Mines and Mills
Although Symington is best remembered for his contribution to steam powered vessels, he also built successful engines for mines and mills.
The first of these was built on a mine in Wanlockhead in 1790. This was followed by engines in Sanquhar, and then in London. In 1792, he built a large pumping engine that James Watt was also considered for. In the same year, he built an engine for the colliery of James Bruce. This marked a move to live near Falkirk and, later, a place as engine consultant for the Carron Company.
In 1793, he developed a crank drive with a crosshead above the cylinder, and built such an engine to wind coal from one of Bruce's pits. his engine proved very successful and about fifteen were built.
In all, there are firm references to thirty-two engines built by Symington up until 1808, and passing mention of several more.

Famous quotes containing the words mines and/or mills:
“Beautiful credit! The foundation of modern society. Who shall say that this is not the golden age of mutual trust, of unlimited reliance upon human promises? That is a peculiar condition of society which enables a whole nation to instantly recognize point and meaning in the familiar newspaper anecdote, which puts into the mouth of a distinguished speculator in lands and mines this remark:M”I wasn’t worth a cent two years ago, and now I owe two millions of dollars.””
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“They give us a pair of cloth shorts twice a year for all our clothing. When we work in the sugar mills and catch our finger in the millstone, they cut off our hand; when we try to run away, they cut off our leg: both things have happened to me. It is at this price that you eat sugar in Europe.”
—Voltaire [François Marie Arouet] (1694–1778)
