Time and Change Part 6

Something happened between each two layers. What?

Though in remote geological ages the earth-building and earth-shaping forces were undoubtedly more active than they are now, and periods of deformation and upheaval were more frequent, yet had we lived in any of those periods we should probably have found the course of nature, certainly when measured by human generations, as even and tranquil as we find it to-day. The great movements are so slow and gentle, for the most part, that we should not have been aware of them had we been on the spot. Once in a million or a half-million years there may have been terrific earthquakes and volcanic eruptions, such as seem to have taken place in Tertiary time, and at the end of the Palaeozoic period. Yet the vast stretches of time between were evidently times of tranquillity.

It is probable that the great glacial winter of Pleistocene times came on as gradually as our own winter, or through a long period of slowly falling temperature, and as it seems to have been many hundred thousand times as long, this preceding period, or great fall, was probably equally long--so long that the whole of recorded human history would form but a small fraction of it. It may easily be, I think, that we are now living in the spring of the great cycle of geologic seasons. The great ice-sheet has withdrawn into the Far North like s...o...b..nks that linger in our wood in late spring, where it still covers Greenland as it once covered this country. When the season of summer is reached, some hundreds of thousands of years hence, it may be that tropical life, both animal and vegetable, will again flourish on the sh.o.r.es of the Arctic Ocean, as it did in Tertiary times. And all this change will come about so quietly and so slowly that n.o.body will suspect it.

That the crust of the earth is becoming more and more stable seems a natural conclusion, but that all folding and shearing and disruption of the strata are at an end, is a conclusion we cannot reach in the face of the theory that the earth is shrinking as it cools.

The earth cools and contracts with almost infinite slowness, and the great crustal changes that take place go on, for the most part, so quietly and gently that we should not suspect them were we present on the spot, and long generations would not suspect them. Elevations have taken place across the beds of rivers without deflecting the course of the river; the process was so slow that the river sawed down through the rock as fast as it came up. Nearly all the great cosmic and terrestrial changes and revolutions are veiled from us by this immeasurable lapse of time.

Any prediction about the permanence of the land as we know it, or as the race has known it, or of our immunity from earthquakes or volcanic eruptions, or of a change of climate, or of any cosmic catastrophe, based on human experience, is vain and worthless. What is or has been in man's time is no criterion as to what will be in G.o.d's time. The periods of great upheaval and deformation in the earth's crust appear to be separated by millions of years. Away back in pre-Cambrian times, there appear to have been immense periods during which the peace and repose of the globe were as profound as in our own time. Then at the end of Palaeozoic time--how many millions of years is only conjectural--the truce of aeons was broken, and the dogs of war let loose; it was a period of revolution which resulted in the making of one of our greatest mountain-systems, the Appalachian, and in an unprecedented extinction of species. Later eras have witnessed similar revolutions. Why may they not come again? The shrinking of the cooling globe must still go on, and this shrinking must give rise to surface disturbances and dislocations, maybe in the uplift of new mountain-ranges from the sea-bottom, now undreamed of, and in volcanic eruptions as great as any in the past. Such a shrinkage and eruption made the Hawaiian Islands, probably in Tertiary times; such a shrinkage may make other islands and other continents before another period of equal time has elapsed.

Of course the periods and eras into which the geologists divide geologic time are as arbitrary as the months and seasons into which we divide our year, and they fade out into each other in much the same way; but they are really as marked as our seasonal divisions.

Not in their climates--for the climate of the globe seems to have been uniformly warm from pole to pole, without climatic zones, throughout the vast stretch of Palaeozoic and Mesozoic times--but in the succession of animal and vegetable life which they show. The rocks are the cemeteries of the different forms of life that have appeared upon the globe, and here the geologist reads their succession in time, and a.s.signs them to his geologic horizons accordingly. The same or allied forms appeared upon all parts of the earth at approximately the same time, so that he can trace his different formations around the world by the fossils they hold. Each period had its dominant forms. The Silurian was the great age of trilobites; the Devonian, the age of fishes; Mesozoic times swarm with the gigantic reptiles; and in Tertiary times the mammals are dominant. Each period and era has its root in that which preceded it. There were rude, half-defined fishes in the Silurian, and probably the beginning of amphibians in the Devonian, and some small mammalian forms in the Mesozoic time, and doubtless rude studies of the genus h.o.m.o in Tertiary times. Nature works up her higher forms Jike a human inventor from rude beginnings. Her first models barely suggest her later achievements.

