“I tink heem bout right,” and the Frenchman cast an admiring glance toward Jack. “I tink heem key log, oui.” “See if you can budge it,” Mr. Golden proposed. But although Jean sank the sharp end of his peavey deep into the log and exerted all his great strength, he was unable to move it. “Have to feex heem wid powder, oui,” he panted after he had pushed and pulled for some minutes. “It’s going to be a pretty hard job to get the dynamite in the right place don’t you think, Jean?” Jack asked. “Oui, heem be ver’ hard but I feex heem,” and the Frenchman started for the shore while the others sat down on a log to await his return. It was only a short time before they saw him coming back unwinding a coil of wire as he stepped from log to log. “Where are you going to place it?” Jack asked, as Jean reached them and took two sticks of dynamite from his pocket. “I have geet heem down close by dat rock, oui,” Jean replied as he took off his heavy calked boots and rolled up his trousers. “He isn’t going to step in that ice cold water, is he?” Rex whispered to Jack, who was standing close by him. “He doesn’t mind that,” Jack laughed. “You see a river driver’s feet are wet about all the time he is on the drive, and they get used to it.” “But I should think they would catch their death of cold,” Rex declared. “So would I, but they don’t seem to,” Jack laughed. “I guess they must be immune or something of the kind.” While they were talking the object of Rex’s concern had walked out on the overhanging log and had swung himself off to the rock. As he stood on it the icy water was well above his knees, but as Rex afterward declared he did not so much as shiver, Feeling with his toes he soon found a place to his liking and in another minute he had the two cylinders of dynamite securely fastened between the rock and the key log. “Now we soon know if she go bust,” he declared as he jumped back to the log and quickly drew on his heavy woolen socks and boots. They all followed him to the shore where he had left the battery. “You found the key, if that’s the one, and it’s up to you to press the button, Jack,” Mr. Golden declared, as they waited for the rest of the crew to join them. “All right, now. Let heem go bust,” Jean shouted, as the last of the men jumped to the shore. Immediately Jack pressed the button while they all held their breath. A heavy explosion followed and a mass of water was thrown in the air. For an instant there seemed to be no movement of the logs and Jack was about to voice his disappointment, when suddenly a shudder seemed to shake the jam and, with a rending sound, the foremost logs began slowly to writhe. “Hurrah! She go bust!” Jean shouted, jumping up and down in his excitement. “Bust is right,” Mr. Golden agreed; then turning to Jack, he declared: “My hat off to you, son. You’re the champion key log finder of the outfit.”
