Figure 1 represents the Jura before the Alps were raised, with the Cretaceous deposits accumulating beneath the sea at its base. The line marked S indicates the ocean-level; the letter c, the Cretaceous deposits; the letter j, the Jurassic strata, lifted on the side of the mountain.


Figure 2 represents the Jura at the present time, when the later upheavals have lifted the Jurassic strata to a sharper inclination with the Cretaceous deposits, now raised and forming the lower slope of the mountain, at the base of which is the Lake of Neufchatel.


Although this change of inclination is hardly perceptible, as one looks up against the face of the Jura range, there is a transverse cut across it which seems intended to give us a diagram of its internal structure. Behind the city of Neufchatel rises the mountain of Chaumont, so called from its bald head, for neither tree nor shrub grows on its summit. Straight through this mountain, from its northern to its southern side, there is a natural road, formed by a split in the mountain from top to bottom. In this transverse cut, which forms one of the most romantic and picturesque gorges leading into the heart of the Jura range, you get a profile view of the change in the inclination of the strata, and can easily distinguish the point of juncture between the two sets of deposits. But even after this dislocation of strata had been perceived, it was not known that it indicated the commencement of a new epoch, and it is here that my own share in the work, such as it is, belongs. Accustomed as a boy to ramble about in the beautiful gorges and valleys of the Jura, and in riper years, as my interest in science increased, to study its formation with closer attention, this difference in the inclination of the slope had not escaped my observation. I was, however, still more attracted by the fossils it contained than by its geological character: and, indeed, there is no better locality for the study of extinct forms of life than the Jura. In all its breaks and ravines, wherever the inner surface of the rock is exposed, it is full of organic remains; and to take a handful of soil from the road-side is often to gather a handful of shells. It is actually built of the remains of animals, and there are no coral reefs in existing seas presenting a better opportunity for study to the naturalist than the coral reefs of the Jura. Being already tolerably familiar with the fossils of the Jura, it occurred to me to compare those of the upper and lower slope; and to my surprise I found that they were everywhere different, and that those of the lower slope were invariably Cretaceous in character, while those of the upper slope were Jurassic. In the course of this investigation I discovered three periods in the Cretaceous and four in the Jurassic epoch, all characterized by different fossils. This led to a more thorough investigation of the different sets of strata, resulting in the establishment by D'Orbigny of a still greater number of periods, marked by the successive deposits of the Jurassic and Cretaceous seas, all of which contained different organic remains. The attention of geologists being once turned in this direction, the other epochs were studied with the same view, and all were found to be susceptible of division into a greater or less number of such periods.

I have dwelt at greater length on the Jurassic and Cretaceous divisions, because I believe that we have in the relation of these two epochs, as well as in that of the Cretaceous epoch with the Tertiary immediately following it, facts which are very important in their bearing on certain questions, now loudly discussed, not only by scientific men, but by all who are interested in the mode of origin of animals. Certainly, in the inland seas of the Cretaceous and subsequent Tertiary times, where we can trace in the same sheet of water not only the different series of deposits belonging to two successive epochs in immediate juxtaposition, but those belonging to all the periods included within these epochs, with the organic remains contained in each,—there, if anywhere, we should be able to trace the transition-types by which one set of animals is said to have been developed out of the preceding. We hear a great deal of the interruption in geological deposits, of long intervals, the record of which has vanished, and which may contain those intermediate links for which we vainly seek. But here there is no such gap in the evidence. In the very same sheets of water, covering limited areas, we have the successive series of deposits containing the remains of animals which continue perfectly unchanged during long intervals, and then, with a more or less violent shifting of the surface,4 traceable by the consequent discordance of the strata, is introduced an entirely new set of animals, differing as much from those immediately preceding them as do those of the present period from the old Creation, (our predecessors, but not our ancestors,) traced by Cuvier in the Tertiary deposits underlying those of our own geological age. I subjoin here a tabular view giving the Epochs in their relation to the Ages, and indicating, at least approximately, the number of Periods contained in each Epoch.



