Sitting astride the 14-foot Great Vein of bituminous coal, the communities of the Hocking Valley Coalfield were inextricably linked to the fortunes of a 50-year coal boom. Life in the Little Cities of Black Diamonds was not always easy or prosperous. Employment in the mines and clay plants rose and fell with economic conditions, and labor-management conflict led to strikes and violence. Even today, smoke from a mine fire, set deep underground during a strike in the 1880s, occasionally appears at the surface. Little Cities of Black Diamonds takes an intimate look at the miners, merchants, managers, and magnates who built the cities, villages, businesses, and homes of the Hocking Valley coal boom period. Since collapse of the coal industry around 1920, much has been lost, but the coal boom legacy lives on. In places such as Shawnee, New Straitsville, Eclipse, Glouster, and Haydenville, a small group of dedicated citizens works tirelessly to record, preserve, and celebrate the region's rich heritage.

Nestled in a hollow in the hills of Western Pennsylvania is the former coal-mining town of Marsteller, locally known as "Mosscreek". At its birth in the early 20th century, it was a company-owned town; and most of the miners had immigrated from Southern and Eastern Europe to fill the need of unskilled labor as the demand for coal increased. This book is a story about the colorful past of a town and its people; what life was like in the "Little City of Black Diamonds" which hummed with activity as it became a boom-town in the 1920's and 30's, and its decline after World War II as the demand for coal diminished.

Born in Roanoke County, Virginia, on the eve of the Emancipation Proclamation, Richard L. Davis was an early mine labor organizer in Rendville, Ohio. One year after the 1884 Great Hocking Valley Coal Strike, which lasted nine months, Davis wrote the first of many letters to the National Labor Tribune and the United Mine Workers Journal. One of two African Americans at the founding convention of United Mine Workers of America in 1890, he served as a member of the National Executive Board in 1886-97. Davis called upon white and black miners to unite against wage slavery. This biography provides a detailed portrait of one of America's more influential labor organizers.
