The first exposition of conservation and its builders; an official history of the National conservation exposition, held at Knoxville, Tenn., in 1913 and of its forerunners, the Appalachian expositions of 1910-11, embracing a review of the conservation movement in the United States from its inception to the present time . engaged in mining the Florida phosphates. It is alwavs more agreeable to bring lo an assembly of this kind the solutionof some difticult prol)lem. In this instance, however, I must content myself withthe statement of a problem for which the solution is yet to be found. Two kinds of phosi)hale rock are now being mined in bdorida, the land peb-ble and the hard rock. The deposits which carry the hard rock phosphate arefound o\er a considerable extent of country in the western part of the centralpeninsular Ilorida. The area includes the southern part of Columbia and Suwan-nee Counties, the western part of Alachua and Marion Counties, the eastern partof Levy, Citrus and Hernando Counties, and the northern part of Pasco north to south the hard rock area extends through a distance of about 100miles. Its* width from east to west is variable. The greatest width is found inMarion County, almost the whole of the western half of this county being included *State Geologist of z o H o Ll) Oeratin,iL;are found in a narrow helt reaching from Alachua to llernandoCounties.

The land ])el)hle phosphates are found in southern idorida in Polk and llills-horo Counties, and, as will he explained later, are of a different type from the hardrock deposits.
