Lives of the Engineers

1. Stephenson floats a railway across Chat Moss

   Building the Liverpool and Manchester Railway in the late 1820s, George Stephenson had to cross Chat Moss, a bog of about twelve square miles that eminent engineers had declared impossible to cross. He laid the line on a floating raft of heather, brushwood hurdles and earth, and kept tipping spoil into the bog for weeks until the embankment finally held. The line opened in 1830, and Smiles presents the episode as proof that persistent empirical trial can defeat expert consensus.

2. Smeaton models Eddystone Lighthouse on oak

   After two earlier Eddystone lighthouses were destroyed, one by storm and one by fire, John Smeaton completed a stone tower in 1759. He modelled its profile on an oak trunk, with a broad base narrowing upward, and dovetailed its granite blocks into one another and into the rock. He also developed a hydraulic lime that set underwater.

3. Hand-trained practitioners outbuild formally schooled experts

   Smiles argues that the great engineers were mostly unschooled workmen: Brindley, a barely literate millwright; Telford, a shepherd's son and stonemason; George Stephenson, a colliery fireman who learned to read at eighteen. Their mastery came from years of handling materials and solving concrete problems, which gave them judgement that theory could not supply. Brindley, for example, worked out designs in his head, reportedly taking to bed to think a problem through, rather than on paper.

4. Roads and canals as engines of civilisation

   Smiles treats communications infrastructure as the precondition of moral and economic progress. Isolated districts stay poor, lawless and backward because goods, people and ideas cannot reach them. His evidence is Telford's Highland roads and bridges, which he credits with transforming the Scottish Highlands within a generation by opening markets, raising wages and dissolving clan isolation. On this view an engineer's works count as social reform, not just construction.
