"I ought to have had a photograph of you like that!" he laughed. "I wonder what they'd think of it at home?"

"If you had taken one I should certainly have broken the negative. The very idea—a photograph of me standing on nothing! Besides, they'd never believe it on Earth."

"We might have got old Andrew to make an affidavit as to the true circumstances," he began.

"Don't talk nonsense, Lenox! Look! there's something much more interesting. There's Saturn at last. Now I wonder if we shall find any sort of life there—and shall we be able to breathe the air?"

"I hardly think so," he said, as the Astronef dropped slowly through the thin cloud-veil. "You know spectrum analysis has proved that there is a gas in Saturn's atmosphere which we know nothing about, and, however good it may be for the Saturnians, it's not very likely that it would agree with us, so I think we'd better be content with our own. Besides, the atmosphere is so enormously dense that even if we could breathe it it might squash us up. You see we're only accustomed to fifteen pounds on the square inch, and it may be hundreds of pounds here."

"Well," said Zaidie, "I haven't got any particular desire to be flattened out, or squeezed dry like an orange. It's not at all a nice idea, is it? But look, Lenox," she went on, pointing downwards, "surely this isn't air at all, or at least it's something between air and water. Aren't those things swimming about in it—something like fish in the sea? They can't be clouds, and they aren't either fish or birds. They don't fly or float. Well, this is certainly more wonderful than anything else we've seen, though it doesn't look very pleasant. They're not nice-looking, are they? I wonder if they are at all dangerous!"

While she was saying this Zaidie had gone to her telescope, and was sweeping the surface of Saturn, which was now about a hundred miles distant. Her husband was doing the same. In fact, for the time being they were all eyes, for they were looking on a stranger sight than man or woman had ever seen before.

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.
