Boom! Boom!
Two more explosions rent the air, both much louder than the first. The very ground seemed to be shaken by the concussion.
“Say, that sounds like a warship!”
“No warships around here,” was the answer.
“Maybe it’s a German Zeppelin!”
“Gee! do you suppose the Germans have come over here to bombard us?”
Boom! Boom! Boom!
Several more explosions came now close upon the others, each explosion heavier than those which had gone before. The ground all around seemed to tremble, and those who were still in the grandstand cried out in alarm.
“The grandstand is going down! Everybody jump for his life!”
“Look! Look!” was the sudden cry from Jack Rover, and he pointed to a place on the opposite shore of Clearwater Lake. A dense volume of smoke was rolling skyward. Then came another tremendous explosion, and a mass of wreckage could be seen to be lifted skyward.
