"I shall have to warn you that anything you say can be used against you at your trial," said the sheriff sternly. "I have found the grave of the dead man near this camp." "Rats!" sneered McCarty angrily. "No sane judge would hold us ten minutes on such a charge." "Well," observed the sheriff coolly, "you will have a chance to test that. Even if I were convinced of your innocence, I would have to arrest you just the same. When a warrant is given me it is my sworn duty to serve it." "The sheriff is right," Charley said hopelessly. "We will have to go with him, and we might as well do it without argument. The judge will turn us loose as soon as he hears our story, but it will be too late then." "Too late for what, lad?" asked Captain Westfield. "Why, can't you see this warrant is a put-up job," Charley exclaimed impatiently. "Don't you understand it's the latest move of the enemy to get us out of the way while they disable the machine and destroy our camp?" "By Jove, I believe you're right," exclaimed McCarty. "Right, of course I'm right," said the lad fiercely. "What other reason could there be for such an absurd charge? You will see that no one will appear against us when we are brought up in court. Well, the game's up, boys. We have all put up a good fight, but this settles it. I would not give ten cents for what we will find here if we return after being set free. May we have time enough, Mr. Sheriff, to pay off our men and pack up our things?" "You can have all night," replied the officer. "We will not go in until morning. It's a long journey, for, with the bridges gone, we will have to pick our way back through the woods." After our little party had finished a silent, gloomy supper, they retired to their tents to pack up their scattered belongings. Charley called the workers to his tent one by one and gave each a check for a full month's wages. He made all of them promise to stay and guard camp and machine during their absence, but he really had but little hope that they would remain in camp long after all the Americans were gone. Their packing done, the little party gathered around the campfire as gloomy and disheartened a little bunch of men as it would be possible to find. One of the larger of the tents had been given up to the sheriff and his posse, and to it the officer sent his tired men early, saying he would stand guard over the prisoners himself the first part of the night. "Boys," he said, when the last one of his men had retired, "I hate to execute this warrant. I had to be stern to you before my men, for every one of them wants my job and would be glad to make any trouble they could for me at headquarters. Being as we are alone together now, I will say that I believe you fellows are as guiltless as a babe of the crime with which you are charged. I believe, as you say, that it's a frame-up, but I've got to take you all in to answer to it, unless----" "Unless what?" asked Walter eagerly.
