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.
