Part 5

"3. They existed in considerable numbers,--(an observation which has since been abundantly confirmed.)

"4. It may be inferred that this bird was long-lived, and that it was many years before it attained its full size. (The writer grounds this inference on the disparity in dimensions of the corresponding bones, supposing that they all belonged to one and the same species; which, however, was an erroneous assumption.)

"5. The greatest height of the bird was probably not less than fourteen or sixteen feet. The leg-bones now sent give the height of six feet to the root of the tail.

"Within the last few days I have obtained a piece of information worthy of notice. Happening to speak to an American about these bones, he told me that the bird is still in existence in the neighbourhood of Cloudy Bay, in Cook's Straits. He said that the natives there had mentioned to an Englishman belonging to a whaling party, that there was a bird of extraordinary size to be seen only at night, on the side of a hill near the place, and that he, with a native and a second Englishman, went to the spot; that, after waiting some time, they saw the creature at a little distance, which they describe as being about fourteen or sixteen feet high. One of the men proposed to go nearer and shoot, but his companion was so exceedingly terrified, or perhaps both of them, that they were satisfied with looking at the bird, when, after a little time, it took the alarm, and strode off up the side of the mountain.

"This incident might not have been worth mentioning, had it not been for the extraordinary agreement in point of the size of the bird [with my deductions from the bones]. Here are the bones which will satisfy you that such a bird has been in existence; and there is said to be the living bird, the supposed size of which, given by an independent witness, precisely agrees."

The story told of the whaler appears to me to bear marks of truth. The bold essay to explore, the terror inspired by the gigantic figure, especially in the solemnity of night, the description of the manners of the bird running and striding, so like those of the Apteryx, with which its bones shew the Moa to have been closely allied, and the inglorious return of the party without achieving any exploit, are all too natural to permit the thought that no more than inventive power has been at work.

And well may the colossus have inspired fear. The bones sent to London greatly exceed in bulk those of the largest horse. The leg-bone of a tall man is about one foot four inches in length, and the thigh of O'Brien, the Irish giant, whose skeleton, eight feet high, is mounted in the Museum of the Royal College of Surgeons, is not quite two feet. But the leg-bone (tibia) of the Dinornis we know measured as much as two feet ten inches, and we have no reason to suppose, considering the disparity that exists in the specimens examined, that we have seen by any means the largest.

Additional reason for supposing these magnificent birds to have existed not long ago, is found in the fact that specimens of their eggs have been preserved. The circumstances attendant on the discovery and identification of these possess a remarkable interest. In the volcanic sand of New Zealand Mr Walter Mantell found a gigantic egg, which we may reasonably infer to be that of either Dinornis or Palapteryx, of the magnitude of which he gives us a familiar idea by saying that his hat would have been but just large enough to have served as an egg-cup for it. This is the statement of a man of science, and therefore we may assume an approximate degree of precision in the comparison.

I do not know the size of Mr Mantell's hat, but I find that the transverse diameter of my own is six inches or a little more. If we may take this as the shorter diameter of the ovoid, the longer would probably be about eight and a half inches; dimensions considerably greater than those of the Ostrich's egg (which are about six and a quarter in length), but not what we should have expected from a bird from twelve to fourteen feet in height. And this the rather when we consider that the egg of the New Zealand Apteryx, to which these birds manifest a very close affinity, is one of dimensions that are quite surprising in proportion to the bulk of the bird. The Apteryx is about as big as a turkey, standing two feet in height, but its egg measures four inches ten lines by three inches two lines in the respective diameters. The egg of the Dinornis giganteus, to bear the same ratio to the bird as this, would be of the incredible length of two feet and a half, by a breadth of one and three quarters! Possibly this specimen, though indubitably the egg of one of this great family of extinct birds, may after all be that of one of the subordinate species.

