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 hyaena, 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.

The country itself being an immense level, and very generally covered with wood, presents a tiresome and gloomy uniformity to the eye; but although Nature has denied to the inhabitants the beauties of romantic landscapes, she has bestowed on them, with a liberal hand, the more important blessings of fertility and abundance.  A little attention to cultivation procures a sufficiency of corn, the fields afford a rich pasturage for cattle, and the natives are plentifully supplied with excellent fish, both from the Gambia river and the Walli creek.

The grains which are chiefly cultivated are—­Indian corn (zea mays); two kinds of holcus spicatus, called by the natives soono and sanio; holcus niger, and holcus bicolor, the former of which they have named bassi woolima, and the latter bassiqui.  These, together with rice, are raised in considerable quantities; besides which, the inhabitants in the vicinity of the towns and villages have gardens which produce onions, calavances, yams, cassavi, ground nuts, pompions, gourds, water-melons, and some other esculent plants.

I observed likewise, near the towns, small patches of cotton and indigo.  The former of these articles supplies them with clothing, and with the latter they dye their cloth of an excellent blue colour, in a manner that will hereafter be described.

In preparing their corn for food, the natives use a large wooden mortar called a paloon, in which they bruise the seed until it parts with the outer covering, or husk, which is then separated from the clean corn by exposing it to the wind, nearly in the same manner as wheat is cleared from the chaff in England.  The corn thus freed from the husk is returned to the mortar and beaten into meal, which is dressed variously in different countries; but the most common preparation of it among the nations of the Gambia is a sort of pudding which they call kouskous.  It is made by first moistening the flour with water,
