The Maine Woods
by Henry D. Thoreau
After reaching the middle of the lake, we found the waves as usual pretty high, and the Indian warned my companion, who was nodding, that he must not allow himself to fall asleep in the canoe lest he should upset us; adding, that when Indians want to sleep in a canoe, they lie down straight on the bottom. But in this crowded one that was impossible. However, he said that he would nudge him if he saw him nodding.
A belt of dead trees stood all around the lake, some far out in the water, with others prostrate behind them, and they made the shore, for the most part, almost inaccessible. This is the effect of the dam at the outlet. Thus the natural sandy or rocky shore, with its green fringe, was concealed and destroyed. We coasted westward along the north side, searching for the outlet, about ¼ of a mile distant from this savage-looking shore, on which the waves were breaking violently, knowing that it might easily be concealed amid this rubbish, or by the over-lapping of the shore. It is remarkable how little these important gates to a lake are blazoned. There is no triumphal arch over the modest inlet or outlet, but at some undistinguished point it trickles in or out through the uninterrupted forest, almost as through a sponge.
We reached the outlet in about an hour, and carried over the dam there, which is quite a solid structure, and about ¼ of a mile farther there was a 2nd dam. The reader will perceive that the result of this particular damming about Chamberlain Lake is, that the head-waters of the St. John are made to flow by Bangor.
They have thus dammed all the larger lakes, raising their broad surfaces many feet; Moosehead, for instance, some 40 miles long, with its steamer on it; thus turning the forces of nature against herself, that they might float their spoils out of the country. They rapidly run out of these immense forests all the finer, and more accessible pine timber, and then leave the bears to watch the decaying dams, not clearing nor cultivating the land, nor making roads, nor building houses, but leaving it a wilderness, as they found it. In many parts, only these dams remain, like deserted beaver-dams. Think how much land they have flowed, without asking Nature's leave! When the State wishes to endow an academy or university, it grants it a tract of forest land: one saw represents an academy; a gang, a university.
The wilderness experiences a sudden rise of all her streams and lakes, she feels 10,000 vermin gnawing at the base of her noblest trees, many combining, drag them off, jarring over the roots of the survivors, and tumble them into the nearest stream, till the fairest having fallen, they scamper off to ransack some new wilderness, and all is still again. It is as when a migrating army of mice girdles a forest of pines. The chopper fells trees from the same motive that the mouse gnaws them, — to get his living. You tell me that he has a more interesting family than the mouse. That is as it happens. He speaks of a "berth" of timber, a good place for him to get into, just as a worm might. When the chopper would praise a pine, he will commonly tell you that the one he cut was so big that a yoke of oxen stood on its stump; as if that were what the pine had grown for, to become the footstool of oxen.
