This thought was some consolation to them, as they made their way through the dark passage, dimly illuminated by the lantern they had rekindled, to the place where Bill had hidden them. They found things as they had left them, and proceeded to get a meal, though Tom said it would be best not to cook anything, or even to make coffee, for fear the odors would enable the searchers to trail them.
So they ate cold food, glad to get that. Silently they sat about the dimly-lighted cavern, and discussed the situation. True they might even now retreat, going out of the entrance Bill had showed them, and so escape. But Mr. Jenks felt that his mission was not completed yet, and they all agreed to stay with him.
“For there are several points about making diamonds that are not quite clear to me,” he said. “I need to know how that steel box is constructed, how the electrical switches are arranged, what kind of lightning rods they use, and how they regulate the pressure. The other things, and how to mix the ingredients, I already know.”
“Then we'll do our best to help you,” promised Tom. “But now I think we had better see what sort of a defense we can put up. We have our guns and revolvers, and with these chairs and tables we can build a sort of barricade behind which we can take refuge if those fellows do discover our hiding place.”
This was conceded to be a good idea, and soon a rude sort of fort was made, behind which the adventurers could take their stand and fight, if necessary, though they hoped this would not come to pass.
They remained quietly in the cave the remainder of that day, and, when it was night, as they could tell by their timepieces—there was no daylight—they divided the hours into watches, taking turns standing guard.
Morning, at least in point of time, came without any disturbance, and they made a cold breakfast. They hoped that Bill Renshaw would come, but he did not appear.
After sitting in the dark cave until afternoon, Tom said:
“I think we might as well go and take another observation of the big cave. We can tell what the men are doing, then, for they don't seem to have been near us. Maybe they have given up the search for us, and we can see them at work, and Mr. Jenks can gain what further knowledge he needs.”
“That will be a good plan,” agreed the diamond man. “It's maddening to sit here, doing nothing.”
