WILDBAD. — CHAFT. IV.

through the Kegel- or Millbrook-vale, which extends from Kaltenbrunn to the valley of the Enz. These accumulations continue tili to the embouchure into the Enz-valley, the sole of wliich is covered witli them to such an extent as to cause a deviation in the course of the river. Another ag- gregate of stone-fragments, by wliich the bottom of the valley is covered tili down to the Lautenhof, occurs at the niouth of the Rollwasser-Tobel.

The rock prevalent near Wildbad, is a gross-grained granitc, composed of smokc-coloured quartz, yellowish fieldspar, and silver white mica; in this shape it appears particularly at the silver-wcar ( Silberinehr ). Beyond Wild­bad a compact, small-grained sandstonc, of an ashy bue, enters almost inipcrceptibly into the composition of the rock, and at the saine time the particles of fieldspar and quartz increasing in size, often appear in a cristallinc shape. In the upper portion of the Enz valley flesh coulored Albite, in picces of scveral cubic inches, bccomes the prin- cipal constituent of the granite, in lieu of the common fieldspar. There also the rhombs of mica are of more tlian a square inch in circumference.

The granite rocks near the Sprollenmiihle contain a mineral found nowhere eise in these parts, called Leptinite ( Weissslein) ; it consists of a homogcneo'us mass of blueish grey fieldspar, with quartz, mica and ccerulean cyanite.— The stone piedestal of the Schiller statue at Stuttgart con­sists of granite quarried near the Kdlbermükle , in the neigh- bourhood of Wildbad. Some years ago, blue colored granite was discovered in the site of the A eue Badgebäude at Wild­bad , when the rocks around it were blasted in Order to obtain the extent of level ground, necessary for the con- struction of this building.
