To make a mould for a pencil, or a rod which may be cut into short lengths for slugs, roll up a piece of paper as shown in fig. 2, and bury it in the earth : reeds, when they are to be obtained, make a stronger mould than paper.

To cast a lamp, a bottle, or other hollow article, use a cylinder of paper, buried in the ground, as in fig. 3, and hold a stick fast in the middle, while the lead is poured round.

Loose, shaky articles often admit of being set to rights, by warming the joints and pouring a little melted lead into the
