123 ^ Treatise oft 
only in Caverns whofe Situation is parallel to the 
Surface of the Earth, and which open towards the 
South ; and that it grows no where but upon the 
Roofs of thefe Caverns, and always with its Branches 
downwards. But a convincing Argument to the 
contrary is, that Branches of Coral are fometimes 
found upon Pitchers, Sculls, Pieces of Wood, 
Iron, Shells, and Things of the like Nature *, for 
thefe always fubfiding to the Bottom of the Sea, 
the Coral adhering to them muff neceffarily grow 
upwards. 
The Urinators in Provence , in fifhing for Coral, 
make ufe of two Machines. The one, which is 
commonly employed for getting the Coral from 
craggy Rocks, is a large wooden Crofs, with a 
heavy Ball of Lead fixed to the Centre to make it 
fink. This is fuftained by a long Rope, and a Net 
of an orbicular Form is hung to each of the Arms 
or Extremities of the Crofs. This Crofs being let 
down into the Water, when the Urinators have 
difcovered a Cavern well flocked with Coral, the 
Perfon to whom the Care of directing the Machine 
is committed, pufh'es an Arm or two of the Crofs 
into the Cavern, and fo the Coral, being entangled 
in the Nets, is broken off and drawn out of the 
W ater by Perfons who (land in Boats. 
The other Machine, whereby Coral is got from 
the deepefl Caverns, is a long Beam, to the End 
of which an Iron- Circle is fixed a Foot and Plalf 
in Diameter, bearing a reticular Sack, with two 
fuch Nets as thofe abovementioned, on each Side 
one.' This Beam is connected to the Prow and 
Stern of a Boat by two long Ropes, and being 
funk in the Water by a Ball of Lead, is diredled 
and impelled under Caverns by the Motion of the 
Boat. The Coral-Branches, growing on the Roofs 
of the Caverns, are fcraped off by the Circle of 
Iron,
