All to often we loose gems from history and they
are never found. Whatever the rights and wrongs of
Google Books there are some true hidden gems that
are now accessible to the whole world.
The clips below are taken from a book published in 1844 about the construction of two railway tunnels south of London, England. The entire book is available to browse online and I can heartily recommend doing so. It is a true treasure trove of our engineering heritage and it is amazing how much has and has not changed in the 160 years since this book was published.
Practical Tunnelling Explaining in Detail, the Setting Out of the Works; Shaft-sinking, and Heading Driving; Ranging the Lines, and Levelling Under Ground; Sub-excavating, Timbering; and the Construction of the Brickwork of Tunnels: with the Amount of Labour Required For, and the Cost of the Various Portions of the Work: as Exemplified by the Particulars of Blechingley and Saltwood Tunnels By Frederick Walter Simms
