Vespasian was emperor when this pipe was made--the inscription tells that. When Ves pasian laid water-pipes of lead in the streets of Rome, he followed the example of Julius Csesar, who sent plumbers with his legions into bar barian lands. Lead pipe laid by these Roman invaders has been dug from English soil. For centuries lead's non-corrosive qualities have made it the favored metal for water-pipes. Lead gutters, pipe-heads, and leader pipes have been used for hundreds of years to carry off the rain from the roofs of buildings. Such lead work is often very beautiful and ornamental. Paint is used to decorate and preserve almost everything that is built or made, and the prin cipal factor in good paint is white-lead--made by corroding pure metallic lead and mixing it with linseed oil. Most painters simply add more linseed oil to the white-lead, in order to make the paint they use. Paint manufacturers use white-lead, in varying quantities, in the paint they make. The quality of any paint is largely dependent on the amount of white-lead it contains, for it is the wiiite-lcad that gives to good paint its durability. Often you see a steel skeleton, a bridge, a roof, a railing that has been painted a flaming orangc-rcd. This brilliant coat is red-lead, an oxide of lead. "Save the surface and you save all" is an imperative maxim where exposed metal surfaces arc concerned, and red-lead is the most reliable protection against rust that has yet been discovered. You are surrounded by load, in your home and on your travels. There is lead in the rubber beds of your shoes, in the tires of your auto mobile, in the bearings of the -machinery that makes things for your use or transports you "Save the surface and you save all" means that paint prevents decay and ruin.
