Eight years have now passed since Shaggycoat brought his mate into the beautiful wilderness valley, and they had proceeded to make it habitable, according to the ideas of a beaver.
Wonderful changes have taken place in the alder meadow since then, and one would not know it to be the same spot. It is no more an alder meadow, but a beautiful forest lake stretching away into the distance until it is lost between the foothills, nearly two miles above the dam. On either side, the sparkling waters flow back to the amphitheatre of hills that enfold it and the lake is altogether like a wonderful sparkling jewel set in the emerald surrounding of the foothills.
Each summer, during his wanderings, Shaggycoat has met other wanderers like himself, and many of them have returned with him to his mountain lake. Even the first autumn, when he returned with his amputated paw, a pair of sleek beavers came with him, so there were two beaver lodges in the pond during the second winter instead of one. The dam was also strengthened and broadened during that second autumn until the pond was twice its original size.
The third spring Shaggycoat's own first family of beavers left the lodge to roam during the summer months, and to return in the autumn with mates. This is the arrangement in a well ordered beaver lodge. The children stay with their parents until they are three years of age, so a lodge usually contains the babies, the yearlings and two-year-olds, who allow themselves shelter under the family lodge until their third birthday, when they are shoved out to make room for the babies who have just come. So there is a general nose breaking at this time, and the elders are sent into the world while all the rest are promoted. But I do not imagine that they have to be shoved very hard, for their love of freedom and wild life, and also the mating instinct, is calling to them that third year, and they always obey the call of nature.
It must not be imagined that the little dam originally built on the spot, flows all this broad expanse of country, for, as we have already seen, year by year it has been added to, until now the gorge is blocked by a log and stone structure that would do credit to man, with all his building and engineering skill. It seems to me that the beaver, with his building instinct, and his ingenuity in making his world over to suit his manner of life, more nearly resembles man than any other wild creature.
Each beaver colony is a veritable city, and each lodge contains a large and well ordered family.
The house is always scrupulously clean, and each member of the family has his own bed which he occupies. The front gate is surrounded by a moat, like the castles of old, and the drawbridge is always up.
The beaver is a veritable Venitian, and his city is a real Venice, with its waterway and its islands of solid earth upon which stand the houses of its many citizens. The new dam which is most important to Beaver City, for it holds the water above the entrances of the score or more of houses, is a fine structure about two hundred feet in length, and nine feet in diameter at its base. Into the structure many thousand logs have been rolled, some of them coming from two or three miles up the lake, for timber is not so plentiful near to the dam as it was.
The engineering genius of this huge undertaking was Shaggycoat, who sat upon his broad flat tail and directed his many workmen. Near by, seated upon the top of one of the lodges, a sentinel was always posted while they worked. He warned them of danger, and they gave their whole attention to the work. At the first suspicious sound he would bring his broad tail down upon the water with a resounding slap that could be heard all along the dam, and all through Beaver City, for water is very mobile, and conducts motion or sound easily. At this well-known signal, the workers who, a moment before, might have been lifting and tugging logs or laying on mortar, would disappear as though the lake had opened and swallowed them. This was really just what happened, but the waters did not open; they were always waiting and ready to receive their little water folks.
For a few moments the lake would be as quiet as though there were not a beaver in the whole shimmering expanse, then a brown muzzle, dripping water, would be cautiously thrust up from some shady corner of the dam, and a careful reconnaissance made. When the beaver had made sure that it was a false alarm, he would call the rest and work would go on as before.
