“It is the Minerva coral island,” Ben heard the captain observe to Mr Charlton, after he and the master had been looking over the chart.

As the ship rose and fell with the swell of the ocean, the trees were now seen and now again lost sight of alternately for some time; this had a very curious effect. As the frigate drew near, a white sandy beach was seen, and, higher up, a belt of land of a light clay colour, on which grew a few shrubs not more than fifteen feet high, above which towered the pandanus, cocoa-nut, and palms. The whole island was about ten miles long, and a mile and a half wide, the centre part being occupied by a lagoon, or lake, of smooth deeply blue water, thus leaving a belt of land not more than six hundred feet across. This lagoon had no opening or entrance to it, but Ben heard that the lagoons of most of the coral islands have a communication with the sea, so that boats and canoes can enter. Outside the island, at some little distance, rose a second or outer reef, over which the sea flowed at high water. This served in heavy gales, when the waves rolled in furious to break their force, and to protect the shore over which they might otherwise have swept, carrying away the trees and shrubs which made it a fit habitation for man.

Mr Martin gave Ben and Tom an account of the way these coral islands are formed. “Coral, you will understands is made by very small sea insects, who form it for their habitation,” he observed. “God has given them the instinct to build in certain ways and places, just, as if they knew what they were about, and that they were building up an island fit to be inhabited by human beings. They seem to choose the tops of rocks from one hundred to two hundred fathoms below the surface, for the foundation of their structure. They have toiled on for ages, placing storey upon storey, till the surface has been reached, when they have been compelled to cease; for out of the water, whence they draw their materials—their bricks and mortar, so to speak—they can do nothing. The outer edge breaks the force of the sea, but not altogether. Enough strength is exerted during storms to tear off the outer edge of the coral, and to throw it on the top of the wall. Seaweed and driftwood and dead fish are next thrown up on it, which, when they decay, form soil. Birds next come and rest on the island, and further enrich the soil. They bring seeds of grass and small shrubs at first, and afterwards of larger trees, which take root and spring up, and in their turn, when they decay, form more earth to nourish a larger species of trees, such as the tall palms, and cocoa-nut, and pandanus, which we have seen growing on them. The sandy beach is formed of the broken coral and shells, ground small by the constant action of the waves. I have heard that the lagoons are often very deep, so that the island is exactly like a circular wall built up from the bottom of the sea, or rather from a rock far down in it.”

Mr Martin promised the boys that he would tell them more about other islands which they were likely to visit another time. He had also with him some most interesting accounts of the progress which the missionaries had made among the heathen in those seas, which he promised also to give them.

People were seen on the shore, though no habitations were visible, and Captain Bertram wished to communicate with them. While the frigate was hove to, to leeward of the island, two boats were sent on shore under Mr Charlton’s command. Ben went in one of them. A native of Tahiti, called Tatai, had been shipped at Callao to act as interpreter, as without one very little intercourse could have been held with the natives. Ben had told him all about Ned, and how he hoped to find him on one of the islands they expected to visit Tatai said that he must not be too sanguine, as it was very like looking for a pearl in a bed of oysters, though there were great numbers of white men scattered about among the islands, and even living among the most savage natives. He promised, however, to make inquiries, and to help on his object as far as he had the power.

The boats had to coast along for some time before an entrance through the reef could be found. The sea dashed against the reef, and, curling over, fell back in a shower of spray. A boat striking it would have been instantly overwhelmed or dashed to pieces. The passage between the two walls of water which thus rose up on either side of the entrance was very narrow. It seemed indeed that the boats could not pass through without the oars touching the rocks. Mr Charlton, however, considered that the passage was practicable, so also did Tatai. Mr Charlton led, and as his boat was cautiously feeling its way, a smooth roller majestically approached the shore. “Give way, lads,” he cried. The boat glided on, the water broke with a thundering roar on the reef; but the boat, like an arrow, had shot through and was floating safely within the reef. The other boat immediately followed.

The natives from the shore had been watching these proceedings, and now gathered in considerable numbers on the beach. They were all armed with spears, and showed an evident dislike to holding intercourse with the white people. They nourished their spears, pointed them towards the boats, and made significant gestures for the intruders to depart. Still, as it was important to speak to the poor savages, Mr Charlton pulled towards a ledge of rocks which ran out from the shore, and with a basket full of presents, landed, accompanied by Tatai. The people ran towards him, threatening with their spears as before. He advanced as if to meet them, put down the presents, and then retreated. An old man, who wore a short petticoat of leaves fastened round his waist, and a pandanus leaf hung from his neck as a sign that he was a chief, was in front. He stopped, picked up the handkerchiefs, knives, and trinkets which formed the offering made to him, and, having handed them to his followers, rushed on, gesticulating furiously, towards the English officer. Tatai shouted out that the visitors came as friends, but the only reply he got was, “Go away, go away! we do not want you,” spoken in the native tongue.

This was not encouraging. Mr Charlton, however, was not to be defeated. Pulling off to a little distance from the shore, he consulted with Tatai. “If we land without arms and offer them food, that will show that we wish to be friends,” he said. Tatai agreed to this, and offered to accompany the lieutenant, provided the boat kept near enough to render them assistance if required.

Again the boat pulled in, and Mr Charlton told Ben that he might land with him, as the savages would see by a boy being of the party that no treachery could be intended. Again the boat touched the beach, at a spot where she could easily be shoved off, and, having deposited his sword and pistols and rifle in the boat, Mr Charlton with his two companions proceeded towards a group of natives who had been watching their proceedings. The natives, instead of coming towards them, seemed to be holding a consultation together. Mr Charlton and his companions, seeing this, sat down, and, taking the provisions out of the basket Ben carried, commenced eating. After a short time, placing the food on a flat rock, and retiring to a little distance, they made signs to the natives to come and eat.

The natives now without hesitation came down, led by their old chief, who took the lion’s share of the food, which he seemed to enjoy very much. When the old man had finished eating, Tatai addressed him. He no longer said, “go away,” but listened attentively. The interpreter told him that the English had come to his island as friends; that their only object was to do him good; that they had heard that certain wicked people in vessels had visited some of the islands in their seas, and carried off the natives to make slaves of them; and that, as the English did not like having people made slaves, they were seeking for those bad men to punish them.
