TIE CURvING OF A BASEBALL

an Imperfect Globe and In compart.
 con Wth leo Size Much Tougher
 Than sao Surface of tho Earth
 The real reason why a baseball con be throwu so chat 1t win describe won. deru curves during It's progress through che oIr Is that every such bol. Hns a surface made up Of mountains, valleys. crotsrs, canyons, gorges plains uuI other Irregularities of the surface thut when che difference in size is taken Into consideration, makes tho surface of rhc earth seem like plate g0ss

 And sa wnGc It Is partly in che art or EraeE Can professional pitcher has In no.Uue and reIgasIng thc baseball na un throws Ig iJ Is also due Co the HcJ rmtu baseball has a wonderfully rough surface Umlust which che uIr catches and turns Ot thut gives it Che curve

 Even Che billiard bah has a surface much rougunr .u comparison to its size nau che surface of the earth, and we refer Go a billiard ban as about tbc smootncst thing known "As smooth as a billiard baI Is a well known sImWo For Che same reason thot perfectly smooth baseball could not be curved. a perfectly smooth and per fce.Iy round billiard ball could not be made to curve on Che table It would not mke aEne.Ish" as billiard players call 1t when tncy make a baIi go for. ward and Chen roll backward OF In uay direction just by the manner Iu which tnnv strike It with a cbulEcd cue
 This fact of roughness causing it to suIn becomes 1u too evident when player forgors to chalk his enc and pnvs several shots thereafter If che leather tIp ,r thc cue becomes shiny t win slip on che ball There Is no purchase with which It can take hold. But chalk Is sticky stun and Jhc gran uIcs are large. SO tbut a well chaIkcd cue has a very rough surface, and this rough surface Of the dip Of the cue dts into .ne rough projections on the ball. and thereby a uUlI can be given Iot rr twist In order to accomplish th.s successfully moreover the billiard cloth nap must be new and therefore rough
