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.
