Mr Fellowes, of Ludgate Street, who had previously been the publisher of some other volumes for me, had undertaken the publication of the first edition of the present work. A short time previous to its completion, I thought it right to call his attention to the chapter in which the book-trade is discussed; with the view both of making him acquainted with what I had stated, and also of availing myself of his knowledge in correcting any accidental error as to the facts. Mr Fellowes, 'differing from me entirely respecting the conclusions I had arrived at', then declined the publication of the volume. If I had then chosen to apply to some of those other booksellers, whose names appear in the Committee of 'The Trade', it is probable that they also would have declined the office of publishing for me; and, had my object been to make a case against the trade, such a course would have assisted me. But I had no such feeling; and having procured a complete copy of the whole work, I called with it on Mr Knight, of Pall Mall East, whom until that day I had never seen, and with whom I had never previously had the slightest communication. I left the book in Mr Knight's hands, with a request that, when he had read it, I might be informed whether he would undertake the publication of it; and this he consented to do. Mr Knight, therefore, is so far from being responsible for a single opinion in the present volume, that he saw it only, for a short time, a few days previous to its publication. It has been objected to me, that I have exposed too freely the secrets of trade. The only real secrets of trade are industry, integrity, and knowledge: to the possessors of these no exposure can be injurious; and they never fail to produce respect and wealth. The alterations in the present edition are so frequent, that I found it impossible to comprise them in a supplement. But the three new chapters, 'On money as a medium of exchange'; 'On a new system of manufacturing'; and 'On the effect of machinery in reducing the demand for labour'; will shortly be printed separately, for the use of the purchasers of the first edition.
