"Of course we shall escape," he replied cheerfully. "I give you my word for it, but do not ask me for any particulars yet. The exact means I have not yet found, but find them I will. We may have to stay where we are for a considerable time, and our companions must be made comfortable. Even under their furry skins they'll suffer from this kind of weather."

Following his directions we took a lot of extra furs from the car, and constructed a kind of tent, under which the natives could huddle on the sleds. There being but little wind in the valley, this was not so difficult an undertaking as it may seem. And the poor fellows were very glad of the shelter, for some of them were shivering, since, not knowing what to do, they were less active than ourselves. No sooner were they housed than they fell to eating ravenously. Both the car and the sleds had been abundantly provisioned, so that there was no immediate fear of a famine among us.

Inside the car we soon had things organized very much as they were during our voyage from the earth. We read, talked, and smoked to our hearts' content, almost forgetting the icy mountains that tottered over us, and the howling tempest which, with hardly an intermission, tore through the cloud-choked air a thousand or two thousand feet above our heads. We talked of our adventure with the meteors, which seemed an event of long ago, and then we talked of home—home twenty-six million miles away! In fact, it may have been thirty millions by this time, for Edmund had told us that Venus, having passed conjunction while we were at the caverns, was now receding from the earth.

But while we thus strove to kill the time and banish thoughts of our actual situation, Edmund sat apart much of the time absorbed in thought, and we respected his privacy, knowing that our only chance of escape lay in him. One day (I speak always of "days," because we religiously counted the passage of time by our clock) he issued alone from the car and was absent a long time, so that we began to be concerned, and, going outside looked everywhere for signs of him. At length, to our infinite relief, he appeared stumbling and crawling along the foot of an icy mountain. As he drew nearer we saw that he was smiling, and as soon as he was within easy earshot he called out:

"It's all right. I've found the solution."

Then upon joining us he continued:

"We'll get out all right, but we shall have to be patient for a while longer."

"What is it?" we asked eagerly. "What have you found out?"

"Peter," he said, turning to me, "you know what libration means; well, it's libration that is going to save us. As Venus travels round the sun she turns just once on her axis in making a complete circuit, the consequence being, as you already know, that she has one side on which the sun never rises while the other half is in perpetual daylight. But, since her orbit is not a perfect circle, she travels a little faster than the average during about half of her year and a little slower during the other half, but, at the same time, her steady rotation on her axis never varies. This produces the phenomenon that is called libration, the result of which is that, along the border between the day and night hemispheres there is a narrow strip where the sun rises and sets once in each of her years, which are about two hundred and twenty-five of our days in length. Within this strip the sun shines continuously for about sixteen weeks, gradually rising during eight weeks and sinking during the following eight. Then, during the next sixteen weeks, the strip lies in unceasing night.

"Now the kind fates have willed that we should fall just within this lucky strip. By the utmost good fortune after we passed the blazing peak which so nearly wrecked us, we were carried on by the wind so far, before the ascensional power of the car gave out, that we descended on the sunward side of the crest of the range. The sun is now just beginning to rise on the part of the strip where we are, and it will get higher for several weeks to come. The result will be that a great melting of ice and snow will occur here, and in this deep valley a river will form, flowing off toward the sunward hemisphere, exactly where we want to go. I shall take advantage of the torrent that will flow here and float down with it until we are out of the labyrinth. It's our only chance, for we couldn't possibly clamber over the hummocky ice and drag the car with us."
