The thought appealed at once to the kindly feelings of the boys and they all instantly volunteered, but Jack, as the next in order on the sentry list, claimed the privilege of relieving Ed.

When Ed came in he first of all wanted to hear whether or not the man he had shot in the darkness was likely to die of his wounds.

The Doctor promptly reassured him on that point.

Then Ed said:

"Well, Doctor, if you are quite through with him, suppose you look at a little scratch that he gave me. I didn't want to say anything about it, but maybe it is better to have it attended to."

The Doctor turned instantly and began stripping off the boy's clothing. He found that a bullet, striking him in the left side, had passed between two ribs, almost penetrating the hollow of the lower chest, but without quite doing so. It was one of those wonderful vagaries of bullet wounds that would kill in ninety-nine cases out of a hundred, but which in the hundredth case do a minimum of damage.

The Doctor having satisfied himself that no vital organ had been touched, carefully disinfected the wound and swathed it in bandages. As he did so he said to the boy:

"Why didn't you tell us at the start, Ed, that you were wounded?"

"Well you see," said Ed, "I was more concerned about the other fellow. It isn't a pleasant thing to kill a man, even when you've got to do it in self defence. So as I knew by his groans that he was worse hurt than I was, I didn't say anything about what his bullet had done till you were through with the job of dressing his wounds."

"Will you permit me to remark," said the Doctor, "quite casually and in parentheses as it were, that you, Ed Parmly, are a hero? I haven't met a great many heroes in my time, but you are one of the few. Now you're going to bed, and I'm going to play tyrant over you till this wound gets well. But upon my word, I never knew two shots fired in darkness that did their work so effectively as yours and that mountaineer's did."
