I particularly noticed some enormous sh.e.l.ls--carapaces (turtle and tortoise species) the diameter of which exceeded fifteen feet.

They had in past ages belonged to those gigantic Glyptodons of the Pliocene period, of which the modern turtle is but a minute specimen. In addition, the whole soil was covered by a vast quant.i.ty of stony relics, having the appearance of flints worn by the action of the waves, and lying in successive layers one above the other. I came to the conclusion that in past ages the sea must have covered the whole district. Upon the scattered rocks, now lying far beyond its reach, the mighty waves of ages had left evident marks of their pa.s.sage.

On reflection, this appeared to me partially to explain the existence of this remarkable ocean, forty leagues below the surface of the earth's crust. According to my new, and perhaps fanciful, theory, this liquid ma.s.s must be gradually lost in the deep bowels of the earth. I had also no doubt that this mysterious sea was fed by infiltration of the ocean above, through imperceptible fissures.

Nevertheless, it was impossible not to admit that these fissures must now be nearly choked up, for if not, the cavern, or rather the immense and stupendous reservoir, would have been completely filled in a short s.p.a.ce of time. Perhaps even this water, having to contend against the acc.u.mulated subterraneous fires of the interior of the earth, had become partially vaporized. Hence the explanation of those heavy clouds suspended over our heads, and the superabundant display of that electricity which occasioned such terrible storms in this deep and cavernous sea.

This lucid explanation of the phenomena we had witnessed appeared to me quite satisfactory. However great and mighty the marvels of nature may seem to us, they are always to be explained by physical reasons.

Everything is subordinate to some great law of nature.

It now appeared clear that we were walking upon a kind of sedimentary soil, formed like all the soils of that period, so frequent on the surface of the globe, by the subsidence of the waters. The Professor, who was now in his element, carefully examined every rocky fissure. Let him only find an opening and it directly became important to him to examine its depth.

For a whole mile we followed the windings of the Central Sea, when suddenly an important change took place in the aspect of the soil. It seemed to have been rudely cast up, convulsionized, as it were, by a violent upheaving of the lower strata. In many places, hollows here and hillocks there attested great dislocations at some other period of the terrestrial ma.s.s.

We advanced with great difficulty over the broken ma.s.ses of granite mixed with flint, quartz, and alluvial deposits, when a large field, more even than a field, a plain of bones, appeared suddenly before our eyes! It looked like an immense cemetery, where generation after generation had mingled their mortal dust.

Lofty barrows of early remains rose at intervals. They undulated away to the limits of the distant horizon and were lost in a thick and brown fog.

On that spot, some three square miles in extent, was acc.u.mulated the whole history of animal life--scarcely one creature upon the comparatively modern soil of the upper and inhabited world had not there existed.

Nevertheless, we were drawn forward by an all-absorbing and impatient curiosity. Our feet crushed with a dry and crackling sound the remains of those prehistoric fossils, for which the museums of great cities quarrel, even when they obtain only rare and curious morsels. A thousand such naturalists as Cuvier would not have sufficed to recompose the skeletons of the organic beings which lay in this magnificent osseous collection.

I was utterly confounded. My uncle stood for some minutes with his arms raised on high towards the thick granite vault which served us for a sky. His mouth was wide open; his eyes sparkled wildly behind his spectacles (which he had fortunately saved), his head bobbed up and down and from side to side, while his whole att.i.tude and mien expressed unbounded astonishment.

He stood in the presence of an endless, wondrous, and inexhaustibly rich collection of antediluvian monsters, piled up for his own private and peculiar satisfaction.

Fancy an enthusiastic lover of books carried suddenly into the very midst of the famous library of Alexandria burned by the sacrilegious Omar, and which some miracle had restored to its pristine splendor! Such was something of the state of mind in which Uncle Hardwigg was now placed.

For some time he stood thus, literally aghast at the magnitude of his discovery.

