From a very early age he had shown great fondness for mechanical occupations. “His playthings,” it is said by one long acquainted with him, “were not the playthings of children, but the tools men work with; and he appeared to have greater entertainment in seeing the men in the neighbourhood work, and asking them questions, than in any thing else.” At the age of eighteen he was in the habit of forging iron and steel, and melting metal for his own use: and he possessed tools of every sort for working in wood, ivory, and metal. Some of these were of his own construction; and among them an engine for rose-turning, and a lathe by which he had cut a perpetual screw, a thing little known at that time. In the year 1750 he established himself in the Great Turnstile in Holborn, as a philosophical instrument-maker. While he followed this trade, he became known to the scientific circles by several ingenious inventions; among which were a new kind of magnetic compass, and a machine for measuring a ship’s way at sea. He was elected fellow of the Royal Society in 1753; and contributed several papers to the Philosophical Transactions, one of which, entitled ‘An Experimental Enquiry concerning the natural powers of water and wind to turn mills and other machines, depending on a circular motion,’ obtained the gold medal in 1759. In 1755 the Eddystone light-house was destroyed by fire. At this time Smeaton had never practised as an architect or engineer. But the proprietors, to use his own words, “considered that to reinstate it would require, not so much a person who had been merely bred, or who had rendered himself eminent in this or that given profession, but rather one who from natural genius had a turn for contrivance in the mechanical branches of science.” Thinking thus, they applied to the President of the Royal Society to recommend a fitting person, and he without hesitation named Smeaton. We shall speak hereafter of the difficulties which attended this work, and the method of its execution; the nature of it is familiar to every reader. Two light-houses had been destroyed within half a century: his own, after the lapse of seventy-three years, stands unimpaired;—a proud monument of the power of man to overcome the elements. This building was finished in 1759, and established his reputation as a civil engineer: but it was some time before he devoted his attention solely to practising in that capacity. In 1764 he was appointed one of the Receivers of the Greenwich Hospital Estates, and in the discharge of his duty, he suggested various improvements which were of material service to the property. He resigned that office about 1777, in consequence of the increase of his other business. In 1766 he was employed to furnish designs for new light-houses at the Spurn Head, at the mouth of the Humber, and after considerable delay, was appointed Surveyor of the Works in 1771. These were completed in April, 1777.
