William Henry Giles Kingston,
How Britannia Came to Rule the Waves
“ In these barracoons the slaves, when purchased, are imprisoned, till shipped on board a slave-vessel. If the barracoon be a large one, there is a centre row of piles, and along each line of piles is a chain, and at intervals of about two feet is a large neck-link, in one of which each slave is padlocked. Should this method be insufficient, two, and sometimes when the slaves appear unusually strong, three are shackled together—the strong man being placed between two others and heavily ironed; and often beaten half to death beforehand to ensure his being quiet. ”
