In the new Moraine Colony one of the houses was torn to pieces by some animal, probably a bear. This was before Thanksgiving. About midwinter a prospector left his tunnel a few miles away, came to the colony, and dynamited a house, and "got seven of them." Next year two houses were built on the ruins of the two just fallen. That year's harvest-home was broken by deadly attacks of enemies. In gathering the harvest the beavers showed a preference for some aspens that were growing in a moist place about one hundred feet from the water. Whether it was the size of these or their peculiar flavor that determined their election in preference to nearer ones, I could not determine. One day, while several beavers were cutting here, they were surprised by a mountain lion, which leaped upon and killed one of the harvesters. The next day the lion surprised and killed another. Two or three days later a coyote killed one on the same blood-stained spot, and then overtook and killed two others as they fled for the water. I could not see these deadly attacks from the boulder-pile, but in each case the sight of flying beavers sent me rushing upon the scene, where I beheld the cause of their desperate retreat. But despite dangers they persisted until the last of these aspens was harvested. During the winter the bark was eaten from these, and the next season their clean wood was used in the walls of a new house. One spring I several times visited a number of colonies while trying to determine the number of young brought forth at a birth. Six furry little fellows sunning themselves on top of their rude home were the first discovery; this was the twelfth of May. By the close of the month I had come in sight of many youngsters, and found the average number to be five. One mother proudly exhibited eight, while another, one who all winter had been harassed by trappers and who lived in a burrow on the bank, could display but one. In the Moraine Colony the three sets of youngsters numbered two, three, and five. Great times these had as they were growing up. They played over the house, and such fun they had nosing and pushing each other off a large boulder into the water! A thousand merry ripples they sent to the shore as they raced, wrestled, and dived in the pond, both in the sunshine and in the shadows of the willows along the shore.
