François described one this way: “It is a mill which grinds grain and is moved by the convicts. 18 men continually go up a wheel and their weight makes the wheel and the mill go.
Lūk, kā to aprakstīja Fransuā: ” Tās ir dzirnavas, kurās maļ graudus un kuras darbina katordznieki. Dzirnavu ratā 18 vīri nemitīgi kāpj augšup, ar savu svaru likdami ratam griezties un dzirnavām darboties.
