"Hit war spoutin' powerful," she answered, in her stress of excitement lapsing into the language of childhood.
"Yes, I suppose so. That is in a way a good thing in such cases, however. It automatically cleanses the wound of any infectious matter. Look, Rose," he added, as though explaining to a clinic, "see how the blood is thickening up into a clot? That is chiefly the work of what we call 'white corpuscles'—infinitely tiny little organisms whose sole purpose in life is to eat up disease germs which may get into the veins, and to hurry to the surface when there is a cut, cluster together and die, their bodies forming a wall against the wicked enemies who are always anxious to get inside the blood for the purpose of making trouble."
"I told ye 'twarnt nothin'," said Big Jerry, not without a note of relief in his voice, however. "A leetle blood-lettin' won't do me no hurt. I'll jest wind a rag eround hit, an' ..."
"Not so fast," laughed Donald. "In all probability 'a rag just wound round it' would do the business, for your blood is apparently in first-class condition, with its full share of the red corpuscles; but you might just as well have the benefit of the hospital corps since we are on the ground. The red corpuscles," he added, addressing Smiles, "are the other good little chaps who continually go hurrying through the body, feeding it with oxygen and making it strong. Run into the house and get my 'first aid' kit, from my knapsack, child. You'll remember it when you see it, for I had to dig it out the very first time that I saw you."
The girl hurried cabinwards, fleet as the wind, and, as the two men sat down on a woodpile to wait for her, Donald had an opportunity to take note of his ludicrously inadequate costume.
It seemed little more than a minute before Rose returned with his kit, but it was not brought by a mountain maid. In that almost incredibly short time the child had changed her gingham dress for the immaculate costume of a trained nurse, and the transformation in apparel had been accompanied by one in mien no less noticeable. Dainty and fair as a white wild rose she was, yet seriously businesslike in expression. Donald was startled for a moment. It came to his mind that he was looking upon a vision of the years to come, and the picture caused his heart to beat a little faster; but, although the light of appreciation shone in his eyes, his only comment was, "Are your hands as clean as that dress?"
"Yes, doctor."
"Now how the deuce did she come to use that stereotyped response?" he wondered; then said, aloud, "Then undo that roll of gauze bandage and tear off a piece about six feet long ... be careful! Don't let it touch the ground."
Then he immediately gave his attention to Big Jerry, and smiled with professional callousness as he caught the giant's wince when the antiseptic fluid which he poured on the wound started it smarting.
"Now for your first lesson in the scientific application of a bandage, Smiles," he said.