In the vegetable world it has been the same; from the first simple algae in the Cambrian seas up to the forests of our own times, the gradation is easily traced. Step by step has vegetable life mounted.

The great majority of the plants and animals of one period fail to pa.s.s over into the next, just as our spring flowers fail to pa.s.s over into summer, and our summer flowers into fall. But the law of evolution is at work, and life always rises on stepping-stones of its dead self to higher things.

HOLIDAYS IN HAWAII

I

On the edge of the world my islands lie," sings Mrs. Frear in her little lyric on the Hawaiian Islands.

"On the edge of the world my islands lie, Under the sun-steeped sky; And their waving palms Are bounteous alms To the soul-spent pa.s.ser-by.

"On the edge of the world my islands sleep In a slumber soft and deep.

What should they know Of a world of woe, And myriad men that weep?"

On the rim of the world my fancy seemed to see them that May day when we went aboard the huge Pacific steams.h.i.+p in San Francisco Harbor, and she pointed her prow westward toward the vast wilderness of the Pacific--on the edge of the world, looking out and down across the vast water toward Asia and Australia. I wondered if the great iron s.h.i.+p could find them, and if we should realize or visualize the geography or the astronomy when we got there, and see ourselves on the huge rotundity of the globe not far above her equatorial girdle.

Yes, on the rim of the world they lie to the traveler steaming toward them, and on the rim of the world they lie in his memory after his return, basking there in that tropical sunlight, forever fanned by those cooling trade winds, and encompa.s.sed by that morning-glory sea. With my mind's eye I behold them rising from that enormous abyss of the Pacific, fire-born and rain-carved, vast volcanic mountains miles deep under the sea, and in some cases miles high above it, clothed with verdure and teeming with life, the scene of long-gone cosmic strife and destruction, now the abode of rural and civic peace and plenty.

The Pacific treated me so much better than the Atlantic ever had that I am probably inclined to overestimate everything I saw on the voyage. It was the first trip at sea that ever gave me any pleasure.

The huge vessels are in themselves a great comfort, and in the placid waters and the sliding down the rotund side of the great globe under warmer and warmer skies one gains a very agreeable experience. The first day's run must have carried us out and over that huge Pacific abyss, the Tuscarora Deep, where there were nearly four miles of water under us. Some of our aeroplanes have gone up half that distance and disappeared from sight. I fancy that our s.h.i.+p, more than six hundred feet long, would have appeared a very small object, floating across this briny firmament, could one have looked up at it from the bottom of that sea.

The Hawaiian Islands rise from the border of that vast deep, and one can fancy how that huge pot must have boiled back in Tertiary times, when the red-hot lava of which they are mainly built up was poured from the interior of the globe.

Softer and more balmy grew the air every day, more and more placid and richly tinted grew the sea, till, on the morning of the sixth day, we saw ahead of us, low on the horizon, the dim outlines of the mountains of Molokai. The island of Oahu, upon which Honolulu is situated, was soon in sight. It was not long before we saw Diamond Head, a vast crater bowl, eight hundred feet high on its ocean side, and half a mile across, sitting there upon the sh.o.r.e like some huge, strange work of man's hand, running back through the hills with a level rim, and seaward with a sloping base, brown and ribbed, and in every way unique and striking.

