Down in the valley below my cabin, within a few rods of the spot where the ruins of Kit Carson's cabin still stand, are two small streams along which I early found numerous traces of beaver. At the confluence of these streams were dams and houses that were not entirely deserted; for occasionally the beavers did some repair work. Since they were within five minutes' walk of my cabin I visited them frequently during all seasons of the year. Five times I saw the beavers return to the old home site, repair the dams and rebuild the houses. Four times I saw them forced to desert their home, once because a fire burned the surrounding trees which were their source of food, the other times to elude trappers. I discovered that this colony consisted of a trap-maimed old couple and their annual brood. The male had lost a portion of his right hind foot, his mate had only a stump for her left front one. I early dubbed them Mr. and Mrs. Peg, and came to have a real neighborly affection for them. Their infirmities made it easy for me to keep track of them, and to keep up with their social activities. Neighborly interest must be kept alive by the neighbors' doings, you know! They certainly showed no inclination to become dull from overwork! About the time the ice on their pond began to break up, they would take their youngsters and start upon their summer vacation. Upon a number of occasions I found their familiar tracks along the streams eight or ten miles below their home site; once more than fifteen miles away. On their rambles they met other beaver families, and stopped to visit; the young people of the combined families played and splashed about, while their more sedate elders lay contentedly basking in the sun. But late August or early September always saw Mr. and Mrs. Peg back home; usually without their youngsters. Those precocious paddlers had set up homes for themselves or had wedded into other tribes. The old couple at once set to work, toiling night and day, taking no time off for rest. They repaired their dam to raise the water to the desired level, replastered their house inside and out with mud, and in addition cut down a number of aspen trees, severed their trunks into lengths they could handle, and brought both trunks and limbs down into the pond. They towed the heavy green wood down first and piled it in the deep water near their house, the rest they piled upon these until their larder was full. They ate the whole of the smaller limbs of the aspen, but only the bark of the larger boughs and trunks. They used the wood for house and dam construction.
