BOOK III.
Previously I have given much information
concerning the miners, also I have discussed the
choice of localities for mining. for washing sands,
and for evaporating waters; further, I described
the method of searching for veins. With such
matters I was occupied in the second book; now I
come to the third book, which is about veins and
stringers, and the seams in the rocks1. The
term “vein” is sometimes used to indicate canales
in the earth, but very often elsewhere by this name I have described that
which may be put in vessels2; I now attach a second significance to
these words, for by them I mean to designate any mineral substances which
the earth keeps hidden within her own deep receptacles.
