sight of blood, and when he saw it mixed with matted hair along the side of his cudgel, and realized that it was human hair and human blood, and that he, Waldo Emerson Smith-Jones, had struck the blows that had plastered it there so thickly in all its hideousness, a wave of nausea swept over him, so that he almost toppled from his dizzy perch. For a few minutes there was a lull in hostilities while the cave men congregated below, shaking their fists at Waldo and crying out threats and challenges. The young man stood looking down upon them, scarcely able to realize that alone he had met savage men in physical encounter and defeated them. He was shocked and horrified; not, odd to say, because of the thing he had done, but rather because of a strange and unaccountable glow of pride in his brutal supremacy over brutes.
