FORTY-YEAR CLOCK.

Jeweler Makes n Timepiece Thai B< Will Probably Wever Have to 'Wind Again. A jeweler, calculating that he would in all probability live about 40 years, and during that time spend about 60 days winding the house clock—allowing two minutes each day for the taskdecided that he would make a clock which would need winding but once during that period. Hf spent hie odd minutes at the task, and has succeeded in producing a clock which is the only one of its kind in the-world, says the New York Herald. This timepiece is 15 inches in diameter and weighs 75 pounds. The movement is so geared that the barrel wheel, containing the mainspring, revolves only once in 2 Vfc years. When this wheel has made 56 revolutions somebody will have to give the key 17 turns. The clock will then be wound up for another 40 years. The first wheel from the barrel wheel crawls around at the rate of one turn a year. The dial plate is six inches in diame-ter. The movement is full jeweled. The cork is put in -a hermetically sealed glass case, and it will work in a vacuum, thus lessening fraction and preventing the oil from drying.
