“Looks like we would run alongside in less than five minutes, sir,” observed George, trying to steady his voice, but hardly succeeding, for his nerves were tingling in a manner he had seldom if ever experienced before.

“Keep just a little to the left, then,” answered the agent. “And watch out, for it is barely possible they may try to foul us at the last, hoping to escape in the confusion.”

Jack was changing his mind now about that same thing. He had an idea that perhaps Clarence had played a trick on the men who held him in custody; he may not have let out all the speed of which the Flash was capable. Besides, now that the race seemed virtually over, and the Wireless had proven the superior why should he want to bring about a collision that would wreck both boats, as well as endanger the lives of all the occupants?

“Steady, George, steady!” Jack cautioned, as he thought he saw a slight change in the course taken by the boat ahead.

“Duck down, boys; he’s going to try and scare us by firing!” suddenly said the keen-eyed government agent.

Even George managed to partly drop, so as to be shielded by the forward deck. And that the revenue man had guessed correctly was made evident when there broke out the sharp report of a revolver. Jack even believed he could hear the peculiar whine of the flying bullet as it passed over the boat.

“Stay where you are!” cried the agent; “that was only one. He’s got a few more of the same kind to follow!”

There came other shots in rapid succession. Really, it would not be surprising if George lost his head under such circumstances, for usually it takes a veteran to preserve his coolness under fire. But, singular to state, the nervous one of the motor boys now proved that he could shut his teeth together and hold on tenaciously with bulldog courage.

The Wireless may have wavered just a little, but still kept swiftly on, diminishing the narrow lead of her rival with constant rapidity and steadiness.

“That’s all!” called the revenue man, as the sixth shot sounded; and every one felt a perceptible thud, telling that this time the desperate smuggler had lowered his aim, and that the bullet had struck the boat somewhere. “And as it’s a poor rule that won’t work both ways, perhaps I can have a little better luck in scaring some one. Watch out, George, and be ready to stop short if he does!”
