I saw also what seemed a small but well-equipped machine shop, in a recess room at one side of the cave. Men were working in there under the light of tubes. And there was a niche hollowed out in the wall to make a room for De Boer's instruments--ether-wave receivers and transmitters, the aerial receiving wires of which stretched in banks along the low ceiling. There was no activity in there now, except for one man who was operating what I imagined might be an aerial insulator, guarding the place from any prying search-vibrations. The main cave was a bustle of activity. The arriving bandits were greeting their fellows and exchanging news. The men who had been left here were jubilant at the success of the Chief's latest enterprise. Bottles were unsealed and they began to prepare the morning meal. My presence caused considerable comment. I was a complication at which most of the men were ill pleased, especially when the arriving bandits told who I was, and that the patrols of the United States were doubtless even now trying to find me. But De Boer silenced the grumbling with rough words. "My business, not yours. But you will take your share of his ransom, won't you? Have done!" And Jetta, she had caused comment also. But when the bottles were well distributed the grumbling turned to ribald banter which made me shudder that it should fall upon Jetta's ears. De Boer had kept his men away from her, shoving them aside when they crowded to see her. She was in a little tent now, not far from the base of my ledge. My meal presently was brought from where most of the bandits now were roistering at the long table in the center of the cave. "Eat," said Gutierrez. "I eat with you, Americano. _Madre Mia_, when you are ransomed away from here it will please me! De Boer is fool, with taking such a chance." * * * * * With the meal ended, another guard came to take Gutierrez' place and I was ordered into my tent. The routine of the camp, it seemed, was to use the daylight hours for the time of sleep. There were lookouts and guards at the entrance, and a little arsenal of ready weapons stocked in the passage. The men at the table were still at their meal. It would end, I did not doubt, by most of them falling into heavy alcoholic slumber. I was tired, poisoned by the need of sleep. I lay on fabric cushions piled in one corner of my tent. But sleep would not come; my thoughts ran like a tumbling mountain torrent, and as aimlessly. I hoped that Jetta was sleeping. De Boer was now at the center table with his men. Hans was guarding Jetta. He was a phlegmatic, heavy Dutchman, and seemed decent enough. I wondered what Hanley might be doing to rescue me. But as I thought about it, I could only hope that his patrols would not find us out here. An attack and most certainly De Boer and his men in their anger would kill me out of hand. And possibly Jetta also.
