It is a matter of curiosity to see how immediate has been the effect of the measures adopted by the Tennis Association to abolish the "shacker" nuisance. It is true that there has been no attempt to make and enforce any rule. The simple request that a certain regulated scale of fees be adopted, and that no boys be employed except when found at certain specified stations, seems to have had the desired result. Not only have the numbers of idle small boys who used to infest every part of the college grounds greatly diminished, but those that have remained seem to have acquired a strangely altered tone of civility. But precisely why the ardor of the "shacker" in the pursuit of the wayward tennis ball should have suffered so sudden a cooling, and his numbers so sadly diminished, is not easy to see. We are perhaps forced to the conclusion that a reckless extravagance had characterized the players of tennis previous to the new rule, and that prices paid to "shackers" had ruled much higher then at present. Still we can hardly believe that the average paid "shackers" under the new arrangement is less than before. That shacking is losing its attractions may be due to the fact that the element of chance is now divorced from the employment. We can hardly doubt that the fascination attaching to the chance of one day receiving a quarter in payment for his labor, although receiving the next day nothing but thanks, must be great to the youth of the street, educated in the school of dime-novel literature. Hereafter we cannot look to be favored with the presence of these youths, save when they are found among the great unnumbered outside the fence at a match game of ball.
