JENOLAN CAVES, a series of remarkable caverns in Roxburgh county, New South Wales, Australia; 113 m. W. by N. of Sydney, and 36 m. from Tarana, which is served by railway. They are the most celebrated of several similar groups in the limestone of the country; they have not yielded fossils of great interest, but the stalactitic formations, sometimes pure white, are of extraordinary beauty. The caves have been rendered easily accessible to visitors and lighted by electricity. JENSEN, WILHELM (1837- ), German author, was born at Heiligenhafen in Holstein on the 15th of February 1837, the son of a local Danish magistrate, who came of old patrician Frisian stock. After attending the classical schools at Kiel and Lübeck, Jensen studied medicine at the universities of Kiel, Würzburg and Breslau. He, however, abandoned the medical profession for that of letters, and after engaging for some years in individual private study proceeded to Munich, where he associated with men of letters. After a residence in Stuttgart (1865-1869), where for a short time he conducted the _Schwäbische Volks-Zeitung_, he became editor in Flensburg of the _Norddeutsche Zeitung_. In 1872 he again returned to Kiel, lived from 1876 to 1888 in Freiburg im Breisgau, and since 1888 has been resident in Munich. Jensen is perhaps the most fertile of modern German writers of fiction, more than one hundred works having proceeded from his pen; but only comparatively few of them have caught the public taste; such are the novels, _Karin von Schweden_ (Berlin, 1878); _Die braune Erica_ (Berlin, 1868); and the tale, _Die Pfeifer von Dusenbach, Eine Geschichte aus dem Elsass_ (1884). Among others may be mentioned: _Barthenia_ (Berlin, 1877); _Götz und Gisela_ (Berlin, 1886); _Heimkunft_ (Dresden, 1894); _Aus See und Sand_ (Dresden, 1897); _Luv und Lee_ (Berlin, 1897); and the narratives, _Aus den Tagen der Hansa_ (Leipzig, 1885); _Aus stiller Zeit_ (Berlin, 1881-1885); and _Heimath_ (1901). Jensen also published some tragedies, among which _Dido_ (Berlin, 1870) and _Der Kampf für's Reich_ (Freiburg im Br., 1884) may be mentioned. JENYNS, SOAME (1704-1787), English author, was born in London on the 1st of January 1704, and was educated at St John's College, Cambridge. In 1742 he was chosen M.P. for Cambridgeshire, in which his property lay, and he afterwards sat for the borough of Dunwich and the town of Cambridge. From 1755 to 1780 he was one of the commissioners of the board of trade. He died on the 18th of December 1787.
