CHAPTER II
THE BELIEF IN IMMORTALITY AMONG THE TONGANS
§ 1. The Tonga or Friendly Islands
The Tonga or Friendly Islands form an archipelago of about a hundred small islands situated in the South Pacific, between 18° and 22° South latitude and between 173° and 176° East longitude. The archipelago falls into three groups of islands, which lie roughly north and south of each other. The southern is the Tonga group, the central is the Haabai or Haapai group, and the northern is the Vavau group. In the southern group the principal islands are Tongataboo and Eua; in the central group, Namuka and Lifuka (Lefooga); in the northern group, Vavau. The largest island of the archipelago, Tongataboo, is about twenty-two miles long by eight miles wide; next to it in importance are Vavau and Eua, and there are seven or eight other islands not less than five miles in length. The rest are mere islets. Most of the islands are surrounded by dangerous coral reefs, and though the soil is deep and very fertile, there is a great lack of flowing water; running streams are almost unknown. Most of the islands consist of coral and are very low; the highest point of Tongataboo is only about sixty feet above the level of the sea.[1] However, some of the islands are lofty and of volcanic formation. When Captain Cook visited the islands in 1773 and 1777 there was apparently only one active volcano in the archipelago; it was situated in the small island of Tufoa, which lies to the west of Namuka. Cook saw the island smoking at the distance of ten leagues, and was told by the natives that it had never ceased smoking in their memory, nor had they any tradition of its inactivity.[2] In the hundred and fifty years which have elapsed since Cook's time volcanic action has greatly increased in the archipelago. A considerable eruption took place at Tufoa in 1885: the small but lofty island of Kao (5000 feet high) has repeatedly been in eruption: the once fertile and populous island of Amargura, or Funua-lai, in about 18° South latitude, was suddenly devastated in 1846 or 1847 by a terrific eruption, which reduced it to a huge mass of lava and burnt sand, without a leaf or blade of grass of any kind. Warned by violent earthquakes, which preceded the explosion, the inhabitants escaped in time to Vavau. The roar of the volcano was heard one hundred and thirty miles off; and an American ship sailed through a shower of ashes, rolling like great volumes of smoke, for forty miles. For months afterwards the glare of the tremendous fires was visible night after night in the island of Vavau, situated forty miles away.[3] Another dreadful eruption occurred on the 24th of June 1853, in Niua Foöu, an island about two hundred miles to the north-north-west of Funua-lai. The entire island seems to be the circular ridge of an ancient and vast volcano, of which the crater is occupied by a lake of clear calm water. On the occasion in question the earth was rent in the centre of a native village; the flames of a new volcano burst forth from the fissure, belching a sea of molten lava, under which ten miles of country, once covered with the richest verdure, have been encased in solid rock, averaging from eight to fifteen feet in thickness. The lake boiled like a cauldron, and long after the more powerful action of the volcano had ceased, the waters of the lake were often rent by tongues of flame, which shot up from them as well as from the clefts in the surrounding precipices.[4] In the island of Late, lying to the west of Vavau, a new volcano broke out with great violence in 1854; the roar of the volcano was heard at Lifuka, fifty miles away; the immense pillar of smoke was visible by day and the fire by night. The central portion of one side of the mountain (about 2500 feet high) was completely blown out by the explosion.[5]
But not only have new volcanoes appeared or long extinct volcanoes resumed their activity within the last century in the existing islands, new islands have been formed by volcanic action. One such island, emitting volumes of fire, smoke, and steam, issued from the surface of the sea, and was discovered by the missionary ship John Wesley in August 1857; its appearance had been heralded some years before by a strange agitation of the sea and by fire and smoke ascending from the water. This new volcanic island lies about midway between the two other volcanic islands of Tufoa and Late.[6] A third new volcanic island seems to have been formed to the south of Tufoa in 1886.[7] Another new island was thrown up from the sea about the beginning of the twentieth century; it was partly washed away again, but has again materially increased in size.[8] It is noteworthy that the volcanoes, new or old, all occur in a line running roughly north and south at a considerable distance to the west of, but parallel to, the main body of the Tongan archipelago. They clearly indicate the existence of submarine volcanic action on a great scale. Even in the coralline islands traces of volcanic agency have come to light in the shape of pumice-stones, which have been dug out of the solid coral rock at considerable depths.[9] In the lofty island of Eua an extensive dyke of basalt is found inland underlying the coral formation.[10]
