              <s>The veins after they have been discovered, and likewise the shafts and
                <lb/>
              tunnels, have names given them, either from their discoverers, as in the
                <lb/>
              case at Annaberg of the vein called “Kölergang,” because a charcoal
                <lb/>
              burner discovered it; or from their owners, as the Geyer, in Joachimstal,
                <lb/>
              because part of the same belonged to Geyer; or from their products,
                <lb/>
              as the “Pleygang” from lead, or the “Bissmutisch” at Schneeberg from
                <lb/>

              ; or from some other circumstances, such as the rich alluvials from
                <lb/>
              the torrent by which they were laid bare in the valley of Joachim. </s>
              <s>More
                <lb/>
              often the first discoverers give the names either of persons, as those of
                <lb/>
              German Kaiser, Apollo, Janus; or the name of an animal, as that of lion,
                <lb/>
              bear, ram, or cow; or of things inanimate, as “silver chest” or “ox stalls”;
                <lb/>
              or of something ridiculous, as “glutton's nightshade”; or finally, for the sake
                <lb/>
              of a good omen, they call it after the Deity. </s>
              <s>In ancient times they
                <lb/>
              followed the same custom and gave names to the veins, shafts and tunnels,
                <lb/>
              as we read in Pliny: “It is wonderful that the shafts begun by Hannibal in
                <lb/>
              Spain are still worked, their names being derived from their discoverers.

              three hundred pounds weight (of silver) per day.”
