(1) The common one that it was universal not merely as regards the human race, but with respect to the world, every part of which, the highest peak Himalayas not peak of the excepted, was submerged. (2) That while drowning all mankind except the eight persons in the ark, it was partial, being limited to central Asia. The ordinary mind will consider ths view abs absurd, and say that the water standing high in Central Asia would run over the world, becoming shallower as it went; but the geologist knows that in such a vast flood what appears to the eye the rising of the waters sinking of the land. If the land subsided is really the in central Asia, cracks Caspian, the Persian Gulf, etc., a deluge extending to the would be produced, while a like upheaval of the land would bring it to a termination.

the great flood that prevailed in the days of Noah. The wickedness of man; the piety of Noah; the building of the ark; the breaking up of the fountains of the ark; the breaking up of the fountains of the deep, and the opening of the windows of heaven; the rain of forty days and forty nights; the preservation of beast and fowl and creeping thing; the prevalence of water on the face of the earth; the resting of the ark on Mount Ararat; and the sending forth of the raven and the dove, are told in chapters vi, vii, and viii of Genesis. A former opinion, that the deluge of Noah was universal, has given way to the view that it was local. Similar traditions are preserved by many peoples. The most notable is that of the Chaldeans, a people akin to the Hebrews. It was found inscribed in cuneiform characters on clay tablets, and was made known in 1872. The Chaldean deluge reached its height in seven days. The ark rested on a mountain in eastern Kurdistan; the Noah-like hero of the Chaldean flood sent forth a raven, a swallow, and a dove.