It will be noticed by those who have any knowledge of geological divisions, that in this diagram I consider the Carboniferous epoch as forming a part of the Secondary age. Some geologists have been inclined, from the marked and peculiar character of its vegetation, to set it apart as forming in itself a distinct geological age, while others have united it with the Palæozoic age. For many years I myself adopted the latter of these two views, and associated the Carboniferous epoch with the Palæozoic age. But it is the misfortune of progress that one is forced not only to unlearn a great deal, but, if one has been in the habit of communicating his ideas to others, to destroy much of his own work. I now find myself in this predicament; and after teaching my students for years that the Carboniferous epoch belongs to the Palæozoic or Primary age, I am convinced—and this conviction grows upon me constantly as I free myself from old prepossessions and bias on the subject—that with the Carboniferous epoch we have the opening of the Secondary age in the history of the world. A more intimate acquaintance with organic remains has shown me that there is a closer relation between the character of the animal and vegetable world of the Carboniferous epoch, as compared with that of the Permian and Triassic epochs, than between that of the Carboniferous epoch and any preceding one. Neither do I see any reason for separating it from the others as a distinct age. The plants as well as the animals of the two subsequent epochs seem to me to show, on the contrary, the same pervading character, indicating that the Carboniferous epoch makes an integral part of that great division which I have characterized as the Secondary age.

Within the Periods there is a still more limited kind of geological division, founded upon the special character of local deposits. These I would call geological Formations, indicating concrete local deposits, having no cosmic character, but circumscribed within comparatively narrow areas, as distinguished from the other terms, Ages, Epochs, Periods, which have a more universal meaning, and are, as it were, cosmopolitan in their application. Let me illustrate my meaning by some formations of the present time. The accumulations along the coast of Florida are composed chiefly of coral sand, mixed of course with the remains of the animals belonging to that locality; those along the coast of the Southern States consist principally of loam, which the rivers bring down from their swamps and low, muddy grounds; those upon the shores of the Middle States are made up of clay from the disintegration of the eastern slopes of the Alleghanies; while those farther north, along our own coast, are mostly formed of sand from the New-England granites. Such deposits are the local work of one period, containing the organic remains belonging to the time and place. From the geological point of view, I would call them Formations; from the naturalist's point of view, I would call them Zoölogical Provinces.

Of course, in urging the application of these names, I do not intend to assume any dictatorship in the matter of geological nomenclature. But I do feel very strongly the confusion arising from an indiscriminate use of terms, and that, whatever names be selected as most appropriate or descriptive for these divisions, geologists should agree to use them in the same sense.

There is one other geological term, bequeathed to us by a great authority, and which cannot be changed for the better: I mean that of Geological Horizon, applied by Humboldt to the whole extent of any one geological division,—as, for instance, the Silurian horizon, including the whole extent of the Silurian epoch. It indicates one level in time, as the horizon which limits our view indicates the farthest extension of the plain on which we stand in space.

We left America at the close of the Carboniferous epoch, when the central part of the United States was already raised above the water. Let us now give a glance at Europe in those early days, and see how far her physical history has advanced. What European countries loom up for us out of the Azoic sea, corresponding in time and character to the low range of hills which first defined the northern boundary of the United States? what did the Silurian and Devonian epochs add to these earliest tracts of dry land in the Old World? and where do we find the coal basins which show us the sites of her Carboniferous forests? Since the relation between the epochs of comparative tranquillity and the successive upheavals has been so carefully traced in Europe, I will endeavor, while giving a sketch of that early European world, to point out, at the same time, the connection of the different systems of upheaval with the successive stratified deposits, without, however, entering into such details as must necessarily become technical and tedious.

