The methods of directing and using aggression in children are demonstrated in studies of the Americans of the continental United States, the Kwoma of New Guinea, and the Alorese of the Dutch East Indies. We move from the creation of frustration in children through the expression of aggressive responses to the various ways the aggressive responses are directed and utilized. Dr. Bullock’s narration is closely linked to dance action and original musical effects. The types of stimuli that frustrate children are explained. As each example is followed to its logical end of aggressive behavior, one can understand the hit-and-run tactics of the Kwoma, the competitive spirit of the American, and the inferior and helpless feeling of the Alorese. The battle scenes presented at the end of the Kwoma and Alorese groups throw our concept of war into a new mental perspective.

Wind, heat, cold, and rain combine to weather the rocks and break them down. But the face of our earth is molded and the decayed rock carried away from one place and deposited in another mainly by water. The deposits laid down by water, wind, or ice produce after long periods of time and under pressure, rocks which are classed as sedimentary.

Each of these sedimentary rocks is formed in a different way; limestone by chemical precipitations, sandstone by grains of sand cemented together, shale from beds of mud or clay pressed and cemented into thin layers, and conglomerate is made of gravel or pebbles of assorted sizes cemented together. You will be introduced to one of the most interesting features of sedimentary rocks -their fossils. These records of living things are guides to the history of life on the earth.
