The princes persisted, however, in refusing. Berkai, after waiting a year, asked for orders from Batu, who commanded to install Mangu without further discussion, declaring that those who made trouble would pay with their lives for so doing. The princes descended from Juchi and Tului, with the nephews of Jinghis, met at Koitun Ola, the place designated, and made a last effort to bring the heads of the houses of Ogotai and Jagatai to share in the meeting. An officer sent to Ogul Gaimish, and another to Yissu, son of Jagatai, announced that the other princes had assembled, and were waiting. Khodja and Nagu, seeing that opposition was fruitless, gave a promise to come, and fixed the date of arrival. The term passed, but they came not. An order was given to astrologers to name the day and the hour for installation. The installation took place July, 1251, with the ceremonies which were usual and proper. When the princes inside the Imperial pavilion put their girdles on their shoulders and prostrated themselves nine times before Mangu, their example was followed by ten thousand warriors ranged round the tent on the outside. The Grand Khan commanded that no man should work on that day, that all should forget every quarrel and yield themselves up to rejoicing. He wished to make Nature participate in the festival, and enjoined that no man was to sit on a horse, or put a burden on anything living. No person was to kill an animal, hunt, fish, wound the earth by digging, or otherwise, or trouble the calm of the waters, or their purity. On the morrow a rich feast was given by Mangu in a tent of rare stuffs and great splendor. At his right sat the princes descended from Jinghis, at his left the princesses. A similar feast was given each day for seven days in succession. Each day every guest wore a dress of new color; each day three hundred horses and bullocks with five thousand sheep were eaten, while two thousand cart loads of wine and kumis were drunk to drive away thirst and console the great company.
