We passed our Sunday on a sugar estate at the hospitable mansion of a planter from the United States about fifteen miles from Matanzas. The house stands on an eminence, once embowered in trees which the hurricanes have leveled, overlooking a broad valley, where palms were scattered in every direction; for the estate had formerly been a coffee plantation. In the huge buildings containing the machinery and other apparatus for making sugar, which stood at the foot of the eminence, the power of steam, which had been toiling all the week, was now at rest. As the hour of sunset approached, a smoke was seen rising from its chimney, presently pufis of vapor issued from the engine, its motion began to be heard, and the negroes, men and women, were summoned to begin the work of the week. Some feed the fire under the boiler with coal; others were seen rushing to the mill with their arms full of the stalks of the cane, freshly cut, which they took from a huge pile near the building; others lighted fires under a row of huge cauldrons, with the dry stalks of cane from which the juice had been crushed by the mill. It was a spectacle of activity such as I had not seen in Cuba. The sound of the engine was heard all night, for the work of grinding the cane, once begun, proceeds day and night, with the exception of Sundays and some other holidays. I was early next morning at the mill. A current of cane juice was flowing from the mill in a long trunk to a vat in which it was clarified with lime; it was then made to pass successively from one seething cauldron to another, as it obtained a thicker consistence by boiling. The negroes, with huge ladles turning on pivots, swept it from cauldron to cauldron, and finally passed it into a trunk, which conveyed it to shallow tanks in another apartment, where it cooled into sugar. From these another set of workmen scooped it up in moist masses, carried it in buckets up a low flight of stairs, and poured it into rows of hogsheads pierced with holes at the bottom. These are placed over a large tank, into which the moisture dripping from the hogsheads is collected and forms molasses.
