Another derelict was the _Advance_. This vessel, provided by the munificence of an American merchant, Mr Grinnell, was placed under the command of Dr Kane, and sent northward in 1853 to search for Franklin. Kane made an historically famous progress up Smith Sound to such a latitude as to bring that route into favour among Arctic explorers. The return journey was, however, a terrible one. After two winterings in the ice he abandoned his poor ship in April 1855, and made a three months' sledge-journey to the Danish settlements in Greenland. Has the _Advance_ ever been seen by later explorers; has it been iced up for twenty-two years; or have shocks and nippings shattered it to fragments? The _Polaris_, connected with an American expedition, was abandoned in October 1872, and the officers and crew returned to the United States by boats. Storms, driftings, and other calamities led to a division of the crew into two parties. One worked their way down Davis's Strait, or were drifted thither, and were picked up in April 1873 by the _Tigress_, off the coast of Labrador; the others, making boats out of some of the timbers of the _Polaris_, managed to reach the eastern side of Baffin's Bay, where they were picked up by the _Ravenscraig_ whaler in the autumn of the same year. The poor _Polaris_ scarcely deserved the name of a derelict; for only portions of a hull were left stranded on a coast of the icy sea. One more example, and this also from the Arctic regions. In 1872 the Austrians did excellent work in furtherance of maritime research by fitting out a private expedition in the small ship _Tegetthoff_, under the management of Lieutenants Weyprecht and Payer. Instead of taking the Baffin's Bay and Smith Sound route, the _Tegetthoff_ coasted round Norway to Nova Zembla, and wintered off that island. Instead of being free to sail in the following summer, the ship was fast locked in an ice-floe from which she could not be extricated, and drifted when the floe drifted. Luckily the drift was just in the direction which the explorers wished to go, almost due north. They came most unexpectedly to a group of islands until then totally unknown, the largest of which they named Franz Josef Land, in honour of the Emperor of Austria. They wintered in the high latitude of eighty-one degrees north, and made excellent sledge-expeditions in the spring of 1874, an account of which, together with other interesting details, was given last month in this _Journal_. Returning to the _Tegetthoff_, they found her still immovably fixed in the ice. A prospect of exhausted stores and provisions led to a resolution to abandon the ship; this was done in the summer; and a boat-voyage of three months brought the hardy adventurers to the mainland in the autumn of the same year. We cannot help fancying that the abandoned ship will one day fall into friendly hands; and if it does, the salvors will find many interesting things on
