Well, the British used runaways as mercenaries and then gave them land to farm. I think that is a quantum difference from how the Americans used slaves.
Hmm: Here’s some information about Slavery in Guyana:
http://www.guyana.org/features/guyanastory/chapter26.html
The slaves also obtained a clothing allowance roughly every year. The men received a coarse woollen jacket, a hat, about six yards of cotton, and a piece of canvas to make a pair or two of trousers. Women received the same allowance as the men, but children received none. The children remained naked until they were about nine years old, or were given cast-off clothing that their parents managed to find or were able to purchase.
The work day of the slaves began even before day-break. They were marched to the fields by slave drivers who controlled them with whips. Slave drivers were themselves slaves who were specially selected by the White plantation owner. A White overseer supervised the entire operation. With farm implements allocated to them, the slaves worked in the fields and were occasionally lashed by the slave drivers if they attempted to idle. Around the middle of the day they were given an hour’s break to refresh themselves. The work day ended at about eight in the evening. But the slaves who worked at the sugar mills during the grinding season were forced to work even longer hours.
Slaves were punished in various ways. For striking a White man, a hand could be cut off. But whipping was the most common form of punishment and this was inflicted liberally and in the most cruel form. The whipping was done by a slave driver under the watchful eye of a while overseer, and it was not unusual for the victim to be beaten to death."
And here’s some information about slavery in Jamaica.
“As elsewhere in the Americas, the right of masters in Jamaica to punish slaves was enshrined in law, and the violence that sustained slavery went far beyond whipping. Punishments could include amputation, disfiguring, branding and more. Slaves could also be put to death – a penalty most often enforced during the aftermath of rebellions. And they were rarely killed quickly. The torturous executions meted out to those who led uprisings or who were accused of collaborating in rebellious plots provide some of the most lurid”
examples of human cruelty on record.
