ABSTRACT
Mih Tzii argued in favour of his system as follows : Of old, the great Yu drained off the flood of waters, and caused rivers and streams to flow through the nine divisions of the empire and the parts adjacent thereto,-three hundred great rivers, three thousand branches, and streams without number. With his own hands he plied the bucket and dredger, in order to reduce confusion to uniformity,
Make all streams flow to the sea.