We were approaching a land the child of tropic seas and volcanic lava, and many of the features were new and strange to us. The mountains looked familiar in outline, but the colors of the landscape, the soft lilacs, greens, and browns, and the whole atmosphere of the scene, were unlike anything we had ever before seen. And Diamond Head, what a feature it was! Had it only had a head, one could easily have seen in it a suggestion of a couchant lion, bony, huge, and tawny, looking seaward, and guarding the harbor of Honolulu which lies just behind it. Into this harbor, in the soft morning air, our s.h.i.+p soon found its way, and the monotony of the vast, unpeopled sea was quickly succeeded by human scenes of the most varied and animated character, not the least novel of which were the swarms of half-amphibious native boys who surrounded the vessel as she lay at the wharf, and with brown, upturned faces and beckoning hands tempted the pa.s.sengers to toss dimes into the water.

As the coins struck the surface they would dive with the ease and quickness of seals, and seize the silver apparently before it had gone a yard toward the bottom. Holding the coins up to view between the thumb and finger, they would slip them into their mouths and solicit more.

On sh.o.r.e we were greeted with the music of the Royal Hawaiian Band, and a motley crowd of Hawaiians, j.a.panese, Chinese, Portuguese, and Americans, bearing colored leis, or wreaths of flowers, which they waved at friends on board, and with which they bedecked them as soon as they came off the gangplank. It was a Babel of tongues in which the strange, vowel-choked language of the Hawaiians was conspicuous.

Honolulu is a beautiful city, clean, bright, well ordered, and well appointed,--electric lights, good streets, electric cars, fine hotels and clubs, excellent fire protection, mountain water, libraries, parks, handsome buildings, attractive homes,--in fact, all that we boast of in our home cities. Embosomed in palms, with mangoes, and other tropical trees, with a profusion of gorgeously colored vines and hedges, with s.p.a.cious, well-kept grounds about the large and comfortable houses in the residential portion--these features, with the ready hospitality of the people, made our hearts warm towards it at once.

Volcanic heights on all the land side look down upon the city. Mount Tantalus, rising four thousand feet above the sea, is just back of it, with its long slopes of volcanic ash and sand now clothed by forests and fertile fields, and a huge ancient crater called the Punch Bowl, born probably on the selfsame day, the geologists think, as Diamond Head, dominates the city in the immediate foreground. If the Punch Bowl were again to overflow with the fiery liquid, the city would soon go up in smoke. But its bowl-like interior is now covered with gra.s.s and trees, and presents a scene of the most peaceful, rural character.

The Orient and the Occident meet in Honolulu. There Asia and America join hands. The main features of the city are decidedly American, but the people seen upon the street and at work indoors and out are more than half Oriental. The native population cuts only a small figure. The real workers--carpenters, masons, field hands, and house servants--are mostly j.a.panese. Virtually all the work of the immense sugar plantations is done by the little brown men and women, while China supplies some of the merchants in the city and the sailors and stewards on the ocean steamers. What admirable servants the Chinese make, so respectful, so prompt, so silent, so quick to comprehend! The j.a.panese house servants on the islands also give efficient and gracious service.

I had gone to Honolulu reluctantly, but tarried there joyfully. The fine climate, with its even temperature of about eighty degrees Fahrenheit, and with all that is enervating or oppressive in that degree of heat winnowed out of it by the ceaseless trade winds; the almost unbroken suns.h.i.+ne, perfumed now and then by a sprinkle of sunlit rain from the mountains; the wonderful sea laving the sh.o.r.es on the one hand and the cool, cloud-capped, and rain-drenched heights within easy reach on the other; the green, cozy valleys; the broad sweep of plain; the new, strange nature on every side; the novel and delicious fruits; the pepsin-charged papaya, or tree melon, which tickles the palate while it heals and renews the whole digestive system; the mangoes (oh, the mangoes!); the cordiality of the people; the inviting bungalows; the clean streets; the good service everywhere--all made me feel how mistaken was my reluctance.

Most of the Americans one meets there are descendants of the missionaries who went out from New England and New York early in the last century, and one feels at home with them at once. Many of the residents there have been educated in the States. The Governor, Mr.

Frear, is a graduate of Yale; his wife is a graduate of Wellesley.

