The beavers had not only intercepted the course of the river by means of their industrious community, but, still further, all the rivulets that ran into it had their courses stopped, so as to transform the surrounding ground into one vast marsh.
One beaver alone was at work, at the moment, on the principal dam; but very shortly five others appeared, carrying pieces of wood, mud, and bushes. They then all together directed their course towards a part of the barrier which, as the lady could perceive, needed repair. They deposited their load on the broken part, and plunged into the water, but only to reappear almost instantly on the surface.
Everyone brought up a certain quantity of slimy mud, which they employed as mortar to join and render firm the pieces of wood and the bushes; they went away and returned again with more wood and mud; in short, this work of masonry was carried on till the breach had entirely disappeared.
As soon as all was in order, the industrious animals enjoyed a moment's recreation; they pursued each other in the pond, plunged to the bottom of the water, or sported on the surface, striking the water noisily with their tails.
Doña Luz beheld this singular spectacle with increasing interest. She could have remained the whole day watching these strange animals.
Whilst the first were amusing themselves thus, two other members of the community appeared. For some time they looked gravely on at the sports of their companions, without showing any inclination to join them; then climbing up the steep bank not far from the spot where the trapper and the young girl were watching, they seated themselves upon their hind paws, leaning the fore ones upon a young pine, and beginning to gnaw the bark of it. Sometimes they detached a small piece, and held it between their paws, still remaining seated; they nibbled it with contortions and grimaces pretty much resembling those of a monkey shelling a walnut.
The evident object of these beavers was to cut down the tree, and they laboured at it earnestly. It was a young pine of about eighteen inches in diameter at the part where they attacked it, as straight as an arrow, and of considerable height. No doubt they would soon have succeeded in cutting it through; but the general, uneasy at the prolonged absence of his niece, made up his mind to go in search of her, and the beavers, terrified at the noise of the horses, dived into the water and disappeared.
The general reproached his niece gently for her long absence; but she, delighted with what she had seen, did not heed him, and promised herself to be frequently an invisible spectator of the proceedings of the beavers.
The little party, under the direction of the trapper, directed their course towards the rancho, in which he had offered them shelter from the burning rays of the sun, which was now at its zenith.
Doña Luz, whose curiosity was excited to the highest pitch by the attractive spectacle at which she had been present, determined to make up for her uncle's unwelcome interruption by asking Black Elk all the particulars of the habits of the beavers, and the manner in which they were caught.
