Robin was of opinion that they should trust the strangers and go forward. Stumps agreed with him, but Sam thought with Slagg. Their indecision, however, was cut short by a most startling occurrence.

While they were yet whispering together, the sound of voices was heard in the distance. Our castaways at once sank flatter into the grass, and became mute.

In a few minutes the voices drew gradually nearer, until they were quite close to the alarmed watchers. Suddenly, from among the bushes on the other side of an open space just in front of them, there issued a band of men, walking in single file. Their appearance might have aroused grave anxiety in the most unsuspecting breast, for, besides possessing faces in which the effects of dissipation and evil passions were plainly stamped, they were armed—as the saying is—to the teeth, with short swords, cavalry pistols, and carbines. They were dressed in varied Eastern costume, and appeared to be of Malay origin, though some bore closer resemblance to the Chinese.

The man who marched in advance—evidently the leader of the band—was unusually tall and powerful, with a remarkably stern, but not altogether forbidding, countenance.

“Pirates!” whispered Slagg.

“Looks like them, but may be smugglers,” replied Sam in the same cautious tone.

Even Robin’s unsuspecting and inexperienced nature would not permit him to believe that they were honest traders. Had any doubts on the subject lingered in their minds, these would have been effectually cleared away by the scenes which immediately followed.

While the pirates were still at some distance from the shore, sudden shouts and yells came from the vessel, which had, up to that time, been lying so peacefully at anchor, and it was at once clear that a furious hand-to-hand fight was taking place upon her deck.

“It must be the poor slaves who have risen,” whispered Sam.

The pirates had drawn their swords and pistols at the first sound of the fight, and rushed to the rescue. They well knew that, while they had been on shore, the unfortunate captives chained in the vessel’s hold had succeeded in freeing themselves, and were endeavouring to overcome the few men left to guard them.
