"I'll send the kid down with the thing and a billy of milk." - "The Woman at the Store", from "Selected Short Stories" by Katherine Mansfield (first published in 1912)
"'I’m going to knock off work and try to make some money,' said Mitchell, as he jerked the tea-leaves out of his pannikin and reached for the billy..."
"Mitchell and I turned off the track at the rabbit-proof fence and made for the tank in the mulga. We boiled the billy and had some salt mutton and damper."
"Then he lifted his swag quietly from the end of the floor, shouldered it, took up his water-bag and billy, and sneaked over the road, away from the place, like a thief."
