The Kid sat up blinking. "I'm very sorry," he said after a moment. "Did I upset the beer?" "You did--all over me," laughed the Doctor. "Get your boots off and turn in." "I'm so cursed sleepy." The Kid was removing his sodden puttees. "I've walked, and walked, and I'm just about----" He straightened himself in his chair, and as he did so the words died away on his lips. With a peculiar fixed look he stared past the Doctor into the corner of the dug-out. "My God!" he whispered at last, "what are you doing here?" A sudden silence settled on the mess, and instinctively everybody, including the Doctor, glanced towards the corner. Then the Doctor turned once more to the boy, and his glance was the glance of his profession. "What's the matter, Kid?" His tone was abrupt, even to curtness. "Did you think you saw something?" "I thought--I thought----" The boy passed his hand over his forehead. "I'm sorry--I must have been dreaming. It's gone now. I suppose I'm tired." But his eyes still searched the dug-out fearfully. "What did you think you saw?" asked the Doctor shortly. "I thought I saw----" Once again he stopped; then he laughed a little shakily. "Oh! it doesn't matter what I thought I saw. Damn it! I'm tired; let me turn in." The Doctor's eye met the Company Commander's over the table, and he shrugged his shoulders slightly. "Dead beat." His lips framed the words, and he returned to the contemplation of his cigar, which was not doing all that a well-trained cigar should. The Kid stood up and glanced round the mess at his brother officers a little shamefacedly; only to find them engrossed--a trifle ostentatiously--in their own business. "I'm sorry, you fellows," he blurted out suddenly. "Forgive me being such a fool; I suppose I'm a bit tired." The Doctor took him firmly by the arm, and led him towards the bed. "Look here, old soul," he remarked, "if you wish to avoid the wrath of my displeasure, you will cease talking and go to bed. Every one knows what it is to be weary; and there's only one cure--sleep." The Kid laughed and threw himself on the bed. "Jove!" he muttered sleepily; "then it's a pleasant medicine, Doctor dear." He pulled a blanket over his shoulders; his head touched the pillow; his eyes closed; and before the Doctor had resumed his seat the Kid was asleep. * * * * * *
