A Forty-Year Clock.

Three years ago a Chicago jewelet calculated, that he would im all probability live forty years. Then he decided to make a clock that would have to be wound but once in forty years. He spent his odd minutes at the task, and has succeeded In producing a wonderful piece of mechanism- tine only one of its kind, he claims, in the world. This-forty-year timepiece is fifteen inches in diameter, and weighs seventyfive pounds. The movement is geared so that the barrel-wheel containing the mainspring revolves once in two aud a half years. When this wheel has made fifty-six revolutions somebody will have to give tie key seventeen turns. The clock will then he wound up for another forty years. The first wheel from the barrel moves round at the rate of on» turn a year. The dial plate is six inches in diameter. The making of the work took most of the jeweler’s leisure tor twenty-four months. The movement Is fully jeweled. The clock has been put in a hermetically sealed glass case, and it works in a vacuum, thus lessening friction and preventing the oil from drying.
