"To form just idea of the unhealthiness of the climate, it will be necessary to conceive a country extending three hundred leagues East, and more to the North and South. Through this country several large rivers empty themselves into the sea; particularly the Sanaga, Gambia and Sherbro; these, during the rainy months, which begin in July and continue till October, overflow their banks, and lay the whole flat country under water; and indeed, the very sudden rise of these rivers is incredible to persons who have never been within the tropicks, and are unacquainted with the violent rains that fall there. At Galem, nine hundred miles from the mouth of the Sanaga, I am informed that the waters rise one hundred and fifty feet perpendicular, from the bed of the river. This information I received from a gentleman, who was surgeon's mate to a party sent there, and the only survivor of three captains command, each consisting of one captain, two lieutenants, one ensign, a surgeon's mate, three serjeants, three corporals, and fifty privates. "When the rains are at an end, which usually happens in October, the intense heat of the sun soon dries up the waters which lie on the higher parts of the earth, and the remainder forms lakes of stagnated waters, in which are found all sorts of dead animals. These waters every day decrease, till at last they are quite exhaled, and then the effluvia that arises is almost insupportable. At this season, the winds blow so very hot from off the land, that I can compare them to nothing but the heat proceeding from the mouth of an oven. This occasions the Europeans to be sorely vexed with bilious and putrid fevers. From this account you will not be surprized, that the total loss of British subjects in this island only, amounted to above two thousand five hundred, in the space of three years that I was there, in such a putrid moist air as I have described." ] [Footnote B: James Barbot, agent general to the French African company, in his account of Africa, page 105, says, "The natives are seldom troubled with any distempers, being little affected with the unhealthy air. In tempestuous times they keep much within doors; and when exposed to the weather, their skins being suppled, and pores closed by daily anointing with palm oil, the weather can make but little impression on them."]
