The three illustratious on page 298 are designed to representtraps set in lead pipe and show vividly the difference betweenthis material and iron piping. Lead is one of the elementary substances of which the worldis formed; it ranks with gold, silver, tin, etc., in being anunmixed metal. It melts at about 617° Fahi-enhoit, and is,bulk for bulk, lli% heavier than water (gold being I?/;; heavierand wrought iron 7i5 heavier). The tenacity of lead isextremely low, a wire Tsth of an inch breaks with a weight of Fig. 159,
