“The Coalbrookdale engine is, I believe, the first locomotive engine on record, intended to be used _on a railroad_. The boiler of it is now to be seen in use as a water tank, at the Lloyds’ Crawstone Pit, and the fire-tube and a few other portions of it are now in the yard at the Madeley Wood Works. I never heard how it came to be disused and broken up.” Shortly before William Reynolds’s decease, he had had a large pleasure boat built, which was intended to be propelled by steam, and the cylinders of the engines intended for it, beautifully executed by the late James Glazebrook of Ironbridge, are now at the Madeley Wood Offices, but the engines were not finished at his (W. Reynolds’s) death, in 1804, and I never saw any drawing or model of them. The boat lay within my recollection, moored in the river Severn, just above Mr. Brodie’s Boring Mill, at the Calcutts, in a state of much disrepair, and I believe, ultimately fell to pieces or was carried away by a flood. William Reynolds had a very complete private Laboratory at his residence, at Bank House, which was lighted with gas. William Murdock had, however, as early as 1794, applied gas to the lighting of his own house, in Cornwall, and in 1798, a portion of the Soho Works were lit with gas of his making.—In 1803, the whole of the Works were thus lighted, and from that time its use gradually extended. Mr. Miller, of Darswinton, had a steam pleasure boat at work in 1788, and in 1801, the “Charlotte Dundas” steam boat was built at Glasgow by Symmington, and this is the first authentic case of steam-boat navigation on record. THE CLAY INDUSTRIES OF THE DISTRICT. The very excellent coal-measure clays found on both banks of the Severn, and turned to such good account by the Coalbrookdale Co., by Mr. Legge at the Woodlands, by neighbours too on the opposite bank of the Severn, as well as the celebrity attained by the Coalport works, renders it necessary that we should take a somewhat comprehensive view of the subject. Bricks and tiles and pottery of various kinds appear to have been made from a very early period, but the manufacture of Salopian porcelain dates from the latter end of the last century. The sites of the old pot works were at the outcrops of the coal-measure clays; and it was the advantages the fire-clays and accompanying coals afforded which led to the manufacture of porcelain. The former were situate at Benthall and Jackfield, where advantage is still taken of them, flourishing works being still carried on in places where these very excellent materials are readily procurable; and before noticing the introduction and very successful manufacture of the former at Caughley and Coalport, it may be desirable to devote a few pages to a description of the old pot-works, at Haybrook, the Pitchyard, and at Jackfield.
