All these types of plough are virtually hoes pulled through the ground, breaking but not inverting the soil.
The autumnal subsidence of the river was followed by shallow ploughing performed by oxen yoked to clumsy wooden ploughs, the clods being afterwards levelled with wooden hoes by hand.
Hoes also help to break up hard soil and keep it ready to soak up as much water as possible when it rains.
Iron is smelted by the natives, who, especially amongst the Hausas, are very clever smiths, and manufacture fine lances and arrow heads, knives and swords, and also hoes.
