At this time it came to pass that Yaniah, the wife of King Agnias, fell into a grievous sickness, and the physicians ascribed her illness to the climate, and to the water of Africa, to which she, a native of the land of Kittim, could not get accustomed, because she had been in the habit of using the water of the river Forma, which her forefathers had drawn to her house through a conduit. Agnias sent to the land of Kittim and had some of the water of the Forma brought to Africa. Finding it much lighter than the water of his own country, he built a huge canal from the land of Kittim. to Africa, and the queen henceforth had all the Forma water she needed. Besides, he took earth and stone from Kittim, and built a palace for Yaniah, and she recovered from her illness.
