The marabout said to me: “I believe now in your supernatural power. You are really a sorcerer. I hope, therefore, you will not refuse to repeat here an exhibition of your powers made on your stage.” He gave me two pistols, which he had concealed under his bournous, and said: “Choose one of those pistols; we are going to load it, and I shall fire it at you. You have nothing to fear, since you know how to parry any bullet.” I confess I was for a moment dumb with embarrassment. I tried my best to think of some subterfuge, but I could think of nothing. Every eye was fixed on me, in expectation of my reply. The marabout was triumphant. Bou Allem, who knew that my tricks were due solely to my adroitness, became angry that his guests should be annoyed in this barbarous way, and he scolded the marabout. I stopped him. An idea had struck me which would at least extricate me for the moment from my embarrassment. So I said to the marabout, speaking with all the assurance I could summon: “You know that I am not invulnerable unless I have a talisman on me. Unfortunately, I have left it at Algiers.” The marabout began to laugh incredulously. “Nevertheless,” I went on to say, “if I remain in prayer for six hours, I shall be able to make myself invulnerable to your pistol, even though I have no talisman. To-morrow morning, at eleven o’clock, I shall let you fire at me before all these Arabs, who are witnesses of your challenge.” Bou Allem, astonished to hear me make such a promise, came up and asked me in a low tone if I was speaking seriously, and if he should invite the Arabs to come the next day. I told him I was. I need not say I did not spend the night in prayers, but I worked for two hours to make myself invulnerable, and then satisfied with my success, I went to sleep with a great deal of pleasure, for I was horribly tired. We breakfasted before eight o’clock, the next morning; our horses were saddled, and our escort was waiting the signal of departure, which was to take place immediately after the famous experiment. The same persons who were present at the challenge the day before, were at the rendezvous, and a great many other Arabs who had heard of what was to take place, had come to witness it.
