WIND CAVE NATIONAL PARK. This park, created by act of Congress on 9 Jan. 1903, IS 12 miles northwest of Hot Springs in Fan River County, S. Dak. It is on the southeast slope of the Black Hills and has an area of nearly 15.000 acres. The cave has extensive galleries in Pahasapa limestone with many fine crystal formations on its walls. It was once the channel of subterranean streams and owes its origin to the solution of the limestone by water. The name is appropriate because at most times a strong air current is passing into or out of the narrow entrance to the cave. The park includes a game preserve of 4,1h0 acre, in its northwestern corner, maintained by the United States Biological Survey It contained (1918) 42 head of buffalo, 90 bead of elk and a small herd of ano.lope.

They
expand fully only in sunshine and nod with half-closed corollas on cold, dark days and at night. The plants choose mossy stumps in swamps, or damp thickets for their habitat and have large basal leaves later in summer. On the prairies the red wind-flower (A. hudsoni ma) and the pasque-flower (PitIsatilla patens) bear this name. Another European wind-flower is Geo:nano pneumonanthe, a low, blue-flowered marsh plant.
