To-day it was as if with each intake of breath the sweet air reached for the first time the most remote corners of his lungs. He had never before had air enough. The sunshine reached to the marrow of his bones. Muscles that had lagged became vibrant. He could hardly keep his feet upon the ground. He would have liked to run; to keep on running mile after mile. He wondered when he would tire. He had a feeling that he could never tire. His back and arm muscles ached for action. He would have enjoyed a rough-and-tumble fight with some impudent fellow vagabond of the road. Marjory walked by his side in silence. That was all he asked--simply that she should be there on the left, dependent upon him. Here was the nub of the matter. Always before she had been able to leave him if she wished. She had married him upon that condition. There had never been a moment, until now, when he had not been conscious of the fact that he was in no way necessary to her. The protection against Teddy and the others was merely a convenience. He had been able to save her from annoyance, that was all. At any time on that ride from Paris she could have left him and gone on her way quite safely. At Nice, that was just what she had done. It was to save her from the annoyance of himself that he had finally gone away. Had he been really needed, that would have been impossible. But he knew that she could get along without him as she did. Then when Peter had gone it was more because he needed her than because she needed him that he had returned. Down deep in his heart he knew that, whatever he may have pretended. She was safe enough from everything except possible annoyance. With plenty of gold at her command, there was nothing that he could buy for her that she could not buy for herself. Now she had no gold--except one louis d'or. He was almost jealous of that single piece. He would have been glad if she lost it. If he had seen it drop from her bag, he would have let it lie where it fell. She was merely a woman now. The muscles in her arms and legs were not strong. Because of that she could not leave his side, nor order him to leave. She must look to him to fight for her if fighting were necessary. She must look to him to put his strong arm about her and help her if she grew weary. She must look to him to provide her with food and shelter for the night. Physically she was like a child out here on the open road. But he was a man. He was a man because he had something to protect. He was a man because he was responsible for some one besides himself. It was this that the other half of him had been craving all these years. It was this that completed him.
