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 resourceful manual focused on mineralogy and prospecting, written in the late 19th century. The book addresses the practical identification and extraction of valuable minerals found in the United States, equipping readers with the knowledge to discern between useful minerals and their look-alikes, thereby highlighting the hidden wealth beneath the American landscape.

It outlines the fundamental premise that various minerals can be misrepresented, leading individuals to miss out on valuable resources. The author stresses the importance of practical knowledge for identifying useful minerals and sets the tone for the work's instructional nature with a promise of simplified guidelines and a metaphorical "key" that allows the layperson to unlock the monetary potential of the rocks and soils they encounter. This introductory chapter serves as a call to action for readers to actively engage in mineral exploration.
