Years rolled on, and dwellers on the sea-coast became more and more venturous in their voyages along the shore. It behoved them to have larger boats, or barges, with numerous rowers, who would naturally carry weapons with them to guard themselves from foes. War-galleys sprang into being. Strong winds sometimes carried these off-shore, and out of sight of land. Ah, reader! who can conceive the feelings of the first mariners who saw the solid land sink on the horizon, and beheld nothing substantial in all the waste of waters, save their own tiny bark that reeled beneath them on the heaving billows? Perchance these first adventurers on the deep found their way back to land, and afterwards tried the bold experiment of steering by the stars. Perhaps not; but at length it did come about that ships were built, and men were found bold enough to put to sea in them for days and weeks together. The ark is the first ship of which we have any authentic account. We now leave the region of conjecture; for the ark was built by Noah under the immediate direction of the Almighty, and we have a minute account of it in the Bible. More than two thousand three hundred years before our Lord and Saviour Jesus Christ came to earth, man's wickedness had attained to such a height that God resolved to destroy the inhabitants of the world by a deluge. But, in the midst of wrath, God remembered mercy. He spared Noah and his family, and saved them from destruction by placing them in the ark along with pairs of the lower animals. Every reader of the Bible knows the story of the deluge; but everyone may not be aware that traditions of this deluge are found in every part of the earth. East, west, north, and south--civilised and savage--all men tell us of a great flood which once covered the world, and from which only one family was saved, in a boat, or a canoe, or an ark. What the barbarous and savage nations know dimly from tradition, we know certainly and fully from the inspired Word of God. The ark was built; the flood came; Noah with his family and two of every living creature entered into it; and for months the first ship floated on a sea whose shoreless waves flowed round and round the world. What the ark's form was we cannot precisely tell; but we know its dimensions pretty accurately.
