There is a telescope on the Uetliberg, close to Zürich, through which on a clear day it is possible to detect the stone signal on one of the peaks of the Diablerets, near Lausanne, almost at the other end of Switzerland, being a distance of not less than ninety-six miles. This signal is only about four feet high. Climbers on the Titlis, forty miles distant, can easily be seen through this telescope, as well as the hotel on the Faulhorn, sixty miles distant, and, in very fine weather, the small trigonometrical signal itself. From the instrument on the Rigi the crevasses in all parts of the Alpine chain, and also one of the church clocks in Schaffhausen, may be plainly seen. From the observation station on the Riffelalp the movements of the Matterhorn climbers can be followed as clearly as if they were within hailing distance. Through the telescope on the Schynige Platte in the Bernese Oberland the timid and unapproachable chamois may be observed on precipices miles distant, and persons on the four-miles-distant Faulhorn are easily distinguishable. [Illustration: "THEY WERE ALMOST BURIED IN SNOW AND DOING THEIR UTMOST TO STRUGGLE THROUGH IT."] When it is remembered that there were seventy five fatalities in the Alps last year, and three hundred and fifty more or less grave accidents to climbers, it will be seen that observation of the movements of persons upon the mountains through the telescopes fulfils a useful purpose. There is no doubt that Mr. Turner, a well-known English Alpinist, owes his life to-day to the fact that he was watched in this way during his attempt to cross the Col Bonder-Krinden (seven thousand two hundred feet high) last season. He was accompanied by a guide named Amschwand. An observer at a telescope watched their ascent and followed them step by step, until a blinding snowstorm arose. They were then lost to view for several minutes, when suddenly they were detected apparently almost buried in snow and doing their utmost to struggle through it. The observer gave the alarm and, it being then late in the afternoon, it was decided to send a search-party out on the following morning at sunrise. Meanwhile the couple on the mountain realized that their only hope of life was to reach a hut on the pass, and they heroically struggled on through six feet of snow. They arrived at the hut exhausted and without food, for they had brought none, as the Col, under ordinary conditions, is easy to climb. The snow penetrated into the hut and the unfortunate pair were literally buried beneath it. Next morning ten guides left Adelboden to search for them, solely because their distress had been noticed through the telescope. The rescuers, however, were driven back by avalanches, several of them being injured. A second search-party was finally got together, and they succeeded, after great hardships and at no little risk, in digging their way to the hut, where they found Mr. Turner and his guide
