As time progressed, and men began to display wisdom in making tools of stone and in the moulding of metal, we can imagine that they soon bethought themselves of flattening the surface of their rafts; and then, finding them unwieldy and difficult to manage, no doubt, they hit upon the idea of hollowing out the logs. Adzes were probably not invented at that time, so they betook themselves to the element of fire--which is at the present day used by savage nations for the same purpose--and burned out the insides of their logs. Thus _canoes_ sprang into being. But such canoes were clumsy and heavy, besides being liable to split; men therefore bethought themselves of constructing a light framework of wood, which they covered with bark or skin. Then artificers in iron invented saws; logs were ripped up; planks were formed; pitch oozed ready to hand from the trees; with grass, perchance, they caulked the seams;--and soon the first _boat_ floated on the water--clumsy and tub-like, no doubt, but serviceable withal--and youths of a hundred years old, and full-grown men of two or three hundred, capered and shouted on the shore with delight at the great invention; while venerable patriarchs, of seven or eight hundred summers, gazed in wonder, with almost prophetic solemnity, and exclaimed that they had never before seen the like of _that_ in all the course of their long, long lives! Those times are old now--so old that men can scarcely get their minds to realise how old they are; nevertheless, the craft that were used then are used even now, and that not only among the savages of distant lands, but by men living at our very doors. The _coracle_, a basket-boat of the most primitive description, is still occasionally met with in South Wales. It is neither more nor less than a large wicker basket covered with a hide, and is tub-shaped, and clumsy to a degree. When the Romans invaded Britain, this species of boat was in common use. Like the canoe of the North American Indian, it is easily upset, and we should think must be rather unmanageable; but as we are not likely ever again to be reduced to it in this country, we can afford to regard its faults with indifference. From little boats to big boats there is but a step; and no doubt rivers were soon navigated, and new countries explored, while those who lived near the sea-coast dared even to launch their boats upon the ocean; but they "hugged the shore," undoubtedly, and seldom ventured to proceed at night unless the stars shone brightly in the sky.
