At midnight he came to, in the arms of his faithful follower, Joe. The latter, uneasy at his master’s prolonged absence, had set out after him, easily tracing him by the clear imprint of his feet in the sand, and had found him lying in a swoon. “What has been the matter, sir?” was the first inquiry. “Nothing, Joe, nothing! Only a touch of weakness, that’s all. It’s over now.” “Oh! it won’t amount to any thing, sir, I’m sure of that; but get up on your feet, if you can. There! lean upon me, and let us get back to the balloon.” And the doctor, leaning on Joe’s arm, returned along the track by which he had come. “You were too bold, sir; it won’t do to run such risks. You might have been robbed,” he added, laughing. “But, sir, come now, let us talk seriously.” “Speak! I am listening to you.” “We must positively make up our minds to do something. Our present situation cannot last more than a few days longer, and if we get no wind, we are lost.” The doctor made no reply. “Well, then, one of us must sacrifice himself for the good of all, and it is most natural that it should fall to me to do so.” “What have you to propose? What is your plan?” “A very simple one! It is to take provisions enough, and to walk right on until I come to some place, as I must do, sooner or later. In the mean time, if Heaven sends you a good wind, you need not wait, but can start again. For my part, if I come to a village, I’ll work my way through with a few Arabic words that you can write for me on a slip of paper, and I’ll bring you help or lose my hide. What do you think of my plan?” “It is absolute folly, Joe, but worthy of your noble heart. The thing is impossible. You will not leave us.” “But, sir, we must do something, and this plan can’t do you any harm, for, I say again, you need not wait; and then, after all, I may succeed.” “No, Joe, no! We will not separate. That would only be adding sorrow to trouble. It was written that matters should be as they are; and it is very probably written that it shall be quite otherwise by-and-by. Let us wait, then, with resignation.” “So be it, master; but take notice of one thing: I give you a day longer, and I’ll not wait after that. To-day is Sunday; we might say Monday, as it is one o’clock in the morning, and if we don’t get off by Tuesday, I’ll run the risk. I’ve made up my mind to that!” The doctor made no answer, and in a few minutes they got back to the car, where he took his place beside Kennedy, who lay there plunged in silence so complete that it could not be considered sleep.

The doctor’s first care, on the morrow, was to consult the barometer. He found that the mercury had scarcely undergone any perceptible depression. “Nothing!” he murmured, “nothing!”
