Bulletin (Sydney) 20 July 12/3: On Wednesday ’Gor Save’ was the signal for the Gov. General’s contingent to set off. They took their time, too, in leaving.

On his arrival at the Schools’ display the children sang one verse of the Hanthem, and he doffed his hat and prepared to sit right royally, but 5000 juvenile voices got on to the second verse, and promptly brought him to attention.
