When man made use of natural or unimproved means of transportation only, his progress socially and culturally was slow; when he developed mechanical means of moving from place to place, it was accelerated. The modern highway and its complement, the auto mobile, together represent the broadest means oi land transportation yet attained. It is impossible to separate these two factors; the automobile is worthless without the improved road and the road is of limited value without the automobile. Together, they have lengthened the span of average life appreciably. They have reduced the amount of time we must spend in travel. They have emancipated man from provincialism. They have given him quick and easy means of direct contact with distant communities. They have opened up to him, for business or enjoy ment, thousands of square miles of country, educated him to the healthfulness of outdoor travel and recrea tion, enabled him to live amid more healthful sur roundings at no sacrifice of convenience.
