Watch Mechanism.

J Few piticcs of machinery show | more marvellous features than that «I the watch. As a general proposition it may be stated that a watch is tho smallest, moist delicate instru- , ment of the same number of parts , tl'"t lias ever been devised. About : 175 different pioces of material euj ter into its construction, and upi ward of 2,100 separate operations I are eompri.ved in its manufacture.

Certain of the facts connected with ite performances are incredible when considered as « whole. A blacksmith strikes several hundred blows on his anvil in a day, and. as a matter ol connse, i.s glad when Sunday comes ; but tho roller jewel of a watch makes every day—and day after day—l32,ooo impacts against tho folk, or 1 o/,080.000 blows during the course of a year, without stop or rest--or some 3,153,600.000 blotts duimg the space of 20 years, the period for which a watch its usually gu.-ranteod to keep goo;! time.

l?nt the wonder of it dues not cease here. It has been calculated that the power that moves the watch is equivalent to only four times the force used in a flea's jump. The watch-power i.s therefore what might be termed the equivalent of four {lea-power. One horse-power would suffice to operate 270,000,000 watches. Furthermore, the balance-wheel of a watch iV moved by thifi four fieapnwer 1.13 inches with each vibration. or 3.>)sß;'{ miles contiunously in one year. Not miioh oil is required to lubricate the little machine on its 3,500riU! - It takes only one-tenth

of a drop to oil the entire machinery for a year's .service. i)U*i.'LL uu.tjrL,Au> J£j ji; C'filir •'''- 1 - biiccv-. ; «i:ii racsUcine io ilhe iri iw.a'i I An, I-,;.', i 5; t-v i.l clUldiCu i.i i;-ii.'fj Liii.c, e-lioriera ana 'U-nu-,1; . it cau to Cliro iJjjii raot.i£« ;uiil i>yi;v iii.t.iy .
