But before the experiment with the wheel-engine could be tried at Soho, the financial ruin of Dr. Roebuck brought matters to a crisis. He was now in the hands of his creditors, who found his affairs in inextricable confusion. He owed some 1200_l._ to Boulton, who, rather than claim against the estate, offered to take Roebuck’s two-thirds share in the engine patent in lieu of the debt. The creditors did not value the engine as worth one farthing, and were but too glad to agree to the proposal. As Watt himself said, it was only “paying one bad debt with another.” Boulton wrote to Watt requesting him to act as his attorney in the matter. He confessed that he was by no means sanguine as to the success of the engine, but, being an assayer, he was willing “to assay it and try how much gold it contains.” “The thing,” he added, “is now a shadow; ’tis merely ideal, and will cost time and money to realise it. We have made no experiment yet that answers my purpose, and the times are so horrible throughout the mercantile part of Europe, that I have not had my thoughts sufficiently disengaged to think of new schemes.”[130] [130] Boulton to Watt, 29th March, 1773. Boulton MSS. So soon as the arrangement for the transfer of Roebuck’s share to Boulton was concluded, Watt ordered the engine in the outhouse at Kinneil to be taken to pieces, packed up, and sent to Birmingham.[131] Small again pressed him to come and superintend the work in person. But before he could leave Scotland it was necessary that he should complete the survey of the Caledonian Canal, which was still unfinished. This done, he promised at once to set out for Soho. In any case, he had made up his mind to leave his own country, of which he declared himself “heart-sick.”[132] He hated its harsh climate, so trying to his fragile constitution. Moreover, he disliked the people he had to deal with. He was also badly paid for his work, a whole year’s surveying having brought him in only about 200_l._ Out of this he had paid some portion to Dr. Roebuck to help him in his necessity, “so that,” he said, “I can barely support myself and keep untouched the small sum I have allotted for my visit to you.”[133] Watt’s intention was either to try to find employment as a surveyor or engineer in England, or obtain a situation of some kind abroad. He was, however, naturally desirous of ascertaining whether it was yet possible to do anything with the materials which now lay at Soho; and with the object of visiting his friends there and superintending the erection of the trial-engine, he at length made his final arrangements to leave Glasgow. We find him arrived in Birmingham in May, 1774, where he at once entered on a new and important phase of his professional career.
