  "summary": "The water-powered sugar mill reached Hispaniola in the 1510s and by the 1530s the island had twenty of them and four horse-driven trapiches. Oviedo, a royal official resident there, priced one at ten to twelve thousand ducats and specified that it needed eighty to a hundred and twenty enslaved Africans working continuously. The same book records what that produced: the first slave revolt in the Americas, at Christmas 1521, and the gibbets set along the road afterwards.",

Oviedo concludes that \"de la una é de la otra forma\" the beginning of sugar in the island and in the Indies goes back to Atiença's canes.",

He values one of them — the licenciado Çuaço's on the Ocoa, with its enslaved people, cattle, gear and land — at over fifty thousand gold ducats, yielding its owner six thousand a year.",

He gives no total for the number of people enslaved on the island, no mortality figure for the mills, and no word from any enslaved person; the twenty who rose in 1521 are described only through the men who hunted them. None of that is asserted here from this source, and the counts above are counts of mills and of ducats, not of lives.",
