The tragedy of a German boy, who overdid it:
A Warning from Mark Twain's Tom Sawyer)
He (Tom) entered the church, now, with a swarm of clean and noisy boys and girls, proceeded to his seat and started a quarrel with the first boy that came handy. The teacher, a grave, elderly man, interfered; then turned his back a moment and Tom pulled a boy's hair in the next bench, and was absorbed in his book when the boy turned around; stuck a pin in another boy, presently, in order to hear him say "Ouch!" and got a new reprimand from his teacher. Tom's whole class were of a pattern -- restless, noisy, and troublesome. When they came to recite their lessons, not one of them knew his verses perfectly, but had to be prompted all along. However, they worried through, and each got his reward -- in small blue tickets, each with a passage of Scripture on it; each blue ticket was pay for two verses of the recitation. Ten blue tickets equalled a red one, and could be exchanged for it; ten red tickets equalled a yellow one; for ten yellow tickets the superintendent gave a very plainly bound Bible (worth forty cents in those easy times) to the pupil. How many of my readers would have the industry and application to memorize two thousand verses, even for a Dore Bible? And yet Mary had acquired two Bibles in this way -- it was the patient work of two years -- and a boy of German parentage had won four or five. He once recited three thousand verses without stopping; but the strain upon his mental faculties was too great, and he was little better than an idiot from that day forth -- a grievous misfortune for the school, for on great occasions, before company, the superintendent (as Tom expressed it) had always made this boy come out and "spread himself."
