(p. 180) Anyone who has ever supervised a talented subordinate with a tendency to set his own priorities will find Watt’s letters familiar: “I wish William could be brought to do as we do, to mind the business in hand, and let such as Symington [William Symington, the builder of the Charlotte Dundas, one of the world’s first steam-engine boats] and Sadler [James Sadler, balloonist and inventor of a table steam engine] throw away their time and money, hunting shadows.”
