One was a tiger and the other a black seal. Now they separated, now they dashed at each other, just like savage dogs, not uttering the slightest sound all the time. Now they sank below the surface, now rose again, tearing away at each other as before. "I shouldn't be surprised that one of them was the big fellow you called Tippo Sahib, who attacked you the other day, Paul," said Willy. "May be, sir," answered Lizard. "But see, there's another on the rocks. That's master Tippo, I suspect. He looks as if he was watching for us, and I shouldn't be surprised if he was to give chase." Willy laughed at the notion; but directly afterwards the old lion plunged into the water, and his snout was seen within a few seconds rising close to the oars. Harry ordered the men to pull on, as he did not wish to expend any shot on the animal. Tippo, however, seizing the blade of Paul's oar, held it so tightly that he nearly hauled it out of his hands. Not till he had received several blows on the nose from the other oars would he let go. "Why, he has nearly bitten my oar in two," cried Paul. "Better that than your leg," observed Willy. "That's Tippo; I have no doubt about him," cried Paul. "He means mischief." The sea-lion, however, was kept at bay by the oars, while the boatswain stood up in the stern with a club, ready to give him a blow should he come nearer. After swimming round the boat for some time, he seemed to consider that he could gain nothing by a battle with the four-legged strange creature, as he doubtless considered the boat, and so leisurely swam back to the rocks he had left, up which he scrambled, and sat watching the cutter as she continued her course along the shore. A breeze at last sprang up, and sail being set she ran down to the mouth of the harbour. On the northern shore, near the eastern entrance, was a point rising for a hundred feet or more above the water. Here the party landed, and Harry and the boatswain agreed that it was the best station on which their flagstaff could be planted. From its summit they could look over the whole of the southern island; while the flag would be visible far out at sea, beyond the western entrance of the harbour. The flagstaff was accordingly landed, and as all hands were required to set it up, and the boat could not be left alone, she was hauled up on the beach. But as they had only wooden spades to work with, some time was occupied in digging the hole in which to plant the flagstaff. It was at length got up, and stayed by four shrouds. The flag was hoisted and flew out to the breeze. "That will show that some one is not far off," observed Mr Bollard. "But should a vessel send her boat on shore, the people may not know where to find us." "I have been thinking of that," said Harry, "and will leave a bottle with a paper in it directing them to the settlement."
