"Something wrong at limits--everything wrong here!" panted Ralph, his heart suddenly beating like a trip-hammer. "What shall I do?"

He shot a glance at the nearing headlight. Relying on limits signals, evidently expecting the long freight siding, in the darkness and storm taking no note of outside switches, and behind time, those in charge of the through freight had nearly full speed set.

Ralph felt the blood leave his face. Through his mind in rapid sequence ran the plat of switches at the depot yards.

"No. 6, or destruction!" he gasped. "I've got to make the choice. It's the only track open. Open--no!" he added, with a new thrill of apprehension, "but--there's no other way."

He pulled the lever that would send the through freight down track 6. Then a wild tumult seized him. He darted for the trap. He almost fell the length of the iron-runged ladder. Then Ralph sprang through the doorway and tore across the tracks.

Track 6 was not empty. At its bumpered end were three old empty freights. Ralph, however, counted their destruction as of little consequence as compared with a crash on track 7 into the theatre car, holding perhaps a dozen sleeping inmates. He had made an independent choice. He had saved them. Now, if possible, to save the freight train from a collision!

As he passed the switch he tore from a pivot the signal lantern resting there. Carrying it in his arms, he dashed forward diagonally to meet the rushing freight. Extending its red slide, he waved frantically up and down and across, yelling at the top of his voice.

The locomotive of the through freight whizzed by him. In the blur of rain and radiance Ralph fancied a grizzled head was poked out through the cab window. At all events he caught the quick, harsh whistle of the air brakes. A jolt shook the long freights. His signal had been observed.

Following the locomotive with his eye, Ralph saw, three hundred yards further on, a figure suddenly cleave the air. The engineer had put on full stop brakes and had jumped.

The train was slowing up. Would she stop in time? Car after car whirled by. Then crash! Far ahead, the last car past him, Ralph caught the ominous sound, and shivered and gasped.
