To begin with, let us see what the expedition purports to be. In the first place, the thieves used as torches, or otherwise destroyed, the first few pages of the bamboo sheaf book, and we do not know, consequently, whence the Emperor started: there is much indirect evidence, however, to show that he started from some place on the headwaters of the Han River, in what must then have been his own territory (South Shen Si); especially as his three expeditions all ended there. It is certain, however, that he had not travelled many days on his first journey before he reached a tribe of Tartars very frequently mentioned in all histories, and bearing the same name as the Tartars whom Sz-ma Ts'ien says the Emperor Muh _did_ conquer. He crossed the Yellow River on the 169th day, came to two rivers, the Redwater (222nd day), and the Blackwater (248th day), which rivers in after ages have been frequently mentioned in connection with Tibetan, Turkish, and Ouigour wars, and are apparently in the Si-ning and Kan-chou Fu, or possibly Kwa Chou regions (_cf_. p. 68); but first he passed, after the 170th day, a place called "Piled Stones," a name which has never been lost to history, and which corresponds to Nien-po, between Lan-thou Fu and Si-ning, as marked on modern maps. In other words, he went by the only high-road there was in existence, and ever since then has continued in existence (just traversed by Bruce), leading to the Lob Nor region; whence again he branched off, presumably to Turfan, or to Harashar; thence to Urumtsi, and possibly Kuché, as they are respectively now called; but on the whole it is not likely that he got beyond Harashar and Urumtsi. Even 800 years later, when the Chinese had thoroughly explored all the west up to the Hindu Kush, their expeditions had all to proceed from Lob Nor to Khoten, or from Lob Nor (or near it) _viâ_ Harashar and Kuché along the Tarim Valley: it was not for long after the discovery of these routes that the later Chinese discovered the northerly Hami route, and the possibility of avoiding Lob Nor altogether. His charioteer is said in this account to have been a man (named) whose name is exactly the name, written in exactly the same way, as the name of the ancestor of Ts'in, who, Sz-ma Ts'ien tells us, actually was the charioteer of the Emperor when he marched forth against the Tartars, and who hurried back to China when the revolts broke out owing to the Emperor's absence. As the Emperor received, from various princes, presents of wine, silk, and rice, it is almost certain that he must have avoided bleak, out-of-the-way places, and have made for the productive regions of Harashar, Turfan, and possibly Kuché, any or all three of these. With a little more care and patience we may yet succeed in identifying, and by the same names, several more of the places mentioned by the old chronicler. In about ten months (286 days from the first day already mentioned, and 17 days out from "Piled Stones") he reached _Siwangmu_.