 

In the European ocean of the Azoic epoch we find five islands of considerable size. The largest of these is at the North. Scandinavia had even then almost her present outlines; for Norway, Sweden, Finland, and Lapland, all of which are chiefly granitic in character, were among the first lands to be raised. Between Sweden and Norway, there is, however, still a large tract of land under water, forming an extensive lake or a large inland sea in the heart of the country. If the reader will take the trouble to look on any geological map of Europe, he will see an extensive patch of Silurian rock in the centre of Sweden and Norway. This represents that sheet of water gradually to be filled by the accumulation of Silurian deposits and afterwards raised by a later disturbance. There is another mass of land far to the southeast of this Scandinavian island, which we may designate as the Bohemian island, for it lies in the region now called Bohemia, though it includes, also, a part of Saxony and Moravia. The northwest corner of France, that promontory which we now call Bretagne, with a part of Normandy adjoining it, formed another island; while to the southeast of it lay the central plateau of France. Great Britain was not forgotten in this early world; for a part of the Scotch hills, some of the Welsh mountains, and a small elevation here and there in Ireland, already formed a little archipelago in that region. By a most careful analysis of the structure of the rocks in these ancient patches of land, tracing all the dislocations of strata, all the indications of any disturbance of the earth-crust whatsoever, Élie de Beaumont has detected and classified four systems of upheavals, previous to the Silurian epoch, to which he refers these islands in the Azoic sea. He has named them the systems of La Vendée, of Finistère, of Longmynd, and of Morbihan. These names have, for the present, only a local significance,—being derived, like so many of the geological names, from the places where the investigations of the phenomena were first undertaken,—but in course of time will, no doubt, apply to all the contemporaneous upheavals, wherever they may be traced, just as we now have Silurian, Devonian, Permian, and Jurassic deposits in America as well as in Europe.

The Silurian and Devonian epochs seem to have been instrumental rather in enlarging the tracts of land already raised than in adding new ones; yet to these two epochs is traced the upheaval of a large and important island to the northeast of France. We may call it the Belgian island, since it covered the ground of modern Belgium; but it also extended considerably beyond these limits, and included much of the Northern Rhine region. A portion only of this tract, to which belongs the central mass of the Vosges and the Black Forest, was lifted during the Silurian epoch,—which also enlarged considerably Wales and Scotland, the Bohemian island, the island of Bretagne, and Scandinavia. During this epoch the sheet of water between Norway and Sweden became dry land; a considerable tract was added to their northern extremity on the Arctic shore; while a broad band of Silurian deposits, lying now between Finland and Russia, enlarged that region. The Silurian epoch has been referred by Élie de Beaumont to the system of upheaval called by him the system of Westmoreland and Hundsrück,—again merely in reference to the spots at which these upheavals were first studied, the centres, as it were, from which the investigations spread. But in their geological significance they indicate all the oscillations and disturbances of the soil throughout the region over which the Silurian deposits have been traced in Europe. The Devonian epoch added greatly to the outlines of the Belgian island. To it belongs the region of the Ardennes, lying between France and Belgium, the Eifelgebirge, and a new disturbance of the Vosges, by which that region was also extended. The island of Bretagne was greatly increased by the Devonian deposits, and Bohemia also gained in dimensions, while the central plateau of France remained much the same as before. The changes of the Devonian epoch are traced by Élie de Beaumont to a system of upheavals called the Ballons of the Vosges and of Normandy,—so called from the rounded, balloon-like domes characteristic of the mountains of that time. To the Carboniferous epoch belong the mountain-systems of Forey, (to the west of Lyons,) of the North of England, and of the Netherlands. These three systems of upheaval have also been traced by Élie de Beaumont; and in the depressions formed between their elevations we find the coal-basins of Central France, of England, and of Germany. During all these epochs, in Europe as in America, every such dislocation of the surface was attended by a change in the animal creation.

If we take now a general view of the aspect of Europe at the close of the Carboniferous epoch, we shall see that the large island of Scandinavia is completed, while the islands of Bohemia and Belgium have approached each other by their gradual increase till they are divided only by a comparatively narrow channel. The island of Belgium, that of Bretagne, and that of the central plateau of France, form together a triangle, of which the plateau is the lowest point, while Belgium and Bretagne form the other two corners. Between the plateau and Belgium flows a channel, which we may call the Burgundian channel, since it covers old Burgundy; between the plateau and Bretagne is another channel, which from its position we may call the Bordeaux channel. The space inclosed between these three masses of land is filled by open sea. To trace the gradual closing of these channels and the filling up of the ocean by constantly increasing accumulations, as well as by upheavals, will be the object of the next article.

