Soon there were industries within industries at the Rouge. Blast furnaces and coke ovens were fed with coal, iron ore, and limestone brought to the plant from Ford mines by Ford railroads and Ford freighters. There were glass mills, paper factories, tire plants, and saw mills. The products of these mills and plants flowed into the assembly lines not only at the Rouge plant but at other assembly plants scattered all over the world. The production of Ford cars rose to gigantic proportions. In 1914, the year that Henry Ford and his engineers began to plan for the plant on the Rouge, over two hundred thousand automobiles were produced. But in the year 1923, over two million model T’s rolled off the assembly lines. In 1925, nearly ten thousand Fords were completed in a single day in Ford plants. The world had never before seen such an industrial giant as the one Henry Ford and his son Edsel had created. The automobiles produced by Ford and his competitors did more than replace the horse and carriage. They changed the daily habits of Americans everywhere. No longer did families in the cities have to live in the shadow of the factories where the head of the household was employed. Some families moved to the “suburbs” many miles away from stores and industries, while other city dwellers left the urban areas completely to live in the country. On the other hand, those who had always lived on farms could come to the city with ease in automobiles. The farmers were able to enjoy the advantages of the city. Thus it was that Americans moved about in a way unheard of years before. As travel increased, dirt roads were replaced by the super-highways. Service stations, motels, and garages dotted the newly-built concrete and brick roads. In the cities, people became aware of the “parking” problem, and of “traffic jams.” The increasing number of automobiles also brought death on the highways and city streets to hundreds of Americans each year. As the years went by, automobile manufacturers changed too. At first, there were dozens of makers of automobiles whose names are all but forgotten now. As the number of manufacturers decreased, the number of cars made annually by the remaining companies grew larger and larger. Eventually people talked about the “big three” of the automobile industry.
