Find a soft place. Take a shovel and start to dig a hole. . .
So begins your trip through the center of the earth. You will have to dig about 8,000 miles to get to the other side of the world, and you'll need the latest equipment. As you dig you may find fossils, or diamonds and emeralds, or even strike oil. There will be problems, too—underground geysers and volcanoes and white-hot heat. But what a wild adventure! This book, while describing the layers of the earth, will delight any reader who has a sense of whimsy and a bent for adventure.
