Sometime in the night the tumult in his brain and heart subsided and he fell into a profound sleep. The next thing he knew the kindly roughness of his comrades wakened him with shakes and wet sponges flying through the air, and he opened his consciousness to the world again and heard the bugle blowing for roll call. Another day had dawned grayly and he must get up. They set him on his feet, and bantered him into action, and he responded with his usual wit that put them all in howls of laughter, but as he stumbled into place in the line in the five o'clock dawning he realized that a heavy weight was on his heart which he tried to throw off. What did it matter what Ruth Macdonald did with her life? She was nothing to him, never had been and never could be. If only he had not written that letter all would now be as it always had been. If only she had not written her letter! Or no! He put his hand to his breast pocket with a quick movement of protection. Somehow he was not yet ready to relinquish that one taste of bright girl friendliness, even though it had brought a stab in its wake. He was glad when the orders came for him and five other fellows to tramp across the camp to the gas school and go through two solid hours of instruction ending with a practical illustration of the gas mask and a good dose of gas. It helped to put his mind on the great business of war which was to be his only business now until it or he were ended. He set his lips grimly and went about his work vigorously. What did it matter, anyway, what she thought of him? He need never answer another letter, even if she wrote. He need not accept the package from the post office. He could let them send it back--refuse it and let them send it back, that was what he could do! Then she might think what she liked. Perhaps she would suppose him already gone to France. Anyhow, he would forget her! It was the only sensible thing to do. Meanwhile the letter had flown on its way with more than ordinary swiftness, as if it had known that a force was seeking to bring it back again. The Y.M.C.A. man was carried at high speed in an automobile to the nearest station to the camp, and arrived in time to catch the Baltimore train just stopping. In the Baltimore station he went to mail the letter just as the letter gatherer arrived with his keys to open the box. So the letter lost no time but was sorted and started northward before midnight, and by some happy chance arrived at its destination in time to be laid by Ruth Macdonald's plate at lunch time the next day.
