Lockwood’s coast-line extends for 110 miles of longitude, or altogether 150 miles. It consists of a succession of high, rocky, and precipitous promontories, with intervening inlets, and a mass of snow-clad mountains inland. Along the shore was what was called a tidal crack, varying in width, supposed to be caused by the motion of the polar pack. Lieutenant Greely rightly concluded from the regularity of the surface in the fjords or inlets, that this was really the north coast of Greenland, and not a separate land as later alleged by Peary. Greely himself started on an expedition inland on June 26th, and this journey, combined with a shorter one in the spring, resulted in the discovery of an extensive lake, and enabled him to obtain a clear idea of this part of the great island, his furthest point being 175 miles from Conger. A number of Eskimo bone implements and remains of sledges, of considerable antiquity, were found and brought back. But now began the first hint of the misfortunes that were to befall them. The _Proteus_, the relief vessel which was to bring the expedition home, was anxiously expected but never arrived, and a second winter had therefore to be faced. On April 25th, 1883, Lieutenant Lockwood started for a month’s exploration westward. He succeeded in crossing the island to a fjord on the west coast to which he gave the name of Greely, and down this he and Sergeant Brainard travelled for 25 miles. To the south of the fjord the country appeared to be covered by an immense ice-cap with an unbroken series of cliffs from 125 to 200 feet in height.
