rapidly as possible, and promises very satisfactory and interesting results in the near future." "The early geological reports represent the Magnesian Limestone series as made up of seven members. Following Swallow, these may be briefly described in the present connection. Beginning at the top, they are: First Magnesian Limestone. First, or Saccharoidal Sandstone. Second Magnesian Limestone. Second Sandstone. Third Magnesian Limestone. Third Sandstone. Fourth Limestone." "The Fourth" Magnesian Limestone, or lowest number of the Ozark series recognized, has its typical exposures along the Niangua and Osage rivers in Morgan and Camden counties. Professor Swallow, in his Missouri Geological Survey Reports I. and II., 1853 and 1854, says: "Caves, natural bridges and subterranean streams occur in the valley of the Osage and its tributaries." The same authority of forty years ago also mentions that "Some of the grandest scenery in the State is produced by the high castellated and mural bluffs of this (Third Magnesian Limestone) Formation, on the Niangua and the Osage." Another reference to the scenery on these rivers describes it as "Wild and grand, beautiful and unique;" with "gaudy-colored bluffs." In the section on building materials he remarks: "One of the most desirable of the Missouri marbles is in the Third Magnesian Limestone on the Niangua. It is fine-grained, crystalline, silico-magnesian limestone of a light drab, slightly tinged with peach-blossom, and beautifully clouded with the same hue or flesh color. It is twenty feet thick and crops out in the bluffs. This marble is rarely surpassed in the qualities which fit it for ornamental architecture." The Ozarks in the extreme southern portion of the state are even less known to the world, but the scenery is grand, the climate delightful, and the caves worthy of a visit for themselves alone. The State of Missouri being one third larger than England, and of equal size to Switzerland, Holland, Belgium and Denmark combined, it is not surprising that interesting discoveries are still to be expected. The climate is so varied on account of the range in latitude and altitude, and the natural resources are so great, the claim has been made that if the State were surrounded by an impassable wall, its citizens need not be deprived of any article necessary to a refined and luxurious mode of living: and according to Mr. Henry Gannett in "The Building of a Nation," the population in 1890 was 73.42 per cent. native whites of native parents, the colored a little less than 6 per cent., and nearly two-thirds of the balance, native born of parents, one or both of whom were foreign.
