resulted in his withdrawing from co-operation with it. Both letters were 'very good and true as Gospel, but I fear I shall never be forgiven the publication of them.' Gurwood replied to the Duke that he feared to decide where the Duke had doubts but said that the letters would be a great loss to history and would entail the omission of others of a like tenor. He took the liberity to refer the letters back to the Duke for reconsideration; the letters appear in Volume 5. The Duke and Gurwood worked extremely well together, both of them demonstrating the efficiency and determination that the Duke famously described as his rule to 'do the business of the day in the day.' The volumes were produced at great speed and despite being very busy the Duke turned the material round quickly sometimes apologising for not being more prompt. Every entry had to be examined and approved by him both several times through to proof and print stage, with his being the final word. This involved Gurwood in much laborious copying out especially because Duke wanted to be assured at all times that the papers, whether with Gurwood or at Clowes the printers, were secure so that his emendations did not get into the public domain. As was customary at this time it was Gurwood who was solely financially responsible for all the expenses of publication. Clowes, the printers, kept accounts of their expenses which included advertising, stock control and distribution, and remitted any profits to Gurwood. In May 1838 the Duke sent Gurwood a draft for £500 to cover the cost of the free copies that Gurwood had given to his friends and relations. Gurwood declined the offer though he admitted that he had yet to gain by the publication. In December 1838 however he was able to tell the Duke that the expenses had been met from the sales. For the next three years Clowes remitted substantial sums to Gurwood. On the publication of Volume 12 in November 1838 Gurwood wrote to the Duke that when he began the work he had not been aware of its 'magnitude and importance' and he expressed his thanks for 'the confidence reposed in me by your Grace in permitting me to undertake the Compilation'. The Duke replied congratulating Gurwood on bringing 'before the Publick a Work which must be useful to Statesmen and
