The overthrow of Wou Sankwei and the conquest of Formosa completed what may be called the pacification of China by the Manchus. From that period to the Taeping Rebellion, or for nearly 200 years, there was no internal insurrection on a large scale. On the whole the Manchus stained their conclusive triumph by few excesses, and Kanghi's moderation was scarcely inferior to that of his father, Chuntche. The family of Wou Sankwei seems to have been rooted out more for the personal attempt of the son at Pekin than for the bold ambition of the potentate himself. The family of Koshinga was spared, and its principal representative received the patent of an earl. Thus, by a policy judiciously combined of severity and moderation, did Kanghi make himself supreme, and complete the work of his race. Whatever troubles may have beset the government in the last 220 years, it will be justifiable to speak of the Manchus and the Tatsing dynasty as the legitimate authorities in China, and, instead of foreign adventurers, as the national and recognized rulers of the Middle Kingdom. CHAPTER XI THE EMPEROR KANGHI Among the Mongol tribes the noblest at this period were the Khalkas. They prided themselves on being the descendants of the House of Genghis, the representatives of the special clan of the great conqueror, and the occupants of the original home in the valleys of the Onon and Kerulon. Although their military power was slight, the name of the Khalka princes stood high among the Mongol tribes, and they exercised an influence far in excess of their numbers or capacity as a fighting force. Kanghi determined to establish friendly relations with this clan, and by the dispatch of friendly letters and costly presents lie succeeded in inducing the Khalka chiefs to enter into formal alliance with himself, and to conclude a treaty of amity with China, which, be it noted, they faithfully observed. Kanghi's efforts in this direction, which may have been dictated by apprehension at the movements of his new neighbors, the Russians, were thus crowned with success, and the adhesion of the Khalkas signified that the great majority of the Mongols would thenceforth abstain from acts of unprovoked aggression on the Chinese frontier. But the advance of China and her influence, even in the form of paying homage to the emperor as the Bogdo Khan, or the Celestial Ruler, so far west as the upper course of the Amour, involved the Pekin Government in fresh complications by bringing it into contact with tribes and peoples of whom it had no cognizance. Beyond the Khalkas were the Eleuths, supreme in Ili and Kashgaria, and divided into four hordes, who obeyed as many chiefs. They had had some relations with the Khalkas, but of China they knew nothing more than the greatness of her name. When the surrender of the Khalka princes became known the Eleuth chiefs held a grand assembly or kuriltai, and at this it was finally, and, indeed, ostentatiously, decided not to yield Kanghi his
