forward with a jump.

The German rifles spat fire. Revolvers appeared simultaneously in the
hands of Chester and McKenzie. Both sprang to their feet, and, each
holding to a side of the machine, they returned the fire, as Hal bent
over the wheel.

"Crack! Crack!"

Chester and McKenzie fired together.

In spite of the movement of the car their aim was true, and two German
soldiers fell in their tracks. Stubbs still kept his seat.

The automobile, with its first lurch forward, had mowed down several of
the enemy, and now dashed forward with a clear path to the Dutch
border.

Behind, at command from the German officer, the troopers, still upon
their feet, fell to their knees, and, taking deliberate aim at the
rapidly moving car, fired.

There was an explosion from the automobile. The car jumped crazily.
Chester, still standing, revolver in hand, was flung violently into his
seat, but McKenzie was not so fortunate. He toppled from the car head
foremost.

One of the German bullets had punctured a rear tire. Hal brought the
machine to a stop.
