The Outcomes of the Life of a Geologist: An Autobiography

The Outcomes of the Life of a GeologistBy T. Nelson Dale (1846-1937)

With a donkey, two paniers, a magnifying glass and a stone hammer, T. Nelson Dale set off to record the Geological structure of the Eastern Seaboard. Such an enormous task and primitive means were the norm for early twentieth century geologists, but Dale in particular. He returned months later with an extensive analysis of the region, still used today. This is an autobiography, and Dale reveals himself on the one hand a fearless explorer and passionate researcher. On the other, one with petty academic rivalries and, frankly, some very odd observations on life. His eccentricity is refreshingly transparent, however. He contributed significantly to the slate industry of Pennsylvania and allows the reader a look into the exceptional life of an unusual geologist.

New Lives in the Valley (1850-1920)

New Lives in the ValleyBy Gwilym R. Roberts

Gwilym Roberts led a very successful academic life as Dean of Arts and Humanities at the University of Farmington, Maine. Both his father and two Welsh immigrant grandfathers were slate workers from Brownville, Maine, and this heritage became the subject of his book, New Lives in the Valley. The Valley is, of course, the Slate Valley, running for twenty miles along the Vermont/New York state line. The subject of his book, the steady flow of immigrants that discovered and supplied labor for the slate quarries of the Valley. It is the story of America, demonstrated clearly in the microcosm of the quarrying industry. Slate Barons rise and fall; angry workers strike; competing ethnic groups clash and finally assimilate into the burgeoning American culture. Beyond the quarries, Roberts includes the social and political development of the region. A sound historical account, but written to enjoy.

The River and the Ridge, 300 years of local history

The river and the ridgeRoger B. Wilson, Don C. Robinson, James L. Morris and David B. Glen

The authors are self-described “locals” of Delta, Pennsylvania. They love where they live and the stories that abound in one of the greatest slate regions of the United States. The Susquehanna River—its history of trade and transportation—and the famed Slate Ridge that produced the world-class Peach Bottom slate, are the main actors in this photo-filled account of their local history. A brilliant chapter on the region’s geology makes it clear (finally) how slate is formed, while chapters on Farming, the Railway, Roads, Business and Church bring their history to life. The authors worked hard and selflessly to produce an intriguing account of their community, for their community. All proceeds go to the Old Line Museum.
