Strange also are the citron and the sweet cane, so much so that the people of this mountain do not sell or buy them among themselves due to their abundance. They also have olive trees, carob trees, and other desirable fruits. In this mountain, there is a large tree called in Berber "Arfan," which resembles pear trees in its branches, boughs, and leaves. It has a fruit similar to the fruit of the 'uyun in its early stages. Its outer peel is thin and green, and when it ripens, it turns yellow, but it is extremely astringent and sour. Inside, there is a stone similar to a pointed olive stone, hard, and the taste of this fruit is not pleasant. However, at the end of September, it is gathered and placed before goats, which swallow it after eating its outer peel. Then they regurgitate it. It is then collected, washed, broken, pounded, and pressed, yielding a large quantity of oil, white in color, wondrous to behold. However, its taste is not sweet, with a slight acridity. This oil is very abundant and well-known in the farthest western lands. They use it to light their lamps, and the dyers fry sponges in it in the markets. When it is touched by fire, it emits a foul, sharp odor, but its taste is pleasant in sponges. The women of the Mahamida tribe anoint their heads with it on their combs, which improves their hair, making it soft and less prone to breaking, and it keeps the hair its black color. The city of Aghmat is located below this mountain to its north, in a wide plain with fertile soil, abundant vegetation, herbs, and water that flows through it from right to left. It is watered day and night, and around it are gardens, orchards, and dense trees. Its location is the most pleasant place on earth, with spacious surroundings, fertile soil, sweet water, and healthy air. A river, not very large, flows through the city, coming from the south.
