Humans have been moving earth around for a long time—since well before the beginning of recorded history. The most basic early digging tool was the multi-purpose “digging stick.” The earliest shovels were probably fashioned from the shoulder blades (“scapula”) of large animals. They could be used for the removal of soil after it had been loosened by the digging stick. These days, shovels are generally used for light digging work, the heavier work being done by power equipment—initially steam shovels and later hydraulic equipment such as excavators, loaders, and bulldozers. Specialized underground work is accomplished by drills and tunnel boring machines.

About the Author

After being educated in economics at Yale University, David Ritchey served five years as an officer in the U.S. Navy, including a year in Vietnam. Back in civilian life, he initially became a businessman as he had been trained but, suffering from post-traumatic stress disorder, he dropped out, got a divorce, moved to a remote old stone farmhouse and took up fine art photography as his vocation, winning over 60 awards during the next fifteen years.

During that period, he became fascinated with the psychology and neurology of both creativity and metaphysics and returned to school to train as a psychotherapist. During his fifteen years of clinical practice specializing in hypnotherapy, he undertook a twelve-year project to research and write about such subjects and his first book, The H.I.S.S. of the A.S.P., was published in 2003. Writing proved to be every bit as rewarding as photography and became his primary vocation. Being an inveterate learner, he focused on non-fiction subjects, enjoying the research as much as the writing. His more than forty published works have won over 25 literary awards. His books can be found at www.davidritchey-author.com and online book stores.

He has two adult children, Harper and Mac, and one almost-adult grandchild, Brendan. He lives in historic Bucks County, Pennsylvania, and spends most of his time either writing or engaging in stimulating conversations over restaurant meals with close friends.
