They were two shrivelled, stunted, dried-up specimens of trees—two ghosts of palms—without foliage, and more dead than alive. Ferguson examined them with terror. At their feet could be seen the half-worn stones of a spring, but these stones, pulverized by the baking heat of the sun, seemed to be nothing now but impalpable dust. There was not the slightest sign of moisture. The doctor’s heart shrank within him, and he was about to communicate his thoughts to his companions, when their exclamations attracted his attention. As far as the eye could reach to the eastward, extended a long line of whitened bones; pieces of skeletons surrounded the fountain; a caravan had evidently made its way to that point, marking its progress by its bleaching remains; the weaker had fallen one by one upon the sand; the stronger, having at length reached this spring for which they panted, had there found a horrible death. Our travellers looked at each other and turned pale. “Let us not alight!” said Kennedy, “let us fly from this hideous spectacle! There’s not a drop of water here!” “No, Dick, as well pass the night here as elsewhere; let us have a clear conscience in the matter. We’ll dig down to the very bottom of the well. There has been a spring here, and perhaps there’s something left in it!” The _Victoria_ touched the ground; Joe and Kennedy put into the car a quantity of sand equal to their weight, and leaped out. They then hastened to the well, and penetrated to the interior by a flight of steps that was now nothing but dust. The spring appeared to have been dry for years. They dug down into a parched and powdery sand—the very dryest of all sand, indeed—there was not one trace of moisture! The doctor saw them come up to the surface of the desert, saturated with perspiration, worn out, covered with fine dust, exhausted, discouraged and despairing. He then comprehended that their search had been fruitless. He had expected as much, and he kept silent, for he felt that, from this moment forth, he must have courage and energy enough for three. Joe brought up with him some pieces of a leathern bottle that had grown hard and horn-like with age, and angrily flung them away among the bleaching bones of the caravan. At supper, not a word was spoken by our travellers, and they even ate without appetite. Yet they had not, up to this moment, endured the real agonies of thirst, and were in no desponding mood, excepting for the future. CHAPTER TWENTY-SIXTH.

The distance made by the balloon during the preceding day did not exceed ten miles, and, to keep it afloat, one hundred and sixty-two cubic feet of gas had been consumed. On Saturday morning the doctor again gave the signal for departure.
