FLUOR-SPAR. See Fluorite. FLURSCHEIM, flur'shim. Michael (1844 — ). A German agitator of land-reform, born in Frankfort-on-tho Main. He lived in the United States from 1867 to 1872. Upon his return to Germany he founded the iron-works at Gaggenau, Baden, and in 1892 made bis home at Castagnola, near Lugano, Switzerland. He aims to show that the revenues accruing tothe individual owner from taxes and ground rent are the primary cause of the accumulation of vast fortunes by the few, and of the indigence and suffering of the masses; and that the control of land by the Slate would remove this evil and would at the same time counteract the evils of socialism. The following maintain the advantages of individualism and are a few of his principal works : Auf friedlicl Wcrre (1884; frequently reprinted) ; Deutschland in hundert Jdhren (2d ed. 1890); Her ei Rettungsweg (rev. ed. 1S90) ; and Rent, Interest, and Wages (1891). In the last-mentioned work the author acknowledges his great indebtedness to Henry George, whose ideas, however, he sub- jects to some modification. FLUSHING ("Dutch Vlissingen) .
