The day was hot and stormy, and the sun was several times obscured by dark and thick clouds. In the evening a violent south wind rose, followed by thunder and lightning. Thick black clouds gathered on the summit of the mountains, surrounding the beautiful plain of Kankan-Fodéa. About eight in the evening, a heavy rain set in, and lasted all night. I could not sleep, and passed the time in reflecting on the difficulties which I should have to surmount, in crossing a country intersected by rivers and large streams, which in this season overflow their banks. I travelled on foot, for the appearance of humility which I had imposed upon myself during this journey did not allow me to purchase an animal to ride on, which would have awakened the cupidity of the various tribes that I had to visit; thoroughly persuaded that the success of my undertaking depended on this appearance of poverty. The old schoolmaster fell ill, and I became his physician. He had a fever, and I gave him some doses of sulphate of quinine, and, afterwards, a dose of salts as a purgative; I then advised him to buy a fowl to make broth, seasoned with brettes, a sort of herb which grows in that country, but the poor old man had not the means of buying a fowl. I begged Ibrahim to make him a present of one, but he replied coldly that he had none, though I saw twenty running about in his yard. I gave the old man five tobacco leaves, to purchase a fowl, which Ibrahim found for that price; he gave it to one of his women to cook, and the schoolmaster speedily recovered. I had given Ibrahim some doses of jalap, which he had asked me for, and though nothing ailed him, he took a dose of it, with the view of having a claim on some of the broth, which he saw preparing for my patient. It was rumoured among the inhabitants that I possessed medicines for all sorts of disorders, and I was much importuned and harassed for them. Some had ulcers on the arms or legs, others, fever and bowel complaint; I was teazed all day long by demands for medicine. To cure the ulcers, I washed them with a caustic, and then dressed them with lint; and to those suffering from fever I administered a few doses of quinine, and directed a regimen, which did not always please my patients. To act up to the character of doctor, I sometimes grew angry, and threatened to abandon to their fate those who did not follow my directions. The only medicines I had were those few with which the English doctors of Sierra-Leone had been kind enough to furnish me, and I was anxious to keep them for myself, presuming that I might need them; but the Mandingoes imagined that my stock was inexhaustible, and that it might be beneficially employed in all kinds of distempers. They were continually asking me for physic, and though I was obliged to refuse them, yet they continually renewed their applications, observing that they were Musulmans as well as I, and that no Musulman ought to withhold a service which he can perform.
