found necessary, as we have seen, to teach the Wu folk the use of war-chariots and bows and arrows: this important statement points distinctly to the previous utter isolation of Wu from the pale of Chinese civilization. In the year 502 Ts'i sent a princess as hostage to Wu, and ended by giving her in marriage to the Wu heir: (we have seen how Tsin anticipated Ts'i by twenty-five years in conferring a similar honour upon Ts'u). A century or more later, when Mencius was advising the bellicose court of Ts'i, he alluded with indignation to this "barbarous" act. In 544 the Wu prince Ki-chah had visited Lu and other orthodox states. [Illustration: Map of the Hwai system and Valley 1. The two lines indicated by...............to the north are (1) the River Sz (now Grand Canal), from Confucius' birthplace, and (2) the River I (from modern I-shui city south of the German colony). After receiving the I, the Sz entered the Hwai as it emerged from Lake Hung-t&h; but this Hwai mouth no longer exists; the waters are dissipated in canals. The Wu fleets coasting up to the Hwai, were thus able to creep into the heart of Shan Tung province, east and west. 2. The Yang-tsz had three branches: (1) northern, much as now; (2) middle, branching at modern Wuhu, crossing the T'ai-hu Lake, and following the Soochow Creek and Wusung River past Shanghai; (3) southern, carrying part of the Tai-hu waters by a forgotten route (probably the modern Grand Canal), to near Hangchow. 3. The three crosses [Image: Circle with an 'X' in it] mark the capitals of Wu (respectively near Wu-sih and Soochow) and Yiieh (near Shao-hing). The modern canal from Hangchow to Shan Tung is clearly indicated. Orthodox China knew absolutely nothing of Cheh Kiang, Fuh Kien, or Kiang Si provinces south of lat. 300.]
