whose progress in navigation, as in other things, has been checked at this early stage, and who remain the nearest visible types of primitive man. But some savages, other than they, did make progress in the matter of locomotion by water, and the next step was the raft, of which the earliest type known is the sanpan, three pieces of buoyant wood tied together. On this construction, which supplied the earliest generic names both in the east and in the west (sanpan, [schedie], _ratis_), a man would stand and paddle and move along upon the water, and assert his power of hand and eye with the weapons with which native ingenuity had already supplied him. In warm climates, where swimming had become a necessity, and the very children from their earliest years had been habituated to the water, the familiarity that breeds contempt of the very danger which at a previous stage acted as a deterrent, would soon encourage attempts to improve, and enlarge, and increase the speed of the rude vessel in common use. These attempts would naturally follow the line of providing the means for conveying in safety other things besides the living freight of the human person. There would also arise the very natural desire to keep things dry, which would spoil if wetted. Hence the enlargement of the raft, and then the protection afforded by platforms raised upon its central surface, or by planks laid edgewise so as to make a defence, a breastwork against the wave. And no doubt by this time the use of the sail for propulsion had become familiar, and man had already prayed his god for 'the breeze that cometh aft, sail-filler, good companion.' But interesting as it would be to trace the effect of the sail upon the construction of vessels and their development, we must leave that pleasant task to those who, in the present series, will treat of the yacht and its prototypes ([hakatoi]). The earliest method of propulsion was with the human hands. In the picture of Ulysses seated on the mast and keel of his shipwrecked vessel, which he had lashed together with the broken backstay made of bullhide, paddling with his hands on either side, Homer, as we have seen, has presented us with the hero of the highest civilisation known to him reduced to the straits of the merest savage; and he has again enforced this idea in his picture of the same hero of many wiles and many counsels devising for himself the means of escape from the island of Calypso, and, not without divine suggestions, constructing for himself, like an ancient Robinson Crusoe, a primitive raft, with certain improvements and additions; a broad raft be it remembered, and not a boat. A boat would mar the conception which presents to us the civilised man driven back to the straits of barbarism by the unique circumstances in which he is placed.
