A series of profile-like sketches of the people, departments, activities of an oil refinery, that combine to give the portrait of an industry that demands close cooperation between department and men. There is no plot, no central character, no single thread to bind the whole into one -- other than in the plant itself. Here are the pressure stills, the day shift, the old line bosses and workers, the newcomers -- efficiency experts, chemists, research men, and their dreams of futures; there are the occupational tragedies, labor troubles, reactions of men to women workers. There is the life outside the plant, the picture of the days of crude oil production, the clash as new ways come in, the close feeling of men for their jobs and their plant. First hand story of the drama of the works, with the human element well reported, and a somewhat technical approach to the plant itself. Less colored by the social aspects of the problem than, for example, the Halper books.
