For almost fifteen thousand years centers of mixed Andite culture persisted in the basin of the Tarim River in Sinkiang and to the south in the highland regions of Tibet, where the Andites and Andonites had extensively mingled. The Tarim valley was the easternmost outpost of the true Andite culture. Here they built their settlements and entered into trade relations with the progressive Chinese to the east and with the Andonites to the north. In those days the Tarim region was a fertile land; the rainfall was plentiful. To the east the Gobi was an open grassland where the herders were gradually turning to agriculture. This civilization perished when the rain winds shifted to the southeast, but in its day it rivaled Mesopotamia itself.
