Passengers were pouring from the other cars, their terrified cries drowned by the grinding roar of the onrushing torrent. The wall of water moved with incredible speed. It tore into the railroad yard, shattering a tool house and a coal dock. It roared on, sweeping a row of empty box cars into its maw.

Spurred by the sight, Penny and Louise tried to leap the ditch. They fell far short and both plunged into the boiling water up to their arm pits.

Penny’s feet anchored solidly. With a gigantic shove, she helped Louise to safety. By swimming with the current she then reached shore a few yards farther down the railroad right of way.

“Run!” she shouted to the bewildered, bedraggled Louise. “Up the hill!”

Scrambling over the muddy edge of the ditch, she raced after her chum for higher ground. Just then the wall of water swept into the siding. As the train was struck it seemed to shudder from the terrific impact, then slowly settled on its side.

“Horrible!” Louise shuddered. “Some of the passengers may have been trapped in there!”

“Most of them escaped,” Penny gasped. “There goes the water tower!”

A building borne by the flood, rammed into the ironwork of the big dripping tower. It crumpled, falling with a great, shuddering splash.

With the back-wash of the flood sloshing against their knees, the girls raced for high ground. Reaching a point midway up the hill where other passengers had paused, they turned to glance below. Yellow, angry water, rising easily ten feet, flowed over the railroad right of way.

With unbelievable speed the flood rolled on. In one angry gulp it reached a long freight train farther down the track. The caboose and a string of coal cars were lifted and hurled. Strangely, the coal tender and engine which had been detached, remained on the rails.
