Margy’s mother was assuming an understanding in matters concerning which there had been no adequate experience on Margy’s part. Protected continually from pain herself, how could she understand the meaning of the word! To her the cat was just another musical instrument. Best of all, it was one upon which she could play. Donald’s method, though not recommended here for general acceptance, was at least effective. ILLUSTRATION I [Sidenote: Donald Takes a Hand] Donald was an obedient child, and closed his book promptly. He also, with some satisfaction in the duty assigned him, sat himself down on the rug near his baby sister, and his attitude of watchful waiting might have struck an observer as purposeful and determined. Margy held pussy firmly by the loose fur at the back of the neck. She stroked her until she was fairly quiet again, then quickly gave the long tail another hard pull. Quick as thought, Donald reached over and pulled his sister’s hair vigorously. She howled lustily, and the cat ran away. Donald let her cry for a little while, then gave her back the recaptured cat and sat again near her. Before long the pulling occurred again, and again Donald pulled as lustily at Margy’s curls. “Do you see what it’s like? Do you like to have your hair pulled? Are you going to quit it?” he inquired. Margy adored Donald, and it did not occur to her to resent his means of enforcing his lesson. “Want the cat back? You can have her if you won’t pull her tail. Will you let her tail alone?” he asked again. Margy said she would, and Donald again captured the cat and put it into her arms. This time Margy did not pull its tail. She stroked it, still holding it tightly by the fur; but she had learned that pulling a cat’s tail had sad consequences when Donald was near. She never repeated the act when her brother was within reach, although she did it when alone or with her mother. Pulling hair is not a good form of punishment, but Donald’s method was based on sound principles, of which of course he was utterly unconscious. A baby should not be asked to make judgments, but he should be taught that pleasant consequences follow some acts and painful ones follow others. This is nature’s method of teaching human beings, and no one can improve on it as a method of last resort for the young human animal. ILLUSTRATION 2 “Look what I’ve found,” Harry Jennings cried to his friend, Captain Stanhope. The captain was sitting on a park bench reading his morning paper, and Harry had been running races with Gyp up and down the gravel walk. He came up to the bench, now, with a handful of souvenir post cards in his hands. [Sidenote: Applying “Golden Rule”] “Some one has been addressing them here in the park, and then went off and left them on the bench,” he continued. “See, they’re addressed to people all over the country, and not a stamp on one of them!”
