is now there. This plant is located on the river on the outskirts of Detroit and the property covers six hundred and sixty-five acres—enough for future development. It has a large slip and a turning basin capable of accommodating any lake steamship; a short-cut canal and some dredging will give a direct lake connection by way of the Detroit River. We use a great deal of coal. This coal comes directly from our mines over the Detroit, Toledo and Ironton Railway, which we control, to the Highland Park plant and the River Rouge plant. Part of it goes for steam purposes. Another part goes to the by-product coke ovens which we have established at the River Rouge plant. Coke moves on from the ovens by mechanical transmission to the blast furnaces. The low volatile gases from the blast furnaces are piped to the power plant boilers where they are joined by the sawdust and the shavings from the body plant—the making of all our bodies has been shifted to this plant—and in addition the coke "breeze" (the dust in the making of coke) is now also being utilized for stoking. The steam power plant is thus fired almost exclusively from what would otherwise be waste products. Immense steam turbines directly coupled with dynamos transform this power into electricity, and all of the machinery in
