CHAPTER I.
SATURN.
Landing on a place about ten degrees north of the equator,so that they might obtain a good view of the great rings--since ONthe line only the thin edge would be visible--they opened a port-hole with the same caution they had exercised on Jupiter.
Again there was a rush of air,showing that the pressure without was greater than that within;but on this occasion the barometer stopped at thirty-eight,from which they calculated that the pressure was nineteen pounds to the square inch on their bodies,instead of fifteen as at sea-level on earth.This difference was so slight that they scarcely felt it.They also discarded the apergetic outfits that had been so useful on Jupiter,as unnecessary here.The air was an icy blast,and though they quickly closed the opening,the interior of the Callisto was considerably chilled.
"We shall want our winter clothes,"said Bearwarden;"it might be more comfortable for us exactly on the equator,though the scene at night will be far finer here,if we can stand the climate.
Doubtless it will also be warmer soon,for the sun has but just risen.""I suspect this is merely one of the cold waves that rush towards the equator at this season,which corresponds to about the 10th of our September,"replied Cortlandt."The poles of Saturn must be intensely cold during its long winter of fourteen and three quarter years,for,the axis being inclined twenty-seven degrees from the perpendicular of its orbit,the pole turned from the sun is more shut off from its heat than ours,and in addition to this the mean distance--more than eight hundred and eighty million miles--is very great.Since the chemical composition of the air we have inhaled has not troubled our lungs,it is fair to suppose we shall have no difficulty in breathing."Having dressed themselves more warmly,and seen by a thermometer they had placed outside that the temperature was thirty-eight degrees Fahrenheit,which had seemed very cold compared with the warmth inside the Callisto,they again opened the port-hole,this time leaving it open longer.What they had felt before was evidently merely a sudden gust,for the air was now comparatively calm.
Finding that the doctor's prediction as to the suitability of the air to their lungs was correct,they ventured out,closing the door as they went.
Expecting,as on Jupiter,to find principally vertebrates of the reptile and bird order,they carried guns and cartridges loaded with buckshot and No.1,trusting for solid-ball projectiles to their revolvers,which they shoved into their belts.They also took test-tubes for experiments on the Saturnian bacilli.
Hanging a bucket under the pipe leading from the roof,to catch any rain that might fall--for they remembered the scarcity of drinking-water on Jupiter--they set out in a southwesterly direction.
Walking along,they noticed on all sides tall lilies immaculately pure in their whiteness,and mushrooms and toadstools nearly a foot high,the former having a delicious flavour and extreme freshness,as though only an hour old.They had seen no animal life,or even sign of it,and were wondering at its dearth,when suddenly two large white birds rose directly in front of them.
Like thought,Bearwarden and Ayrault had their guns up,snapping the thumb-pieces over "safe"and pulling the triggers almost simultaneously.Bearwarden,having double buckshot,killed his bird at the first fire;but Ayrault,having only No.1,had to give his the second barrel,almost all damage in both cases being in the head.On coming close to their victims they found them to measure twelve feet from tip to tip,and to have a tremendous thickness of feathers and down.
"From the looks of these beauties,"said Bearwarden,"I should say they probably inhabited a pretty cold place.""They are doubtless northern birds,"said Cortlandt,"that have just come south.It is easy to believe that the depth to which the temperature may fall in the upper air of this planet must be something startling."As they turned from the cranes,to which species the birds seemed to belong,they became mute with astonishment.Every mushroom had disappeared,but the toadstools still remained.
"Is it possible we did not see them?"gasped Ayrault.
"We must inadvertently have walked some distance since we saw them,"said Cortlandt.
"They were what I looked forward to for lunch,"exclaimed Bearwarden.
They were greatly perplexed.The mushrooms were all about them when they shot the birds,which still lay where they had fallen.
"We must be very absent-minded,"said the doctor,"or perchance our brains are affected by the air.We must analyze it to see if it contains our own proportion of oxygen and nitrogen.There was a good deal of carbonic-acid gas on Jupiter,but that would hardly confuse our senses.The strange thing is,that we all seem to have been impressed the same way."Concluding that they must have been mistaken,they continued on their journey.
All about they heard a curious humming,as that of bees,or like the murmuring of prayers in a resonant cathedral.Thinking it was the wind in the great trees that grew singly around them,they paid no attention to it until,emerging on an open plain and finding that the sound continued,they stopped.
"Now,"said Bearwarden,"this is more curious than anything we found on Jupiter.Here we have an incessant and rather pleasant sound,with no visible cause.""It may possibly be some peculiarity of the grass,"replied Cortlandt,"though,should it continue when we reach sandy or bare soil,I shall believe we need a dose of quinine.""I FEEL perfectly well,"said Ayrault;"how is it with you?"Each finding that he was in a normal state,they proceeded,determined,if possible,to discover the source from which the sounds came.Suddenly Bearwarden raised his gun to bring down a long-beaked hawk;but the bird flew off,and he did not shoot.
