In 1904, Sumner was ageing but not ready to retire fully, so a new suffragan See of Dorking was erected and Cecil Boutflower was appointed Bishop of Dorking early the next year.[7] When Boutflower departed for Japan, Sumner resigned the See in early 1909 (before John Randolph's consecration on 21 February 1909)[8] and Randolph was appointed Bishop of Guildford, succeeding Boutflower in duties and Sumner in the See.[9]
