"They're firing at us!" cried Ned Newton.
"Guess there isn't much doubt of that!" was Tom Swift's grim rejoinder. "Are you hit?"
"No. Are you?"
"Not yet, but we both may be if this thing keeps up."
That the bombardment was going to keep up was evident a moment later when above the noise of the storm there were other shots and a second window was shattered.
"Come on!" cried Tom, and with a quick motion he shut off all lights on the House on Wheels, leaving it in gloom.
"What are you going to do?" asked Ned.
"Get off this seat. We're in too exposed a position here. They're trying to pick us off!"
"It sure seems so!" agreed Ned.
"Follow me before the next lightning flash, or they'll see us," called Tom into Ned's ear.
