"When you and I behind the veil are past, Oh but the long long while the world shall last." The next summer, 1893, the Moraine site was resettled. During the first season the colonists put in their time repairing dams and were content to live in holes. In autumn they gathered no harvest, and no trace of them could be found after the snow; so it is likely that they had returned to winter in the colony whence they had come. But early in the next spring there were reinforced numbers of them at work establishing a permanent settlement. Three dams were repaired, and in the autumn many of the golden leaves that fell found lodgment in the fresh plaster of two new houses. Most beaver dams are built on the installment plan,--are the result of growth. As the pond fills with sediment, and the water becomes shallower, the dam is built higher and, where conditions require it, longer; or, as is often the case, it may be raised and lengthened for the purpose of raising or backing water to the trees that are next to be harvested. The dams are made of sticks, small trees, sods, mud, stones, coal, grass, roots,--that is, combinations of these. The same may be said of the houses. For either house or dam the most convenient material is likely to be used. But this is not always the case; for the situation of the house, or what the dam may have to endure, evidently is sometimes considered, and apparently that kind of material is used that will best meet all the requirements. Most beaver dams are so situated that they are destined earlier or later to accumulate sediment, trash, and fallen leaves, and become earthy; then they will, of course, be planted by Nature with grass, shrubby willows, and even trees. I have seen many trees with birds' nests in them standing on a beaver dam; yet the original dam had been composed almost entirely of sticks or stones. Why do beavers want or need ponds? They have very heavy bodies and extremely short legs. On land they are slow and awkward and in the greatest danger from their enemies,--wolves, lions, bears, and wildcats; but they are excellent swimmers, and in water they easily elude their enemies, and through it they conveniently bring their harvests home. Water is necessary for their existence, and to have this at all times compels the construction of dams and ponds.
