An extract, when applied to animal skin, removes hair. And the bark of the *laha* tree has fine threads like a pulpit, which are gathered and spun into threads useful for mending waterskins.

It is a light wild plant, like the desert grass. And behind them, they lightly blacken gunpowder. Or *asnad* or *za'bal*, a fruit from it. And in Upper Egypt, there is much of it. And from it is the *tajrim al-hashab*, which is a thorny tree, and from it is taken gum arabic. I have seen it and gathered gum from it, soft and stretched like licorice. And in arid, sandy places. And from it is the *sunt*, which is the *qurut* tree, a large thorny tree. And from it is the *talh*, which is from the *sunt* family. The *talh* is a tree that grows taller than a man, and its branches are covered with long thorns like eyebrows. Its leaves are compound, made of small leaflets. And the *sayyal* is a long fruit that grows taller than a man, but smaller than the *talh*. Its peel is green with a whitish tinge, and it has white thorns. Its leaves are compound, made of leaflets.
