One of the main arguments of the abolitionists was the potential for an alternative trade to that of human beings. The pro-slavery lobby described Africa as baron and not suitable for other trade. A French Traveller in the 18th century called Bue described his findings whilst travelling in Africa:

I was surprised to see the land so well cultivated; scarce a spot unimproved; the low lands divided by small canals, all sowed with rice; their beef excellent; poultry numerous. The villages that lie thick on the river show the country is well peopled... [They are] kind to strangers with whom they are fond of trading... [though] the frequent injuries done them by Europeans have led to them being suspicious and shy.
