III
THE FIRST VENUSIAN
When the sky-car was within a thousand miles of the surface, Smith adjusted the currents so that the floor was directed downward. The four changed from the window to the deadlight, and watched the approaching disk with every bit of the excitement and interest they had felt when nearing Mercury.
The doctor had warned them that the heavy atmosphere which Venus was known to possess would prevent seeing as clearly as in the case of the smaller planet. All were much disappointed, however, to find that they were still unable to make out a single definite detail. The great half-shining, half-black world showed nothing but that vaguely streaked, ice-like haze.
There was something very queer about it all. "Strange that we should see no movement in those clouds," mused the doctor aloud. "That is, if they really are clouds."
Van Emmon already doubted it. "Just what I was thinking. There ought to be terrific winds; yet, so far as I have seen, there's been nothing doing anywhere on the surface since we first began to observe it."
After a while the doctor put away his binoculars and rubbed his eyes. "We might as well descend faster, Smith. Can't see a thing from here."
Unhindered by air to impede its progress the sky-car had been hurtling through space at cometary speed. Now, however, Smith added the power of the apparatus to the pull of the planet, so that the disk began to rush toward them at a truly alarming rate. After a few seconds of it Billie found herself unconsciously moving to the side of the geologist.
He looked down at her, understood, and flushed with pleasure. "There's no danger," he confidently assured her, with the result that, her courage fortified, the girl moved back to her place again. Van Emmon inwardly kicked himself.
So deceptive was that peculiar fogginess Smith throttled their descent as soon as they had reached the point where the planet's appearance changed from round to flat. They were headed for the line which marked the boundary of the shadow. This gray "twilight zone" was three or four hundred miles in width; on the right of it—to the east—the dazzling surface of that sunlit vapor contrasted sharply with the all but black mistiness of the starward side. Clearly the zone ought to be temperate enough.
