Sometimes the floor space is extended by an artificial terrace in front of the cave.

In a few cases the floor is plastered with adobe, and I have seen one cave in which the sides, too, were dressed in the same way.

Generally there are one or two store-houses in the caves, and these constitute the chief improvement.

Of course, there are a good many caves where there are no storehouses; still they are the striking feature of the cave.

A few times I found walls of stone and mud erected inside of the cave, breast high, to partition off one or two rooms for the use of the family, as well as for the goats and sheep.
