"'What are the knives for?'

"'They use the knives for cutting off limbs. Twice have I seen this done, for I was travelling with a learned hakim, who was searching the tombs for relics. In one case a great stone fell on a man's foot, and smashed it, and the hakim took it off at the ankle. In another case a man had been badly wounded, by a bullet in the arm. He was not one of our party but, hearing of the hakim's skill, he had made a journey of three days to him. The wound was very bad, and they said it was too late to save the arm, so they cut it off above the elbow.'

"'And they lived?'

"'Yes, they both lived.'

"'Could you do that?'

"I shook my head. 'It requires much skill,' I said. 'I saw how it was done, but to do it one's self is very different. If there was a man who must die, if an arm or a leg were not taken off, I would try to save his life; but I would not try, unless it was clear that the man must die if it were not done.

"But you are learned men, hakims, and if you will take me as your assistant, I will show you how the white doctors take out balls, and, if there is no other way, cut off limbs; and when I have once shown you, you will do it far better than I.'

"The two men seemed much pleased. It was evident to them that, if they could do these things, it would widely add to their reputation.

"'It is good,' they said. 'You shall go round with us, and see the wounded, and we will see for ourselves what you can do. Will you want this chest carried?'

"'No,' I said. 'I will take these instruments with me. Should it be necessary to cut off a limb, to try and save life, I shall need the knives, the saw, and this instrument, which I heard the white hakim call a tourniquet, and which they use for stopping the flow of blood, while they are cutting. There are other instruments, too, that will be required.'"
