Tom's Tank

"What was it?" gasped Mary, and, to her surprise, she found herself close to Ned, clutching his arm.

"I have an idea, but I'd rather let Tom tell you," he answered.

"But where's it going?" asked Mr. Nestor. "What in the world does Tom Swift mean by inviting us out here to witness a test, and then nearly running us down under a Juggernaut?"

"Oh, there must be some mistake, I'm sure," returned his daughter. "Tom didn't intend this."

"But, bless my insurance policy, look at that thing go! What in the world is it?" cried Mr. Damon.

The "thing" was certainly going. It had careened from the road, tilted itself down into a ditch and gone on across the fields, lights shooting from it in eccentric fashion.

"Maybe we'd better take after it," suggested Mr. Nestor. "If Tom is—"

"There, it's stopping!" cried Ned. "Come on!"

He sprang from the automobile, helped Mary to get out, and then the two, followed by Mr. Damon and Mr. Nestor, made their way across the fields toward the big object where it had come to a stop, the rumbling and roaring ceasing.
