few days. If they do not learn within that time they will never be of any use to us. These men are, many of them, foreigners, and all that is required before they are taken on is that they should be potentially able to do enough work to pay the overhead charges on the floor space they occupy. They do not have to be able-bodied men. We have jobs that require great physical strength—although they are rapidly lessening; we have other jobs that require no strength whatsoever—jobs which, as far as strength is concerned, might be attended to by a child of three.
It is not possible, without going deeply into technical processes, to present the whole development of manufacturing, step by step, in the order in which each thing came about. I do not know that this could be done, because something has been happening nearly every day and nobody can keep track. Take at random a number of the changes. From them it is possible not only to gain some idea of what will happen when this world is put on a production basis, but also to see how much more we pay for things than we ought to, and how much lower wages are than they ought to be, and what a vast field remains to be explored. The Ford Company is only a little way along on the journey.
A Ford car contains about five thousand parts—that is counting screws, nuts, and all. Some of the parts are fairly bulky and others are almost the size of watch parts. In our first assembling we simply started to put a car together at a spot on the floor and workmen brought to it the parts as they were needed in exactly the same way that one builds a house. When we started to make parts it was natural to create a single department of the factory to make that part, but usually one workman performed all of the operations necessary on a small part. The rapid press of production made it necessary to devise plans of production that would avoid having the workers falling over one another. The undirected worker spends more of his time walking about for materials and tools than he does in working; he gets small pay because pedestrianism is not a highly paid line.
