Shadrack's head appeared above the edge of the tender presently. He motioned to Tom. "This wood is so wet we can't light it. We haven't any paper." "Wait," ordered Tom. He grabbed a log from the tender and went to the fire-box, thrusting one end into the blaze. "I'll have to pass the fire back to them," he explained to Andrews. "The wood is too wet." When the end of the log was blazing, he pulled it out and raced back to Shadrack. The wind and the rain extinguished the flames, but he hurried forward again determinedly. This time he lighted several of the smallest logs, which burned more freely. He made three trips to the freight car, each time carrying a blazing torch, and he had just stepped into the tender with the last log when the blackness of night fell upon them. Tom paused for an instant bewildered. They had plunged into the tunnel. The scene around him was illuminated by the flickering tongues of flame which lapped up the end of the log. He stumbled over the wood in the tender, and handed the log to Shadrack. Through the hole in the box-car he saw the men working at the fire. Several were bending over it, fanning, while others hurried back and forth in the dull glow bringing fuel. One man was breaking the walls of the car with the iron bar, throwing the boards back as he pounded and wrenched them loose. Then, suddenly, the blaze increased and the car was filled with smoke. Flames leaped several feet in the air, mounting high and higher until they spread out against the roof of the car. "More logs, Tom." Tom recognized Shadrack's voice. He passed log after log back. The train emerged from the tunnel. The car was leaving a trail of smoke behind it; flames were darting from the side doors and flowing back against the walls. Several of the men climbed into the tender, wiping their eyes and coughing. More followed them until the tender seemed overflowing. "All out, I guess," said Ross. "Whew! that's a hot fire." "Where's Shadrack?" demanded Tom. They glanced about from one to another. Shadrack was not among them. Tom jumped up to the edge of the tender and let himself down into the freight car. "Shadrack!" he called; then louder, "Shadrack! Shadrack!" There was no answer. The dense smoke choked and blinded him. "Shadrack!" He ran down the car, holding his breath and dodging the flames. "Shadrack!" "Here!" "Where?" "Outside." Tom swung out around the end of the car and found Shadrack on the ladder, climbing and fighting the waves of smoke which drifted back upon him, enveloping him, from the side door. He was dragging himself wearily from one rung to another. "Can you get up?" Tom asked. Shadrack gasped and shook his head. "Hold on tight! Just hold there!"
