“Now for it!” cried the fun-loving Rover, and without hesitation struck a match and applied the light to the fuse. Instantly the latter began to fizz, and all of the boys took to their heels.

Bang! [It was a tremendous explosion], much louder than any of the boys had anticipated, and it fairly made the windows of the various school buildings rattle. Looking, they saw not one spurt of flames, but a dozen or more shooting in various directions.
