Then came James Ross, who in 1818 sailed all around the shores of Baffin's Bay, and corrected the errors on the charts of his predecessors.

Finally, in 1819 and 1820, the famous Parry made his way into Lancaster Sound. In spite of numberless difficulties he reached Melville Island, and won the prize of five thousand pounds offered by act of Parliament to the English sailors who should cross the meridian at a latitude higher than the seventy-seventh parallel.[*]

In 1826, Beechey touched at Chamisso Island; James Ross wintered, from 1829 to 1833, in Prince Regent's Inlet, and, among other important services, discovered the magnetic pole.

During this time Franklin, by a land-journey, defined the northern coast of America, from Mackenzie River to Turnagain Point; Captain Back followed the same route from 1823 to 1835; and these explorations were completed in 1839 by Dease, Simpson, and Dr. Rae.

At last, Sir John Franklin, anxious to discover the Northwest Passage, left England in 1845, with the Erebus and the Terror; he entered Baffin's Bay, and since his leaving Disco Island there has been no news of his expedition.

His disappearance started numerous search-expeditions, which have effected the discovery of the passage, and given the world definite information about the rugged coasts of the polar lands. The boldest sailors of England, France, and the United States hastened to these terrible latitudes; and, thanks to their exertions, the tortuous, complicated map of these regions has at last been placed in the archives of the Royal Geographical Society of London.

The strange history of these lands crowded on the imagination of the doctor, as he stood leaning on the rail, and gazing on the long track of the brig. The names of those bold sailors thronged into his memory, and it seemed to him that beneath the frozen arches of the ice he could see the pale ghosts of those who never returned.
