Brad did not take a moment to debate. Already the trucker was starting to pull away from the filling station.

“Come on,” he urged, bolting out the door.

The boys signaled the truck driver who halted just before he reached the main highway.

“Are you driving to Webster City?” Dan shouted.

“That’s right.”

“Will you give us a lift?”

“I sure will,” the trucker agreed heartily, opening the cab door. “Hop in, boys.”

As the truck rattled along the slippery road, Dan and Brad told the driver of their urgent reason for reaching the Gardiner Building.

“You’re making no mistake in thinking that creek will flood,” the trucker declared, putting on more speed. “Even if the stream isn’t clogged, she’s sure to go over her banks.”

To help the boys, the driver dropped them off directly in front of the Gardiner Building. Their shoes caked with mud, their wet hair still plastered down, the pair made a sorry appearance as they entered Mr. Silverton’s outer office.
