1mass of the mountains in order
that the owners may lay out their plans, and
that their workmen may not encroach on other people's possessions. The
surveyor either measures the interval not yet wholly dug through, which
lies between the mouth of a tunnel and a shaft to be sunk to that depth, or
between the mouth of a shaft and the tunnel to be driven to that spot which
lies under the shaft, or between both, if the tunnel is neither so long as to
reach to the shaft, nor the shaft so deep as to reach to the tunnel; and thus
on both sides work is still to be done. Or in some cases, within the tunnels
and drifts, are to be fixed the boundaries of the meers, just as the Bergmeister
has determined the boundaries of the same meers above ground.16

Each method of surveying depends on the measuring of triangles.
A
small triangle should be laid out, and from it calculations must be made
regarding a larger one. Most particular care must be taken that we do not
deviate at all from a correct measuring; for if, at the beginning, we are drawn
