The march of death and time have removed all the men who were engaged in assisting James Watt and Matthew Boulton in their great works.  The numerous mechanical trades in coining, plating, and other Birmingham manufactures, in addition to the construction of steam engines, which first turned the waste of Soho into the largest workshop in Europe, have passed into other hands, and been transplanted.  The manufactory of steam engines, removed to another site, still exists under the name of the old firm; but within a very recent period the pleasure grounds in which James Watt often walked, in earnest converse with the partner to whose energetic and appreciative mind he owed so much, have been invaded by the advances of the neighbouring town, and sliced and divided into building lots.  Aston Hall and Park must soon suffer the same fate.

Very soon there will be no vestiges of the homes of these great men, but they need no monuments, no shrines for the reverence of admiring pilgrims.  Every manufactory in the town of Birmingham is a monument of the genius which first fully expanded within the precincts of Soho.  Thousands on thousands find bread from inventions there first perfected or suggested.

When Watt explained to Smeaton, the architect of Eddystone Lighthouse and the greatest engineer of the day, the plan of his steam engine, he doubted whether mechanics could be found capable of executing the different parts with sufficient precision; and, in fact, in 1769, when Watt produced, under the patronage of Dr. Roebuck, his third model, with a cylinder of block tin eighteen inches in diameter, there were only one or two men capable of giving the requisite truth of workmanship to air-pump cylinders of two inches in diameter.  At the present day, as before observed in reference to Wolverton, there are thousands of skilled workmen employed at weekly wages, to whom the most difficult problems of Watt’s early experiments are familiar handiwork.

At Handsworth, too, working for a long life in the Soho manufactories as the servant, confidential assistant, and friend, lived another remarkable man, William Murdoch, the inventor of illumination by gas, and the author of the first locomotive steam engine, and of several important contributions to practical science, to which justice has scarcely been done.

William Murdoch employed coal gas so early as 1792, for the purpose of lighting his house and offices at Redruth, in Cornwall, when he was superintending the pumping engines erected there by Messrs. Boulton and Watt; for it was he who erected for them in that district the first Cornish pumping engine, with separate condenser.  He had at that time in regular use a portable gas lantern, formed by filling a bladder with gas, and fixing to it a jet, which was attached to the bottom of a glass lantern, which he used for the purpose of lighting himself home at night across the moors from the mining engines.
