Sam climbed up to the little platform on the right side of the gun, winking at his companions as he did so.
"What shall I do now?" he questioned, taking his place.
"Sight through the finder. I'll set the target going."
"Yes, I see it. I'm afraid that thing will make me seasick if I keep on looking at it," declared Hickey, looking up at the instructor.
"Attend to your practice!"
"Bang!"
Sam leaped up into the air. His head came into violent contact with the deck above him.
"Ouch!" yelled the red-headed boy, as he collapsed in a heap on the deck.
Sam had unwittingly pulled the trigger, firing the cap that bad been provided to explode the dotter, thus making the miniature target work the more realistic.
"Did something hit me? I—I thought the seven-inch had gone off," stammered the boy, pulling himself to his feet and rubbing his head where it had hit the ceiling.
