The time had passed uneventfully with the three young telegraphers, the end of the second week finding Alex and Jack together with the construction-train at the rail-head, and Wilson Jennings back at the temporary station and material-sidings at the viaduct.

Perhaps the last few days had passed least interestingly with Wilson, alone in his little box-car station, not far from the old river-bed. Saturday had seemed particularly slow, for some reason, and shortly after 8 o’clock Wilson threw aside a book he had been reading, and catching up his hat, made for the door, for a brief stroll, previous to retiring.

The moon was momentarily showing through a break in the cloudy sky, and looking to the west, Wilson was somewhat surprised to discover the figures of two men approaching. When as he watched they reached the first of a train of tie-cars, and leaving the rails, continued forward in the shadows, Wilson stepped back, in disquiet.

The strangers came opposite, and paused, looking toward the station window and speaking in subdued voices. Convinced that something was afoot, the young operator turned quickly, and stooping low, that his shadow might not be seen on the window, crept to the little instrument table and reached for the telegraph key. He opened, and pressed it down. The sounder did not respond. He tried again, adjusting the relay, and turned about in genuine alarm.

The wire had been cut! Some mischief was surely afoot.

From without came the crunch of stealthy footsteps. Springing to his bunk, Wilson secured his revolver and belt—the same taken from the would-be bullion thief he had captured at Bonepile—and stealing to the rear door, slipped out and to the ground just as the strangers approached the opposite side of the little car-depot.

The car was raised on a foundation of ties, and as the two men entered, Wilson crept beneath.

“No one here,” said a gruff voice. “Say, do you s’pose he saw us, and sneaked?”

“Like as not. I told you to keep to the rails and come straight up,” chided the other.

“Perhaps he will come back. We’re in charge of the station anyway. That was the real thing.”
