Underneath the inner cloud-veil the atmosphere of Saturn appeared to them somewhat as the lower depths of the ocean would appear to a diver, granted that he was able to see for hundreds of miles about him. Its colour was a pale greenish yellow. The outside thermometers showed that the temperature was a hundred and seventy-five Fahrenheit. In fact, the interior of the _Astronef_ was getting uncomfortably like a Turkish bath, and Redgrave took the opportunity of at once freshening and cooling the air by releasing a little oxygen from the cylinders. From what they could see of the surface of Saturn it seemed to be a dead level, greyish brown in colour, and not divided into oceans and continents. In fact there were no signs whatever of water within range of their telescopes. There was nothing that looked like cities, or any human habitations, but the ground, as they got nearer to it, seemed to be covered with a very dense vegetable growth, not unlike gigantic forms of seaweed, and of somewhat the same colour. In fact, as Zaidie remarked, the surface of Saturn was not at all unlike what the floors of the ocean of the Earth might be if they were laid bare. It was evident that the life of this portion of Saturn was not what, for want of a more exact word, might be called terrestrial. Its inhabitants, however they were constituted, floated about in the depths of this semi-gaseous ocean as the denizens of earthly seas did in the terrestrial oceans. Already their telescopes enabled them to make out enormous moving shapes, black and grey-brown and pale red, swimming about, evidently by their own volition, rising and falling and often sinking down on to the gigantic vegetation which covered the surface, possibly for the purpose of feeding. But it was also evident that they resembled the inhabitants of earthly oceans in another respect, since it was easy to see that they preyed upon each other. "I don't like the look of those creatures at all," said Zaidie, when the _Astronef_ had come to a stop and was floating about ten miles above the surface. "They're altogether too uncanny. They look to me something like jelly-fish about the size of whales, only they have eyes and mouths. Did you ever see such awful-looking eyes, bigger than soup-plates and as bright as a cat's. I suppose that's because of the dim light. And the nasty wormy sort of way they swim, or fly, or whatever it is. Lenox, I don't know what the rest of Saturn may be like, but I certainly don't like this part. It's quite too creepy and unearthly for my taste. Look at the horrors fighting and eating each other. That's the only bit of earthly character they've got about them; the big ones eating the little ones. I hope they won't take the _Astronef_ for something nice to eat." "They'd find her a pretty tough morsel if they did," laughed Redgrave, "but still we may as well get some steering way on her in case of accident." CHAPTER XVIII
