It is an odd coincidence that while writing of the events of fifty-eight years ago, pumping engines are being sent to those same mines with the steam-cylinder in twenty-two pieces, no piece to weigh more than 300 lbs.--a facility in mechanical arrangements not enjoyed by Trevithick--having Trevithick's high-pressure boilers, giving steam of 50 lbs. on the inch.[122] [Footnote 122: Made by Harvey and Co., Hayle, 1870.] [Rough draft.] "SIR. "CAMBORNE, _June 2nd, 1813_. "I drop you this note just to inform you that I have begun your job. Yesterday I engaged a great many smiths and boiler-builders, who set to work this morning. I have also engaged all the boiler-plates in the county, which will be sent to-day to the different workmen. The master-smiths that I have engaged are the best in the kingdom. I have obligated them to put the best quality of iron, and to be delivered at Falmouth within four months. I have been obliged to give them a greater price than I expected, otherwise they would not turn aside their usual business employment for a short job of four months. "Mr. Teague is with me, and one other, assisting about the drawings. If you call at Camborne about Friday, shall be able to show you the designs. The drawings for the castings will be sent to the iron-founders by the end of this week; and by the end of next week shall have the whole of the different tradesmen in full employ. If you wish to have a greater quantity of machinery ready by the end of September, there ought to be as little time as possible lost in giving your orders. I can get you double the quantity, provided you give the orders in time. "As soon as it is convenient to you to arrange the payments I would thank you to inform me, because we find in practice that the best way to make a labouring machine turn quickly on its centres, is to keep them well oiled. "R. T. "F. UVILLE, Esq., MR. HOOPER'S, _Falmouth_. "N.B.--If you intend to be at Camborne, please to drop me a note by post, and I will be at home." In all Trevithick's moves there was a scramble for money, in which he invariably came worst off. He could give a good hint that working centres would not turn well without the essential oil; but he failed to apply the principle to himself. Liberal words and golden prospects carried him off at once; and before Uville was strong enough to visit the Cornish mines and to fully explain what he wanted, the machinery was being made, though at that same time the thrashing and ploughing engines, and the locomotive and rock-boring engine, and the great fight with Watt at Dolcoath, were in progress.