THE MUSICIAN

He did not move the hills and the rocks with his music, because those days are passed away,—the days when Orpheus had all Nature for his audience, when the audience would not keep its seat. In those days trees and rocks may have held less firm root in the soil: it was nearer the old Chaos-times, and they had not lost the habit of the whirling dance. The trees had not found their "continental" home, and the rocks were not yet wedded to their places: so they could each enjoy one more bachelor-dance before settling into their staid vegetable and mineral domestic happiness.

Our musician had no power, then, to move them from their place of ages: he did not stir them as much as the morning and evening breezes among the leaves, or the streams trickling down among the great rocks and wearing their way over precipices. But he moved men and women, of all natures and feelings. He could translate Bach and Beethoven, Mendelssohn and Mozart,—all the great poet-musicians that are silent now, and must be listened to through an interpreter. All the great people and all the little people came to hear him. A princess fell in love with him. She would have married him. She did everything but ask him to marry her. Indeed, some of his friends declared she did this; but that cannot be believed.

"You ought to be satisfied," said one of his friends to the musician, one day; "all the world admires you; money drops from the keys of your piano-forte; and a princess is in love with you."

"With me?" answered the musician; "with my music, perhaps. You talk nonsense, when you talk of her falling in love with me, of her marrying a poor musician. What then? To have one instrument more in her palace! Let her marry her piano-forte,—or her violin, if she objects to a quadruped!"

"You are as blind as Homer," said his friend. "Can't you see that her love is purely personal? Would she care to give a title to a pianist, if he were any other than Arnold Wulff? If you had other eyes in your head, or if there were another man inside even that same face of yours, the strains might flow out under your fingers like streams from Paradise, in vain, so far as her heart was concerned. Your voice is quite as persuasive as your music, with her."

"If so, why must she put a title in front of my name, before I am worthy of her?" asked Arnold. "She offers me some square miles of uninhabitable forest, because, as owner of them, I can wear a Von before my name. I can put it on as an actor on the stage wears a chapeau of the Quatorze time. It is one of the properties of the establishment. You may call it a livery of the palace, if you please. I may make love to her on the stage as 'My Lord.' But my own little meagre part of Arnold,—thank you, I prefer it, without my princess."

"And yet, if you have the palace, a princess is necessary. With your love of harmony, you yourself would not be pleased to see a cotton dress hanging across a damask couch, or rude manners interrupt a stately dinner. The sound of the titles clangs well as you are ushered up through the redoubled apartments. If the play is in the Quatorze time, let it be played out. A princess deserves at least a lord for a husband."

"Very well, if the question is of marriage," answered Arnold; "but in love, a woman loves a man, not a title; and if a woman marries as she loves, she marries the man, not the lordship."

"But this is a true princess," said his friend Carl.

"And a true princess," answered Arnold, "feels the peas under ever so many mattresses. She would not fall in love with a false lord, or degrade herself by marrying her scullion. But if she is a true princess, she sees what is lordly in her subject. If she loves him, already he is above her in station,—she looks up to him as her ideal. Whatever we love is above self. We pay unconscious homage to the object of our love. Already it becomes our lord or princess."

"I don't see, then," said Carl, "but that you are putting unnecessary peas in your shoes. It is this princeliness that your princess has discovered in you; and the titles she would give you are the signs of it, that she wishes you to wear before the world."

"And they never will make me lord or prince, since I am not born such," answered Arnold. "If I were born such, I would make the title grand and holy, so that men should see I was indeed prince and lord as well as man. As it is, I feel myself greater than either, and born to rule higher things. It would cramp me to put on a dignity for which I was not created. Already I am cramped by the circumstances out of which I was born. I cannot express strains of music that I hear in my highest dreams, because my powers are weak, and fail me as often the strings of my instrument fail my fingers. To put on any of the conventionalities of life, any of its honors, even the loves of life, would be to put on so many constraints the more."

