Moosehead also provides vessels far dearer to the heart of the adventurous than anything driven by steam. Here, mayhap, will an untravelled traveller make his first acquaintance with the birch-bark canoe, and learn to call it by the affectionate diminutive, "Birch." Earlier in life there was no love lost between him and whatever bore that name. Even now, if the untravelled one's first acquaintance be not distinguished by an unlovely ducking, so much the worse. The ducking must come. Caution must be learnt by catastrophe. No one can ever know how unstable a thing is a birch canoe, unless he has felt it slide away from under his misplaced feet. Novices should take nude practice in empty birches, lest they spill themselves and the load of full ones,--a wondrous easy thing to do. A birch canoe is the right thing in the right place. Maine's rivers are violently impulsive and spasmodic in their running. Sometimes you have a foamy rapid, sometimes a broad shoal, sometimes a barricade of boulders with gleams of white water springing through or leaping over its rocks. Your boat for voyaging here must be stout enough to buffet the rapid, light enough to skim the shallow, agile enough to vault over, or lithe enough to slip through, the barricade. Besides, sometimes the barricade becomes a compact wall,--a baffler, unless boat and boatmen can circumvent it,--unless the nautical carriage can itself be carried about the obstacle,--can be picked up, shouldered, and made off with. A birch meets all these demands. It lies, light as a leaf, on whirlpooling surfaces. A tip of the paddle can turn it into the eddy beside the breaker. A check of the setting-pole can hold it steadfast on the brink of wreck. Where there is water enough to varnish the pebbles, there it will glide. A birch thirty feet long, big enough for a trio and their traps, weighs only seventy-five pounds. When the rapid passes into a cataract, when the wall of rock across the stream is impregnable in front, it can be taken in the flank by an amphibious birch. The navigator lifts his canoe out of water, and bonnets himself with it. He wears it on head and shoulders, around the impassable spot. Below the rough water, he gets into his elongated chapeau and floats away. Without such vessel, agile, elastic, imponderable, and transmutable, Androscoggin, Kennebec, and Penobscot would be no thoro'fares for human beings. Musquash might dabble, chips might drift, logs might turn somersets along their lonely currents; but never voyager, gentle or bold, could speed through brilliant perils, gladdening the wilderness with shout and song.
