The tour series continues; this time two children are invited for a stroll through an oil field where they learn about methods of drilling oil and the role the geologist plays in the industry. The second half of the book is devoted to a careful inspection of the oil refinery itself where the functions of such machinery as the distillation unit and the ""cat cracker"" are explained.
