The foreman saw to replacing the screens, and, when the mill was again started, he went to the superintendent's office. He knew very well that an unpleasant time awaited him; but, like the superintendent, he had his course of action mapped out. The foreman was a very wise man within a restricted circle. He knew that the battle was his, if he fought within its circumference. Outside of the circle he did not propose to be tempted. Firmstone could not force him out. Those who could, would not attempt it for very obvious and personal reasons. Luna was aware that Firmstone knew that there was thieving, and was morally certain as to who were the thieves, but lacked convincing proof. This was his protecting circle. Firmstone could not force him out of it. Morrison and Pierre knew not only of the thieving, but the thieves. They could force him out, but they would not. Luna was tranquil.
Luna saw Firmstone in the laboratory as he entered the railed enclosure. He opened the railing gate, passed through the office, and entered the laboratory. Firmstone glanced at the foreman, but he met only a stolid face with no sign of confusion.
"Pan these samples down."
Without a word Luna emptied the sacks into little pans and carefully washed off the crushed rock, leaving the grains of gold in the pans. Eight of the pans showed rich in gold, the last two hardly a trace.
Firmstone placed the pans in order.
"What do you make of that?" he asked, sharply.
Luna shook his head.
"That's too much for me."
"What batteries did these two come from?" Firmstone pointed to the two plates.
"Nine and Ten," the foreman answered, promptly.
