"Not every week," said Charles Broadman, "but we will still hold them.

This all happened before, you know."

"I want to come however often they are," Sally insisted "How often will we hold them, dreamer, and we all near dead?" Harry asked. "You say that this has happened before, Broadman? Well then, didn't we all die with it before?"

"No. We lived an immeasurably long time with it before," Charles Broadman stated. "What, can you not read the signs in the soot yet, Harry?"

"Just how often would you suggest that we meet then, Charles?" Clement Flood asked with weary sarcasm.

"Oh, how about once every hundred years, gentlemen and Sally. Would that be too often?"

"Fool," Harry Baldachin wheezed and peered out from under his thickening orbital ridges.

"Idiot," Clement Flood growled from his thickening throat.

"Why, I think a hundred years from today would be perfect," Sally cried.

"That will be a wednesday, will it not?"

"That was fast," Broadman admired. "Yes, it will be a wednesday, Sally.

Do be here, Sally, and we will talk some more of these matters. Interesting things will have happened in the meanwhile. And you two gentlemen will be here?"

"No, don't refuse," Sally cut in. "You are so unimaginative about all this. Mr. Baldachin, say that you will dine with us here one hundred years from today if you are alive and well."

"By the emphyseman God that afflicts us, and me dying and gone, yes, I will be here one hundred years from today if I am alive and well," Harry Baldachin said angrily. "But I will not be alive this time next week."

"And you say it also, Mr. Flood," Sally insisted.

"Oh, stop putting fools' words in peoples' mouths, little girl. Let me die in my own phlegm."

"Say it, Mr. Flood," Sally insisted again, "say that you will dine with us all here one hundred years from this evening if you are alive and well."

"Oh, all right," Clement Flood mumbled as he bled from his rheumy eyes.

"Under those improbable conditions I will be here."

But only Sally and Charles Broadman had the quick wisdom to understand that the thing was possible.

Fog, smog, and grog, and the people perished. And the more stubborn ones took a longer time about perishing than the others. But a lethal mantle wrapped the whole globe now. It was poison utterly compounded, and no life could stand against it. There was no possibility of improvement, there was no hope of anything. It could only get worse. Something drastic had to happen.

And of course it got worse. And of course something drastic happened.

The carbon pollution on earth reached trigger mass. But it didn't work out quite as some had supposed that it might.

Lost Skies -- O'HanlonOh, for one thing, no rain, or almost no rain fell on the earth for that next hundred years. It was not missed. Moisture was the one thing that was in abounding plenty.

"But a mist rose from the earth and watered all the surface of the ground."

Rainless rain forests grew and grew. Ten million cubic miles of seawater rose to the new forming canopy and hung there in a covering world-cloud no more than twenty miles up. Naturally the sun and moon and stars were seen no more on the earth for that hundred years; and the light that did come down through the canopy seemed unnatural. But plants turned into giant plants and spread over the whole earth, gobbling the carbon dioxide with an almost audible gnashing.

So there was more land, now, and wetter land. There was a near equipoise of temperature everywhere under the canopy. The winds were all gathered up again into that old leather bag and they blew no more on the earth. Beneath the canopy it was warm and humid and stifling from pole to pole and to the utmost reaches of the earth.

It was a great change and everything felt it. Foot-long saurians slid out of their rocks that were warm and moist again: and gobbled and grew, and gobbled and grew, and gobbled and grew. Old buried fossil suns had been intruded into the earth air for a long time, and now the effect of their carbon and heat was made manifest. Six-foot-diameter turtles, having been ready to die, now postponed that event: and in another hundred years, in two hundred, they would be ten-foot-diameter turtles, thirteen-foot-diameter turtles.

The canopy, the new lowering copper-colored sky, shut out the direct sun and the remembered blue sky, and it shut out other things that had formerly trickled down: hard radiation, excessive ultraviolet rays and all the actinic rays, and triatomic oxygen. These things had been the carriers of the short and happy life, or the quick and early death; and these things were no longer carried down.

There was a thickening of bone and plate on all boned creatures everywhere, as growth continued for added years. There were new inhibitors and new stimulants; new bodies for old -- no, no -- older bodies for old. Certain teeth in certain beasts had always grown for all the beast life. Now the beast life was longer, and the saber-tooths appeared again.

It was murky under the new canopy, though. It took a long time to get used to it-and a long time was provided. It was a world filled with fogs, and foggy phrases.

'A very ancient and fish-like smell.'

'Just to keep her from the foggy foggy dew.'

'There were giants on the earth in those days.'

