By this time we were all chilled to the bone, so, abandoning the idea of entering the Petite Cave, we retreated down the sopping wet, slippery grass slopes to Pralong, and then immediately walked all the way to Cluses to avoid taking cold. The Grand Cave was the most fatiguing trip I ever made after glacières, but the circumstances were rather unusual. THE FREEZING WELL OF OWEGO. On Thursday, June 23d, 1898, I went to Owego, in Tioga County, New York. Inquiries at the Lehigh Valley railroad station and at the chief hotel failed to elicit any information about a freezing well; and in fact, I soon found that the existence of such a thing was a blank to the rising generation. So I called on an old resident of Owego, who told me that he knew of the well in question and that it was filled up with stones many years ago; but that he remembered that, when he was a boy, it used to freeze, and that it was spoken of as the deep well or freezing well. I then walked up to the site of the well, which is about one and a half kilometers to the northwest from the centre of Owego and about one kilometer from the Susquehanna River. It is directly in the middle of the highway, and nothing is now visible but a heap of stones. Near by was the house of a Mr. Preston, who told me he was born in 1816, and had lived all his life at this spot. He said that the well was about twenty-eight meters deep, and that it went first through a layer of sand and then through a layer of gravel. He had more than once been down the well and had seen the sides covered with ice. A bucket sent down for water would sometimes come up with ice on the sides. Whether the water at the bottom ever froze, no one knew, for the ice caked and filled up the bore at about two-thirds of the way down and became so thick, that as Mr. Preston put it, "it was just like hammering on an anvil to try to break it." He also stated that another well was dug about one hundred meters further down the road, and that originally this sometimes had a little ice on the sides. Of late years however, it was covered over with a wooden top and since then no ice was known to form. I could obtain no information about any other wells in the neighborhood ever showing similar peculiarities. THE ICY GLEN, NEAR STOCKBRIDGE. The Icy Glen is situated on Bear Mountain, about one kilometer from Stockbridge, Massachusetts. It is in the midst of fine woods and there are many big trees in it. The bottom of the glen is full of rocks and boulders, among which there is a rough path. I was told that ice remained over there much longer than anywhere else in the neighborhood, sometimes as late as May. On the 3d of July, 1898, I not only found no traces of ice or snow, but the temperatures under the boulders showed nothing abnormal. To make up for this, however, there were legions of mosquitoes.