"That is because you have never loved," said Carl.

"That may be," said Arnold,—"because I have never loved anything but music. Still that does not satisfy me,—it scarcely gives me joy; it gives me only longing, and oftener despair. I listen to it alone, in secret, until I am driven by a strange desire to express it to a great world. Then, for a few moments, the praise and flattery of crowds delight and exalt me,—but only to let me fall back into greater despair, into remorse that I have allowed the glorious art of music to serve me as a cup of self-exaltation."

"You, Arnold, so unmoved by applause?" said Carl.

"It is only an outside coldness," answered Arnold; "the applause heats me, excites me, till a moment when I grow to hate it. The flatteries of a princess and her imitating train turn my head, till an old choral strain, or a clutch that my good angel gives me, a welling-up of my own genius in my heart, comes to draw me back, to cool me, to taunt me as traitor, to rend me with the thought that in self I have utterly forgotten myself, my highest self."

 

"These are the frenzies with which one has to pay for the gift of genius," said Carl. "A cool temperament balances all that. If one enjoys coolly, one suffers as coolly. Take these fits of despair as the reverse side of your fate. She offers you by way of balance cups of joy and pleasure and success, of which we commonplace mortals scarcely taste a drop. When my peasant-maiden Rosa gives me a smile, I am at the summit of bliss; but my bliss-mountain is not so high that I fear a fall from it. If it were the princess that gladdened me so, I should expect a tumble into the ravine now and then, and would not mind the hard scramble up again, to reach the reward at the top."

"It would not be worth the pains," said Arnold; "a princess's smiles are not worth more than a peasant-girl's. I am tired of it all. I am going to find another world. I am going to England."

"You are foolish," answered Carl. "The world is no different there; there is as little heart in England as in Germany,—no more or less. You are just touching success here; do give it a good grasp."

"I am cloyed with it already," said Arnold.

"It is not that," said Carl. "You are a child crying for the moon. You would have your cake and eat it too. You want some one who shall love you, you alone,—who shall have no other thought but yours, no other dream than of you. Yet you are jealous for your music. If that is not loved as warmly, you begin to suspect your lover. It is the old proverb, 'Love me, love my dog.' But if your dog is petted too much, if we dream in last night's strains of music, forget you a moment in the world you have lifted us into,—why, then your back is turned directly; you upbraid us with following you for the sake of the music,—we have no personal love of you,—you are the violin or the fiddlestick!"

"You are right, old Carl," said Arnold. "I am all out of tune myself. I have not set my inward life into harmony with the world outside. It is true, at times I impress a great audience, make its feelings sway with mine; but, alas! it does not impress me in return. There is a little foolish joy at what you call success; but it lasts such a few minutes! I want to have the world move me; I do not care to move the world!"

"And will England move you more than Germany?" asked Carl; "will the hearts of a new place touch you more than those of home? The closer you draw to a man, the better you can read his heart, and learn that he has a heart. It is not the number of friends that gives us pleasure, but the warmth of the few."

"In music I find my real life," Arnold went on, "because in music I forget myself. Is music, then, an unreal life? In real life must self always be uppermost? It is so with me. In the world, with people, I am self-conscious. It is only in music that I am lifted above myself. When I am not living in that, I need activity, restlessness, change. This is why I must go away. Here I can easily be persuaded to become a conceited fool, a flattered hanger-on of a court."

