Prospecting for Lead:
How Difficult Was It to Locate Lead?
Veins which occurred near the surface were the easiest to work, but were likely to be hidden by soil and vegetation.
Veins could often be seen in places where the solid rock was exposed, such as cliffs and scars, or in stream bottoms.
Artificial streams called prospecting hushes were also used to remove surface soil and vegetation and locate veins.
These hushes took water from a stream or a dam and directed it across the presumed line of the vein.
Historical texts mention the use of dowsing, and the way that frost formed on vegetation over the vein. It may have
been possible to locate veins by particular types of plant which are tolerant of lead contamination.
