"That's about as savage, bloodthirsty a brute as his younger companion," said the professor softly; "but he's a brave man." "Yes," said Frank laconically, as he kept his eyes fixed nervously upon the chief. "Think he'll be able to keep his seat?" "I hope so." "So do I, for if he comes off with a thud I won't give much for our lives. Hah! he has mastered it." "Yes, he has mastered it all," said Frank. "He must have been horribly sick and faint." "And that ammonia is not a very exhilarating draught to take. I know the abomination pretty well. Soap and water is delicious in comparison, especially if it is scented." All this time the Hakim stood motionless, watching his patient gravely, and waiting for the result which soon came. For the peril had passed, the Baggara chief drawing himself up in his saddle, making his beautiful Arab charger rear up, and then letting him gallop for a hundred yards or so in full sight of his men, who began to shout frantically. Then pulling the horse down upon its haunches, he turned, galloped back, and checked the graceful creature again in front of the Hakim, to bend over and say a few words before rejoining his brother chief. "What said he, Ibrahim?" asked the doctor in a whisper, without moving his head or seeming to speak. "That the Hakim is a great prophet, and that it is peace. Excellency, they will not hurt us now." This was soon made evident, for the younger chief began to give orders, and the men dismounted and formed themselves into a camp about a hundred yards away from the Hakim's tent. Then in fairly regular order the horses and camels were led up to the water, allowed to drink, and then led away, all being done so as not to interfere with Ibrahim's train of camels, which were now pastured on the other side of the tent, to which the Hakim had returned, and where Frank, the professor, and Sam were busy replacing the various articles that had been brought out. Here a little conference was held around the doctor, who had resumed his calm and thoughtful attitude, but who, beneath his solemn aspect, was as excited as the rest. "Well, Frank, lad," he said, "did it go satisfactorily?" "Of course," replied the young man; "how could it be otherwise. It was real." "Splendid," said the professor. "Robert, old fellow, I was proud of you." "I don't think you would have been, Fred, if you could have seen inside." "What do you mean--not nervous?" "I was never worse in my life. I wonder I got through it as I did. You both noticed how my hands shook." "That I did not," said Frank warmly. "You seemed to me as firm as a rock." "Appearances are very deceitful," said the doctor with a quaint look. "Well, I did my best for him. He was in a terrible state." At that moment the Sheikh, who had been giving orders to his young men not to let the camels stray, rejoined them, and he gave the doctor a look full of reverence.
