The Friedrichsteiner Eishöhle is a large pit cave, well lighted by daylight. It is sheltered from any winds by the great trees which grow all around it and even over the rock roof. A long, steep slope leads straight into the pit and from the top the ice floor is in full sight. On both sides of the slope the rocks are almost sheer. Over the bottom of the slope the rock roof projects at a great height. The sides of the cave rise perpendicularly at least forty meters, and in fact, the cave suggests an unfinished tunnel set on end. Some years ago, the _Deutschen und Oesterreichischen Alpen Verein_ built a wooden staircase, in a series of zigzags, on the slope. This staircase should have been cleared off earlier in the year, but, of course, the matter was neglected. Down these steps we descended until they became covered with snow, and lower down with hard ice. All this was winter's snow which fell directly on to the slope and gradually melted and froze again, so this was really a miniature glacier. It was not subterranean ice at all. We cut down the snow, but had to stop when we came to the ice, as it would have involved a couple of hours at least of the hardest kind of step cutting; and this my guide did not care to undertake, especially as he was nearly killed on this slope the week before. He had reached, with some tourists from Trieste, a place above that where we stopped, when he slipped and fell down the slope, shooting clear across the cave, where he remained until ropes were procured, and he was dragged out. He afterwards showed me the numerous cuts and bruises he had received on his perilous glissade. We had to stop also for another reason. I had unwisely brought as wrap, a thick overcoat reaching to the knees, and this was such an impediment on the icy staircase, that I took it off, and soon began to feel long shivers creeping down my spine. This question of extra clothing for glacière exploration is hard to arrange. One must guard against most trying changes of temperature. For, on entering a big glacière, the heat of a July day without, will, at a distance of only a few meters, give place to the cold of a January day within, and nothing could be better devised than a big glacière to lay the seeds of rheumatism. It is difficult to plan a garb suitable to meet all the varying conditions, but the dress must be cool and warm, and light enough to permit free motion. The clothes I have found most practical are a thin waistcoat and thick trousers, and two short sack coats, one of them a heavy winter one. The coats should button at the throat, and it is well to place straps round the bottom of the trousers. Thick kid gloves should always be worn in caves, to save cutting the hands on rocks or ice in the darkness, and hobnails may prevent some unpleasant slips.
