This mid-nineteenth century imperial travel narrative by the British consul at Mozambique describes the arrival of principally Spanish and Portuguese slave ships at Mozambique in the late 1850s. He makes reference to the French labour emigration scheme to the Indian Ocean colonies as a new kind of slave trading, which has "caused a renewal of all the horrors" of the trade "which England has, for more than half a century, been endeavouring to put an end to" (I, 117), and also suggests that British capital may have been involved. According to McLeod, the "blight of slavery is on the whole district" (I, 184), and he is horrified by the treatment of the domestic slaves in the Portuguese colony.
A letter by G. W. Duncan, a British trader, first published in the Natal Mercury (June 1857) describing his observations of the East Africa slave trade is reprinted by McLeod (I, 120-25).
