Reaching for each other's hands, they raced down the slope.
Halfway there they saw a warning blast of steam rise from the engine, followed by a whistle.
"They'll be pulling out in a minute now!" he gasped, increasing speed. "We've got to make it!—our only chance!"
"We will make it!" she sobbed through clenched teeth, meeting his pace.
Glancing over his shoulder, after another fifteen seconds, Kendrick saw that the disc was no longer visible. Since there was no vibration he realized with relief that it was now hidden behind the slope they were descending.
"Quick—push your button!" he said, pushing his own.
They came out of the influence of the invisibility rays, raced breathless on down the slope—gained the station platform just as the train was getting under way.
Helping the exhausted girl aboard, he mounted the steps himself, led her through the vestibule into its single passenger coach.
Dropping into a seat, they sat there panting as the train gathered speed.
