The Wonders Of A Watch

A Boston jeweler, who ñas a uuem for advertising, as well as a genius lor mechanics, has been reminding his patrons, lately, that a watch is the smallest, roost delicate machine that was ever constructed of the sanie uumv ber of parts. About one hundred and seventy-flve different pieces of mater rjal enter into its construction, and upwards of twenty-four hundred separate operations are comprised in its manufacture. Some of the facts connected with its performance are siniply incredible, when considered in total. A blacksmith strikes several thousand blows on his anvil in a day, and is right glad when Sunday comes around; but the roller jewel of a watch makes every day, and day after day, 432,000 impacts against the fork, or 157,680,000 blows in a year without stop or rest, or 8,158,000,000 in the short space of twenty years. These figures are beyond the grasp of our feeble intellect; but the marvel does not stop here. It has been estlmated that the power that moves the watch is equivalent to only four times the f orce used in a flea's jump; consequently it might be called a four flea-_ power. One borse-power would sufflce to run 270,000,000 watehes. Now the balance-wheel of a watch is moved by this four ttearpower on and fortythree one-hundredths inches with each vibration- three thousand, flve hundred and fifty-eight and three-quarters miles continuously, in one year. If you would preserve the time-keeping qualities of your watch, you should take it to a competent watchmaker
