the table or plate; this is repeated over and over until the association is formed and then the striking becomes continuous for long periods at a time. Numbers of instances were given of this continued repetition of one act. The returns indicate that this begins not later than the sixth month. This striking by infants of table, chair, plates and the floor with toys, spoons, knives, forks, blocks was mentioned in practically all the returns. Soon the stick comes into use. Those who suffer most from this are toys, the cat, the dog, other children and adults. This tendency increases, especially with boys, from 5 to 10. Whips are made from straps and sticks or are cut from bushes and carried by the boys who constantly strike at everything that comes within reach as the following quotations will show: M., 7, carried club, stick, or cane for gun. Loved to play school and be teacher so he could whip. M., 7, struck trees and fences as "J a k: the Giant Killer." Played policeman and carried club. Boys of 8 lined up with sticks and then charged upon weeds and bushes. M., 9, liked to play horse with whip and use it. Liked to hit weeds, stalks and stems. Boys of 9 struck cat, dog, trees and house with stick. M., 8, hit himself with whip as horse. M., 10, likes to cut tops of grass off with stick. Similar statements were repeated over and over in the returns. Many of the boys and girls say they carry a stick because they feel safer when walking along the street or road. In walking along with a stick it may be used to strike at weeds, animals or even people. It is also dragged along a picket fence so as to make a rhythmic noise. In riding in a vehicle one great pleasure is to use the whip on the horses. Boys and even girls engage in whipping contests, in which two of them with whip in hand beat each other until one or the other gives up. Driving stock also gives great pleasure because the whip can be freely used. Much damage is sometimes done in striking flowers, small trees and other plants of value. There seems to be an almost blind impulse to perform this motion with something in the hand in the shape of a stick or whip.
From the use of the stick and whip the child in the course of time learns the use of the lever. This usually does not occur until the tenth or twelfth year. There is considerable variation here. It is interesting that many children do discover this incidentally in their play with the stick.
Throwing probably develops in the child from striking. In his effort to strike, the object in his hand may slip from his grasp and fall to the floor. In the course of several repetitions of this the child learns to drop things on the floor and from this develops the idea of throwing. The motion is at first awkward and is little more than an aimless motion of the
