 874 their descendants were later driven into India with their Aryan brethren from the regions to the north.

Ten per cent of the Mesopotamians turned eastward in their northern trek, entering Sinkiang, where they blended with the Andite-yellow inhabitants. The majority of the able offspring of this racial union later entered China and contributed much to the immediate improvement of the northern division of the yellow race.

Ten per cent of these fleeing Andites made their way across Arabia and entered Egypt.

Five per cent of the Andites, the very superior culture of the coastal district about the mouths of the Tigris and Euphrates who had kept themselves free from intermarriage with the inferior neighboring tribesmen, refused to leave their homes. This group represented the survival of many superior Nodite and Adamite strains.

The Andites had almost entirely evacuated this region by 6000, though their descendants, largely mixed with the surrounding Sangik races and the Andonites of Asia Minor, were there to give battle to the northern and eastern invaders at a much later date.

The cultural age of the second garden was terminated by the increasing infiltration of the surrounding inferior stocks. Civilization moved westward to the Nile and the Mediterranean islands, where it continued to thrive and advance long after its fountainhead in Mesopotamia had deteriorated. And this unchecked influx of inferior peoples prepared the way for the later conquest of all Mesopotamia by the northern barbarians who drove out the residual strains of ability. Even in later years the cultured residue still resented the presence of these ignorant and uncouth invaders.

The river dwellers were accustomed to rivers overflowing their banks at certain seasons; these periodic floods were annual events in their lives. But new perils threatened the valley of Mesopotamia as a result of progressive geologic changes to the north.

For thousands of years after the submergence of the first Eden the mountains about the eastern coast of the Mediterranean and those to the northwest and northeast of Mesopotamia continued to rise. This elevation of the highlands was greatly accelerated about 5000, and this, together with greatly increased snowfall on the northern mountains, caused unprecedented floods each spring throughout the Euphrates valley. These spring floods grew increasingly worse so that eventually the inhabitants of the river regions were driven to the eastern highlands. For almost a thousand years scores of cities were practically deserted because of these extensive deluges.

Almost five thousand years later, as the Hebrew priests in Babylonian captivity sought to trace the Jewish people back to Adam, they found great difficulty in piecing the story together; and it occurred to one of them to abandon the effort, to let the whole world drown in its wickedness at the time of Noah's flood, and thus to be in a better position to trace Abraham right back to one of the three surviving sons of Noah.
