After four month’s labour of this sort, during which seven out of the ten engines then in hand were finished and erected, and the others well advanced, Watt again set out for Cornwall, which he reached by the beginning of June, 1778. He took up his residence at Redruth, as being more convenient for Tingtang than Chacewater, hiring a house at Plengwarry, a hamlet on the outskirts of the town. Redruth is the capital of the mining districts of Camborne, Redruth, and Gwennap. It is an ancient town, consisting for the most part of a long street, which runs down one hill and up another. All round it the country seems to have been disembowelled; and heaps of scoriæ, “deads,” rubbish, and granite blocks cover the surface. The view from the lofty eminence of Carn Brea, a little to the south of Redruth, strikingly shows the scarified and apparently blasted character of the district, and affords a prospect the like of which is rarely to be seen. [Illustration: REDRUTH HIGH STREET. [By R. P. Leitch.]] On making inquiry as to the materials which had arrived during his absence, Watt was much mortified to find that the Soho workmen had made many mistakes. “Forbes’s eduction-pipe,” he wrote, “is a most vile job, and full of holes. The cylinder they have cast for Chacewater is still worse, for it will hardly do at all. The Soho people have sent here Chacewater eduction-pipe instead of Wheal Union; and the gudgeon pipe has not arrived with the nozzles. These repeated disappointments,” said he, “will undoubtedly ruin our credit in the country; and I cannot stay here to bear the shame of such failures of promise.”
