The more we neared the south the more these floating islands increased both in number and importance. At 60° lat. every pass had disappeared. But, seeking carefully, Captain Nemo soon found a narrow opening, through which he boldly slipped, knowing, however, that it would close behind him. Thus, guided by this clever hand, the Nautilus passed through all the ice with a precision which quite charmed Conseil; icebergs or mountains, ice-fields or smooth plains, seeming to have no limits, drift-ice or floating ice-packs, plains broken up, called palchs when they are circular, and streams when they are made up of long strips. The temperature was very low; the thermometer exposed to the air marked 2 deg. or 3° below zero, but we were warmly clad with fur, at the expense of the sea-bear and seal. The interior of the Nautilus, warmed regularly by its electric apparatus, defied the most intense cold. Besides, it would only have been necessary to go some yards beneath the waves to find a more bearable temperature. Two months earlier we should have had perpetual daylight in these latitudes; but already we had had three or four hours of night, and by and by there would be six months of darkness in these circumpolar regions. On the 15th of March we were in the latitude of New Shetland and South Orkney.
