the boxes and barrels. They were glancing about with eager eyes. Tom switched on an electric light, and, the instant he did so, he was aware of a movement in a little space formed by one box which was placed on top of two others. The lad saw a dark figure moving, as if to get farther out of sight.
"I've got him!" cried Tom, making a dive for the shadow.
A moment later the young inventor was bowled over, as a dark figure leaped over his head.
"Catch him, Mr. Damon!" he cried.
"Bless my hatband! I—I" Mr. Damon's voice ended in a grunt. He, too, had been knocked down by the fleeing man.
"Look out, Mr. Jenks!" cried Tom, to warn those on guard at the door of the storeroom.
There was the report of a gun, some excited shouts, and when Tom could scramble to his feet, and rush out, he beheld Mr. Parker calmly sitting on a struggling man, while Mr. Jenks held a gun, that was still smoking.
"We caught him!" cried the scientist.
"Anybody hurt?" asked Tom, anxiously.
"No, I knocked up his gun as he fired," explained Mr. Jenks. "Where are the ropes, Tom?"
