Some time passes, and at length Tony appears on the beach. We make signals that he must be brought off in a canoe. As he steps into the boat, stout-hearted fellow as he generally is, he sinks down, overcome with the terror he has been in. Several of the crew cry out that now we have got him back, we must hang the savages we have in our power in revenge for our shipmates who have been clubbed. The captain says that we are bound to let one go. I plead that all should be let go, that on the faith of this Tony was returned to us, and that it is both our duty, and wise as a Christian and civilised people, to show clemency to the savages. With difficulty, however, I prevail, and Bent tells the chiefs that they may order a canoe to come alongside, and may go free. They appear very much astonished, and doubtful whether we are in earnest. I watch their eyes when they fully understand that they are free to go. Savages though they may be, there is human sympathy between us; they are grateful for the way we have treated them; and I feel sure that we should be far safer on shore should we return, than if we had hanged them as proposed. "We are well quit of these savages," observes Golding, as we get free of the reefs, and stand out to sea. There is another group to the north of the Tongas called Samoa, or Navigators Islands. The people, Bent tells me, are very like those of the Tonga group. Of this Tonga group which we are leaving there are numerous islands--the first collection to the north, called the Haabai group, while further north is that of Vavau--all governed by different chiefs, who spend their time in fighting with each other. While I am on deck in charge of the watch that night I see a bright light burst forth to the north-east, rising out of the sea and reaching to the sky. There is a noise at the same time as if there was distant thunder. I fancy at first that some hapless ship has caught fire, and I send below to ask leave of the captain that we may steer towards her to pick up any of the crew who may have escaped. The captain bids me come and examine the chart, and I see several islands with burning mountains on them marked down. The fire we see proceeds undoubtedly from one of them--Koa, perhaps. The matter is settled by finding our deck covered with fine ashes fallen from the sky.
