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.”

“But if another gale was to spring up, and there is every chance of that, the flag might be blown to pieces, or the flagstaff itself carried away,” observed the boatswain. “If you think fit, therefore, Mr Shafto, I’ll remain here with one or two of the men; and, depend on it, we will keep a bright look-out for passing vessels, so that we need only hoist our flag should one come near enough to see it.”

“We can ill spare you at the camp, Bollard,” said Harry; “and if you remain here you will require shelter and food. This hill is a bleak place, and if we could not get to you with a supply of provisions, you would run the risk of starving.”

“As to shelter, we have our axes, and we might easily put up a hut; and for the matter of food, if we are hard-pressed, we can make our way overland to the settlement; it cannot be much more than five or six miles.”

As the boatswain was so anxious to remain, Harry at last consented to his proposal.

“We must put you up a hut, however, before we return to the settlement,” he observed; “and after we have had dinner we will set to work about it.”

There was a wood at some little distance; and, as soon as the meal was over, all hands repaired there to cut timber for the proposed hut. They worked away very hard, Harry and the midshipmen labouring as well as the rest. As soon as several trees were felled, Harry, leaving Bollard and two of the men to cut more, with the rest of the party carried them up the hill. They had then to dig the foundation of the hut. While this was doing, Willy and Peter collected a supply of grass from the hillside.
