In the wuxu year of the Dade era (1298), there was an ancient dyke at the southern fringe of the various prefectures’ salt production offices. The dyke was thirty li from the sea, but the ground extending from it was very alkaline and the swell of the tide eroded the dyke every year, flooding the salt-works. The power of the sea encroached upon the prefectural capital, and when news of this reached the government office, they built up the dyke across more than two hundred zhang (660m), but within three days it had collapsed again. Everyone said that water demons had caused the damage, and that this was not something people could repair. The provincial council informed the Department of State Affairs, who respectfully received the letter and courteously invited the thirty-eighth Celestial Master to hurry and visit Hangzhou. At that time the provincial officials combined to make five days of offerings, day and night, beginning from the first day of the fifth month (10 June, 1298). When these offerings were finished, the Celestial Master sent a Master of the Law on board a boat, to throw an iron tally into the river. Initially the iron tally bounced and leapt among the waves, but after a moment it sank, wind, thunder, lightning and fog circling and winding around it. The following day they looked at the river and saw the sand rising through the day, and the dyke returned to its previous form, rising out of the river’s centre. In a depression on the sand there was a strange thing, killed by a lightning strike upon it, and more than two zhang (6.6m) across, shaped like a soft-shelled turtle, but bearing a shell. The provincial office sent a memorial to the court upon hearing of it, and they received lofty and generous commendation and reward.
