During World War I, Stable joined the Australian Army and became an official censor. In 1917, a
national referendum was held to allow conscription into military service; the
Australian Prime Minister Billy Hughes was strongly in favour of conscription. On 22 November 1917, the
Queensland Premier T. J. Ryan made a strong speech in the
Queensland Parliament against conscription. In the normal course of events, this speech would be reported in
Hansard. However, on 27 November 1917, Stable received a hand-written message from Billy Hughes ordering him, as censor, to take possession of all printed copies of Hansard under the censorship provisions of the
War Precautions Act. Stable went to the
Queensland Government Printing Office, but was prevented from entering by the
Queensland Police (who were apparently ordered to prevent his access by Premier Ryan). Stable then went to the
Victoria Barracks where he obtained a troop of Australian soldiers, and returned with them to the printing office. On this occasion, the police allowed him to enter. Then with the assistance of the Queensland Government Printer, all but 3 copies of the Hansard were destroyed. Only the copy retained by Stable himself is known to have survived, having been found amongst his garden tools after Stable and his wife had died; it is held by the
State Library of Queensland and is considered a treasure of the John Oxley Library collection. Another copy had been donated to the
National Library of Australia but it has since vanished. The fate of the third copy is unknown. ==Academic career==
