“All right,” returned Dr. Kirshner. “I’m anxious to make a casual study of them. They might have some primitive implements that belonged to their remote ancestors.”

The adventurers made their way down the hill and mounted their camels. Then they rode off toward the distant valley. It was a good distance away, and perhaps hard of access, but the explorers were determined to find it.

In less time than they had expected, they came to a spot that would probably afford an opening into the valley. For a few minutes they wound in and out among the rocks. Then they came within sight of the village.

A crowd of Arabs ran out to meet them, uttering hearty greetings. It was evident that expeditions rarely passed within sight of their dwellings, for they were very excited.

Tishmak and Fekmah conversed with the people in a very friendly manner and then introduced the others of the American expedition.

Dr. Kirshner and the naturalists found it almost impossible to understand the language, and they were satisfied with Fekmah’s translations.

“A good chance to take some movies,” said Bob, getting out the camera.

“Don’t suppose the Arabs would object,” added Joe. “At any rate, we’ll risk it.”

The youths cranked off several scenes of the Arabs and their village. It was clear to the explorers that the people had never seen a motion-picture camera before. The strange purring box was an object of curiosity, and they crowded around like so many children.
