[ [185] Thomas Day, the eccentric but kindly author of ‘Sandford and Merton,’ lent Boulton 3000l. at 4 per cent. When Boulton came to pay a higher rate of interest on other loans, he wrote Day proposing to pay him the same rate; but Day refused to accept the advance, as he could not make more of his money elsewhere. Day, however, offered him some good advice. “Give me leave,” said he, “with the real interest of a sincere friend, to express my wishes that now at last when a fortune is within your power, you will contract that wide sphere of business in which your ingenuity has so long kept you engaged, and which has prevented you hitherto, if I may believe the words of one of your sincerest friends, the late Dr. Small, from acquiring that independence which you ought to have had long ago. I should think that now, like a good Christian, thoroughly convinced of the inutility of other works, you ought to attach yourself to the one thing needful, and determine to be saved ‘even as by fire.’ You are now, dear Sir, not of an age to sport any longer with fortune. Forgive the freedom of these sentiments, and believe me, with the greatest sincerity and regard, Yours, &c.,
“Thomas Day.”
[ [186] Watt to Boulton, 20th January, 1779.
[ [187] Some of the specimens in water colour are to be seen at the Museum of Patents, South Kensington. When the paper is moistened with the finger, the colour easily rubs off. The whole subject of these pictures has recently been thoroughly sifted by M. P. W. Boulton, Esq., in his ‘Remarks on some Evidence recently communicated to the Photographic Society’ (Bradbury and Evans, 1864), apropos of the Papers of Mr. W. P. Smith on the same subject, in which it was surmised that they were the result of some photographic process. Mr. Boulton clearly shows, from the original correspondence, that the process was mechanical colour-printing. He also adds,—“From the brief statements which I remember to have heard from my father concerning the polygraphic process, my impression of it was that it copied colour mechanically, not merely chiaro-scuro. And I agree with the opinion which has been expressed to other persons, that in the coloured specimens in the Museum, there are indications that the colour was laid on mechanically,—not by hand or brush.” As the process of “dead-colouring” the pictures is occasionally referred to, it is probable that the pictures passed through more stages than one, as in the case of modern colour-printing. In one of Eginton’s letters, three plates were spoken of as necessary for taking impressions of one of the pictures.

[ [190] On the 18th May, 1780, Watt wrote Boulton, then in London, as follows:—“I am sorry, my dear Sir, to prove in any shape refractory to what you desire, but my quiet, my peace of mind, perhaps my very existence, depend on what I have told you. I am unhappy in not having any person I can advise with on this subject; and my own knowledge of it is insufficient. Therefore, if I appear too rigid, do not blame me, but my ignorance and timidity.” And again, on the 19th, on returning the draft mortgage, he wrote:—“If my executing this deed cannot be dispensed with, I will do it, but will not execute any personal bond for the money. I would rather assign you all Cornwall on proper conditions than execute this.”

[ [192] Boulton, at Plengwarry, to Watt, at Birmingham, 14th September, 1780. This day was Boulton’s birthday, and alluding to the circumstance he wrote,—“As sure as there are 1728 inches in a cubic foot, so sure was I born in that year; and as sure as there are 52 weeks in the year and 52 cards in the pack, so surely am I 52 years old this very day. May you and Mrs. Watt live very long and be very happy.”
