_"A.D. 379. This year, at a fork of the River Kahashima, in the central division of the Province of Kibi, there was a great water-dragon which harassed the people. Now when travellers were passing that place on their journey, they were sure to be affected by its poison, so that many died. Hereupon Agatamori, the ancestor of the Omi of Kasa, a man of fierce temper and of great bodily strength, stood over the pool of the river-fork and flung into the water three whole calabashes, saying: 'Thou art continually belching up poison and therewithal plaguing travellers. I will kill thee, thou water-dragon. If thou canst sink these calabashes, then will I take myself away, but if thou canst not sink them, then will I cut thy body to pieces.' Now the water-dragon changed itself into a deer and tried to draw down the calabashes, but the calabashes would not sink. So with upraised sword he entered the water and slew the water-dragon. He further sought out the water-dragon's fellows. Now the tribe of all the water-dragons filled a cave in the bottom of the pool. He slew them every one, and the water of the river became changed to blood. Therefore that water was called the pool of Agatamori."_ _"A.D. 323. In order to prevent the overflowing of the Northern river the Mamuta embankment was constructed. At this time there were two parts of the construction which gave way and could not be stopped up. Then the Emperor had a dream, in which he was admonished by a God, saying: 'There are a man of Musashi named Koha-kubi and a man of Kahachi named Koromo no ko, the Muraji of Mamuta. Let these two men be sacrificed to the River-God, and thou wilt surely be enabled to close the gaps.' So he sought for these two men, and having found them, offered them to the River-God. Hereupon Koha-kubi wept and lamented, and plunging into the water, died. So that embankment was completed. Koroma no ko, however, took two whole calabashes, and standing over the water which could not be dammed, plunged the two calabashes into the mid-stream and prayed, saying: 'O thou River-God, who hast sent the curse [to remove which] I have now come hither as a sacrifice! If thou dost persist in thy desire to have me, sink these calabashes and let them not rise to the surface. Then shall I know that thou art a true God, and will enter the water of my own accord. But if thou canst not sink the calabashes, I shall, of course, know that thou art a false God, for whom why should I spend my life in vain?' Hereupon a whirlwind arose suddenly which drew with it the calabashes and tried to submerge them in the water. But the calabashes, dancing on the waves, would not sink, and floated far away over the wide waters. In this way that embankment was completed, although Koromo no ko did not die. Accordingly Koromo no ko's cleverness saved his life. Therefore the men of that time gave a name to these two places, calling them 'Koha-kubi's Gap' and 'Koromo no ko's Gap.'"_
