The day passed like every other day. At sundown the bugle's note drew the men from their work. They returned to their several quarters, and after their evening meal settled down to their games of chance or skill.
After supper, when pipes were lit, Mr. Appleton returned to the subject.
"I haven't a doubt that Nurla is the man," he said. "You remember his industry when you were building your bridges. The scoundrel's motive is clear. The question is, what is he after? It can't be mere inquisitiveness. He suspects that the Pathans are mining something more valuable than copper, and if he can prove it, he'll sell his knowledge, I suspect, and we shall have trouble. I only hope that your appearance last night disturbed him before he had had time to get any samples."
"If it didn't?" said Bob.
"He'll probably try again. The fact that he hasn't absconded seems to show that he isn't satisfied. If he had got enough for his purpose he would have been over the hills before this. We must keep a strict watch, and if we catch him making any further attempt of the same kind it's the sack at once."
"Wouldn't it be best to sack him now?" Lawrence suggested.
"I'm rather loth to act without definite proof. We should make an enemy of the fellow needlessly, and he has such influence with the Kalmucks that he might call them all out."
"Would that matter? The silver's the thing," said Lawrence.
"Not at all. If I went on mining without them it would be a clear proof that I could afford to leave their gallery unworked, and there'd be trouble all the same. There'll probably be trouble anyhow, but I'd rather keep the Kalmucks working quietly as long as possible. Meantime we'll take precautions. I'll put a Sikh in the Pathan section to keep guard through the night, and withdraw him before dawn, so that nobody is any the wiser."
Early next morning, a few minutes after the bugle had sounded réveille, the Englishmen were disturbed in their dressing by the sound of a great uproar from across the river. They flung on their coats and hurried out. The drawbridge had not been lowered; half an hour would elapse before the bugle called the men to work. But at the farther end the Pathan miners had assembled, and were gesticulating in much excitement, shouting lustily for the huzur. Mr. Appleton ordered the drawbridge to be let down, and hastened across to meet the men.
