The second mountain, which is to the north of this mountain, they call the Mountain of Gold, because it contains gold mines. As for the third mountain, which is to the east of the second mountain, and in the land where it is, they call it the Land of Snakes. The people of that land claim that there are great snakes there that kill by sight. In this mountain, which is in this mentioned land, there are scorpions the size of sparrows, black in color, which kill instantly. This has been mentioned by the author of the Book of Wonders. He also mentioned in the Book of the Treasury of Al-Qudama that the course of the Nile from its source to its mouth in the Syrian Sea is five thousand, six hundred, and thirty-four miles. The width of the Nile in the land of Nubia is one mile, as narrated by the author of the Book of Wonders. Its width in the Fayoum of Egypt is one-third of a mile. In the small lakes and beyond, there is an animal called the crocodile. There is also a fish called the pig, which has a snout larger than a buffalo. It comes out to the neighboring areas of the Nile and eats the crops there, then returns to the Nile. In the mentioned Nile, there is a round fish with a red tail called Al-Ash. It appears rarely, but it is plentiful in flesh and good in taste. There is also a fish called Al-Abramis, which is a white, round fish with a red tail. It is said to be the king of fish. It is good in taste and delicious, eaten fresh or salted. However, it is delicate, about a span in length and half of that in width. There is also Al-Ri, which is a large, red fish, some large and some small. The large ones may weigh three ratls or less. It is good in taste, close to the taste of the fish called Al-Abramis. There is also a fish called Al-Bunni, which is large and has a wonderful and delicious taste. Sometimes one of them weighs five ratls, ten ratls, or more or less. There is also a type of fish called Al-Baladi, which is round.
