they did, when Solomon referred the sluggard to them as patterns of prudence. Man is not the only animal who labors; but he is the only one who improves his workmanship." [Abraham Lincoln]
