It is important to notice that the island of Tsushima, whether actually conquered by Sil-la or not, became a dependency of that Kingdom and on account of the sterility of the soil the people of that island were annually aided by the government. It was not until the year 500 A.D. or thereabouts that the Japanese took charge of the island and placed their magistrate there. From that time on, the island was not a dependency of any Korean state but the relations between them were very intimate, and there was a constant interchange of goods, in a half commercial and half political manner. There is nothing to show that the _daimyos_ of Tsushima ever had any control over any portion of the adjacent coast of Korea. It gives one a strong sense of the trustworthiness of the Korean records of these early days to note with what care the date of every eclipse was recorded. At the beginning of each reign the list of the dates of solar eclipses is given. For instance, in the reign of Hyŭk-kŭ-se they occurred, so the records say, in the fourth, twenty-fourth, thirtieth, thirty-second, forty-third, forty-fifth, fifty-sixth and fifty-ninth years of his reign. According to the Gregorian calendar this would mean the years 53, 31, 27, 25, 14, 12 B.C. and 2. A.D. If these annals were later productions, intended to deceive posterity, they would scarcely contain lists of solar eclipses. The marvelous or incredible stories given in these records are given only as such and often the reader is warned not to put faith in them. The year 48 B.C. gives us the first definite statement of a historical fact regarding Japanese relations with Korea. In that year the Japanese pirates stopped their incursions into Korea for the time being. From this it would seem that even at that early date the Japanese had become the vikings of the East and were carrying fire and sword wherever there was enough water to float their boats. It would also indicate that the extreme south of Korea was not settled by Japanese, for it was here that the Japanese incursions took place.
