asked the Financial Secretary to the Treasury if he is aware that in September, 1921, 212 ex-service men qualified in the examination for the posts of officers of Customs and Excise; that 100 of these were immediately appointed and 112 placed on a reserve list; and that the men placed on the reserve list were officially informed that they would be eligible for vacancies as they occurred; and what steps have been taken to redeem the implied undertaking then given that vacancies as they occurred would be filled from the reserve list?
