On this plantation found that the vein had been opened
eighty years ago. by of the British settlers, before

observations in my travels, we'll in tracing the
mineral veins to great depths both in Europe, Anne

enables me to form more correct opinion of the
geological formation and the earth where these

nation from theory alone and have taken every pre-
caution that nav be as possible in my
Mines and Of getting true method Of bringing them into
productive state Of operation, upon systematic plan,
with little expense possible. But as it is matter of
such great Importance you will doubt make every
allowance for will therefore in the first place give
description of the shaft and the present state Of the
mine.
