The sheep and cattle drank artesian water

  The sheep and cattle drank artesian water, not tapped from an easily accessible water table, but true artesian water brought from over three thousand feet below the surface. It gushed at boiling point from a pipe at what was called the borehead, and ran through tiny channels fringed with poisonously green grass to every paddock on the property. These channels were the bore drains, and the heavily sulphurated, mineral-laden water they contained was not fit for human consumption.
  At first the distances staggered them; Drogheda had two hundred and fifty thousand acres. Its longest boundary stretched for eighty miles. The homestead was forty miles and twenty-seven gates away from Gillanbone, the only settlement of any kind closer than a hundred and six miles. The narrow eastern boundary was formed by the Barwon River, which was what the locals called this northern course of the Darling River, a great muddy thousand-mile stream that finally joined the Murray River and surged out into the southern ocean fifteen hundred miles away in South Australia. Gillan Creek, which ran in the gully beside the head stockman's house, merged into the Barwon two miles beyond the Home Paddock.
  Paddy and the boys loved it. Sometimes they spent days on end in the saddle, miles away from the homestead, camping at night under a sky so vast and filled with stars it seemed they were a part of God. The grey-brown land swarmed with life. Kangaroos in flocks of thousands streamed leaping through the trees, taking fences in their stride, utterly lovely in their grace and freedom and numbers; emus built their nests 96 in the middle of the grassy plain and stalked like giants about their territorial boundaries, taking fright at anything strange and running fleeter than horses away from their dark-green, football-sized eggs; termites built rusty towers like miniature skyscrapers; huge ants with a savage bite poured in rivers down mounded holes in the ground.
  The bird life was so rich and varied there seemed no end to new kinds, and they lived not in ones and twos but in thousands upon thousands: tiny green-and-yellow parakeets Fee used to call lovebirds, but which the locals called budgerigars; scarlet-and-blue smallish parrots called rosellas; big pale-grey parrots with brilliant purplish-pink breasts, underwings and heads, called galahs; and the great pure white birds with cheeky yellow combs called sulphur-crested cockatoos. Exquisite tiny finches whirred and wheeled, so did sparrows and starlings, and the strong brown kingfishers called kookaburras laughed and chuckled gleefully or dived for snakes, their favorite food. They were wellnigh human, all these birds, and completely without fear, sitting in hundreds in the trees peering about with bright intelligent eyes, screaming, talking, laughing, imitating anything that produced a sound. Fearsome lizards five or six feet long pounded over the ground and leaped lithely for high tree branches, as at home off the earth as on it; they were goannas. And there were many other lizards, smaller but some no less frightening, adorned with horny triceratopean ruffs about their necks, or with swollen, bright-blue tongues. Of snakes the variety was almost endless, and the Clearys learned that the biggest and most dangerous looking were often the most benign, while a stumpy little creature a foot long might be a death adder; carpet snakes, copper snakes, tree snakes, red-bellied black snakes, brown snakes, lethal tiger snakes.
  And insects! Grasshoppers, locusts, crickets, bees, flies of all sizes and sorts, cicadas, gnats, dragonflies, giant moths and so many butterflies! The spiders were dreadful, huge hairy things with a leg span of inches, or deceptively small and deadly black-things lurking in the lavatory; some lived in vast wheeling webs slung between trees, some rocked inside dense gossamer cradles hooked among grass blades, others dived into little holes in the ground complete with lids which shut after them.
  Predators were there, too: wild pigs frightened of nothing, savage and flesh-eating, black hairy things the size of fully grown cows; dingoes, the wild native dogs which slunk close to the ground and blended into the grass; crows in hundreds carking desolately from the blasted white skeletons of dead trees; hawks and eagles, hovering motionless on the air currents. From some of these the sheep and cattle had to be protected, especially when they dropped their young. The kangaroos and rabbits ate the precious grass; the pigs and dingoes ate lambs, calves and sick animals; the crows pecked out eyes. The Clearys had to learn to shoot, then carried rifles as they rode, sometimes to put a suffering beast out of its misery, sometimes to fell a boar or a dingo.
