Once I found one living all by himself on an island in the middle of a wilderness lake, with no company whatever except a family of mink, who are his enemies. He had probably crossed on the ice in the late spring, and while he was busy here and there with his explorations the ice broke up, cutting off his retreat to the mainland, which was too far away for his swimming. So he was a prisoner for the long summer, and welcomed me gladly to share his exile. He was the only red squirrel I ever met that never scolded me roundly at least once a day. His loneliness had made him quite tame. Most of the time he lived within sight of my tent door. Not even Simmo's axe, though it made him jump twice from the top of a spruce, could keep him long away. He had twenty ways of getting up an excitement, and whenever he barked out in the woods I knew that it was simply to call me to see his discovery,--a new nest, a loon that swam up close, a thieving muskrat, a hawk that rested on a dead stub, the mink family eating my fish heads,--and when I stole out to see what it was, he would run ahead, barking and chuckling at having some one to share his interests with him. In such places squirrels use the ice for occasional journeys to the mainland. Sometimes also, when the waters are calm, they swim over. Hunters have told me that when the breeze is fair they make use of a floating bit of wood, sitting tip straight with tail curled over their backs, making a sail of their bodies--just as an Indian, with no knowledge of sailing whatever, puts a spruce bush in a bow of his canoe and lets the wind do his work for him. That would be the sight of a lifetime, to see Meeko sailing his boat; but I have no doubt whatever that it is true. The only red squirrel that I ever saw in the water fell in by accident. He swam rapidly to a floating board, shook himself, sat up with his tail raised along his back, and began to dry himself. After a little he saw that the slight breeze was setting him farther from shore. He began to chatter excitedly, and changed his position two or three times, evidently trying to catch the wind right. Finding that it was of no use, he plunged in again and swam easily to land. That he lives and thrives in the wilderness, spite of enemies and hunger and winter cold, is a tribute to his wits. He never hibernates, except in severe storms, when for a few days he lies close in his den. Hawks and owls and weasels and martens hunt him continually; yet he more than holds his own in the big woods, which would lose some of their charm if their vast silences were not sometimes broken by his petty scoldings.
