In 1767, an epidemic broke out on board a crowded emigrant vessel sailing from Belfast to South Carolina; the unscrupulous owners had packed 450 people into its hold and more than 100 died at sea. Another ship bound from Belfast to Philadelphia ran out of food in mid-passage. Forty-six passengers starved to death; the survivors were driven to cannibalism and some even consumed the flesh of their own families. The transatlantic journey became more dangerous in the eighteenth century than it had been in the seventeenth. Mortality in ships sailing from North Britain approached that in the slave trade.17
