a conference on agricultural cooperation in the British Commonwealth in London, and in 1925 he visited South Africa to help the movement there. As late in 1930, he was consulting with the Prime Minister of Great Britain on agricultural policy. Personal life Horace was close to his nephews, Edward and Reginald Dunsany, helping manage their, and their father's, affairs. He also worked to reconcile the 17th Lord Dunsany and his wife over several years. He was very involved in the affairs of the 18th Lord Dunsany until some failures of investments in the 1920s, after which their contact was more occasional but continued to near the end. His dealings with Reginald were more limited in earlier years but he continued to visit him at Charborough and elsewhere, right up to the month of his death. He was also close friends with Elizabeth "Daisy" Burke Plunkett, Lady Fingall, the wife of his remote cousin. Horace became interested in aviation late in life and was still flying – presumably from Brooklands – at least as late as 1930. Last years During Plunkett's last years, Gerald Heard was his personal secretary. Naomi Mitchison, who admired Plunkett and was a friend of Heard, wrote: "H.P., as we all called him, was getting past his prime and often ill but struggling to go on with the work to which he was devoted. Gerald [Heard] who was shepherding him about fairly continually, apologized once for leaving a dinner party abruptly when H.P. was suddenly overwhelmed by exhaustion". Plunkett died at Weybridge on 26 March 1932 and was buried in St Mary's Churchyard in nearby Byfleet, where his gravestone survives.
