The earth train, and that is because this mine is served by more than a thousand men. Some are engaged in digging and cutting stone, and some are occupied with transporting firewood for burning and for the mine. Others are involved in making furnaces for smelting lead and for its elevation. And some are concerned with the affairs of the furnaces and the burning. The observer said, "I have seen this mine, and I was informed that from the surface of the earth to its bottom there are more than two hundred and fifty levels. From Cordoba to Granada are stages, which is a hundred miles. Between Granada and Jaén are two stages, which is four miles. As for the Sea of Syria, which lies to the south of the land of Al-Andalus, its beginning is from the west, and its end is where it reaches. The distance between them is thirty-four days of sailing. As for its width, it varies. This is because the city of Malaga is opposite the other side, Al-Muzda and Yas, and the width of the sea between them is one day's sail with a good, moderate wind. Likewise, Almería is parallel to it on the other side, and the width of the sea between them is two days' sail. Similarly, the city of Denia is opposite the other side, Tunis, and the distance between them is three days' sail. Likewise, the city of Barcelona is opposite the western middle coast, Bejaia, and the distance between them is four days' sail. The width of the sea and the sailing days are a hundred miles. As for the island of Ibiza, it is a beautiful island with many vines and grapes, and it has a beautiful, small, populous city. The closest island to it is the city of Denia, and the distance between them is one day's sail. To the east of Ibiza is the island of Formentera, and the distance between them is one day's sail. It has a large city with a ruler, a guardian with men, soldiers, weapons, and wealth. To its east is also the island of Menorca, opposite the city of Barcelona, and the distance between them is one day's sail. From Menorca to the island of Sardinia are four days' sail. That is what we wanted to mention. And the fish and pricing. And the elevation. And the elevation. And the fourth region, and praise be to God. And praise be to God, we will mention from it, God willing.
