Freezing Cave or Gorge, White Mountains, Arizona.--Mr. Frank Hamilton Cushing has told me of this place. It is a cleft among lava rock, which being roofed at the further end, might be described as a cave. In this the ice remains until June or July, much later than anywhere else in the neighborhood. The Zuni Indians worship before this, calling the ice the breath of the Gods, the snow they consider as a sort of down. The region is arid, which makes any water precious, and this fact has developed the element of mysticism about snow and ice among the Indians. Freezing Cave near Galena, Black Hills, South Dakota. (Miss L. A. Owen, _Cave Regions of the Ozarks and Black Hills_. Cincinnati, 1898, page 209): "At Galena, a new mining town of golden promise, there is reported to be an Ice Cave, where ice forms at all seasons, and during the warm weather is a source of comfort and pleasure to the miners." Windholes in the Ozark Mountains, Missouri.--Mr. H. F. Brinckerhoff, of Aurora, Mo., informs me that there are a number of cold air current caves in the Ozark Mountain region. One of them is some 19 kilometers south of Aurora, Lawrence County, and is used for cold storage in summer. There is a cave in a limestone bluff about 15 meters above a river, and in the rear is this windhole, which is an opening about 30 centimeters high and 3 meters wide. A strong current of air comes out from it in summer, and the hotter the air outside, the stronger is the outward coming current. In winter the current is reversed. The outward current is so strong in very hot weather that a handkerchief held in it is straightened out to an angle of about 45°. Freezing Cave and Well at Decorah, Iowa. Described in Part I. (Dr. C. A. White, _Report of Geological Survey of State of Iowa_, 1870, vol. I., page 80. A. F. Kovarik, _Scientific American Supplement_, No. 1195, November 26th, 1898, pages 19,158, 19,159). On June 1st, 1869, Dr. White found the ice dry and well frozen, and he thought it was then accumulating. The cave was cool and apparently dry, and no strong air current was passing through. Mr. Alois F. Kovarik, of the Decorah Institute, has made a valuable series of observations about the Decorah Cave. The temperatures he observed were the following: IN THE VALLEY, LOCUS SHADE.