But it was even a greater excitement when, darting wildly over this ma.s.s of organic dust, he caught up a naked skull and addressed me in a quivering voice:

"Harry, my boy--Harry--this is a human head!"

"A human head, Uncle!" I said, no less amazed and stupefied than himself.

"Yes, nephew. Ah! Mr. Milne-Edwards--ah! Mr. De Quatref.a.ges--why are you not here where I am--I, Professor Hardwigg!"

CHAPTER 35

DISCOVERY UPON DISCOVERY

In order fully to understand the exclamation made by my uncle, and his allusions to these ill.u.s.trious and learned men, it will be necessary to enter into certain explanations in regard to a circ.u.mstance of the highest importance to paleontology, or the science of fossil life, which had taken place a short time before our departure from the upper regions of the earth.

On the 28th of March, 1863, some navigators under the direction of M.

Boucher de Perthes, were at work in the great quarries of Moulin-Quignon, near Abbeville, in the department of the Somme, in France. While at work, they unexpectedly came upon a human jawbone buried fourteen feet below the surface of the soil. It was the first fossil of the kind that had ever been brought to the light of day. Near this unexpected human relic were found stone hatchets and carved flints, colored and clothed by time in one uniform brilliant tint of verdigris.

The report of this extraordinary and unexpected discovery spread not only all over France, but over England and Germany. Many learned men belonging to various scientific bodies, and noteworthy among others, Messrs. Milne-Edwards and De Quatref.a.ges, took the affair very much to heart, demonstrated the incontestable authenticity of the bone in question, and became--to use the phrase then recognized in England--the most ardent supporters of the "jawbone question."

To the eminent geologists of the United Kingdom who looked upon the fact as certain--Messrs. Falconer, Buck, Carpenter, and others--were soon united the learned men of Germany, and among those in the first rank, the most eager, the most enthusiastic, was my worthy uncle, Professor Hardwigg.

The authenticity of a human fossil of the Quaternary period seemed then to be incontestably demonstrated, and even to be admitted by the most skeptical.

This system or theory, call it what you will, had, it is true, a bitter adversary in M. Elie de Beaumont. This learned man, who holds such a high place in the scientific world, holds that the soil of Moulin-Quignon does not belong to the diluvium but to a much less ancient stratum, and, in accordance with Cuvier in this respect, he would by no means admit that the human species was contemporary with the animals of the Quaternary epoch. My worthy uncle, Professor Hardwigg, in concert with the great majority of geologists, had held firm, had disputed, discussed, and finally, after considerable talking and writing, M. Elie de Beaumont had been pretty well left alone in his opinions.

We were familiar with all the details of this discussion, but were far from being aware then that since our departure the matter had entered upon a new phase. Other similar jawbones, though belonging to individuals of varied types and very different natures, had been found in the movable grey sands of certain grottoes in France, Switzerland, and Belgium; together with arms, utensils, tools, bones of children, of men in the prime of life, and of old men. The existence of men in the Quaternary period became, therefore, more positive every day.

But this was far from being all. New remains, dug up from the Pliocene or Tertiary deposits, had enabled the more far-seeing or audacious among learned men to a.s.sign even a far greater degree of antiquity to the human race. These remains, it is true, were not those of men; that is, were not the bones of men, but objects decidedly having served the human race: shinbones, thighbones of fossil animals, regularly scooped out, and in fact sculptured--bearing the unmistakable signs of human handiwork.

By means of these wondrous and unexpected discoveries, man ascended endless centuries in the scale of time; he, in fact, preceded the mastodon; became the contemporary of the Elephas meridionalis--the southern elephant; acquired an antiquity of over a hundred thousand years, since that is the date given by the most eminent geologists to the Pliocene period of the earth. Such was then the state of paleontologic science, and what we moreover knew sufficed to explain our att.i.tude before this great cemetery of the plains of the Hardwigg Ocean.

