"I observe you have thought proper to insert the last number of the Philosophical Magazine your opinion that my attempts at the safety tubes and apertures were borrowed from what I have heard of Sir Humphrey Davy's researches. The principles upon which a safety lamp might be constructed I stated to several persons long before Sir Humphrey Davy came into this part of the country. The plan of such a lamp was seen by several and the lamp itself was in the hands of the manufacturers during the time he was here."

“Left home in company with John Dixon to attend the internment of George Stephenson at Chesterfield. I fear he died an unbeliever. When I reflect on my first acquaintance with him and the resulting consequences my mind seems lost in doubt as to the beneficial results — that humanity has been benefited in the diminished use of horses and by the lessened cruelty to them, that much ease, safety, speed, and lessened expense in travelling is obtained, but as to the results and effects of all that railways had led my dear family into, being in any sense beneficial is uncertain.”

“It will hereafter be scarcely believed that an invention so eminently scientific, and which could never have been derived but from the sterling treasury of science, should have been claimed on behalf of an engine-wright of Killingworth, of the name of Stephenson — a person not even possessing a knowledge of the elements of chemistry.”

“George Stephenson told me as a young man that railways will supersede almost all other methods of conveyance in this country — when mail-coaches will go by railway, and railroads will become the great highway for the king and all his subjects. I know there are great and almost insurmountable difficulties to be encountered; but what I have said will come to pass as sure as you live.”

“I am glad to learn that the Parliament Bill has been passed for the Darlington Railway. I am much obliged by the favourable sentiments you express towards me, and shall be happy if I can be of service in carrying into execution your plans.”

“I was threatened to be ducked in the pond if I proceeded, and of course we had a great deal of the survey to take by stealth at the time when the persons were at dinner; we would not get it by night, for we were watched day and night and guns were discharged over the ground belonging to Captain Bradshaw to prevent us. I can state further, I was twice turned off the ground myself by his men; and they said if I did not go instantly they would carry me off to Worsley.”

“To tell you the truth although it would put £500 in my pockets to specify my own patent rails, I cannot do so after the experience I have had.”
