Large production would mean that he could purchase his raw materials at very low prices; high wages meant that he could get the efficient labor which was demanded by his rapid fire method of campaign.
It was necessary to plan the making of every part to the minutest detail, to have each part machined to its exact size, and to have every screw, bolt, and bar precisely interchangeable.

About the year 1907 the Ford factory was systematized on this basis.

In that twelvemonth it produced 10,000 machines, each one the absolute counterpart of the other 9999.

American manufacturers until then had been content with a few hundred a year! From that date the Ford production has rapidly increased; until, in 1916, there were nearly 4,000,000 automobiles in the United States--more than in all the rest of the world put together--of which one-sixth were the output of the Ford factories.

Many other American manufacturers followed the Ford plan, with the result that American automobiles are duplicating the story of American bicycles; because of their cheapness and serviceability, they are rapidly dominating the markets of the world.
