Moored to a stranded iceberg about a mile from winter quarters, the Nimrod was sheltered from blizzards.

DISCOVERERS OF THE SOUTH MAGNETIC POLE

Part of Shackleton’s expedition reached for the first time the South Magnetic Pole—that is, where the south part of the compass needle points. Those in the picture, reading from left to right, are Dr. Mackay, Professor David, and Douglas Mawson.

The record of Antarctic explo­ra­tion from 1772 to date may be divided into two periods; the first from 1772 to 1898 and 1899, a period of summer voyages only, the work carried on entirely by ships, with no land or sledge work, and no attempt to winter in that region. During this period, though other nations, notably the United States and France, took part in the work, the work of Great Britain was so pronouncedly preponderant as to more than equal all the others combined. The second period is from 1899 to date, and is the period of overland explo­ra­tion with sledges. In this period, as in the last period of Arctic explo­ra­tion, three men, Scott, Shackleton, and Amundsen, each having for his object the attainment of the South Pole, pushed so far beyond all predecessors as to be in a class by themselves, two of them, Amundsen and Scott, actually reaching the Pole.
