From Jabal al-Hadid, 90 miles. From the edge of Jabal al-Hadid to the oasis in al-Sukun, 5 miles. Likewise, from the edge of Marin to Asfi, 85 miles, and to Taghawra, 130 miles. Asfi was formerly the last port reached by ships. However, it is now navigable by more than 4 channels. Asfi has buildings, and many of the Berbers called Ragraja and Zayda, and other Berbers, load their goods onto ships there when traveling and the sea is calm. This port was named Asfi for a reason we will mention when we discuss the city of Ishbiliya in the western lands of al-Andalus. We mention things in their proper place, and praise be to God. From the port of Asfi to the port of Massa, in the direction of the coast, 15 miles. The port of al-Ghayth is a good port, protected by some of the surrounding areas. Ships reach it and unload grain and wool. From the Berber tribes, it is connected to Dukana and Aris. Dukana is like a market, a place of trade, and a destination. It extends from Dukana to the port of Manast, to Narudant in the Sus. It is inhabited by a group of the Masamida. Then, Harab, Zay, and Muwas Khantir. We have mentioned this before. From the city of Aghmat, to the east and north, to the cities of Day and Tadla, 4 days. From Day and Tadla, one stage. The city of Day is at the foot of a mountain, outside Jabal Durn. It is a city with a mine of pure copper, unmatched by any other copper in the east and west of the earth. It is sweet copper, its color tending towards red, and it is durable. It is used in the refining of silver, and when it is heated, it does not expand as other types of copper do. The common people attribute this mine to the Sus, but the city of Day is not part of the Sus, because their distance is considerable.
