The man took the third stave, a bar of elm four feet long and as thick as a man's wrist, and came round to the mule again on the side away from Clare and Johnstone. He lifted the weapon high in air, and almost before they realised what horror he was perpetrating he had struck three or four tremendous blows upon the creature's back, making as many bleeding wounds. The mule kicked and shivered violently, and its eyes were almost starting from its head. Johnstone came up first, caught the stave in air as it was about to descend again, wrenched it out of the man's hands, and hurled it over Clare's head, across the parapet and into the sea. The man fell back a step, and his face grew purple with rage. He roared out a volley of horrible oaths, in a dialect perfectly incomprehensible even to Clare, who knew Italian well. "You needn't yell like that, my good man," said Johnstone, smiling at him. The man was big and strong, and drunk. He clenched his fists, and made for his adversary, head down, in the futile Italian fashion. The Englishman stepped aside, landed a left-handed blow behind his ear, and followed it up with a tremendous kick, which sent the fellow upon his face in the ditch under the rocks. Clare looked on, and her eyes brightened singularly, for she had fighting blood in her veins. The man seemed stunned, and lay still where he had fallen. Johnstone turned to the fallen mule, which lay bleeding and gasping under the shafts, and he began to unbuckle the harness. "Could you put a big stone behind the wheel?" he asked, as Clare tried to help him. He knew that the cart must roll back if it were not blocked, for he had noticed how it stood. Clare looked about for a stone, picked one up by the roadside, and went to the back of the cart, while Johnstone patted the mule's head, and busied himself with the buckles of the harness, bending low as he did so. Clare also bent down, trying to force the stone under the wheel, and did not notice that the carter was sitting up by the roadside, feeling for something in his pocket. An instant later he was on his feet. When Clare stood up, he was stepping softly up behind Johnstone. As he moved, she saw that he had an open clasp-knife in his right hand. Johnstone was still bending down unconscious of his danger. The young girl was light on her feet and quick, and not cowardly. The man was before her, halfway between her and Brook. She sprang with all her might, threw her arms round the drunken man's neck from behind, and dragged him backward. He struck wildly behind him with the knife, and roared out curses. "Quick!" cried Clare, in her high, clear voice. "He's got a knife! Quick!" But Johnstone had heard their steps, and was already upon him from before, while the young girl's arms tightened round his neck from behind. The fellow struck about him wildly with his blade, staggering backwards as Clare dragged upon him. "Let go, or you'll fall!" Brook shouted to her.