But about the same time as Mr Mantell's discovery, one of equal interest was made in Madagascar. The master of a French ship obtained, in 1850, from natives of the island, three eggs, of far greater size, and fragments of the leg-bones of an immense bird. These, on their arrival at Paris, formed the subjects of valuable investigations by M. Isidore Geoffroy St Hilaire and Professor Owen.

The native statement was, that one of the eggs had been found entire in the bed of a torrent, among the debris of a land-slip; that a second egg, with some fragments of bone, was subsequently found in a formation which is stated to be alluvial; a third egg, which the natives had perforated at one end, and used as a vessel, was also found. This last egg was broken in the carriage, the other two arrived in Europe entire.

These two, though nearly alike in size, differed considerably in their relative proportions and shape, the one being shorter and thicker, with more equal ends than the other. The following table shews the dimensions of both compared with those of an ostrich's egg:--

Ovoid egg. Ellipsoid egg. Ostrich egg. ft. in. li. ft. in. li. ft. in. li. Longer circumference 2 10 9 2 9 6 1 6 0 Shorter circumference 2 4 3 2 5 6 1 4 6 Extreme length 1 0 8 1 0 5 0 6 4

M. Geoffroy St Hilaire estimates the larger of the two to contain 10-1/8 quarts, or the contents of nearly six eggs of the Ostrich, or sixteen of the Cassowary, or a hundred and forty-eight of the Hen, or fifty thousand of the Humming bird.

The fragments of bone indicated a bird of the same natural affinities as the New Zealand colossi, and of dimensions not widely remote from theirs. Professor Owen thinks that it did not exceed in height or size Dinornis giganteus, and that there is a probability that it was slightly smaller. The Madagascar bird has been named Æpyornis maximus.

The fragments of the egg of the New Zealand bird (still uncertain as to the species to which it is to be referred) shew that the shell was absolutely thinner, and therefore relatively much thinner than that of the Ostrich's egg; the air-pores, too, have a different form, being linear, instead of round, and the surface is smoother. In these qualities, the New Zealand egg resembles that of the Apteryx; in the thickness and roughness of the egg of Æpyornis there is more similarity to those of the Ostrich and Cassowary. The colour of the Madagascar egg is a dull greyish yellow; but it is possible that this may be derived from the soil in which it has long been imbedded. The fragments of the New Zealand egg are white, like the eggs of the Apteryx and Ostrich: those of the Emu and Cassowary are light green.

The willing fancy suggests the possibility that, in an island of such immensity as Madagascar, possessing lofty mountain-ranges, covered with the most magnificent forests, where civilised man has only yet touched one or two spots on the seaward borders, but where these slight explorations have educed so many wondrous animals, so many strange forms of vegetable life, the noble Æpyornis may yet be stalking with giant stride along the fern-fringed hill-sides, or through the steaming thickets; though in the more contracted area of New Zealand its equally ponderous cousins, the Dinornis and the Palapteryx, may have sunk beneath the persevering persecutions of man.

Yet another item of evidence bearing on the recent if not present existence of these great fowls has recently come to light:--the most interesting discovery that one of the genera whose fossil remains had been found associated with theirs is really extant in New Zealand. I refer to the Notornis.

At a meeting of the Zoological Society of London, held on the 13th November 1850, Dr Mantell made the following communication relative to this discovery:--

"It was in the course of last year, on the occasion of my son's second visit to the south of the middle island, that he had the good fortune to secure the recent Notornis, which I now submit, having previously placed it in the hands of the eminent ornithologist Mr Gould, to figure and describe. This bird was taken by some sealers who were pursuing their avocations in Dusky Bay. Perceiving the trail of a large and unknown bird on the snow, with which the ground was then covered, they followed the footprints till they obtained a sight of the Notornis, which their dogs instantly pursued, and, after a long chase, caught alive in the gully of a sound behind Resolution Island. It ran with great speed, and on being captured uttered loud screams, and fought and struggled violently. It was kept alive three or four days on board the schooner, and then killed, and the body roasted and eaten by the crew, each partaking of the dainty, which was declared to be delicious. The beak and legs were of a bright red colour. My son secured the skin, together with very fine specimens of the Kapapo or ground parrot (Strigops), a pair of Huias (Neomorpha), and two species of Kiwikiwi, namely Apteryx Australis, and A. Oweni. The latter very rare bird is now added to the collection of the British Museum."

