The example given should not be applied generally, but each case must be considered by itself. If there are collecting and marketing costs, they may be added to the terminal costs and the sum treated as a terminal charge.
Construction.
—It will hardly be necessary here to take up more individual cases. The almost universal use of trucks in the handling of materials of construction no doubt has affected the quantity and cost of construction, truly a productive process. Everyone is familiar with one or more of the many devices for loading and unloading, for in this class of haulage these things have reached a very high state of development.
Other Agencies.
—It is not the intention here to claim for the motor car entire credit for the manifold changes in marketing—buying and selling—which have occurred during the past two decades. Many other factors have entered into these changes and the corresponding advancement in the average standard of living. Transportation of all kinds, upon the highways, upon the railways, upon the waters, by telegraph, by telephone, by improvements in the postal service, and by the general increase in knowledge through the schools and printed literature, have all been instrumental in the development. But the automobile directly and indirectly has stimulated each of these activities and hence deserves credit with the rest.
