The temperature which Mr. Kovarik recorded on the 16th of April at _Locus Glacialis_ of +1.1 seems an anomalous one. On writing to him he sent me the following explanation: "April 16th, after I left the thermometer at _Locus Glacialis_ the usual time, I noticed that it registered +1.1° C. It seemed singular, for at both the Division and the End, the thermometer registered considerably lower. I left the thermometer at its place for about an hour longer, and noticed then that it did not register differently. I would suggest this explanation: This is true about water that upon freezing it gives off its latent heat. Now on April 16th some water dripped into the cave on the wall near where the thermometer was, about 1.50 meters from the floor. The amount of water was very small, but as it came in contact with the cold wall it began to give out its latent heat which affected the close by thermometer. The temperature of the rock was without doubt between -1.° and -3°." Freezing Cavern at Brainard, Iowa. (Alois F. Kovarik, _Decorah Public Opinion_, September 20th, 1899.)--This little cave is situated on the north side of a hill about 1.5 kilometers northwest of Brainard. It is about 4.50 meters deep. On June 10th, 1899, Mr. Kovarik found the floor and walls covered with ice. The temperature was 0° C. The owner claims to have taken enough ice out of it on July 4th, 1897, to freeze cream. Freezing Cave near Elkinsville, Brown County, Indiana. (Clipping from a western newspaper, 1896.)--The entrance is said to be overlapped by trees and to resemble a mine shaft. The winding way leads to a hollow some 15 meters below the surface, resembling a broad vaulted corridor, which is known to the natives as the devil's chamber and where the temperature is low. From this point several galleries lead further in, and from one of them comes a blast of icy cold air. This passage is similar to the one at the entrance to the cave, but after a few meters frost is visible, and further on it is thick on all sides, like the crust that is formed on the pipes of an ice plant. The narrow way leads to a big chamber, known as the ice vault. In this dome, which is fully 30 meters in width, the ice forms a large stalagmite and is of unknown depth. Freezing Gully on Mount Abraham, Maine. (Jackson, _Report of the Geology of Maine_, 1839, III.)--Ice was found in June at an altitude of 1032 meters among the boulders in one of the gullies of Mount Abraham.

Ice in a Hole at Dixville Notch, New Hampshire.--Mr. John Ritchie, Jr., of Boston, has examined this place, which he is sure is a refrigerator. It is in a hole north of the cliff and near its top.
