Previous to leaving England I remember to have frequently heard it asserted, that the discovery of mines was one of the secondary objects of the expedition. Perhaps there are mines; but as no person competent to form a decision is to be found among us, I wish no one to adopt an idea, that I mean to impress him with such a belief, when I state, that individuals, whose judgements are not despicable, are willing to think favourably of this conjecture, from specimens of ore seen in many of the stones picked up here. I cannot quit this subject without regretting, that some one capable of throwing a better light on it, is not in the colony. Nor can I help being equally concerned, that an experienced botanist was not sent out, for the purpose of collecting and describing the rare and beautiful plants with which the country abounds. Indeed, we flattered ourselves, when at the Cape of Good Hope, that Mason, the King's botanical gardener, who was employed there in collecting for the royal nursery at Kew, would have joined us, but it seems his orders and engagements prevented him from quitting that beaten track, to enter on this scene of novelty and variety.
To the naturalist this country holds out many invitations. Birds, though not remarkably numerous, are in great variety, and of the most exquisite beauty of plumage, among which are the cockatoo, lory, and parroquet; but the bird which principally claims attention is, a species of ostrich, approaching nearer to the emu of South America than any other we know of. One of them was shot, at a considerable distance, with a single ball, by a convict employed for that purpose by the Governor; its weight, when complete, was seventy pounds, and its length from the end of the toe to the tip of the beak, seven feet two inches, though there was reason to believe it had not attained its full growth. On dissection many anatomical singularities were observed: the gall-bladder was remarkably large, the liver not bigger than that of a barn-door fowl, and after the strictest search no gizzard could be found; the legs, which were of a vast length, were covered with thick, strong scales, plainly indicating the animal to be formed for living amidst deserts; and the foot differed from an ostrich's by forming a triangle, instead of being cloven.
Goldsmith, whose account of the emu is the only one I can refer to, says, "that it is covered from the back and rump with long feathers, which fall backward, and cover the anus; these feathers are grey on the back, and white on the belly." The wings are so small as hardly to deserve the name, and are unfurnished with those beautiful ornaments which adorn the wings of the ostrich: all the feathers are extremely coarse, but the construction of them deserves notice—they grow in pairs from a single shaft, a singularity which the author I have quoted has omitted to remark. It may be presumed, that these birds are not very scarce, as several have been seen, some of them immensely large, but they are so wild, as to make shooting them a matter of great difficulty. Though incapable of flying, they run with such swiftness, that our fleetest greyhounds are left far behind in every attempt to catch them. The flesh was eaten, and tasted like beef.
Besides the emu, many birds of prodigious size have been seen, which promise to increase the number of those described by naturalists, whenever we shall be fortunate enough to obtain them; but among these the bat of the Endeavour River is not to be found. In the woods are various little songsters, whose notes are equally sweet and plaintive.
Of quadrupeds, except the kangaroo, I have little to say. The few met with are almost invariably of the opossum tribe, but even these do not abound. To beasts of prey we are utter strangers, nor have we yet any cause to believe that they exist in the country. And happy it is for us that they do not, as their presence would deprive us of the only fresh meals the settlement affords, the flesh of the kangaroo. This singular animal is already known in Europe by the drawing and description of Mr. Cook. To the drawing nothing can be objected but the position of the claws of the hinder leg, which are mixed together like those of a dog, whereas no such indistinctness is to be found in the animal I am describing. It was the Chevalier De Perrouse who pointed out this to me, while we were comparing a kangaroo with the plate, which, as he justly observed, is correct enough to give the world in general a good idea of the animal, but not sufficiently accurate for the man of science.
Of the natural history of the kangaroo we are still very ignorant. We may, however, venture to pronounce this animal, a new species of opossum, the female being furnished with a bag, in which the young is contained; and in which the teats are found. These last are only two in number, a strong presumptive proof, had we no other evidence, that the kangaroo brings forth rarely more than one at a birth. But this is settled beyond a doubt, from more than a dozen females having been killed, which had invariably but one formed in the pouch. Notwithstanding this, the animal may be looked on as prolific, from the early age it begins to breed at, kangaroos with young having been taken of not more than thirty pounds weight; and there is room to believe that when at their utmost growth, they weigh not less than one hundred and fifty pounds. A male of one hundred and thirty pounds weight has been killed, whose dimensions were as follows:
Feet. Inches.
Extreme length 7 3
Ditt of the tail 3 4 1/2
Ditto of the hinder legs 3 2
Ditto of the fore paws 1 7 1/2
Circumference of the tail of the root 1 5
After this perhaps I shall hardly be credited, when I affirm that the kangaroo on being brought forth is not larger than an English mouse. It is, however, in my power to speak positively on this head, as I have seen more than one instance of it.
In running, this animal confines himself entirely to his hinder, legs, which are possessed with an extraordinary muscular power. Their speed is very great, though not in general quite equal to that of a greyhound; but when the greyhounds are so fortunate as to seize them, they are incapable of retaining their hold, from the amazing struggles of the animal. The bound of the kangaroo, when not hard pressed, has been measured, and found to exceed twenty feet.
At what time of the year they copulate, and in what manner, we know not: the testicles of the male are placed contrary to the usual order of nature.
