The Lead Tree
A more modern invention, and an easier method by far than the above,
is the following:
To a piece of zinc fasten a wire, crooked in the form of the worm of a
still; let the other end of the worm be thrust through a cork. You
then pour spring water into a phial or decanter, to which you add a
small quantity of sugar of lead; thrust the zinc into the bottle, and
with the cork at the end of the wire fasten it up. In a few days the
tree will begin to grow, and produce a most beautiful effect.
