This, then, was the reason why Captain Len Guy refused to take passengers on board his ship, and why he had told me that his routes never were certain; he was always hoping that an opportunity for venturing into the sea of ice might arise. Who could tell indeed, whether he would not have sailed for the south at once without putting in at Tristan d'Acunha, if he had not wanted water? After what I had said before I went on board the _Halbrane_, I should have had no right to insist on his proceeding to the island for the sole purpose of putting me ashore. But a supply of water was indispensable, and besides, it might be possible there to put the schooner in a condition to contend with the icebergs and gain the open sea--since open it was beyond the eighty-second parallel---in fact to attempt what Lieutenant Wilkes of the American Navy was then attempting. The navigators knew at this period, that from the middle of November to the beginning of March was the limit during which some success might be looked for. The temperature is more bearable then, storms are less frequent, the icebergs break loose from the mass, the ice wall has holes in it, and perpetual day reigns in that distant region. Tristan d'Acunha lies to the south of the zone of the regular south-west winds. Its climate is mild and moist. The prevailing winds are west and north-west, and, during the winter--August and September--south. The island was inhabited, from 1811, by American whale fishers. After them, English soldiers were installed there to watch the St. Helena seas, and these remained until after the death of Napoleon, in 1821. Several years later the group of islands populated by Americans and Dutchmen from the Cape acknowledged the suzerainty of Great Britain, but this was not so in 1839. My personal observation at that date convinced me that the possession of Tristan d'Acunha was not worth disputing. In the sixteenth century the islands were called the Land of Life. On the 5th of September, in the morning, the towering volcano of the chief island was signalled; a huge snow-covered mass, whose crater formed the basin of a small lake. Next day, on our approach, we could distinguish a vast heaped-up lava field. At this distance the surface of the water was striped with gigantic seaweeds, vegetable ropes, varying in length from six hundred to twelve hundred feet, and as thick as a wine barrel.
