* *: 6 6.3 DRYSTONE MASONRY STRUCTURES
Hollows in lIisars (flat, smooth
rocks), often quite large, were used to
collect rainwater and surface runoff
directly They were surrounded by a
drystone wall and covered with a roof
to prevent evaporation or the water
becoming unusable.
These surface 'reservoirs' are called
basses and cocons, often imprecise
terms which simply refer to size,
and abeuradors when they have a
ramp and a large opening for animals
to gain access to the water.