We need scarcely tell of the musician's career in England. We are already familiar with London fashionable life. We have had life-histories, three volumes at a time, that have taken us into the very houses, told us of all the domestic quarrels, some already healed, some still pending. It is easy to imagine of whom the world was composed that crowded the concerts of the celebrated musician. The Pendennises were there, and the Newcomes, Jane Rochester with her blind husband, a young Lord St. Orville with one of the Great-Grand-Children of the Abbey, Mr. Thornton and Margaret Thornton, a number of semi-attached couples, Lady Lufton and her son, the De Joinvilles visiting the Osbornes, from France, Miss Dudleigh and Sarona, Alton Locke, on a visit home, Signor and Signora Mancini, sad-eyed Rachel Leslie with her young brother, a stately descendant of Sir Charles Grandison, the Royal Family, and all the nobility. When everybody went,—every one fortunate enough to get a ticket and a seat in the crowded hall,—it would be invidious to mention names. It was the fashion to go; and so everybody went who was in the fashion. Then of course the unfashionables went, that it might not be supposed they were of that class; and with these, all those who truly loved music were obliged to contend for a place. Fashion was on the side of music, till it got the audience fairly into the hall and in their seats; and then music had to struggle with fashion. It had to fix and melt the wandering eyes, to tug at the worldly and the stony heart. And here it was that Arnold's music won the victory. The ravishing bonnet of Madam This or That no longer distracted the attention of its envying admirers, or of its owner; the numerous flirtations that had been thought quite worth the price of the ticket, and of the crushed flounces, died away for a few moments; the dissatisfaction of the many who discovered themselves too late in inconspicuous seats was drowned in the deeper and sadder unrest that the music awakened. For the music spoke separately to each heart, roused up the secrets hidden there, fanned dying hopes or silent longings. It made the light-hearted lighter in heart, the light-minded heavy in soul. Where there was a glimpse of heaven, it opened the heavens wider; where there was already hell, it made the abysses gape deeper. For those few moments each soul communed with itself, and met with a shuddering there, or an exaltation, as the case might be.

After those few moments, outside life resumed its sway. Buzzing talk swept out the memory of the music. One song from an opera brought thought back to its usual level. Men and women looked at each other through their opera-glasses, and, bringing distant outside life close to them, fancied themselves in near communion with it. The intimacy of the opera-glass was warm enough to suit them,—so very near at one moment, comfortably distant at the next. It was an intimacy that could have no return, nor demanded it. One could study the smile on the lip of one of these neighbors, even the tear in her eye, with one's own face unmoved, an answer of sympathy impossible, not required. Nevertheless, the music had stirred, had excited; and the warmth it had awakened was often transferred to the man who had kindled it. The true lovers of music could not express their joy and were silent, while these others surrounded Arnold with their flatteries and adoration.

He was soon wearied of this.

"I am going to America, to a new world," he said to his friend; "there must be some variety there."

"Perhaps so," said Carl,—"something new, something that is neither man nor woman, since they cannot satisfy you. Still I fancy you will find nothing higher than men and women."

"A new land must develop men and women in a new way," answered Arnold.

"If you would only look at things in my microscopic way," said Carl, "and examine into one man or one woman, you would not need all this travelling. But I will go as far as New York with you."

At New York the name of the musician had already awakened the same excitement as in other places; the concert-room was crowded; there was the same rush for places; the prices paid for the tickets seemed here even more fabulous. Arnold was more of a lion than ever. His life was filled with receptions, dinners, and evening parties, or with parlor and evening concerts. His dreamy, poetic face, his distant, abstracted manner, proved as fascinating as his music.

Carl tired of the whirl, and the adoration, of which he had his share.

"I shall go back to Germany," he said. "I shall go to my Rosa, and leave you your world."

"I am tired of my world. I shall go to the Far West," said Arnold, when Carl left him.

One day he went to a matinée at one of the finest and most fashionable houses in the place. There were beautiful women elegantly dressed, very exquisite men walking up and down the magnificently furnished drawing-rooms. The air was subdued, the voices were low, the wit was quiet, the motion was full of repose, the repose breathed grace. Arnold seated himself at the Steinway, at the half-expressed request of the hostess, and partly from the suggestions of his own mood. He began with dreamy music; it was heavy with odors, at first, drugged with sense, then spiritualizing into strange, delicate fancies. Then came strength with a sonata of Beethoven's; then the strains died back again into a song singing without words.

4I use surface often in its geological significance, meaning earth-crust, and applied to sea-bottom as well as to dry land.
