Sir Christopher encouraged the famous engineer and inventor Richard Trevithick, and in the life of that worthy, by Francis Trevithick, are given some letters that passed between them; but Mr. F. Trevithick persistently calls Sir Christopher Sir Charles. Sir Kit was the first man to adopt a steam thrashing-machine in 1812, an invention of Trevithick; it was used for the first time at Trewithen in February in that year. A committee of experts was called in to witness its operations and report on them, and this is their report, dated February 12th, 1812:—
"Having been requested to witness and report on the effect of steam applied to work a mill for thrashing corn at Trewithen, we hereby testify that a fire was lighted under the boiler of the engine five minutes after eight o'clock, and at twenty-five minutes after nine o'clock the thrashing mill began to work, in which time one bushel of coal was consumed. That from the time the mill began to work to two minutes after two o'clock, being four hours and three-quarters, fifteen hundred sheaves of barley were thrashed clean, and one bushel of coal more was consumed. We think there was sufficient steam remaining in the boiler to have thrashed from fifty to one hundred sheaves more barley, and the water in the boiler was by no means exhausted. We had the satisfaction to observe that common labourers regulated the thrashing mill, and in a moment of time made it go faster, slower, or entirely cease working. We approve of the steadiness and the velocity with which the machine worked, and in every respect we prefer the power of steam, as here applied, to that of horse.

Sir Christopher entered into negotiation with Trevithick about constructing a breakwater to the harbour at S. Ives, at Pendinas Point. It was begun, but never completed, owing to the death of the baronet. But a good thing he did achieve, though done for a political purpose, by indirect bribery, was the establishment of a free school at S. Ives, in Shute Street; the charge of admission was one penny per week, and in it navigation was taught. It was opened on April 11th, 1822.
In the diary of Captain John Tregerthen Short of the events taking place at S. Ives between 1817 and 1838 we have: "1828, June 10th. At 10 a.m. Sir Christopher Hawkins, Bart., and Wellesley Long Pole, Esq., the former supporting the cause of the Right Hon. Sir Charles Arbuthnot, attended at the Town Hall, where Wellesley Long Pole, Esq., resigned the contest, and Sir Charles Arbuthnot was elected without opposition. Immediately afterwards Mr. Wellesley Pole made an active and successful canvass of the town for another election, and left S. Ives at 10 p.m., having given each voter 5s., and Sir Christopher Hawkins gave all his friends 5s."
"July 21st.—All Mr. Wellesley's voters had a public dinner; each received one guinea to defray the expense of the dinner, which came to 7s. 3d. per man." Oh, what a falling off is here! Only 5s. each voter, whereas elsewhere, at Grampound, Tregony, Penryn, and Mitchell, a free and independent elector would turn up his nose at £10. But Captain Short does not inform us what the douceurs had been that were paid previous to the election.
Sir Christopher Hawkins died of erysipelas at Trewithen on April 6th, 1829.
Captain Short enters on that day:—
"Sir Christopher Hawkins, Bart., departed this life this morning in the seventy-first year of his age. His death will be greatly felt and deplored by hundreds. His charitable contributions amongst the indigent will be found greatly wanting. A more generous and benevolent landlord could not be found. He was never known to distrain for rent. He established a Free School in S. Ives for the education of the poor, and gave the sum of £100 towards enlarging the Wesleyan Methodist Chapel in this town."
The Gentleman's Magazine for 1830 says that Sir Kit Hawkins's property at S. Ives was sold then, "which secures the purchaser a seat in Parliament, for the borough was lately sold by auction in London for the sum of £55,000. It is reported that the purchaser is the Marquess of Cleveland."
