It might be thought that, as there are trees to be felled both in summer and winter, the beaver, though he does not hibernate, would find no more difficulty in procuring food in the one season than in the other, so that it would not be necessary for him to store up a supply of it, for winter consumption, either in his lodges or at the bottom of his pond. In reality, however, there are difficulties, and “they are compelled,” says Mr. Morgan, “to provide a store of subsistence for the long winters of the north, during which their ponds are frozen over, and the danger of venturing upon the land is so largely increased as to shut them up, for the most part, in their habitations.” Mr. Morgan does not tell us what these dangers are, but no doubt he is referring to various predaceous animals, such as lynxes, pumas, gluttons, and particularly wolves, all of which, by reason of their own difficulties in procuring food, become more ravenous in the winter, and would, no doubt, hail a beaver, away from his lodge, with delight, and hasten to supply his temporary want, with an interior chamber of their own. “In preparing for the winter,” Mr. Morgan continues, “their greatest efforts in tree-cutting are made. They commence in the latter part of September, and continue through October and into November the several employments of cutting and storing their winter food and of repairing their lodges and dams. Part of this winter supply the beaver, as we have seen, brings into his dwelling, and for this purpose he makes a special entrance to it, which facilitates his doing so. Beaver-lodges are always situated on the edge of the water, and it is by diving under water that the beaver goes in and out of them. The lodge enters the water at one point, and, within the space conterminous with it, there are two or more entrances, which open out beneath its surface at a sufficient depth for the water not to be frozen during the winter; since, if this were the case, the inmates would perish, the walls being, at this time, too hard and solid even for a beaver’s teeth. These entrances are made,” says Mr. Morgan, “with great skill and in the most artistic manner. In new lodges there is generally but one, but others are added, with their increase in size, under the process of repairing, until in large lodges there are sometimes three or four. These entrances are of two kinds, one straight and the other sinuous. The first we shall call ‘the wood entrance,’ from the beavers’ evident design to facilitate the admission into their chamber of the wood-cuttings upon which they subsist, during the season of winter. These cuttings are of such size and length that such an entrance is absolutely necessary for their free admission into the lodge. The other, which we shall call ‘the beaver entrance’” (not a very good name, I think, as the wood does not enter by itself) “is the ordinary one for the exit and return of the animal.” As far as I can understand from reading Mr.
