Mount St. Elias is about 18,000 feet high, and was supposed to be the highest peak on the continent till Mount Logan was discovered a few miles farther inland, that was found to be 1,500 feet higher. The slopes of Mount St. Elias are covered with glaciers, and so far about 4,000 feet of the mountain have defied the efforts of all mountaineers. Two parties will make the attempt this summer, one composed of American scientists, and the other of Prince Luigi of Savoy, who is a nephew of King Humbert of Italy, and some companions. The first attempt to explore the mountain was made eleven years ago, but only an altitude of 7,200 feet was reached. Two years later an Englishman made another effort, and had climbed 11,000 feet of the mountain before he was obliged to descend. In 1891 a party succeeded in reaching a height of 14,500 feet. Halting on this spot to rest before they ventured farther, the weather changed, clouds gathered over them, avalanches began to sweep down the mountain-sides, and the adventurers had to hurry to the base of the mountain. Young Prince Luigi, who will make this present attempt, is most anxious to reach the top of Mount St. Elias. He will have many hardships to endure before he can hope to reach his goal. His party will have to cross the glaciers and ice-clad mountains which lie in his path, and will have to camp many days on the ice, a cold and comfortless proceeding. The Prince declares he has only come for the sport, but his trip may be of great value to the world, for he has in his party a gentleman who is famous for his wonderful mountain photographs. Signor Sella, as he is called, is taking a complete photographic outfit with him, and if the conditions are favorable, will bring us back some mountain pictures that will add greatly to our knowledge of the beautiful Mount St. Elias. GENIE H. ROSENFELD. INVENTION AND DISCOVERY. DIAL CALENDAR.--This is a calendar which combines many good points. It is not only a monthly calendar, but weekly and daily as well. By means of two movable discs the calendar for the week appears in an opening cut in the frame just above the monthly calendar, and lest even then a person should be mystified about the date a broad black band can be shifted daily to mark the actual day. The calendar would appear to be an ideal one if only its owners remember to set it, but the trouble with the shifting calendars is that so few people remember to adjust them. [Illustration]
