the tractor and the body plants is run by individual motors from this electricity. In the course of time it is expected that there will be sufficient electricity to run practically the whole Highland Park plant, and we shall then have cut out our coal bill.
Among the by-products of the coke ovens is a gas. It is piped both to the Rouge and Highland Park plants where it is used for heat-treat purposes, for the enamelling ovens, for the car ovens, and the like. We formerly had to buy this gas. The ammonium sulphate is used for fertilizer. The benzol is a motor fuel. The small sizes of coke, not suitable for the blast furnaces, are sold to the employees—delivered free into their homes at much less than the ordinary market price. The large-sized coke goes to the blast furnaces. There is no manual handling. We run the melted iron directly from the blast furnaces into great ladles. These ladles travel into the shops and the iron is poured directly into the moulds without another heating. We thus not only get a uniform quality of iron according to our own specifications and directly under our control, but we save a melting of pig iron and in fact cut out a whole process in manufacturing as well as making available all our own scrap.
