Ralph, at a momentary cessation of operations, wiped the grime and perspiration from his baked face, to take a scan of the fire-swept area.

A railroad official had come up to the engine, hailed Griscom, and pointed directly into the heart of the flames to where, hemmed in a narrow runway between the walls of two smoking buildings, were four freight cars.

"They'll be gone in five minutes," he observed.

"I can reach them in two," announced Griscom tersely, setting his hand to the lever. "Get a good man to couple--our share won't miss. Let her go!"

A brakeman, winding a coat around his head like a hood, and keeping one end open, sprang to the cowcatcher, link and bar ready.

Ralph shuddered as they ran into the mouth of the lane. It was choked with smoke, burning cinders fell in showers on and under the cab.

"Shove in the coal--shove in the coal!" roared Griscom, eyes ahead, lever under a tensioned control. "Good for you!" he shouted to the nervy brakeman as there was a bump and a snap. "Reverse. We've made it!"

A sweep of flame wreathed the pilot. The air was suffocating. Ralph staggered at his work. As the locomotive reversed and drew quickly out of that dangerous vortex of flame, the boy noticed that the last of the four cars was blazing at the roof.

"Just in time," he heard old Griscom chuckle. "Hot? Whew!"

He set the wheels whirling on the fast backward spin, and stuck his head out of the window to shout encouragingly to the huddled, smoking hero on the pilot.
