This book is an interesting and informative work. It gives a brief overview of what the iron industry was like during the end of the 18th and majority of the 19th centuries. It discusses methods that were used in smelting the iron, and the importance that iron had in the daily lives of those who lived in that era. It will also give you a glimpse of what life was like during that period of time. It will increase your knowledge of a former day, and give you an appreciation of what those people went through so that things can be where they are today. This book is well written, and easy reading. I would recommend it to anyone who would like to learn more about the importance of iron and life in the 19th century.
