“An army!” echoed Otto, “what do we want with an army? who have we to fight against?”

Little did Otto or Pauline think that at the very time they were conversing thus pleasantly on that beautiful islet, the presence of a friendly army was urgently required, for there in the bushes close behind them listening to every sentence, but understanding never a word, lay a group of tattooed and armed savages!

In the prosecution of evil designs, the nature of which was best known to themselves, these savages had arrived at Refuge Islands the night before. Instantly they became aware of the presence of the white men, and took measures to observe them closely without being themselves observed. Carrying their war-canoe over the reef in the dark, and launching it on the lagoon, they advanced as near to the settlement as possible, landed a small party on an islet, and then retired with the canoe. It was this party which lay in ambush so near to our little hero and heroine. They had been watching the settlers since daybreak, and were not a little surprised, as well as gratified, by the unexpected arrival of the little boat.

The savage who lay there grinning like a Cheshire cat, and peeping through the long grass not ten feet from where the brother and sister sat, was a huge man, tattooed all over, so that his face resembled carved mahogany, his most prominent feature being a great flat nose, with a blue spot on the point of it.

Suddenly Otto caught sight of the glitter of this man’s eyes and teeth.

Now, the power of self-restraint was a prominent feature in Otto’s character, at least in circumstances of danger, though in the matter of fun and mischief he was rather weak. No sign did Otto give of his discovery, although his heart seemed to jump into his mouth. He did not even check or alter the tone of his conversation, but he changed the subject with surprising abruptness. He had brought up one of the dinghy’s oars on his shoulder as a sort of plaything or vaulting-pole. Suddenly, asking Pauline if she had ever seen him balance an oar on his chin, he proceeded to perform the feat, much to her amusement. In doing so he turned his back completely on the savage in ambush, whose cattish grin increased as the boy staggered about.

But there was purpose in Otto’s staggering. He gradually lessened the distance between himself and the savage. When near enough for his purpose, he grasped the oar with both hands, wheeled sharply round, and brought the heavy handle of it down with such a whack on the bridge of the savage’s blue-spotted nose that he suddenly ceased to grin, and dropped his proboscis in the dust!

At the same instant, to the horror and surprise of the brother and sister, up sprang half a dozen hideous natives, who seized them, placed their black hands on their mouths, and bore them swiftly away. The war-canoe, putting off from its concealment, received the party along with the fallen leader, and made for the reef.

High on the cliffs of Big Island Dr John Marsh had been smilingly watching the proceedings of the queen and her brother in the dinghy. When he witnessed the last act of the play, however, the smile vanished. With a bound that would have done credit to a kangaroo, and a roar that would have shamed a lion, he sprang over the cliffs, ran towards the beach, and was followed—yelling—by all the men at hand—some armed, and some not. They leaped into the largest boat on the shore, put out the ten oars, bent to them with a will, and skimmed over the lagoon in fierce pursuit.

Soon the savages gained the reef, carried their canoe swiftly over, and launched on the open sea, cutting through the great rollers like a rocket or a fish-torpedo.
