“As soon as we got to London, I went according to my direction. The young gentleman had been more punctual in writing home than young gentlemen sometimes are. I was appointed to come with my models the next evening, when a number of young people were collected, beside the children of the family. The young spectators gathered round me at one end of a large saloon, asking me innumerable questions after the exhibition was over; whilst the master of the house, who was an East India director, was walking up and down the room, conversing with a gentleman in an officer’s uniform. They were, as I afterwards understood, talking about the casting of some guns at Woolwich for the East India Company. ‘Charles,’ said the director, coming to the place where we were standing, and tapping one of his sons on the shoulder, ‘do you recollect what your brother told us about the proportion of tin which is used in casting brass cannon at Woolwich?’ The young gentleman answered that he could not recollect, but referred his father to me; adding, that his brother told him I was the person from whom he had the information. My memory served me exactly; and I had reason to rejoice that I had not neglected the opportunity of gaining this knowledge, during our short stay at Woolwich. The East India director, pleased with my answering his first question accurately, condescended, in compliance with his children’s entreaties, to examine my models, and questioned me upon a variety of subjects: at length he observed to the gentleman with whom he had been conversing, that I explained myself well, that I knew all I did know accurately, and that I had the art of captivating the attention of young people. ‘I do think,’ concluded he, ‘that he would answer Dr. Bell’s description better than any person I have seen.’ He then inquired particularly into my history and connexions, all of which I told him exactly. He took down the direction to Mr. Y----, and my good master (as I shall always call Mr. R----), and to several other gentlemen, at whose houses I had been during the last three or four years, telling me that he would write to them about me; and that if he found my accounts of myself were as exact as my knowledge upon other subjects, he thought he could place me in a very eligible situation. The answers to these letters were all perfectly satisfactory: he gave me the letter from Mr. R----, saying ‘you had better keep this letter, and take care of it; for it will be a recommendation to you in any part of the world where courage and fidelity are held in esteem.’ Upon looking into this letter, I found that my good master had related, in the handsomest manner, the whole of my conduct about the discovery of the vein in his mine.
