the latter part of his career was spent in monmouthshire, glamorganshire, and montgomeryshire, for example on the monmouthshire & brecon canal in the early 1790s, often working with his two sons. he worked on many canal projects, including the neath and the aberdare, in many of which he was also a shareholder. until 1794, with his son and thomas sheasby, he was engineer and contractor on the glamorganshire canal, until they had a row with the company and were arrested for alleged overpayments. the matter was later resolved in their favour and they were exonerated.
