Marbella plantation of Mr Grevigny was well constructed. 
The expense of a good sugar-mill is considerable. Laborde — 
states that some mills cost 100,000 livres tournois, or upwards 
of L.4000 Sterling. 
The expressed juice of the cane is conveyed from the mill 
in wooden gutters, lined with lead or copper, to the boiling- 
house. The best works have a series of three boilers, in which 
the juice undergoes purification, and hence are called clarifiers, 
These are of different sizes, placed in brick-work, and each is 
heated by a separate fire. In the first copper, milk of lime is 
added to absorb the acid always existing in cane-juice; the 
heat is raised nearly to the point of ebullition, and then the 
fire is cut off by adamper. A thick scum has by this time 
collected on the surface, which is allowed to accumulate for 
an hour, when the subjacent clear liquid is drawn off by a 
cock on the lower part of the clarifier. The liquid is next 
conveyed to the second boiler, when it is subjected to a boil- 
ing heat, to inspissate the juice ; but lime-water is added in 
this step of the process, and the scum which rises is laded. off 
repeatedly. The clarified juice is usually subjected to a simi- 
lar process in a third clarifier, whence it passes into the prin- 
cipal boiler, or feache, as it is termed by our West Indian 
sugar-planters. Here it undergoes its final evaporation ; and 
when judged to be sufficiently concentrated for crystallization, 
the syrup is laded off into wooden coolers of about 10 inches 
deep, with a surface of 20 or 30 square feet. Here it granu- 
lates ; and the imperfect crystals thus obtained are removed 
to the curing-room and drained, just as in the manufacture of: 
West Indian sugar. In the sugar-works of M. Grevigny at 
Marbella, the sugar is also clayed and baked, as in our re- 
fineries ; and the quality of both their muscovado and loaf 
sugar is excellent. 
The following particulars, extracted from the books of my 
excellent friend the late William Kirkpatrick, Esq. of Malaga, 
give an account of the state of that large establishment in 
1806, when he was manager. The plantation at Marbella be- 
came the property of his father-in-law, M. Grevigny, in 1800, 
under a royal charter. As these documents refer to a period 
previous to the operation of the famous Berlin and Milan de-
