It flows until it exits from its north, and on it are their millstones with which they grind wheat. This river enters the city on Thursday, Friday, Saturday, and Sunday. On the Friday of the week, they take it for the irrigation of their gardens and lands, and divert it from the city, so that nothing of it flows into the city. The city of Aghmat is a city surrounded by the mountain of Durn, as we have said. When it is winter, the snow falling on the mountain (Durn) melts and flows into the city of Aghmat. Sometimes the river freezes in the middle of the city until it passes over it while it is frozen, and it does not break because of its intense freezing. This is something that has happened there more than once. The people of Aghmat are Hawara, from the Berber tribes who settled in the neighboring areas. There are wealthy, prosperous merchants who enter the land of Sudan with large numbers of camels carrying various goods: red copper, tin, lead, iron tools, turbans, and various kinds of dyes, spices, perfumes, and manufactured iron tools. Not a single man among them, except for their slaves and millstones, was born into a family with less than forty, seventy, or eighty camels, and all of them were abundant. In the state of Al-Mutalmi', no one was richer than them in wealth or more prosperous in their circumstances. At the entrances of their homes are signs indicating the sources of their wealth, for when a man among them owned four thousand dinars, he would keep them with himself, and four thousand he would invest in his trade. He would place on the right of his door, and on his left, two strips of land.
