Beavers build their houses of the same materials as their dams, and of various sizes, according to the number of the inmates. These, however, do not often exceed four or eight old ones, and from six to fourteen young ones. The houses are of a circular form, elevated some feet above the surface of the water; but the entrance is always low down beneath it. They are more rudely constructed than the dams, too. The wood is laid nearly horizontally, and crosswise; the branches, which project inwards, they cut off with their teeth. First there is a layer of wood, and then one of mud and stones; and so they work on till a sufficient height is gained, when the roof, of rough branches, is placed on the top, and plastered down with mud and stones.
Such was the interesting account which Quambo gave us as we walked along.
No event worthy of description occurred during our walk, though it took us some hours to reach the spot for which I was directing our course.
I was not disappointed. As we approached it cautiously, we caught sight of several beavers running about on the banks of the stream, some nibbling away at the trunks of saplings and small trees which they were engaged in felling. Had we fired, we might have killed two or three; but the rest would have disappeared, and we should then have lost the opportunity of observing them. We therefore crept on, concealing ourselves among the thick underwood.
At length I was afraid, should we get closer, that we might make some noise and alarm the animals. I therefore made a sign to my companions to stop; and looking down, we could discern one of the dams I have spoken of carried across the stream from one side to the other, and apparently not quite finished. Though several beavers were running about it, they were not at work; indeed, all their operations are carried on during darkness. Nature, of course, has given them the instinct to work at this time, which saves them the destruction that would otherwise probably overtake them, both from men and beasts.
After watching them for some time, I wished to retire and let them amuse themselves undisturbed; but Quambo took it into his head to give a loud shout, when in an instant the startled creatures scampered off, and dived under the water. Our chance of seeing more of them was gone; they were evidently on the watch for us, for now and then I saw a snout popping up above the surface, to ascertain if we had taken our departure.
We made our way along the banks of the stream for some distance, till we saw before us a broad expanse of water; and we discovered that it was a shallow lake or pond, bordered by reeds, and with numerous dead trees rising up out of the water near its shores. It struck me that this lake had been produced by the beaver-dams; and on our proceeding downwards towards what appeared to be its outlet, we found what had the appearance of being a long bank, of a convex form, stretched directly across the stream. This, on further examination, I had no doubt was the work of beavers. Alders and willows, and other water-loving trees of considerable size, were growing out of it; and digging down to a slight depth, we found that it consisted of lengths of the trunks of young trees, now rapidly decaying and turning into a vegetable mould, thus affording nourishment to all sorts of plants.
Above the surface of the lake were numerous beaver-houses, and after we had concealed ourselves for some time we caught sight of the inhabitants coming forth and swimming about; while one or two knowing old fellows climbed to the roof of their houses, to keep a look-out, as we supposed, and give notice of approaching danger. We might have shot several, but without the dogs we should not have been able to recover them. Indeed, their skins would have been of much less value than those caught in traps. After watching them for some time, then, we agreed that we ought to be on our homeward way, or we should certainly be benighted. Though we had found the path easily enough in daylight, it would be a hard matter to do so in the dark.
“I should very much like to turn trapper,” said Reuben to me as we walked along. “I once heard a good deal about the lives the trappers lead, from a fine old man who stopped at our house one night, on his way to dispose of his packs of skins at one of the fur-traders’ posts.”
“I suspect that it must be a very hard life, and you would soon get tired of it, Reuben,” I answered.
