Sawdust is not so bad to sleep on when you have a boat or a rubber-blanket under you, but it retains moisture badly, and is seldom dry more than an inch below the surface. Moreover, the dry part catches fire and burns in an exceedingly persistent and stealthy manner, tunneling unsuspected in all directions and making itself very disagreeable. The members of the expedition, however, knew its nature and provided against its vagaries by wetting thoroughly in the vicinity of the fire, where the Cook speedily had coffee and a tempting pan of scrambled eggs ready for the evening meal. The voyagers went to sleep this night with unwonted noises in their ears, namely the close-at-hand roar of rapids rising and falling as the mysterious and imperceptible changes of the evening air bore it, now heavily, now faintly, through the thick forest of spruce. It was a wilder region than that through which they had been passing on the lake and its outlet, and the woods gave out sounds at night which often aroused one and another with the pleasing and yet uncomfortable thought of bears and lynxes in his half awakened brain. XIII. SWIFT WATER. Here, at the foot of "Rapid No. 2," the authors would say a word for the benefit of the inexperienced. They are asked by cautious readers if this kind of play is not dangerous. Certainly, just as coasting, and travelling by rail, and crossing Broadway, and playing base and foot-ball, are dangerous. In short, just exactly as life itself is dangerous. They would not advise any but bold swimmers to undertake the amusement; but where proper survey is taken to avoid possible falls, a wetting is the worst that can ordinarily happen. During the entire trip no mishaps occurred save those which came in as part of the fun, and although the voyagers were wet and dry half a dozen times a day, not one caught the slightest cold, or suffered any ill effects from exposure. Hardly any woman, and not by any means all men, can be expected to appreciate the fun of these duckings and other uncertainties of canoe cruising. It may as well be admitted, however, that no out-of-door recreation that is worthy the name, is wholly without risk. The steadiest horses sometimes take fright and run away. Without its rivalries and possible perils to heart and hand, croquet itself would be but an insipid pastime. All excitement presupposes risk of some kind, but it refreshes body and brain alike when taken in reasonable doses and in a fashion that does not infringe on the rights of others. Since the Saturday afternoons of their boyhood the authors have experienced nothing so delightful as those long days on lake and river.
