The banks of the river Ofo are low, not being more than three feet above the surface of the water. We remained on the bank of this river till we dried our clothes. Here we also cooked some provisions, and cleaned our guns. We then again resumed our journey; and, at twenty-eight miles, arrived at the large town of Kasso-Kano. This town is well built, and the houses well thatched. There are three market-days in the week here: this happened to be one of them, and though the afternoon was far advanced, the dealers were busily employed. Slaves were abundant, and many parents were publicly offering their children for sale, numbers of them not more than eleven or twelve years of age. They showed their slaves off, and purchasers scrutinized them with as much care as our horse-dealers at an English fair. Here the women are modest and handsome, the men generally tall, thin, and sinewy. They are apparently very jealous of their women, and naturally covetous and suspicious, and moreover great thieves. The chief is a shrewd, cunning fellow, and, like all others in the same office, seems to monopolize in a great measure the greater portion of the trade in all articles of consumption. The hills in this neighbourhood abound with iron, and another mineral substance resembling coal, but this mineral is not so abundant: it is probably antimony. I have forgotten its name. It was brought on board in small pieces (the largest not more than half an inch square) during the late Niger expedition, but it was extremely dear. It is used as and considered an infallible cure for inflammation in the eye, by merely rubbing it round it.
