The chapter of casualties was enough to curdle the blood of any one but a doctor—a doctor with perfect nerve and training. All kinds of violent exertions had been used to save the vessels, and men had toiled with sacks sewn round their boots to avoid slipping on a glassy surface which froze like a mirror whenever it was exposed for a few seconds to the air between the onrushes of successive waves. Ferrier carried his life in his hand for three days as he went from vessel to vessel; the sea was unpleasant; the risk involved in springing over icy bulwarks on to slippery decks was miserable, and the most awkward operations had to be performed at times when it needed dexterity merely to keep a footing. One man had the calf of his leg taken clean away by a topmast which came down like a falling spear; the frost had caught the desperate wound before Ferrier came on the scene, and the poor mortal was near his last. The young man saw that the leg must go; he had never ventured to think of such a contingency as this, and his strained nerve well-nigh failed him. A grim little conversation took place in the cabin between the skipper, the doctor, and the patient. I let the talk explain itself, so that people may understand that Ferrier's proposed hospital was not demanded by a mere faddist. The man was stretched on a moderately clean tablecloth laid on the small open space in the close dog-hutch below; a dull pallor appeared to shine from underneath, and glimmered through the bronze of the skin. He was sorely failed, poor fellow. The skipper stood there—dirty, unkempt, grim, compassionate. Ferrier put away a bucket full of stained muslin rags (he had tried his best to save the limb), and then he said softly, "Now, my son, I think I can save you; but you must take a risk. We can't send you home; I can't take you with me until we get a turn of smooth water; if I leave you as you are, there is no hope. Do you consent to have the leg taken off?"

"Better chance it, Frank, my boy. I dursn't face your old woman if I go home without you."

"Will it give me a chance? Can I stand the pain?"

"You'll have no pain. You'll never know, and it all depends upon afterwards."

"I stand or fall with you, doctor. I have some little toebiters at home I don't want to leave yet."

"Very good. Now, skipper, stand by him till I come back; I have some things to bring."

Two wild journeys had to be risked, but the doctor's luck held, and he once more came on that glassy deck. Sharply and decisively he made his preparations. "Have you nerve enough to assist me, skipper?"

"I'll be as game as I can, doctor."

"Then kneel here, and take this elastic bag in your hand; turn this rose right over my hands as I work, and keep the spray steadily spirting on the place. You understand? Now, Frank, my man, when I put this over your face, take a deep breath."
