One reason is that they follow their cattle; another that they improve the land by living on it for a while; but there are still other reasons for moving so much about, which are known only to themselves.

In summer many people leave their caves on account of the scorpions, tarantulas, and other pests that infest them.
In front of the entrance to the cave there is generally a wall of stone, or of stone and mud, raised to the height of a man's chest, as a protection against wind and weather, wild beasts, etc.

The cave is fitted up just like the houses, with grinding stone, earthen jars and bowls, baskets, gourds, etc, The fire is always in the middle, without hearth or chimney, and the jars in which the food is cooked rest on three stones.

A portion of the ground is levelled and made smooth for the family to sleep on.

As often as not there are skins spread out on the floor.
