The latter, they found out later, was only aboard for a certain purpose, not one of the crew. While they noted the precision machinery for driving the boat, and saw the novel way in which the exhaust was deadened by being run through a large pipe through a sheathed channel in the hull, into a specially devised muffler which completely broke up the explosive force of the spent gases and silenced their noise, the chums marveled at the pains that had been taken to make a once innocent pleasure yacht into a craft suited for breaking its country’s laws. Nicky reiterated his wish that they could do something to bring the lawbreakers to justice, but Tom, again cautious, urged him not even to think of it just then.

His comrades stared at him; for the answer to their unspoken question, he pointed upward. Looking toward the tip of the short spar
