The Map That Changed the World: A Tale of Rocks, Ruin and Redemption [Paperback]

Smith did not set out to produce a geological map of the British Isles, but to earn a living in the canal boom years before the advent of the railway era in Britain. The Somerset Coal Canal is another one of his legacies, and he also worked extensively throughput the Somerset coal field, to the South and West of Bath. His true insight may well have been at Mearns Pit, in High Littleton in this coal field. Like many noteworthy discoveries, Smith took many years to work out his ideas, to publish them (and even more to get credit for them).

Geology was at the forefront of science in late 18th century. There were lots of gentleman-scientists, who had rock collections. Slowly, Smith sought to bring order to the series of rocks that were visible in Britain, and he did this by comparing fossils from different locations. His insight was to realise that the order of rocks (in terms of strata) was passed on; if A is above rock B, and B is above rock C, then A must be above rock C. Seen from the 21st Century, that seemed obvious, but at the time it was a real struggle to breakout of the dogmas of the era. At the beginning of Smith's life, Bibles were still printed which declared the date of the earth's creation.

Simon Winchester has written a thoroughly absorbing account of Smith's life and work, and inhabited the pages with snippets of information about the life and times. It is well researched, and uses letters and diary entries of Smith and his contemporaries that survive. Smith cuts a figure of tragedy at times, with disappointment seeming to follow him around. His ideas were all but stolen, he spent some weeks in jail for debt in the summer of 1819, and he missed out on several chances to work abroad, staying for hollow promises of work in London.

I enjoyed the line-drawings of fossils that headed each chapter, and the glossary of geological terms was a useful addition. I also never realised that the house that has an inscribed tablet championing Smith (a little over 4 miles from where I live, myself at the Northern limit of the Somerset coal field) is the wrong house! A very good read, and one of the growing series of history of science books published in the last few years. What Smith's contemporaries failed to do in the early years of the nineteenth century, Simon Winchester has done; hailed a truly remarkable man who travelled the length and breadth of Britain to produce a lasting product; a map. Fortunately Smith was recognised in his lifetime (eventually) and honoured accordingly. Now we can do the same.

If ever you can judge a book by its cover, this is it. The copper embossed dust cover hints at the treasure buried within. From its binding, to the choice of paper to the fine etched illustrations, this is a very classy book.

Winchester takes us aboard one of the most effective literary time machines ever to land on a bookshelf. His writing sweeps us back 200 years to an England that was going through an industrial, scientific and social revolution.

Coal was king. Coal was the fuel for steam power. In turn, steam drove Britannia's economic engines.

William Smith was skilled as a geologist, engineer and cartographer. His observations and maps allowed landowners to discover and exploit the coal resources that lay beneath their land.

Smith's science went well beyond that of defining the strata containing the valuable coal. He devised the concept of stratigraphy, which would allow the relative age and spatial distribution of sedimentary rocks to be quantified.

It was this work, that inspired Smith's fellow geologist Charles Lyell to write "The Principles of Geology". When Charles Darwin went on his voyage of discovery it was the geological insights of Lyell and Smith that allowed Darwin to conceive of the vastness of the geological time scale. It is Winchester's thesis that Smith's map changed the world because of this direct influence on the most revolutionary scientific thinker of the 19th Century.

In the mid-1800s thanks to Darwin, geology was considered to be "The Father of Sciences".

The beauty of Winchester's writing is his evocation of the world in which Smith lived 200 years ago. His description of the English landscapes brings home to us the relationship between the underlying rocks and the aesthetics of the natural scenery we see around us.

Winchester's skills as a travel writer shine through. He surveys not only the landforms but also the social and political landscapes of this era. His clever use of the vocabulary of the era gives us a world inhabited by such people as beadles, tipstaffs and summoners. We travel in a conveyance called a myrmidon. His research is impeccable. We learn that there was an actual prison in London called "The Clink", and that the game of rackets or squash was invented in a debtors jail.

This book deserves its status as on of the great books of 2001. It should encourage readers to go back to Winchester's early work, particularly his travel writing. For readers who wish to learn more about Smith's influence on science should read Lyell's "Principles of Geology" which is still in print as a Classic. This is the book that Charles Darwin took on his voyage of discovery. "The Map That Changed the World" will take you on your very own voyage of discovery.

Graphics space aside, Winchester's descriptive abilities imparts this tale of a man's troubled life at the beginning of the 19th Century with sincerity. Keeping the great map that resulted from Smith's work before us throughout the book, Winchester brings all the threads together with graceful ease. Smith wandered the British countryside, collecting fossils, data, building a picture of what lay under the surface soil. He linked outcrops, canal cuts through hills, assembled samples and studied patterns. The result, as Winchester urges, "changed the world." The map led to a more vivid image of the Earth's formation and geologic activity, setting the stage for Lyell and Darwin. That rocks displayed patterns was the basis for the concept of change over time - the earth wasn't static. There was a discernible continuity over the millennia. Smith, of course, had no concept of the span of time involved, as Winchester reminds us, but without the schema Smith developed, we might yet still see the Earth as static.

Winchester avoids background description of Smith's era. This keeps this book within a reasonable size, but leaves Smith's working world a bit vague. It was, after all, the era of the Napoleonic wars. Britain was in social and political ferment. Natural science was burgeoning for numerous reasons, not the least of which was a strong rise in commercial and industrial endeavor. Smith's wife is characterized as a nymphomaniac, but the evidence for this is scanty. If her condition was publicly known it would have had strong impact on Smith's professional life. Was Smith's heavy debt load due as much to her as to his inadvisable property investments? Winchester was unable to unearth the fiscal details of Smith's life. It's enough that between fiscal and marital problems, Winchester shows how the morals of the era allowed Smith's work to be plagiarized without recourse. The combination of events finally led him into exile in Northern England. Although belated, Smith's story has a reasonably happy conclusion. Winchester traces the redemption of Smith's reputation and the honours bestowed near the end of his life.

The book is a stimulating read. Winchester isn't an arm-chair writer. He takes us along on his own journey across Britain, tracing Smith's path over the landscape. The book is, in effect, a second redemption of Smith, bringing him into the view of the modern world. Winchester shows us clearly how much work is involved in doing good science, especially with limited resources, erratic backing and an uncomprehending public. This book deserves the widest possible readership.
