“We know why you have come. Not long ago a vessel appeared and carried off a number of our people, and you will try to do the same; but we will prevent you.”

Our interpreter tried to explain that our object was simply to trade honestly; that if they had any cocoanut oil, we would give them a fair price for it.

“We will not trust you,” was the answer. “Go away! Go away!”

As we saw several of the people clothed in shirts, and some even in trousers, we had no doubt that a missionary was among them, though we could not distinguish him from the rest. It was, however, evident that they had been visited by a kidnapping vessel, and some of their people, probably Christians, had been carried off into slavery. Finding, notwithstanding all our protestations that we were honest traders, that the natives would not allow us to land, Charlie and I agreed that it would be folly to attempt doing so, and therefore returned to the vessel.

Soon after this we came off another island totally different to any we had before visited, being formed of corals that had been uplifted to the height of upwards of two hundred feet, and surrounded by cliffs worn into caverns. As no natives appeared, Harry did not wish to lose time by landing.

The islands of the Pacific present a great variety of forms, although the larger number are either partly or entirely surrounded by coral reefs. These reefs, however, vary in construction; some are called encircling reefs, when they appear at a distance from the shore, and a lagoon intervenes; others are called fringing reefs, which are joined to the land, and extend out from it without any lagoon. Others are denominated lagoon islands, when the reef itself, raised above the surface of the ocean, forms the land generally in a circular shape, and surrounds a lake or lagoon, which has sometimes a passage to the sea, and at others is completely closed. Then there are atoll islands; these rise within a large encircling reef, which is seldom perfect, having passages here and there through it. Sometimes there are elevations on the reef itself, forming islands; but frequently the reef is a wash with the sea. Besides these, there are the great barrier reefs which extend along the larger part of the eastern coast of Australia, part of New Guinea, and New Caledonia. Some of these are several hundred miles in extent. These countless reefs are all formed by the coral insect. The difference of their appearance is owing to various causes: some by the subsidence of the land; others by its elevation through volcanic agency. The encircling reefs have been produced by the subsidence of the land; they were originally fringing reefs, having been attached to the coastline of the country or islands. As the land sank, the insects went on building one generation above another; but they can only work in a certain depth of water—below which they die; thus a wall has been built up on the foundations formed by the original workers, who constructed a fringing reef. After a time, the last architects have died, storms have thrown up pieces of coral shells and other débris on the top of the wall, birds have brought seeds of plants, the ocean has washed cocoanuts and other palm seeds on to the top: thus vegetation has been commenced, and finally groves of trees and shrubs have grown up.

The barrier reefs have been formed in the same way. Where no vegetation appears, the has probably sunk as rapidly as the creatures have built, and the sea has continued to wash over it. Other groups have been formed by the violent elevation of the land when the barrier reef has been broken into and wide gaps have appeared.

The last island we visited, surrounded by high cliffs, must have been formed by the sudden upheaval of the earth beneath it, so that the whole mass of coral was lifted above water. Such has been the origin of a considerable number of islands. The most beautiful and picturesque, like Tahiti and others in that group, owe their present shape to the subsidence to the earth, they being merely the summits of mountain ranges, probably of some vast continent, of which the lower land has been submerged. The gaps or openings in the encircling reefs are always found opposite to a river or stream. The coral insect can only build in pure salt water; the fresh water running out from the river has, therefore, prevented its upward progress; thus a gap in the wall has been formed serving as a safe entrance to the inner lagoon. Knowing these facts, it was easy to decide to which class the islands and reefs we passed belonged. There was always, therefore, matter of interest before us.

Volcanic action has been the agent of many of the islands to the westward, where several still active volcanoes exist. Many of those in that direction are clothed with the richest vegetation. They are inhabited by dark-skinned races; still the most savage among those of the Pacific, such as the New Hebrides, Santa Cruz, Solomon Islands, and New Ireland, to the eastward of New Guinea. They produce the finest sandal-wood, and Harry determined to visit some of them, in order to obtain a supply before returning home. He had, however, settled to call first, as I have said, at the islands, where he hoped to be able to purchase palm-oil.

The first we reached after this was very similar to those already described. The natives, as we appeared, came off to the schooner in their canoes, and invited us to enter a secure harbour into which they offered to pilot her. Several of those who boarded us were dressed in shirts, and one of them spoke a sufficient amount of English to make himself understood. He said that two native missionaries were settled on the island, and that all the inhabitants were Christians. They had also, he added, a good quantity of palm-oil, of which they would be glad to dispose. Harry, therefore, without hesitation, accepted their invitation, and we brought up within the outer reef, at no great distance from the shore.
