but also begs question: why sugar in particular?
At the time that the Portuguese and the Spaniards set out to establish a sugar industry on the Atlantic islands they controlled , sugar was still a luxury , a medicine , and a spice in western Europe. (Mintz, 1985, p. 30)
So rapid was the motion of the mill, and so rapid also the combustion of the dried canes or "trash" used as fuel in the boiling house that the work of the millers and firemen, though light enough in itself, was exhausting. A French writer described as "prodigious " the galloping of the mules attached to the sweeps of the mill; but "still more surprising" in his opinion was the ceaseless celerity with which the firemen kept up a full blaze of cane-trash. Those who fed the mill were liable, especially when tired or half-asleep, to have their fingers caught between the rollers. A hatchet was kept in readiness to sever the arm, which in such cases was always drawn in; and this no doubt explains the number of maimed watchmen. (Mintz, 1985, p. 50)
