The middle Tigris basin seems to have received a large influx of Semites of the Canaanitic wave at least as early as Babylonia, and thanks to various causes-to the absence of a prior local civilization as advanced as the sumerian, to greater distance from such enterprising fomenters of disturbance as Elam and Arabia, and to a more invigorating climate-these Semites settled down more quickly and thoroughly into an agricultural society than the Babylonians and developed it in greater purity.