"Mr Walter Mantell states, that, according to the native traditions, a large Rail was contemporary with the Moa, and formed a principal article of food among their ancestors. It was known to the North Islanders by the name 'Moho,' and to the South Islanders by that of 'Takahe;' but the bird was considered by both natives and Europeans to have been long since exterminated by the wild cats and dogs; not an individual having been seen or heard of since the arrival of the English colonists. On comparing the head of the bird with the fossil cranium, and mandibles, and the figures and descriptions in the 'Zoological Transactions' (Plate lvi.), my son was at once convinced of their identity. It may not be irrelevant to add, that in the course of Mr Walter Mantell's journey from Banks's Peninsula along the coast to Otago, he learned from the natives that they believed there still existed in that country the only indigenous terrestrial quadruped, except a species of rat, which there are any reasonable grounds for concluding New Zealand ever possessed. While encamping at Arowenua, in the district of Timaru, the Maoris assured them that about ten miles inland there was a quadruped which they called Káureke, and that it was formerly abundant, and often kept by their ancestors in a domestic state as a pet animal. It was described as about two feet in length, with coarse grizzly hair; and must have more nearly resembled the otter or badger than the beaver or the Ornithorhynchus, which the first accounts seem to suggest as the probable type. The offer of a liberal reward induced some of the Maoris to start for the interior of the country where the Káureke was supposed to be located; but they returned without having obtained the slightest trace of the existence of such an animal. My son, however, expresses his belief in the native accounts, and that, if the creature no longer exists, its extermination is of very recent date. In concluding this brief narrative of the discovery of a genus of birds once contemporary with the colossal Moa, and hitherto only known by its fossil remains, I beg to remark that this highly interesting fact tends to confirm the conclusions expressed in my communication to the Geological Society, namely, that the Dinornis, Palapteryx, and related forms, were coeval with some of the existing species of birds peculiar to New Zealand, and that their final extinction took place at no very distant period, and long after the advent of the aboriginal Maoris."

Mr Gould then read a paper pointing out the zoological characters of the bird discovered by Mr Mantell, which he had no hesitation in identifying as the species formerly characterised, from its osseous remains, by Professor Owen, under the name of Notornis Mantelli. Mr Gould, in adverting to the extreme interest with which the present existence of a species which was certainly contemporary with the Moa must be regarded, pointed out, from the preserved skin, which was on the table, how accurate a prevision of its character had been made by Professor Owen, when investigating the fragments from which our first knowledge of it had been derived.

At length I come home to Great Britain and Ireland--the "nice little, tight little islands" where so many of our sympathies properly centre, where natural-history facts and all other facts interest us so much more than parallel facts elsewhere, and where, above all, there are so many more lights streaming into the darkness, and bringing out truth. Let us again look back to the period of the Bison, and Reindeer, and Elk, of the Elephant, and Hippopotamus, and Rhinoceros, of the Lion and the Hyena, and the great Cave Bear, and search among the vanishing traces of the far past for glimpses of evidence when their age ceased to be.

Some dim light falls on the obscurity from the discovery of the fossil remains of man himself--the human bones found by Dr Schmerling in a cavern near Liege, the remains mentioned by M. Marcel de Serres and others in several caverns in France, associated with fossil relics of this period. But more from the occurrence of flints, apparently fashioned by human art, in superficial deposits, together with the same extinct fossils of the tertiary. Even at the very moment that I write this sheet, my eye falls on the report of an important meeting of the Ethnological Society, for the purpose of discussing this very subject of "The flint implements found associated with the bones of extinct animals in the Drift." Many of the leading geologists and archæologists were present, for the matter has become one of absorbing interest, conflicting, as the facts seem to do, with some assumptions received as unquestioned verities in Geology.

