At the entrance the breeze was strong enough to blow out a candle. This breeze was not noticed at other times. From December to February inclusive, on the contrary, the breeze was reversed. From July to October, 1897, the walls of the cave were moist. From October to February they were dry. In February frost began to appear on the walls. On March 12th, 1898, the walls were covered with frost. The ice appeared at a spot nearly at the end of the cave on the 26th of March, 1898. At a place about 6.50 meters nearer the entrance, however, is where most ice forms. This place Mr. Kovarik calls _Locus Glacialis_. The ice appeared here about the 29th of May, 1898. It increased rapidly up to June 12th, when it was at its maximum, and was about two meters in width. It generally covers the north wall from top to base. The greatest thickness in 1898 was 29 centimeters.