One day a charming Southern woman, president of the College Club, invited us to meet the college women of the city. The gathering took place under the trees upon the lawn of one of the older homesteads.

There were forty college women present, many of them teachers, from Va.s.sar, Wellesley, Smith, Bryn Mawr, and Barnard. Among them were two girls who had visited me at my cabin, "Slabsides," while they were at Va.s.sar.

Wide as is the world, the traveler is pretty sure to strike threads of relation with his home country wherever he goes. I made the acquaintance in Honolulu of a man from my own county; another, who showed us great kindness, was from an adjoining county; while one day upon the street I was called by name by a man whom I had known as a boy in the town where I now live.

One Sat.u.r.day a walking-club, largely made up of men and women teachers, whose native Hawaiian name meant "Walkers in Unfrequented Places," asked us to join them in a walk up Palola Valley to the site of an extinct crater well up in the mountains. These walkers in unfrequented places proved to be real walkers, and gave us all and more than we had bargained for--more mud and wet and slippery trails through clinging vines and rank lantana scrub than was good for our shoes and garments or for the bodies inside them. It was a long pull of many miles, at first up the valley over a fair highway, then into the woods on the mountain-side along a trail that was muddy and slippery from the recent showers, and most of the time was buried out of sight beneath the high, coa.r.s.e stag-horn fern and a thick growth of lantana that met above it as high as our shoulders. A more discouraging mountain climb I never undertook. The vegetation was all novel, but it had that barbaric rankness of all tropical woods, with nothing of the sylvan sweetness and simplicity of our home woods. There were no fine, towering trees, but low, gnarled, and tortuous ones, which, with their hanging vines, like the broken ropes of a s.h.i.+p's rigging, and their parasitic growths, presented a riotous, disheveled appearance.

Nature in the tropics, left to herself, is harsh, aggressive, savage; looks as though she wanted to hang you with her dangling ropes, or impale you on her thorns, or engulf you in her ranks of gigantic ferns. Her mood is never as placid and sane as in the North. There is a tree in the Hawaiian woods that suggests a tree gone mad. It is called the hau-tree. It lies down, squirms, and wriggles all over the ground like a wounded snake; it gets up, and then takes to earth again. Now it wants to be a vine, now it wants to be a tree. It throws somersaults, it makes itself into loops and rings, it rolls, it reaches, it doubles upon itself. Altogether it is the craziest vegetable growth I ever saw. Where you can get it up off the ground and let it perform its antics on a broad skeleton framework, it makes a cover that no sunbeam can penetrate, and forms a living roof to the most charming verandas--or lanais, as they are called in the islands--that one can wish to see.

But I saw and heard one thing on this walk that struck a different note: it was one of the native birds, the Oahu thrush. The moment I heard it I was reminded of our brown thrasher, though the song, or whistle, was much finer and richer in tone than that of our bird.

The glimpse I got of the bird showed it to be of about the size and shape of our thrasher, but much brighter in color. It seems as though the two species must have had a common origin some time, somewhere. I was attracted by no other native bird on this walk. In the valley below we had seen and heard the Chinese workmen going about their rice-fields making strange sounds to drive away the rice-birds, a small, brown species that has been introduced from India.

When we reached the mountain-top, we found it enveloped in fog and mist, and the scene was cold and cheerless. We looked down through a screen of foliage into a deep valley that seemed almost beneath us, and which is supposed to have been an ancient crater. There, on the brink, the walkers had a rude cabin, where we ate our lunch beside a fire and tried to dry our bedraggled garments.

From this point some of the party continued their walk, looking for more unfrequented places, but some of us had longings the other way, and retraced our steps toward the sunlight and the drier winds we had left. We reached town footsore and bedraggled, and the little j.a.panese who cleaned and pressed my suit of clothes, and made them look as good as new for seventy-five cents, well earned his money.

