Pisania is a small village in the king of Yany’s dominions, established by British subjects as a factory for trade, and inhabited solely by them and their black servants. It is situated on the banks of the Gambia, sixteen miles above Jonkakonda. The white residents, at the time of my arrival there, consisted only of Dr. Laidley, and two gentlemen who were brothers, of the name of Ainsley; but their domestics were numerous. They enjoyed perfect security under the king’s protection, and being highly esteemed and respected by the natives at large, wanted no accommodation or comfort which the country could supply, and the greatest part of the trade in slaves, ivory, and gold was in their hands. Being now settled for some time at my ease, my first object was to learn the Mandingo tongue, being the language in almost general use throughout this part of Africa, and without which I was fully convinced that I never could acquire an extensive knowledge of the country or its inhabitants. In this pursuit I was greatly assisted by Dr. Laidley. In researches of this kind, and in observing the manners and customs of the natives, in a country so little known to the nations of Europe, and furnished with so many striking and uncommon objects of nature, my time passed not unpleasantly, and I began to flatter myself that I had escaped the fever, or seasoning, to which Europeans, on their first arrival in hot climates, are generally subject. But on the 31st of July I imprudently exposed myself to the night-dew in observing an eclipse of the moon, with a view to determine the longitude of the place; the next day I found myself attacked with a smart fever and delirium, and such an illness followed as confined me to the house during the greatest part of August. My recovery was very slow, but I embraced every short interval of convalescence to walk out, and make myself acquainted with the productions of the country. In one of those excursions, having rambled farther than usual, on a hot day, I brought on a return of my fever, and on the 10th of September I was again confined to my bed. The fever, however, was not so violent as before; and in the course of three weeks I was able, when the weather would permit, to renew my botanical excursions; and when it rained, I amused myself with drawing plants, &c., in my chamber. The care and attention of Dr. Laidley contributed greatly to alleviate my sufferings; his company and conversation beguiled the tedious hours during that gloomy season, when the rain falls in torrents; when suffocating heats oppress by day, and when the night is spent by the terrified travellers in listening to the croaking of frogs (of which the numbers are beyond imagination), the shrill cry of the jackal, and the deep howling of the hyæna, a dismal concert, interrupted only by the roar of such tremendous thunder as no person can form a conception of but those who have heard it.
