There was a little clicking sound, as the youth moved some gear wheel on his gun. Then there came a faint crackling noise, like some distant wireless apparatus beginning to flash a message through space.
Suddenly a little ball of purplish light shot through the darkness and sped forward like some miniature meteor. It shed a curious illuminating glow all about, and the ground, and the objects on it were brought into relief as by a lightning flash.
An instant later the light increased in intensity, and seemed to burst like some piece of aerial fireworks. There was a bright glare, in which Ned and the others could see the various buildings about the shed. They could see each other’s faces, and they looked pale and ghastly in the queer glow. They could see the box, brought into bold relief, where Ned and the engineer had placed it.
Then, before the light had died away, they witnessed a curious sight. The heavy wooden box seemed to dissolve, to collapse and to crumple up like one of paper, and ere the last rays of the illuminating bullet faded, the watchers saw the splinters of wood fall back with a clatter in a little heap on the spot where the dry-goods case had been.
A silence followed, and the darkness was all the blacker by contrast with the intense light. At length Tom spoke, and he could not keep from his voice a note of triumph.
“Well, did I do it?” he asked.
“You sure did!” exclaimed Ned heartily.
“Fine!” cried Mr. Swift.
“Golly! I wouldn’t gib much fo’ de hide ob any burglar what comed around heah!” muttered Eradicate Sampson. “Dat box am knocked clean into nuffiness, Massa Tom.”
“That’s what I wanted to do,” explained the lad. “And I guess this will end the test for tonight.”
