4. Until quite recent times, the true source of the Yang-tsz had been unknown to the Chinese, and the River Min has been, and even still is, considered to be the chief head-water. It flows through the rich country of ancient Shuh, now the administrative centre of Sz Ch'wan province.

5. Even now the Yang-tsz River is practically the only great route from China into Sz Ch'wan, and in ancient times the rapids were probably not negotiable by large craft.

6. The land routes into Sz Ch'wan from the head-waters of the Wei and Ilan Rivers are all extremely precipitous. It was not until 200 B.C. that any military road was attempted.

7. Ancient China meant the Yellow River. Then the Han and the Hwai. Next the Yang-tsz. Last the Sz Ch'wan tributaries of the Yang-tsz. It was through the lakes and rivers south of the Yang- tsz that China at last colonized the south.

CHAPTER I

OPENING SCENES

The year 842 B.C. may be considered the first accurate date in Chinese history, and in this year the Emperor had to flee from his capital on account of popular dissatisfaction with his tyrannical ways: he betook himself northward to an outlying settlement on the Tartar frontier, and the charge of imperial affairs was taken over by a regency or duumvirate.

At this time the confederation of cultured princes called China-- or, to use their own term, the Central Kingdom--was a very different region from the huge mass of territory familiar to us under those names at the present day. It is hardly an exaggeration to say that civilized China, even at that comparatively advanced period, consisted of little more than the modern province of Ho Nan. All outside this flat and comparatively riverless region inhabited by the "orthodox" was more or less barbaric, and such civilization as it possessed was entirely the work of Chinese colonists, adventurers, or grantees of fiefs _in partibus infidelium_ (so to speak). Into matters of still earlier ancient history we may enter more deeply in another chapter, but for the present we simply take China as it was when definite chronology begins.

The third of the great dynasties which had ruled over this limited China had, in 842 B.C., already been on the imperial throne for practically three hundred years, and, following the custom of its predecessors, it had parcelled out all the land under its sway to vassal princes who were, subject to the general imperial law and custom, or ritual, together with the homage and tribute duty prescribed thereunder, all practically absolute in their own domains. Roughly speaking, those smaller fiefs may be said to have corresponded in size with the walled-city and surrounding district of our own times, so well known under the name of _hien_. About a dozen of the larger fiefs had been originally granted to the blood relations of the dynastic founder in or after 1122 B.C.; but not exclusively so, for it seems to have been a point of honour, or of religious scruple, not to "cut off the sacrifices" from ruined or disgraced reigning families, unless the attendant circumstances were very gross; and so it came to pass that successive dynasties would strain a point in order to keep up the spiritual memory of decayed or rival houses.