The walk of eight or ten miles which we took two weeks later with Governor Frear and his wife, up the new Castle trail to the mountain-top behind Tantalus, had some features in common with the first walk,--the increasing mist and coolness as we entered the mountains, the dripping bushes, and the slippery paths,--but we got finer views, and found a better-kept trail. Our walk ended on the top of a narrow ridge of the mountain, where we ate our lunch in a cold, driving mist and were a bit uncomfortable. I was interested in the character of the ridge upon which we sat. It was not more than six feet wide, a screen of volcanic rock worn almost to an edge, and separated two valleys six or seven hundred feet deep. The Governor said he could take me where the dividing ridge between the two valleys was so narrow that one could literally sit astride of it, so that one leg would point to one valley and the other to the other.

This is a feature of a new country geologically; the rains and other agents of erosion have whittled the mountains to sharp edges, but have not yet rounded or leveled them.

The northeast trade winds which blow upon these islands nine months in the year bring a burden of moisture from the Pacific which is condensed into rain and mist by the mountains, and which, with the rank vegetation that it fosters, carves them and sharpens them like a great grindstone revolving against their sides. At a place called the Pali--and at the Needles, on the island of Maui--it has worn through the mountain-chain and made deep and very picturesque gorges where, in the case of the Pali, the wind is so strong and steady that you can almost lie down upon it.

It was near the Pali that I saw what I had never seen or heard of before--a waterfall reversed, going up instead of down. It suggested Stockton's story of negative gravity. A small brook comes down off the mountain and attempts to make the leap down a high precipice; but the winds catch it and carry it straight up in the air like smoke. It is translated; it becomes a mere wraith hovering above the beetling crag. Night and day this goes on, the wind s.n.a.t.c.hing from the mountains in this summary way the water it has brought them.

On the walk with the Governor we made the acquaintance of some of the land sh.e.l.ls for which these islands are famous--pretty, pearl-like little whorls living on the largest trees, and about the size of a chipping sparrow's egg, with pointed ends, variously colored. There are more than two hundred species on the different islands, I think, each valley having varieties peculiar to itself, showing what a factor isolation is in the evolution of new species.

The Governor and his wife, and a young man who had specialized in conchology, plucked them from nearly every bush and tree; but my eye, being untrained in this kind of work, was very slow in finding them.

Coming down from these Hawaiian mountains is like coming out of a dripping tent of clouds into the clear, warm suns.h.i.+ne. The change is most delightful. Your clothing dries very quickly, and chilliness gives place to genial warmth. And the prospects that open before you, the glimpses down into these deep, yellow-green, crater-like valleys, checkered with neat little Chinese farms, the panorama of the city and the sea unrolling as you come down, and always Diamond Head standing guard there to the east--how the vision of it all lingers in the memory!

In climbing the heights, it was always a surprise to me to see the Pacific rise up as I rose, till it stood up like a great blue wall there against the horizon. A level plain unrolls in the same way as we mount above it, but it does not produce the same illusion of rising up like a wall or a mountain-range; the blue, facile water cheats the eye.

One of the novel pleasures in which most travelers indulge while in Honolulu is surf-riding at Waikiki, near Diamond Head. The sea, with a floor of lava and coral, is here shallow for a long distance out, and the surf comes in at intervals like a line of steeds cantering over a plain. We went out in our bathing-suits in a long, heavy dugout, with a l.u.s.ty native oarsman in each end. When several hundred yards from sh.o.r.e, we saw, on looking seaward, the long, s.h.i.+ning billows coming, whereupon our oarsmen headed the canoe toward sh.o.r.e, and plied their paddles with utmost vigor, uttering simultaneously a curious, excited cry. In a moment the breaker caught us and, in some way holding us on its crest, shot us toward the sh.o.r.e like an arrow. The sensation is novel and thrilling. The foam flies; the waters leap about you. You are coasting on the sea, and you shout with delight and pray for the sensation to continue.

But it is quickly over. The hurrying breaker slips from under you, and leaves you in the trough, while it goes foaming on the sh.o.r.e.

Then you turn about and row out from the sh.o.r.e again, and wait for another chance to be shot toward the land on the foaming crest of a great Pacific wave.
