In 1920 the Trust lost the last of its three founders, Rawnsley. The Trust's 5000 acres of land in the Lake District were augmented by gifts in his memory, including part of the Great Wood on Derwentwater. In 1923 literary critic John Bailey took over as chairman of the Trust. Under his chairmanship the Trust saw an increase in funds, membership and properties. The 1920s saw the acquisition of more archaeological sites, including Cissbury Ring in West Sussex, and early buildings, including two medieval castles (Bodiam Castle in East Sussex and Tattershall Castle, Lincolnshire) bequeathed to the Trust by Lord Curzon. In 1925 the Trust launched a national appeal to buy the Ashridge Estate in Hertfordshire, successfully raising a record £80,000. When Bailey died in 1931 "The Times" paid tribute to him: "The strong position which the National Trust now occupies is largely due to him, and it will perhaps never be known how many generous gifts of rural beauty and historic interest the nation owes, directly or indirectly, to his persuasive enthusiasm."
