Industrial Growth Stimulates: Economic Factors.—Economic factors are in general the most important in the development of a nation's transportation. Commercial and industrial growth stimulates invention and innovation in agriculture, mining, and manufacturing, which in turn tend to increase demand for transportation. Mechanization makes possible a greater division of labor, which increases productivity. Large-scale production becomes possible if extensive markets can be developed; this calls for the expansion of transportation facilities.
Lateral growth in trees frequently begins later than growth in height, but the period of lateral growth is longer. Rates of lateral growth likewise are low at the outset, increasing after a few weeks and then diminishing. In view of the long annual period of lateral growth in trees, deleterious environmental conditions may exercise a pronounced effect on growth. In the wood of trees of temperate regions, narrow and wide growth rings may be observed, marking years characterized by unfavorable and favorable conditions for growth.
But the industrial growth stimulates city was no less an image. The growth of the use of money from a medium of exchange in the early days of the development of international trade to its complete domination of the mind and spirit of western man by the middle of the 19th century was paralleled by a degeneration of cities and by a deliberate spoliation of the urban idea, which was quite on a par with the spoliation of natural resources and with the degradation of the peasant and the craftsman into the slum dweller. Steam, smoke, and slums were the gift of the industrial growth stimulates Revolution to the cities. |
