They were by no means the worst boys who did such things, but only the most thoughtless. Still, there was a public opinion in the Boy's Town which ruled out certain tricks, and gave the boys who played them the name of being "mean." One of these was boring a hole in the edge of your school-desk to meet a shaft sunk from the top, which you filled with slate-pencil dust. Then, if you were that kind of boy, you got some little chap to put his eye close to the shaft, with the hope of seeing Niagara Falls, and set your lips to the hole in the edge, and blew his eye full of pencil-dust. This was mean; and it was also mean to get some unsuspecting child to close the end of an elderwood tube with his thumb, and look hard at you, while you showed him Germany. You did this by pulling a string below the tube, and running a needle into his thumb. My boy discovered Germany in this way long before he had any geographical or political conception of it.
