The tribe of Ok-jŭ was finally absorbed in Ko-gu-ryŭ in the fourth year of King T’ă-jo Wang.
The Eum-nu tribe did not belong to Korea proper but as its territory was adjacent to Korea a word may not be out of place. It was originally called Suk-sin. It was north of Ok-jŭ and stretched from the Tu-man river away north to the vicinity of the Amur. Its most famous mountain was Pul-ham San, It is said to have been a thousand _li_ to the north-east of Pu-yŭ. The country was mountainous and there were no cart roads. The various cereals were grown, as well as hemp.
The native account of the people of Eum-nu is quite droll and can hardly be accepted as credible. It tells us that the people lived in the trees in summer and in holes in the ground in winter. The higher a man’s rank the deeper he was allowed to dig. The deepest holes were “nine rafters deep.” Pigs were much in evidence. The flesh was eaten and the skins were worn. In winter the people smeared themselves an inch thick with grease. In summer they wore only a breach-cloth. They were extremely filthy. In the center of each of these winter excavations was a common cesspool about which everything else was clustered. The extraordinary statement is made that these people picked up pieces of meat with their toes and ate them. They sat on frozen meat to thaw it out. There was no king, but a sort of hereditary chieftainship prevailed. If a man desired to marry he placed a feather in the hair of the damsel of his choice and if she accepted him she simply followed him home. Women did not marry twice, but before marriage the extreme of latitude was allowed. Young men were more respected than old men. They buried their dead, placing a number of slaughtered pigs beside the dead that he might have something to eat in the land beyond the grave. The people were fierce and cruel, and even though a parent died they did not weep. Death was the penalty for small as well as great offences. They had no form of writing and treaties were made only by word of mouth. In the days of Emperor Yüan-ti of the Eastern Tsin dynasty, an envoy from this tribe was seen in the Capital of China.
We have described the tribes of eastern Korea. A word now about the western part of the peninsula. All that portion of Korea lying between the Han and Yalu rivers constituted what was known as Nang-nang and included the present provinces of P‘yŭng-an and Whang-hă together with a portion of Kyŭng-geui. It was originally the name of a single tribe whose position will probably never be exactly known; but it was of such importance that when China divided northern Korea into four provinces she gave this name of Nang-nang to all that portion lying, as we have said, between the Han and the Yalu. The only accounts of these people are given under the head of the Kingdom of Ko-gu-ryŭ which we shall consider later. But between Nang-nang and the extreme eastern tribes of Ok-jŭ there was a large tract of country including the eastern part of the present province of P’yŭng-an and the western part of Ham-gyŭng. This was called Hyŭn-do, and the Chinese gave this name to the whole north-eastern part of Korea. No separate accounts of Hyŭn-do seem to be now available.