These flints, which seem indubitably to have been chipped into the forms of arrow-heads, lance-heads, and the like, have been found in France in large numbers, as also in other parts of the continent, and in England. They resemble those still used by some savage tribes. In this very neighbourhood, as in the cavern called Kent's Hole near Torquay, and in one more recently examined at Brixham, they are found mixed up with the bones of the Rhinoceros, of the Cave Bear, and the Hyena, At Menchecourt, near Abbeville, they occur in a deposit of sand, sandy clay, and marl, with bones of the same animals, and others, their contemporaries. Concerning this bed, Mr Prestwich, in a paper read before the Royal Society, May 26, 1859, says that it must be referred to those usually designated as post pliocene, but that the period of its deposit was anterior to that of the surface assuming its present outline, so far as some of its minor features are concerned. "He does not, however, consider that the facts of necessity carry man back in past time more than they bring forward the great extinct mammals towards our own time, the evidence having reference only to relative, and not to absolute time; and he is of opinion that many of the later geological changes may have been sudden, or of shorter duration than generally considered. In fact, from the evidence here exhibited, and from all that he knows regarding the drift phenomena generally, the author sees no reason against the conclusion that this period of man and the extinct mammals--supposing their contemporaneity to be proved--was brought to a sudden end by a temporary inundation of the land; on the contrary, he sees much to support such a view on purely geological considerations."

At the meeting of the Ethnological Society just held, there seems to have been an increasing tendency to admit the hypothesis of the continuance of the Mammalia of the Tertiary into the human era. Mr Evans, who exhibited specimens taken at a depth of twenty to thirty feet, from a stratum of coarse fresh-water gravel, lying on chalk, and containing an entire skeleton of an extinct Rhinoceros, and overlaid by sandy marl containing existing shells, shewed that the deposit had certainly not been disturbed till the present time, so that the gravel, the bones, and the flints had been deposited coetaneously. He suggested "that the animals supposed to have become extinct before man was created might have continued to exist to more recent periods than had been admitted." And this opinion found support from other leading geologists.

That this conclusion would throw the existence of man to an era far higher than that assigned to him by the inspired Word, is, I know, generally held; and certain investigations, made in the alluvial deposit of the Nile, are considered to prove that man has been living in a state of comparative civilisation in the Nile Valley for the last 13,500 years. But that conclusion absolutely rests on the supposition that the rate of increase formed by the annual deposit of the Nile mud has been always exactly the same as now,--a supposition, not only without the least shadow of proof, but also directly contrary to the highest probability, nay, certainty, in the estimation of those who believe in the Noachian deluge. For surely the drainage of the entire plain of North Africa after that inundation must have produced an alluvium of vast thickness in a very brief time; while beneath that deposit the works of the antediluvian world might well be buried. Yet the possibility of there ever having been any greater rate of deposit than within the last 3000 years, the recorder of those investigations, in his unseemly haste to prove the Bible false, strangely leaves wholly out of his consideration.

So, doubtless, concerning other deposits containing fossil remains, whose extreme antiquity is assumed from the known rate of surface-increase now, we ought to remember that we have not a tittle of proof that the rate of increase has not at certain remote periods been suddenly and immensely augmented. There are many facts on record which tend to shew that the rate at which geologic changes take place in certain localities affords no reliable data whatever to infer that at which phenomena apparently quite parallel have occurred in other localities. An upheaval or a subsidence of one part of a country may rapidly effect a great change in the amount of soil or gravel precipitated by streams, without destroying or changing their channels, and yet the deposit may be made sufficiently gradually to allow the burial of shells or of bones of creatures which lived and died on the spot.
