"Lets have a try," Chester shouted back.
The boys left their places in the line, and approached the tank. Hal climbed inside first. Chester followed him.
He bent down and tinkered with the engine. It was not the first time the lads had been inside a tank, so they were fairly familiar with the mechanism.
After some tinkering, Hal gave an exclamation of satisfaction.
"She'll go now," he cried.
He opened the throttle, and the machine moved forward. Hal brought it to a stop almost immediately.
"We can't man all these guns," he cried. "We must have a crew."
Chester alighted and approached a captain of infantry who was passing at that moment.
"We want a crew for this tank!" he exclaimed. "Can you give me four men?"
"Take your pick," the captain called back.
