either skilled or unskilled; we had moulders and we had labourers. Now we have about five per cent. of thoroughly skilled moulders and core setters, but the remaining 95 per cent. are unskilled, or to put it more accurately, must be skilled in exactly one operation which the most stupid man can learn within two days. The moulding is all done by machinery. Each part which we have to cast has a unit or units of its own—according to the number required in the plan of production. The machinery of the unit is adapted to the single casting; thus the men in the unit each perform a single operation that is always the same. A unit consists of an overhead railway to which at intervals are hung little platforms for the moulds. Without going into technical details, let me say the making of the moulds and the cores, and the packing of the cores, are done with the work in motion on the platforms. The metal is poured at another point as the work moves, and by the time the mould in which the metal has been poured reaches the terminal, it is cool enough to start on its automatic way to cleaning, machining, and assembling. And the platform is moving around for a new load.
