above outlined. The most economical manufacturing of the future will be that in which the whole of an article is not made under one roof—unless, of course, it be a very simple article. The modern—or better, the future—method is to have each part made where it may best be made and then assemble the parts into a complete unit at the points of consumption. That is the method we are now following and expect to extend. It would make no difference whether one company or one individual owned all the factories fabricating the component parts of a single product, or whether such part were made in our independently owned factory, if only all adopted the same service methods. If we can buy as good a part as we can make ourselves and the supply is ample and the price right, we do not attempt to make it ourselves—or, at any rate, to make more than an emergency supply. In fact, it might be better to have the ownership widely scattered.
I had been experimenting principally upon the cutting down of weight. Excess weight kills any self-propelled vehicle. There are a lot of fool ideas about weight. It is queer, when you come to think of it, how some fool terms get into current use. There is the phrase "heavyweight" as applied to a man's mental apparatus! What does it mean? No one wants to be fat and heavy of body—then why of head? For some clumsy reason we have come to confuse strength with weight. The crude methods of early building undoubtedly had much to do with this. The old ox-cart weighed a ton—and it had so much weight that it was weak! To carry a few tons of humanity from New York to Chicago, the railroad builds a train that weighs many hundred tons, and the result is an absolute loss of real strength and the extravagant waste of untold millions in the form of power. The law of diminishing returns begins to operate at the point where strength becomes weight. Weight may be desirable in a steam roller but nowhere else. Strength has nothing to do with weight. The mentality of the man who does things in the world is agile, light, and strong. The most beautiful things in the world are those from which all excess weight has been eliminated. Strength is never just weight—either in men or
