As time and the expense of transportation rather than distance were the elements that governed the distance from the heart of the city that could be used for workers’ homes, the utilization of fixed lines of traffic resulted in the city building out along main streets, trolleys and railroads. Along main lines of traffic, as between two important cities, the population began to group itself into lines.

This is the state of the distribution of population to be found in the world to-day. But the present distribution is imperfect. The trolleys carry people to the street corner but make no provision for getting them into their homes or for getting the meals on the sideboard, the book from the library to the center table, or the camphor from the drug store to the sick room.

The means of conveying the necessities of civilization is almost wholly that of rails, pipes and wires. The former is the means of transporting people and parcels, the second of liquids and gases, the third of electricity in its various forms.

These mechanical servants have been placed in the streets which were first built as roadways for carriages. In the streets, the pipes and wires must be buried beneath the pavement at great expense. Through these streets, frequently full of curves and angles which offer little trouble to the free moving horse-drawn vehicle, the rails must be bent and the cars slow down for curves. From beneath the pavement the pipes and wires must be separately led into the basements of each building and up through successive stories to the apartments above. Within the building, separate vertical car lines called elevators, must be built and city transportation becomes a matter of three dimensions with train service running in from principal outlying points, cross-town trolley lines and vertical elevators, all separate schemes of transportation requiring changes and delays, endless duplication, colossal expense and criminal waste.

Now rails, pipes and wires can be most economically laid in continuous straight lines. In the case of railroads, the greater the speed without stops the more the necessity for straight lines. A car running at a speed of forty miles per hour has sixteen times the force for derailment as a car at ten miles, and there is a like increase in the cost in power and time to stop the car. Moreover, to be efficient the railway should be where nothing will obstruct the passage of trains. Pipes must be kept from freezing, live wires from giving shocks and yet all must be available for new installation and repairs. None of these needs are filled by present city conditions; all can be fulfilled if the city is planned to fit the rail, pipe and wire civilization of to-day instead of the pedestrian and equestrian civilization of the past.

Building in One Dimension.

The Roadtown is a scheme to organize production, transportation and consumption into one systematic plan. In an age of pipes and wires, and high speed railways such a plan necessitates the building in one dimension instead of three—the line distribution of population instead of the pyramid style of construction. The rail-pipe-and-wire civilization and the increase in the speed of transportation is certain to result in the line distribution of population because of the almost unbelievable economy in construction, in operation and in time. The people will return to Mother Earth because it is in every way desirable for them to do so and not because some merchant prince, railroad king or social worker says they ought to go.

In modern life an office building, store or apartment house is considered especially fortunate if it has a rapid transit station near or better still within the building. All the inhabitants of the Roadtown will live upon the main line and be near the station. They will live there because the utilities of civilization can be provided there more economically than elsewhere. But the line distribution has yet another significance of as great importance as the more safe and economical distribution of people, parcels, fluids and electricity.

The development of cities was originally brought about by the desire of men to get close together for industrial needs and social fellowship. This same want for ready communication and distribution of men and things I have shown can now be most completely fulfilled by the city which will be strung out in a line. In other words, the very laws which built the congested cities will, with the construction of the first section of the first Roadtown, surely mark the beginning of their gradual dissemination. Such a tendency can already be seen at work, but its development has not progressed far because of the isolation of the functions of house construction and horizontal transportation devices.

As soon as horizontal transportation is put in the house, the skyscraper on its side, and is pointed towards the endless country instead of up against the force of gravity, and the wonderful transportation devices now available are installed, you will see the cities spread out in lines amidst the fields and farms, as if by magic. Indeed it will be the magic of economy, the natural force to which all of humanity always promptly responds.