'When Enos was ninety years old, he became the father of Cainan. Enos lived eight hundred and fifteen years after the birth of Cainan, and had other sons and daughters.'

'Behold now Behemoth, which I have made with thee.'

'And beauty and length of days.'

'There Leviathan... stretched like a promontory sleeps or swims.

'I will restore to you the years that the locust has eaten.'

"A land where the light is as darkness," said Job.

"Poor Job," said Sally Strumpet.

"This is my sorrow, that the right hand of the Most High is changed,"

said the Psalmist.

"Poor Psalmist," said Sally Strumpet.

The world that was under the canopy of the lowering sky was very like a world that was under water. Everything was incomparably aged and giantized and slow. Bears grew great. Lizards lengthened. Human people broadened and grew in their bones, and lengthened in their years."I suppose that we are luckier than those who come before or after,"

Harry Baldachin said. "We had our youths, we had much of our proper lives, and then we had this."

This was a hundred years to a day (a wednesday, was it not?) since that last club dinner, and the four of them, Harry Baldachin, Clement Flood, Charles Broad-man, and Sally Strumpet were met once more in the Mountain Top Club. Two of them, it will be remembered, hadn't expected to be there.

"What I miss most in these last nine or ten decades is colors," Clement Flood mused. "Really, we haven't colors, not colors as we had when I was young. Too much of the sun is intercepted now. Such aviators as still go up (the blue-sky hobbyists and such) say that there are still true colors above the canopy, that very ordinary objects may be taken up there and examined, and that they will be in full color as in ancient times. I believe that the loss of full color was understood by earlier psychologists and myth makers. In my youth, in my pre-canopy youth, I made some studies of very ancient photography. It was in black and white and gray only, just as most dreams were then in black and white and gray only. It is strange that these two things nearly anticipated the present world: we are so poor in color that we nearly fall back to the old predictions. No person under a hundred years old, unless he has flown above the canopy, has ever seen real color. But I will remember it."

"I remember wind and storm," said Harry Baldachin, "and these cannot now be found in their real old form even by going above the canopy. I remember frost and snow, and these are very rare everywhere on earth now. I remember rain, that most inefficient thing ever -- but it's pleasant in memory."

"I remember lightning," said Charles Broadman, "and thunder. Ah, thunder."

"Well, it's more than made up for in amplitude," Clement smiled. "There is so much more of the earth that is land now, and all the land is gray and growing -- I had almost used the old phrase 'green and growing,' but the color green can be seen now only by those who ascend above the canopy. But the world is warm and moist from pole to pole now, and filled with giant plants and giant animals and giant food. The canopy above, and the greenhouse diffusion effect below, it makes all the world akin. And the oceans are so much more fertile now -- one can almost walk on the backs of the fish. There is such a lot more carbon in the carbon cycle than there used to be, such a lot more life on the earth. And more and more carbon is being put into the cycle every year.

"That's true," said Harry Baldachin. "That's about the only industrialism that is still being carried out, the only industrialism that is still needed: burning coal and petroleum to add carbon to the cycle, burning it by the tens of thousands of cubic miles. Certain catastrophes of the past had buried great amounts of this carbon, had taken it out of the cycle, and the world was so much poorer for it. It was as if the fruit of whole suns had been buried uselessly in the earth. Now, in the hundred years since the forming or the reforming of the canopy, and to a lesser extent during the two hundred years before its forming, these buried suns have been dug up and put to use again.

"The digging up of buried suns has caused all manner of mischief,"

Charles Broadman said.

"You are an old fogy, Charles," Clement Flood told him. "A hundred years of amplitude have made no change at all in you.

The hundred years had really made substantial changes in all of them.

They hadn't aged exactly, not in the old way of aging. They had gone on growing in a new, or a very old way. They had thickened in face and body. They had become more sturdy, more solid, more everlasting. Triatomic oxygen, that old killer, was dense in the world canopy, shutting out the other killers; but it was very rare at ground level, a perfect arrangement. There was no wind under the canopy, and things held their levels well. How long persons might live now could only be guessed. It might be up to a thousand years."And how is the -- ah -- younger generation?" Harry Baldachin asked.

"How are you, Sally? We have not seen you for a good round century."

"I am wonderful, and I thought you'd never ask. People take so much longer to get to the point now, you know. The most wonderful news is that I now test fertile. When I was seventeen I worried that I didn't test out. The new times had already affected me, I believe. But now my term has come around, and about time I'd say. I'm a hundred and seventeen and there are cases of girls no more than a hundred who are ready. I will marry this very week and will have sons and daughters. I will marry one of the last of the aviators who goes above the canopy. I myself have gone above the canopy and seen true colors and felt the thin wind."

