What was the explanation of this maneuvre? Simply that Ali saw looming ahead the shadowy outlines of the tall feathered palm trees constituting the little oasis, and had no desire to charge blindly without preparation or plan.
Mr. Hampton urged his camel alongside that of Ali, and the boys also approached. Although twenty-five years older than his son, Mr. Hampton had an iron frame inured to fatigue through years of roughing it in the out-of-the-way places of the world. He was less blown as a result of the wild ride than the young fellows.
Long since he had given up any idea of keeping the boys out of danger. All were strong and cool-headed in emergencies, and he had received plenty of evidence during recent years that they could take care of themselves.
Rapidly he outlined what was to be done. Let all dismount, hobble the camels and leave them in charge of two of Ali’s men, and the balance of the party, consisting of Ali, four Arabs, the three boys and himself, nine in all, would advance afoot. In this way, the noise of their approach could be minimized. Besides, so far as four of their number were concerned, they would be better able to render a good account of themselves than if on camel back.
Ali acquiesced, the necessary commands were given, and all caused their camels to kneel while they dismounted. Then two of the number were left adjusting hobbles and guarding the animals, while the others spread out a yard apart, and began to steal forward.
CHAPTER III.
THE MYSTERY AT THE OASIS.
There is something wonderfully exhilarating in night on the open desert. The boys felt it, so did Mr. Hampton. Who knows? Perhaps Ali and the Arabs were subject to this mysterious influence, too. Shortly, a little after seven as they knew from experience, the moon would be up, silvering the plain. All now, however, was in darkness except for the dim light of the stars. Yet it was a darkness filled with caressing breezes and the feeling of beauty.
Despite the adventurous quest upon which they were embarked, despite the possibility, nay, the probability, that in a moment the night would be shattered with strife and death, each found himself yielding insensibly to this softening influence.
Suddenly the howling of a dog broke the stillness. It was a long wailing cry that made the nerves quiver and caused each member of the party to grow tense. When does a dog howl like that? Ali and the Arabs knew. The rest, with their sensitive intelligences, guessed at the meaning. That howl meant mourning over a fallen master.
As if it were a signal, other dogs joined in. A whole chorus of wailing notes effectively shattered the stillness of night.
