Read it through once

“The solitude seems intensified by the strange sounds of reptiles, birds, and insects, and by the absence of larger creatures; of which in the day-time, the only audible signs are the stampede of a herd of kangaroo, or the rustle of a wallabi, or a dingo stirring the grass as it creeps to its lair. But there are the whirring of locusts, the demoniac chuckle of the laughing jack-ass, the screeching of cockatoos and parrots, the hissing of the frilled lizard, and the buzzing of innumerable insects hidden under the dense undergrowth. And then at night, the melancholy wailing of the curlews, the dismal howling of dingoes, the discordant croaking of tree-frogs, might well shake the nerves of the solitary watcher.”
