zach was faring the worse of his fight ; he was caught in a headlock , his jeering opponent stormed blows down on his head and face : but zach twisted his head : instantly his opponent screamed : drove his elbow into zachs face with all his strength : zach crumpled , his face swollen , and his mouth bloody , like the gypsys side , which zach had bitten into , hard : the gypsy collapsed on his side , howling from the pain .
