CHAPTER XVI.

If a comet is said to have appeared on a certain day in a certain portion of the heavens, a simple astronomical calculation will at once guide the student of Chinese history to the discovery of some important date which may give the required clue to many a disputed point in the science of chronology. Similarly the record of geological upheavals, overflowings of the Yellow River or the Yangtzŭ, and such-like disturbances, places a valuable key in the hands of those who study the land of China from a physical or scientific standpoint.