"It's not a very wise thing to do," said Harry. "They are going to put a stop to flights above the canopy, I understand. They serve no purpose; and they are unsettling."

"Oh, but I want to be unsettled," Sally cried.

"You should be old enough not to want any such thing, Sally," Clement Flood advised. "We are given length of days now, and with them wisdom should come to us."

"Well, has wisdom come?" Charles Broadman asked reasonably. "No, not really. Only slowness has come to us."

"Yes, wisdom, we have it now," Harry Baldachin insisted. "We enter the age of true wisdom. Long wisdom. Slow wisdom."

"You are wrong, and unwise," Charles Broadman said out of his thickened and almost everlasting face. "There is not, there has never been any such name or thing as unqualified Wisdom. And there surely are not such things as Long Wisdom or Slow Wisdom."

"But there is a thing named Swift Wisdom," Sally stated with great eagerness.

"There was once, there is not now, we lost it," Charles Broadman said sadly.

"We almost come to disagreement," Baldachin pro-tested, "and that is not seemly for persons of the ample age. Ah well, we have lingered five hours over the walnuts and the wine, and perhaps it were the part of wisdom that we leave each other now. Shall we make these dinners a regular affair?"

"I want to," Sally said.

"Yes, I'd rather like to continue the meetings at regular intervals,"

Clement Flood agreed.

"Fine, fine," Charles Broadman murmured. "We will meet here again one hundred years from this evening."

3.

And some forget to leave or let And some forget to die: But may my right hand wither yet If I forget the sky.

Lost Skies -- O'Hanlon We are not so simple as to say that the Baluchitherium returned. The Baluchitherium was of an earlier age of the earth and flourished under an earlier canopy. Something that looked very like the Baluchitherium did appear, however. It was not even of the rhinoceros family. It was a horse grown giant and gangly. Horses of course, being artificial animals like dogs, are quite plastic and adaptable. A certain upper-lippiness quickly appeared when this new giant animal had turned into a giant leaf eater and sedge eater ("true"

grass had about disappeared: how could it compete with the richer and fuller plants that flourished under the canopy?); a certain spreading of the hoofs, a dividedness more of appearance than of fact, was apparent after this animal had become a swamp romper. Well, it was a giant horse and a mighty succulenthorse, but it looked like the Baluchitherium of old.

We are not so naive as to accept that the brontosaurus came back. No.

But there was a small flatfooted lizard that quickly became a large flatfooted lizard and came to look more and more like the brontosaurus. It came to look like this without changing anything except its size and its general attitude towards the world. Put a canopy over any creature and it will look different without much intrinsic change.

We surely are not gullible enough to believe that the crinoid plants returned to the ponds and the slack water pools. Well, but certain conventional long-stemmed water plants had come to look and behave very like the crinoids.

All creatures and plants had made their peace with the canopy, or they had perished. The canopy, in its two hundredth year, was a going thing; and the blue-sky days had ended forever.

There was still vestigial organic nostalgia for the blue-sky days, however. Most land animals still possessed eyes that would have been able to see full colors if there were such colors to be seen; man himself still possessed such eyes. Most food browsers still possessed enough crown to their teeth to have grazed grass if such an inefficient thing as grass had remained.

Many human minds would still have been able to master the mathematics of stellar movements and positions, if ease and the disappearance of the stellar content had not robbed them of the inclination and opportunity for such things.

(There was, up to about two hundred years ago, a rather cranky pseudo-science named astronomy.) There were other vestiges that hung like words in the fog and rank dew of the world.

'And the name of the star is called Wormwood.'

'In the brightness of the saints, before the day-star."

'It was the star-eater who came, and then the sky-eater.'

"And the stars are not clear in his sight," said Job.

"Poor Job," said Sally.

The second hundred years had gone by, and the diners had met at Mountain Top Club again. And an extra diner was with them.

"Poor Sally," said Harry Baldachin. "You are still a giddy child, and you have already had sons and daughters. But you should not have brought your husband to this dinner without making arrangements. You could have proposed it this time, and had him here the next time. After all, it would only be a hundred years."

We are not so soft-headed as to say that the Neanderthal Men had returned. But the diners at Mountain Top Club, with that thickening of their faces and bones and bodies that only age will bring, had come to look very like Neanderthals -- even Sally a little.

"But I wanted him here this time," Sally said. "Who knows what may happen in a hundred years?"
