Letter from A V Hill to E B Bailey Thanks him for the report on geological work - suggests that he talk to Darwin or Ellis at the War Office about acting as geological adviser as 'every army ought to have [one]'. Notes that the Engineer in chief at the War Office is a 'firm believer in dowsing' - thinks he should put a question about dowsing being used for waterfinding to the Secretary of State for war, suggeting that geologists be consulted instead. 14 December 1942
