Read the passage from Sugar Changed the World. For an African, whether you were sent to the Caribbean or South America, you were now part of the sugar machine. And it did not much matter where your ship landed. You could be working the fertile fields of Brazil or the hills of Jamaica; the brutal cycle of making sugar was much the same.

If the terrain was not too rocky or hilly, you might be part of a group of slaves who drove teams of oxen to draw plows across the fields. On rougher ground, you were sent out to clear a space five inches deep and five feet square. Then you dug holes for the cane shoots in the cleared squares. You needed to work quickly and without stopping. Overseers watched closely to make sure of that, beating slaves who did not carve out at least twenty-eight holes an hour on one French island. The painstaking work had just one aim: to plant a crop that would end up taking the life of every worker who touched it. As Equiano explained, the sugar slaves could hardly rest even when their day was done.
