每个孩子都应该玩泥饼、捉蚱蜢、玩水虫、养蝌蚪、抓青蛙、玩泥龟、采接骨木果、摘野草莓、捡橡子、采栗子、爬树、涉溪、赏睡莲、观察土拨鼠、蝙蝠、蜜蜂、蝴蝶，养各种小动物，在干草场玩耍，捡松果，滚石头，玩沙子，抓蛇，采越橘和胡蜂窝；任何被剥夺了这些乐趣的孩子，都被剥夺了教育中最美好的部分。
Every child should have mud pies, grasshoppers, water bugs, tadpoles, frogs, mud turtles, elderberries, wild strawberries, acorns, chestnuts, trees to climb, brooks to wade in, water lilies, woodchucks, bats, bees, butterflies, various animals to pet, hayfields, pine-cones, rocks to roll, sand, snakes, huckleberries and hornets; and any child who has been deprived of these has been deprived of the best part of education.
