The following observations, recorded in Mr. Cunningham's Two Years in New South Wales, are as valuable as they are interesting; for hitherto we have known but little of the natural history of that country:—
Trees.—Trees here appear to follow the same laws as other vegetable substances, regarding the effects they produce upon the soil wherein they grow. It has long been remarked in America, that on the forests being cut down, young trees of a different species sprout up in place of the old ones; and here the same remark, in a great measure, holds good,—acacias very commonly making their appearance on land that has been once under cultivation, and afterwards permitted to relapse into a state of nature. From this circumstance it should seem, that trees, like other vegetables, extract a particular substance from the ground, which substance it is necessary should be restored before the same species of tree can be readily grown a second time,—a restoration to be effected, perhaps, by such chemical changes in the constituent particles of the soil as may arise from the cultivation of other species.
Fruits.—Of native fruits, we possess raspberries equal in flavour and not otherwise distinguishable from the English. They grow plentifully on the alluvial banks of Hunter's river, and supply a yearly Christmas feast to the birds. Oar native currants are strongly acidulous, like the cranberry, and make an excellent preserve when mixed with the raspberry. They grow on low shrubs not higher than the whortleberry bush. Our cherries are destitute both of pleasant taste and flavour, and have the stone adhering to their outside. Our native pears are tolerably tempting to the look, but defy both mastication and digestion, being the pendulous seed-pods of a tree here, and their outer husks of such a hard woody consistence, as to put the edge of even a well-tempered knife to proof of its qualities in slicing them down. The burwan is a nut much relished by our natives, who prepare it by roasting and immersion in a running stream, to free it from its poisonous qualities. The jibbong is another tasteless fruit, as well as the five-corners, much relished by children. The wild potato strongly resembles the species now in use in Europe, but the stem and leaf are essentially different. It grows on the loose flooded alluvial margins of the rivers, and at one period of the year composes the chief sustenance of the natives, having the watery look and taste of the yam. Of foreign fruits now climatized we possess a great variety. Here are oranges, lemons, citrons, nectarines, apricots, peaches, plums, cherries, figs, loquats, grenadillos, quinces, pears, apples, mulberries, pomegranates, grapes, olives, raspberries, strawberries, bananas, guavas, pineapples, and English and Cape gooseberries and currants. Of shell-fruits we have the almond, walnut, chestnut, and filbert; and of other garden fruits, strawberries, melons, peppers, &c.
Melons and pumpkins will absolutely overrun you, if you do not give them most bounteous scope, and you need want neither water nor musk-melons for six or eight months yearly on an average, if you duly time the sowings. Nothing can exceed their rich juiciness and flavour, and the rapidity of their growth is almost miraculous, when a few showers of rain temper the hot days. The pumpkin makes an excellent substitute for the apple in a pie, when soured and sweetened to a proper temper by lemons and sugar. The black children absolutely dance and scream when they see one, pumpkin and sugar being their delight. To the half of a shrivelled pumpkin hanging at the door of my tent on my first essay in settling, one of our sooty satyrs could do nothing for some minutes but fidget and skip; and with his eyes sparkling, and countenance beaming with ecstacy, exclaim, "Dam my eye, pambucan; dam my eye, pambucan!" such being the nearest point they can attain to the right pronunciation of their favourite fruit.
Birds.—We are not moved here with the deep mellow note of the blackbird, poured out from beneath some low stunted bush; nor thrilled with the wild warblings of the thrush, perched on the top of some tall sapling; nor charmed with the blithe carol of the lark as we proceed early afield; none of our birds at all rivalling these divine songsters in realising the poetical idea of the "music of the grove;" while "parrots' chattering" must supply the place of "nightingales' singing" in the future amorous lays of our sighing Celadons. We have our lark certainly, but both his appearance and note are a most wretched parody upon the bird our English poets have made so many fine similes about. He will mount from the ground, and rise fluttering upward in the same manner, and with a few of the starting notes of the English lark; but on reaching the height of thirty feet or so, down he drops suddenly and mutely, diving into concealment among the long grass, as if ashamed of his pitiful attempt. For the pert, frisky robin, pattering and pecking against the windows in the dull days of winter, we have the lively "superb warbler," with his blue shining plumage and his long tapering tail, picking up the crumbs at our doors; while the pretty little redbills, of the size and form of the goldfinch, constitute the sparrow of our clime, flying in flocks about our houses, and building their soft downy pigmy nests in the orange, peach, and lemon trees surrounding them. Nor are we without our rural noters of the time, to call us to our early task, and warn us of evening's close. The loud and discordant noise of the laughing jackass, (or settler's clock, as he is called,) as he takes up his roost on the withered bough of one of our tallest trees, acquaints us that the sun has just dipped behind the hills, and that it is time to trudge homewards; while the plaintive notes of the curlew, and the wild and dismal screechings of the flying squirrel, skimming from branch to branch, whisper us to retire to our bedchambers. In the morning, again, the dull monotonous double note of the whee-whee, (so named from the sound of its calls,) chiming in at as regular intervals as the tick of a clock, warns us to rub our eyes and con over the tasks of the impending day, as it is but half an hour to dawn; till again the loud laughter of the jackass summons us to turn out, and take a peep at the appearance of the morning, which just begins to glimmer beyond the dusky outline of the eastern hills.
Animals.—Our wild animals are numerous, but few of them carnivorous, and none of a size to endanger human life. The native dog is generally believed to be an importation, being deficient of the false uterus or pouch characterising all our other quadrupeds. He closely resembles the Chinese dog in form and appearance, being either of a reddish or dark colour, with shaggy hair, long bushy tail, prick ears, large head, and slightly tapering nose; in size he reminds one of a shepherd's dog, running with considerable speed, and snapping in attack or defence. He does not bark, but howls in melancholy sort, when prowling in quest of prey, and has a strong and peculiar odour, which makes European dogs shy at first of attacking him, doubtless intimidated too by his snapping mode of fighting; for it is observed of poodles, and all which snap, that few other dogs are fond of engaging them. He is most destructive on breaking in among a flock of sheep, as he bites a piece out of every one he seizes; not holding fast and worrying dead like the fox, but snapping at all he can overtake, till twenty or thirty may be killed by one dog, there being something so peculiarly venomous in their bite that few recover from it. Their cross with the tame dog forms a very useful breed for emu-hunting, and many even of the pure ones are caught young, tamed by the natives, and bred up to hunt emus and kangaroos. They have as many pups as the tame dog, littering either in some hollow log, deserted ant-hill, hole in the ground, or thick brush. They will hunt, kill, and devour a tame dog also, if a troop of them can catch him alone. A settler in the interior informed me, that, while out hunting one morning, he observed his dog running direct towards him at full speed, with two large native dogs close at his heels; and so eager were they to seize their prey, that his own dog was actually sheltered between his legs, and the native dogs within pistol-shot, before they perceived their danger. Hence he was enabled to shoot one of them. The native cat is the only other carnivorous animal we possess; but its depredations extend no farther than the poultry-yard. It is small and long-bodied, with a long tail, claws like a common cat, a nose like a pig, striped down the sides with brown and black, and dotted over with white spots. It climbs trees and preys on birds while they sleep, being a night animal.
