Many Chinese had settled on Sin Island off Eui-ju but the Koreans on the adjacent mainland resented it. They collected a considerable band of men and crossed to the island where they burned all the houses of the settlers and destroyed all their property. When the king heard of it he condemned it as a brutal outrage. This year was marked by one of the most destructive scourges that ever visited the country. Cholera swept the land from end to end. It is asserted that 370,979 people perished, among whom was the infant Crown Prince. The government found it necessary to undertake the work of interment. The king gave out from the dispensary 29,000 pills, and in Seoul alone there were 8,149 recoveries. Knowing as we do the frightful ravages of this disease when it takes a virulent turn, the fact that there were over 8,000 recoveries in Seoul indicates that there must have been at least 60,000 deaths. Probably this was more than half the population of the city at that time. It was during this same year that the great mound in Kang-dong, P‘yŭng-an Province, was found. It is some 680 feet in circumference. It was called, from the first, the grave of the Tan-gun, though there is of course no evidence to show that this is more than the merest fancy. The king had a half brother named Prince Eun-ön for whom he had a great affection; but Hong Kuk-Yŭng whose daughter had been the king’s first concubine and had violently opposed a second union, now conspired with two other choice spirits with a view to putting Prince Eun-ön on the throne. The vigilant Queen Mother discovered the plot and the conspirators were executed. All likewise demanded the death of the young prince but to this the king would not listen. He was forced to banish him to Quelpart, but a short time after had him brought back as far as Kang-wha, where comfortable quarters were provided for him. The king interdicted the use of silk excepting by very high officials and by very old people. He set up stones to mark the place where the great-grandfather of T’ă-jo Tă-wang had lived, where his grandfather had fished and where that king himself had once lived, in Ham-gyŭng Province. Someone found in P’yŭng ch’ang, Ham-gyŭng Province, the grave of T’ă-jo Tă-wang’s great-grandmother and the king had it repaired and guarded. Up to that date the women had been accustomed to wear the hair in a great bunch on top of the head as female professional mourners do to-day in Korea. Large amounts of false hair were used and it was decorated with long pins and with flowers. It is said that a full headdress cost as much as the furnishings of a house. The king ordered a change in this expensive custom, and since that day only mourners and palace women have been allowed to wear them.
