In the capacity of Surveyor-General of His Majesty’s Works, he was receiving, in 1675, 13s. 2d. a day and “availes” of £80 per quarter, which meant another £320 a year, by way of retaining fee; and Papworth presumes, I think with reason, that he also received specific payment in respect of each service performed. By the year 1715, his salary and “riding charges” had dropped to £136 a year, but it is also to be remembered that all this time he had an official residence in Whitehall consisting of sixteen rooms and a cellar, which he occupied for about fifty years without cost to himself. In respect of Chelsea Hospital he received a fee of £1,000, but there are many examples of his refusing payment altogether. He insisted on doing all the work at Greenwich Hospital without payment, saying, “Let me have some share in an act of charity and mercy.” When he came to design the Library of Trinity at Cambridge, for which the Master had some difficulty in getting enough subscriptions, Wren’s contribution was the value of his own work, for which he made no charge; and, similarly, he received nothing in respect of his work at St. Clement Danes. These are acts of generosity of which we happen to have definite record, and I do not doubt that there were many other examples of the same sort not recorded, for Wren’s generosity was equalled only by his modesty. He was not above a trifling piece of nepotism; for his son Christopher became Deputy Clerk Engrosser in the Office of Works in 1694 and Clerk of Works in 1702, succeeding Dickenson. This appointment was confirmed by George I. in 1715. But when Sir Christopher fell from favour his son was also dismissed, and from the younger Christopher’s casual proceedings in the compilation of the material of _Parentalia_, I cannot believe that the State suffered greatly from his disappearance. During thirty-two years of Wren’s professional career, Nicholas Hawksmoor was his domestic clerk, which we may take to mean that he was in charge of Wren’s office and his right-hand man, both in designing and in the financial supervision of the works. It would appear that he performed a good many of the duties which now fall to the separate profession of quantity surveyor. I suspect that, for example, the payments to the various contractors for the City churches, and possibly also for St. Paul’s, were certified by Wren after the value of the work done had been examined by Hawksmoor. It seems certain that the very elaborate accounts of the City churches, with which I have dealt fully in _Archæologia_, were actually written out by Hawksmoor himself.
