In his second year he revived the government salt monopoly and put the money into his private purse. Heretofore it had been divided between certain monasteries and officials. The Mongol empress made him furnish large quantities of timber from Păk-tu Mountain, floating it down the Yalu. It was used in the building of monasteries. The whole expense was borne by the king. The latter was now spending most of his time in Peking. The Koryŭ officials earnestly desired him to come back to Song-do, but he refused. There was a constant flow of eunuchs and courtesans from Koryŭ to Peking and it would be difficult to imagine a more desperate condition of affairs in the king-deserted country. How it was being governed we do not know. It was probably governing itself. The rural districts, which had been laid waste by the Mongol armies and which had been deserted by their occupants, were probably being gradually occupied again and the less they heard of Song-do the better they liked it. In the third year of his reign the king killed his son because some busybodies told him that the young man was conspiring to drive him from the throne. This shows the depths to which the court had sunk, when kings were not sure but that their own sons were their worst enemies. Orders kept coming from Peking to make certain eunuchs Princes. These orders could not be disregarded. These eunuchs had doubtless been in Peking and were known to be devoted to Mongol interests. All this time the king was in Peking where his presence began to be something of a bore. The mother of the Emperor urged him to go back to Koryŭ. He promised to go in the following autumn, but when the time came he changed his mind and abdicated in favor of his second son. The new king, named To, posthumous title Ch‘ung-suk, came to the throne in 1314. One of his first acts was to take a thorough census of the people. Unfortunately the result is not recorded. The revenue laws were also changed and a new measurement of the fields was ordered with a view to a more effective collection of the revenue. The king likewise had ambitions along religious lines, for he sent 150 pounds of silver to Nanking to purchase books; and 10,800 were secured. The emperor also gave 4,070 volumes. These were doubtless Buddhist books and it is more than likely that many of the books in the Sanscrit or Thibetan character, still found in the monasteries in Korea, are copies of the works introduced into Koryŭ during these times.
