Loudon’s 1825 Encyclopedia of Agriculture 

‘Pleased with the success of his first encyclopedia, Mr Loudon at once set to work on his second: the Encyclopedia of Agriculture. His plan, as with its predecessor, was to set the subject in a broad historical and geographical context. His travel notebooks were useful but it was a substantial task and the additional three years with little or no sleep further damaged his health.’ This is a quote from The Claudians: gardens, landscapes, reason and faith: John Claudius Loudon and Claudius Buchanan, Tom Turner (Kindle, 2024).
