Underground Treasures: How and Where to Find Them A Key for the Ready Determination of All the Useful Minerals Within the United States

"Underground Treasures: How and Where to Find Them" by James Orton is a handbook from the 1800s about finding and naming minerals. It teaches people how to find valuable minerals in the USA, even if they aren't scientists, and points out that many valuable minerals are missed or mistaken for less valuable ones. The book is meant to give easy-to-understand directions, like a "key," so that anyone can understand and discover the riches hidden in the dirt and rocks around them. This book pushes its readers to find mineral troves to open up riches hidden right under their feet.
