"As I had never despaired," says Bruce, "some way or other, of arriving at the fountains of the Nile, from which we were not fifty miles distant when we turned back at Karcagna, so I never neglected to improve every means that held out to me the least probability of accomplishing this end. I had been very attentive and serviceable to Fasil's servants while in the camp. I spoke greatly of their master; and, when they went away, gave each of them a small present for himself, and a trifle also for Fasil. They had, on the other hand, been very importunate with me, as a physician, to prescribe something for a cancer on the lip, as I understood it to be, with which Welleta Yasous, Fasil's principal general, was afflicted. "I had been advised by some of my medical friends to carry along with me a preparation of hemlock or cicuta, recommended by Dr. Stork, a physician at Vienna. A considerable quantity had been sent me from France by commission, with directions how to use it. To keep on the safe side, I prescribed small doses to Welleta Yasous; being much more anxious to preserve myself from reproach, than warmly solicitous about the cure of my unknown patient. I gave him positive advice to avoid eating raw meat, to keep to a milk diet, and drink plentifully of whey when he used this medicine. They were overjoyed at having succeeded so well in their commission, and declared before the king 'that Fasil, their master, would be more pleased with receiving a medicine that would restore Welleta Yasous to health, than with the magnificent appointments the king's goodness had bestowed upon him.' 'If it is so,' said I, 'in this day of grace I will ask two favours.' 'And that's a rarity,' says the king; 'come, out with them. I don't believe anybody is desirous you should be refused; I certainly am not; only I bar one of them--you are not to relapse into your usual despondency, and talk of going home.' 'Well, sir,' said I, 'I obey; and that is not one of them. They are these: You shall give me, and oblige Fasil to ratify it, the village Geesh, and the source where the Nile rises, that I may be from thence furnished with money for myself and servants; it shall stand me instead of Tangouri, near Emfras, and in value it is not worth so much. The second is, that when I shall see that it is in his power to carry me to Geesh, and show me those sources, Fasil shall do it upon my request, without fee or reward, and without excuse or evasion.'
