An example of the elder Richard's inventive skill as an engineer was given when he repaired, or rather, almost reconstructed, about 1775, Newcomen's old Carloose, or Bullan Garden engine; especially by adding thereto a strong top of new form to the boiler, a drawing of which is given in the Appendix to Price's 'Mineralogia Cornubiensis,' 1778. The old boiler-tops were scarcely more than kettle-lids, and were actually weighted down in order to keep them in their places; indeed, there is a tradition that the first Cornish boilers were nothing more than stone fire-places! In effecting this improvement Richard Trevithick, senior, was assisted by one John Harvey,[143] the founder of the celebrated firm of Harvey and Co., of Hagle Foundry, of whom we shall hear more by-and-by. But about 1777 Watt, the celebrated 'low-pressure' engineer, appeared on the scene with his improvements in the steam-engine; travelling into Cornwall for the purpose of obtaining orders, erecting his first engine at Wheal Busy, and exciting the most angry jealousy on the part of all the local mine-managers and engineers--and notably our Richard: who, however, had the magnanimity and good sense at length to acknowledge and to adopt many of his illustrious rival's improvements. The old man, who was a pious Methodist, a 'class-leader,' and an intimate friend of John Wesley, died when sixty-two years old at Penponds, near Camborne, on the 1st August, 1797, and, I believe, was buried on the summit of Carn Brea, but no monumental stone marks the spot. The whole of his life was spent amongst mines and steam-engines, an industry which was deeply depressed at the time of his death; and Richard, the younger (who had married Jane, John Harvey's tall and buxom daughter, shortly prior to his father's decease), may be said to have succeeded to a 'heritage of woe: 'not one in ten of the steam-engines which his father had contributed so much towards putting into operation being at that time at work, and our hero had almost to begin the work anew.
