A globe does not show the core and deep layers under the surface. The core of the earth is like a huge heavy ball right at the heart of our big round globe. As we stand on the outside of the earth, the core is buried 1,800 m11es below the waves of the ocean and about 1,800 miles below every place on the land. The deepest parts of the seas dip down only about seven miles below the surface waves. A young traveler may have to strain his brain to think of a line 1,800 miles long. It took the brave ships of Columbus two whole months to sail this distance over the sea. An up to date car can go 60 miles an hour on a wide-open highway. If it travels without stopping, that car takes 30 hours to go 1,800 miles. Suppose we had a tunnel straight down to the center of our globe with elevators to speed up and down at a mil