It will now be easy to understand the Professor's mingled astonishment and joy when, on advancing about twenty yards, he found himself in the presence of, I may say face to face with, a specimen of the human race actually belonging to the Quaternary period!

It was indeed a human skull, perfectly recognizable. Had a soil of very peculiar nature, like that of the cemetery of St. Michel at Bordeaux, preserved it during countless ages? This was the question I asked myself, but which I was wholly unable to answer. But this head with stretched and parchmenty skin, with the teeth whole, the hair abundant, was before our eyes as in life!

I stood mute, almost paralyzed with wonder and awe before this dread apparition of another age. My uncle, who on almost every occasion was a great talker, remained for a time completely dumfounded. He was too full of emotion for speech to be possible. After a while, however, we raised up the body to which the skull belonged. We stood it on end. It seemed, to our excited imaginations, to look at us with its terrible hollow eyes.

After some minutes of silence, the man was vanquished by the Professor.

Human instincts succ.u.mbed to scientific pride and exultation. Professor Hardwigg, carried away by his enthusiasm, forgot all the circ.u.mstances of our journey, the extraordinary position in which we were placed, the immense cavern which stretched far away over our heads. There can be no doubt that he thought himself at the Inst.i.tution addressing his attentive pupils, for he put on his most doctorial style, waved his hand, and began:

"Gentlemen, I have the honor on this auspicious occasion to present to you a man of the Quaternary period of our globe. Many learned men have denied his very existence, while other able persons, perhaps of even higher authority, have affirmed their belief in the reality of his life.

If the St. Thomases of paleontology were present, they would reverentially touch him with their fingers and believe in his existence, thus acknowledging their obstinate heresy. I know that science should be careful in relation to all discoveries of this nature. I am not without having heard of the many Barnums and other quacks who have made a trade of suchlike pretended discoveries. I have, of course, heard of the discovery of the kneebones of Ajax, of the pretended finding of the body of Orestes by the Spartiates, and of the body of Asterius, ten spans long, fifteen feet--of which we read in Pausanias.

"I have read everything in relation to the skeleton of Trapani, discovered in the fourteenth century, and which many persons chose to regard as that of Polyphemus, and the history of the giant dug up during the sixteenth century in the environs of Palmyra. You are well aware as I am, gentlemen, of the existence of the celebrated a.n.a.lysis made near Lucerne, in 1577, of the great bones which the celebrated Doctor Felix Plater declared belonged to a giant about nineteen feet high. I have devoured all the treatises of Ca.s.sanion, and all those memoirs, pamphlets, speeches, and replies published in reference to the skeleton of Teutobochus, king of the Cimbri, the invader of Gaul, dug out of a gravel pit in Dauphine, in 1613. In the eighteenth century I should have denied, with Peter Campet, the existence of the preadamites of Scheuchzer. I have had in my hands the writing called Gigans--"

Here my uncle was afflicted by the natural infirmity which prevented him from p.r.o.nouncing difficult words in public. It was not exactly stuttering, but a strange sort of const.i.tutional hesitation.

"The writing named Gigans--" he repeated.

He, however, could get no further.

"Giganteo--"

Impossible! The unfortunate word would not come out. There would have been great laughter at the Inst.i.tution, had the mistake happened there.

"Gigantosteology!" at last exclaimed Professor Hardwigg between two savage growls.

Having got over our difficulty, and getting more and more excited--

"Yes, gentlemen, I am well acquainted with all these matters, and know, also, that Cuvier and Blumenbach fully recognized in these bones the undeniable remains of mammoths of the Quaternary period. But after what we now see, to allow a doubt is to insult scientific inquiry. There is the body; you can see it; you can touch it. It is not a skeleton, it is a complete and uninjured body, preserved with an anthropological object."

I did not attempt to controvert this singular and astounding a.s.sertion.

"If I could but wash this corpse in a solution of sulphuric acid,"
