"They're mountains of crystal!"

"Mountains of crystal!" we echoed.

"Nothing else in the world, and I am ashamed not to have foreseen the thing. It's plain enough when you come to think about it. Remember that Venus being a world lying half in the daylight and half in the night, is necessarily as hot on one side as it is cold on the other. All of the clouds and floating vapors are on the day side, where the sunbeams act. The heated air charged with moisture rises over the sunward hemisphere, and flows off above, on all sides, toward the night side, while from the latter cold air flows in beneath to take its place. Along the junction of the two hemispheres the clouds and moisture are condensed by the intense cold, and fall in ceaseless snowstorms. This snow descending for ages has piled up in mountainous masses whose height may be increased in some places by real mountain ranges buried beneath. The atmospheric moisture cannot pass very far into the night hemisphere without being condensed, and so it is all arrested within a ring, or band, extending completely around the planet, and marking the division between perpetual day and perpetual night. The appearance of gigantic flames is produced by the sunbeams striking these mountains of ice and snow from behind and breaking into prismatic fire."

We listened to this explanation, so simple and yet so wonderful, with mingled feelings of astonishment and admiration. And then we turned again to regard the phenomenon, which now, with our nearer approach, had become splendid and awful beyond description.

In a few minutes Edmund addressed us again. "I foresee now," he said, "considerable trouble for us. There has been a warning of that, too, if I had but heeded it. I've noticed for some time that a wind, getting gradually stronger, has been following us, sometimes dying out and then coming on again stronger than before. It is likely that this wind gets to be a perfect hurricane in the neighborhood of those strange mountains. It is the back suction, caused, as I have already told you, by the rising of the heated air on the sunny side of the planet. It may play the deuce with us when we get into the midst of it. I shall have to be cautious."

He immediately reduced the speed to not more than ten miles an hour, and at once we noticed the wind of which he had spoken. It came now in great gusts from behind, rapidly increasing in frequency and fury. Soon it was strong enough to drive the sleds without any pull upon the cable, and sometimes they were forced directly under the car, and even ahead of it, the natives clinging to one another in the utmost terror. Edmund managed to govern the motions of the car for a time, holding it back against the storm, but as he confessed, this was a contingency he had made no provision for, and eventually we became almost as helpless as a ship in a typhoon.

"Of course I could cut loose from the sleds and run right out of this," said Edmund, "but that would never do. I've taken them into my service and I'm bound to look out for them. If there was room for them in the car it would be all right. Let's see. Yes! I've got it. I'll fetch up the sleds and fasten them underneath the car, like baskets to a balloon, and so carry the whole thing. There's plenty of power; it's only room that's wanting."

No sooner said than done with Edmund. By this time we were getting into the ice, huge hills of which surrounded us. Edmund dropped the car in the lee of one of these strange hummocks. Here the force of the wind was broken, and the sky directly over us was free from clouds, but a short distance ahead we could see them whirling and tumbling in mighty masses of tumultuous vapor. Lashing the two sleds together we attached them about ten feet below the bottom of the car. Then the natives, who had been unbound, and had stood looking on in utter bewilderment, were securely fastened on the sleds. We entered the car and the power was turned on.

"We'll rise straight up," said Edmund, "and as soon as we are out of the wind current we will sail over the mountains and come down on the other side as nice as you please. Strange that I didn't think of carrying the sleds in this way to begin with."

It was a beautiful program that Edmund had outlined, and we had complete confidence in our leader's ability to carry it through; but it didn't work as expected. Even his genius had met its match this time.
