What countries are most heavily shaded? What kind of countries are they? Compare the countries which have the second heaviest shading with those shaded most lightly. Compare this map with Figure 165, showing the distribution of manufacturing. What does this map indicate as to climate? In Asia, the only country that is highly developed industrially is Japan, where the climate, unlike that of China, has frequent changes from day to day and is relatively stimulating. There the people are unusually active in both mind and body. In the southern hemisphere, parts of Argentina, Chile, and southeastern Australia are favored both in climate and in race, but they are so new in commercial development and so far from markets and from a large labor supply that they are not yet important industrially. How power determines the location of industries. Those indus- iries that consume great quantities of fuel are strongly influenced by the location of coal mines or other supplies of fuel, such as natural gas and petroleum. Fuel. Pennsylvania well illustrates the effect of supplies of coal. Her preéminence in coal mining helps her to lead the states of the Union in the production of the following articles, which are among the heaviest consumers of fuel: coke; pig iron; pig steel; rolling mill products, such as rails and sheet iron; foundry and machine shop products, such as wrought iron and castings; railway cars, a large percentage of which are now made of steel ; glass, which requires high temperatures and much fuel to melt the sand; cement, a mixture of pulverized limestone and clay heated to a high temperature.
