Face the children away from you and tell them you are going to practice them in obeying the order, “Don’t look.” Tell them that when you have given the order, they are not to look around, under any circumstances, no matter even if a contradictory order is given, until you call “Time.” Then give the order and behind their backs try different devices to entice them into looking. Tell a story and pretend to illustrate it, saying, for instance, “Jack and Jill went up a hill, like this” (stamp about or make noisy gestures), “to fetch a pail of water, like this” (make chalk marks on the blackboard, as if drawing) “and broke his crown, like this” (drop a book or something heavy), and so on. Suddenly speak into the ear of one, saying, “Look here,” tap another on the shoulder excitedly, and so on. (5) _Double orders._ Make a list as in drill 3, but with two orders for each child, thus: “John, hand me that book, and put this on the table.” Use in the same way as in drill 2. (6) _Prohibitions._ Tell the children you are going to practice them still further in obeying “Don’ts.” Then, give the order: “Don’t make any sound until I call ‘Time.’” Allow them to move their heads, arms, feet; even to move about, though this privilege should be forfeited by any one failing in the slightest degree to observe the command. Watch and listen for the faintest sound and have them do the same, but only the teacher must call attention to any voluntary or involuntary breaking of silence. At the end of five minutes call “Time.” Discuss with the children what they could do to observe the command better or more easily and repeat the exercise. Then tell them to get into a comfortable position, one that they can maintain indefinitely, as they are to remain not only silent but motionless. Ask them to pretend that they are to have their pictures taken, that the slightest motion, shifting of position or twitching—breathing and blinking of the eyes excepted—will spoil the picture, and say, “Now, don’t move till I call ‘Time.’” Call “Time” at the end of two minutes, as this is a very severe ordeal. Further practice, however, should make them able to hold this position for five minutes longer. Tell the children you are going to command, “Don’t talk,” and then are going to try to surprise them into talking or asking a question, but they must say nothing under any circumstances. Tell them they are supposed to be mutes, without the power of speech—as dumb as the animals. Then give the command, “Don’t talk,” but continue to talk yourself, telling either a story or something about which children would ordinarily ask questions, and if this does not succeed, abruptly ask one of the children a question, trying to take him off his guard or to startle him into a reply.
