The canoe navies, like other navies, did very well so long as no enemy came with something better. But when boats began to gain ground, canoes began to lose it. We do not know who made the first boat any more than we know who made the first raft or canoe. But the man who laid the first keel was a genius, and no mistake about it; for the keel is still the principal part of every rowboat, sailing ship, and steamer in the world. There is the same sort of difference between any craft that has a keel and one that has not as there is between animals which have backbones and those which have not. By the time boats were first made someone began to find out that by putting a paddle into a notch in the side of the boat and pulling away he could get a stronger stroke than he could with the paddle alone. Then some other genius, thousands of years after the first open boat had been made, thought of making a deck. Once this had been done, the ship, as we know her, had begun her glorious career. But meanwhile sails had been in use for very many thousands of years. Who made the first sail? Nobody knows. But very likely some Asiatic savage hoisted a wild beast's skin on a stick over some very simple sort of raft tens of thousands of years ago. Rafts had, and still have, sails in many countries. Canoes had them too. Boats and ships also had sails in very early times, and of very various kinds: some made of skins, some of woven cloth, some even of wooden slats. But no ancient sail was more than what sailors call a wind-bag now; and they were of no use at all unless the wind was pretty well aft, that is, more or less from behind. We shall presently find out that tacking, (which is sailing against the wind), is a very modern invention; and that, within three centuries of its invention, steamers began to oust sailing craft, as these, in their turn, had ousted rowboats and canoes.
