“Every day afforded me fresh occasion to form comparisons between the sultan and his son; and my attachment to my pupil every day increased. My pupil! It was with astonishment I sometimes reflected that a young prince was actually my pupil. Thus an obscure individual, in a country like England, where arts, sciences, and literature are open to all ranks, may obtain a degree of knowledge which an eastern despot, in all his pride, would gladly purchase with ingots of his purest gold.
“One evening, after the business of the day was over, Tippoo Sultan came into his son’s apartment, whilst I was explaining to the young prince the use of some of the mathematical instruments in my pocket-case. ‘We are well acquainted with these things,’ said the sultan in a haughty tone: ‘the government of Madras sent us such things as those, with others, which are now in the possession of some of my aruzbegs, who have doubtless explained them sufficiently to the prince my son.’ Prince Abdul Calie modestly replied, ‘that he had never before been made to understand them; for that the aruzbeg, who had formerly attempted to explain them, had not the art of making things so clear to him as I had done.’
“I felt a glow of pleasure at this compliment, and at the consciousness that I deserved it. How little did I imagine, when I used to sit up at nights studying my old master’s books, that one of them would be the means of procuring me such honour. {Footnote: Jervas here alludes to a book entitled, “A Description of Pocket and Magazine Cases of Drawing Instruments: in which is explained the use of each instrument, and particularly of the sector and plain scale, Gunter’s scale, &c. By J. Barrow, private teacher of mathematics.”}
“‘What is contained in that box?’ said the sultan, pointing to the box which held the model of the tin-mine. ‘I do not remember to have seen it opened in my presence.’
“I replied that it had not been opened, because I feared that it was not worthy to be shown to him. But he commanded that it should instantly be exhibited; and, to my great surprise, it seemed to delight him excessively: he examined every part, moved the wires of the puppets, and asked innumerable questions concerning our tin-mines. I was the more astonished at this, because I had imagined he would have considered every object of commerce as beneath the notice of a sultan. Nor could I guess why he should be peculiarly interested in this subject: but he soon explained this to me, by saying that he had, in his dominions, certain mines of tin, which he had a notion would, if properly managed, bring a considerable revenue to the royal treasury; but that at present, through negligence or fraud, these mines were rather burdensome than profitable.
“He inquired from me how my model came into my possession; and, when his interpreter told him that I made it myself, he caused the question and answer to be repeated twice, before he would believe that he understood me rightly. He next inquired whether I was acquainted with the art of mining; and how I came by my information: in short, he commanded me to relate my history. I replied that it was a long story, concerning only an obscure individual, and unworthy the attention of a great monarch: but he seemed this evening to have nothing to do but to gratify his curiosity, which my apology only served to increase. He again commanded me to relate my adventures, and I then told him the history of my early life. I was much flattered by the interest which the young prince took in my escape from the mine, and by the praises he bestowed on my fidelity to my master.
“The sultan, on the contrary, heard me at first with curiosity, but afterwards with an air of incredulity. Upon observing this, I produced the letter from my good master to the East India director, which gave a full account of the whole affair. I put this letter into the hands of the interpreter, and with some difficulty he translated it into the Carnatic Malabar, which was the language the sultan used in speaking to me.
“The letter, which had the counter-signatures of some of the East India Company’s servants resident at Madras, whose names were well known to Tippoo, failed not to make a great impression in favour of my integrity: of my knowledge he had before a high opinion. He stood musing for some time, with his eyes fixed upon the model of the tin-mine; and, after consulting with the young prince, as I guessed by their tones and looks, he bade his interpreter tell me that, if I would undertake to visit the tin-mines in his dominions, to instruct his miners how to work them, and to manage the ore according to the English fashion, I should receive from the royal treasury a reward more than proportioned to my services, and suitable to the generosity of a sultan.
“Some days were given me to consider of this proposal. Though tempted by the idea that I might realize, in a short time, a sum that would make me independent for the rest of my life, yet my suspicions of the capricious and tyrannical temper of Tippoo made me dread to have him for a master; and, above all, I resolved to do nothing without the express permission of Dr. Bell, to whom I immediately wrote. He seemed, by his answer, to think that such an opportunity of making my fortune was not to be neglected: my hopes, therefore, prevailed over my fears, and I accepted the proposal.
“The presents which he had made me, and the salary allowed me during six weeks that I had attended the young prince, amounted to a considerable sum; 500 star pagodas and 500 rupees: all which I left, together with my ring, in the care of a great Gentoo merchant of the name of Omychund, who had shown me many civilities. With proper guides, and full powers from the sultan, I proceeded on my journey, and devoted myself with the greatest ardour to my undertaking. A very laborious and difficult undertaking it proved: for in no country are prejudices in favour of their own customs more inveterate, amongst workmen of every description, than in India; and although I was empowered to inflict what punishment I thought proper on those who disobeyed, or even hesitated to fulfil my orders, yet, thank God! I could never bring myself to have a poor slave tortured, or put to death, because he roasted ore in a manner which I did not think so good as my own method; nor even because he was not so well convinced as I was of the advantages of our Cornwall smelting-furnace.
