William Garden Blaikie,
The Personal Life of David Livingstone…
“ All the country we traveled through is capable of growing cotton and sugar, and the people now cultivate a good deal. They would grow much more if they could only sell it. At present we in England are the mainstay of slavery in America and elsewhere by buying slave-grown produce. Here there are hundreds of miles of land lying waste, and so rich that the grass towers far over one's head in walking. You cannot see where the narrow paths end, the grass is so tall and overhangs them so. If our countrymen were here they would soon render slave-buying unprofitable. ”
