I arrived at Farrandsville, Clinton County, Pennsylvania, early on Tuesday morning, October the 11th, 1898, and found a boy, who worked in a brick mill, as guide to the caves.[11] After emptying a small, flat bottomed boat of the water of which it was half full, we rowed across the Susquehanna River; then we walked up the road, along the river bank, for a couple of hundred meters, and struck up the so-called path to the caves. Although the whole of the mountain side was at the disposal of the road maker, no better plan seems to have suggested itself than to make the track go straight up. This saved making zigzags, yet the result is that the path is steep, and as it is rocky and slippery, it is hard travelling without bootnails or alpenstock. [11] I learned of this cave from Mr. Eugene F. McCabe, of Renovo, Pennsylvania. Mr. McCabe took out large pieces of ice from it in the month of August. On December 23d, 1896, he found no ice inside the cave, but a hoar frost covered the rocks; the temperature outside was -5.6°; inside -4.5°: the day was clear and there was no breeze; several matches lighted in the cave were almost instantly blown out by a current of air coming from crevices in the rocks. Mr. Ira C. Chatham, postmaster at Farrandsville, wrote to me on the 19th of October, 1898, as follows: "Your paper on Ice Caves [Journal of the Franklin Institute, March, 1897] at pp. 177 and 178 describes the Farrandsville Cave as near as is possible, as the ice forms in the spring from the snow melting and dropping through the rocks into the cave, and the rocks face directly north as stated." As we went up, I noticed, in one or two places, cold draughts issuing from crevices in the rocks. We soon came to a hollow under a rock, where there were a number of cracks and crevices: the boy spoke of it as the lower cave. It is some sixty meters above the Susquehanna River and cold draughts flowed from the cracks, although we saw no ice. The cave was about twenty meters higher up. One could crawl into it for a couple of meters, and all round it the rocks are somewhat creviced; in fact, I think there are a good many cracks in the entire hill. There was no ice in sight in this hole, but a strong, cold draught poured from it. After an exposure of fifteen minutes the thermometer registered 6° C.; while outside, in the shade, it stood at 15° C. This decidedly sub-normal temperature proved unmistakably, in my opinion, the presence of ice a little further than we could see in. Both holes face about north and are sheltered, by their position and by the sparse forest which covers the ridge, against all winds except those from the north. I talked to the postmaster and the railroad agent at Farrandsville on my return, and they stated that there was no ice in the hole in winter, but that it formed about April and remained over until towards September, showing that the cave is a normal glacière on a small scale.
