immense advantage that if we were only going from Chicago to London, the trip could be more easily and quickly made by going to the westward some twenty-one thousand miles, rather than going directly eastward less than four thousand miles. For going eastward we should have to travel a thousand miles an hour in order to keep up with the Earth. It is questionable whether we could make that speed tacking up and slanting down."

"Then we shall have to follow the course of Empire, always westward!" I laughed.

While we were talking thus, the whizzing and whistling of the wind, which had been at first very loud and hissing, had gradually died down. I looked at the barometer, and reported that there was scarcely three-eighths of an inch of mercury in the tube.

"We are practically above the atmosphere, then," said the doctor, turning in all the batteries. He tried the rudder in the ether, and found it turned her when fully extended and turned rather hard over.

"I tried to sleep this morning at Whiting to prepare for to-night's work," said the doctor presently; "but I find I am getting uncontrollably drowsy. Come up, and I will show you the course[87] we most keep, and then I will lie down to get a little rest."

I mounted to his compartment and gazed through the telescope at Mars, looking like a little, red baby-moon, floating in one side of the blue circle.

"Keep him always in view, but in the edge of the field like that," said the doctor. "We must always steer a little to the right of him—that is, a little behind him."

"But he travels around the sun in the same direction the Earth does," I objected. "I should think we ought to aim a little ahead of him, or to the left, to allow for his motion forward in his orbit."

"That looks reasonable at first sight, doesn't it?" said the doctor. "But a little learning is a dangerous thing. I will explain to you why we must steer a little behind him after I have had my nap. I am too sleepy now;" and he finished with a yawn.

He soon fell asleep, and I was left alone to think over the events of the day and the still more strange happenings of the night. It hurt my eyes to look long through the telescope, so I closed them and gave free rein to my thoughts.

How soon will it be morning? How shall I know when it is morning? That term "morning" applies only to the surface of revolving planets. I had just seen the morning come at midnight, and then the darkness of night fall again directly after[88] morning. After all, what are night and morning? The one is a passing into the shadow of the Earth, and the other is simply the emerging into the light. They depend on a rotation, and we shall know no more of them until we land on a revolving planet again. But which shall we have on the trip, night or daylight? Naturally we would very soon emerge from the little shadow cast by the Earth. It had taken us but an hour or two to travel out of it into the daylight and then back into the darkness again. Even if we did not leave it, the Earth would move on and leave us.

And what then? Nothing but uninterrupted, untempered, unhindered daylight! Eternal, dazzling, direct sunlight, unrelieved by any night, unstrained through any clouds! This deep blue of the starry night would be succeeded by the hot, white light of a scorching, gleaming Sun. And then (the thought chilled my bones as it fell upon me!), then how would we see Mars? How would we see any star, or perchance the Moon? Even the Earth might be drowned in that sea of everlasting, all-engulfing brilliancy! Nothing in all the Universe would be visible but the beaming Sun, and he too blindingly bright to look upon.

As the truth of all this took hold of me, it filled me with a growing terror. At any moment we might emerge from this grateful shadow of the Earth, and then we would be lost, drowned, engulfed in a blinding, sight-suffocating light! In[89] desperate terror I looked around toward the doctor, as if for assistance. He was sleeping peacefully. He had never thought of it! This was the great thing he had overlooked! Even at starting he had a dreadful presentiment of it.

He was a great man, and his discovery a wonderful one; but here was the trouble with it. He had solved the question of navigating space, but the sunlight! the dazzling, burning, terrible sunlight! how was he to navigate that? It was simply impossible! We would have to turn back before we emerged into it. We would have to retrace our path while we were still in the grateful shadow. Ah, the blessedness of night after all!

Then slowly and cautiously, so that I might not waken him, I crept down to the rear window to see how far away the Earth was. We were at so great a distance that I could see the whole outline of it, as a great dull globe filling all the view behind us. And as I looked again I started and uttered a cry! A thin sickle of bright, white light glimmered over the whole eastern edge of it, like the first glimpse of the new Moon, but a hundred times larger! It was the sunlight! It must be creeping around the eastern edge, and would soon engulf us.

The doctor had been aroused by my cry. Not seeing me in his compartment, he had gone at once to the telescope.

"What is the matter?" he said. "You have lost the course a little." And as I peered out of my[90] port-hole I saw that narrow sickle of light grow thinner and thinner, and finally go out. Had I imagined it all? No, I had seen it.

"Ah, Doctor, I am so glad you have wakened. I am frightened, terrified, by the light!"

[91]

CHAPTER VIII The Valley of the Shadow

"Light! Where have you seen any light?"

"I saw the Earth begin to shine like a New Moon on the eastern edge, but——"

"Ah, that was a danger signal. I am glad you awakened me. But you are actually pale and trembling! There is no danger if you keep the course. You see, that rim of light has faded and disappeared since I corrected the course."

"Yes, but you cannot keep in this little Earthly shadow much longer; and what can we possibly do when we emerge into the fathomless, trackless effulgence of eternal sunshine? Let us turn back before we plunge into it," I pleaded.

"So that is what terrified you! Well, you have hit upon one of the greatest difficulties of the trip; but it is far from insurmountable. We will not turn back yet, especially as we have started in the most opportune time. You have mentioned this 'little shadow.' It is eight thousand miles wide at the surface of the Earth, and gradually, very[92] gradually, tapers down to nothing far out in space. Have you ever calculated how far it reaches?"

"No," I answered. "But we moved out of it and back into it at the surface very easily, and besides, as the Earth moves forward in its orbit, the shadow will leave us."

"This little shadow is eight hundred and fifty-six thousand miles long, and we will never leave it as long as it lasts!" exclaimed the doctor. "Just at this time it points like a long arrow out in the direction of Mars. It is moving gradually as the Earth moves and hourly correcting its aim. At opposition time it will point directly and unerringly at Mars. Therefore it is a way prepared, surveyed, and marked for us through the all-enveloping sunlight, which otherwise would be dreadful enough."

"But how can we be sure of keeping in it? It is rapidly narrowing as it reaches farther out."

"I see I should have explained that to you before I went to sleep, and saved you this fright. The shadow now points behind Mars, as it is many days yet before it overtakes that planet in opposition. That is why I told you to steer always a little behind the planet. But you went a little out of the course, and immediately something warned us. That rim of light on the east of the Earth was notice to us that we were not in the centre of the shadow, but bearing too far to the left. We must[93] keep absolutely in the dark of the Earth, with no light visible on either side of it. If a thin rim should appear on one side, we must turn toward the other until it is all dark again."

"Grant that this shadow is so enormously long, yet it is only scarcely one-fortieth of the distance to Mars," I objected. "After we emerge from it, what then?"

"With the aid of my telescope we shall probably be able to see the Earth as an orb, half or quarter as large as the Moon usually appears to us, and to observe its phases until we are several million miles from it. We must continue to keep the rim of light, which will then surround it, equal on all sides."

"Ah, but I am afraid," I interrupted, "that as soon as we pass out of this shadow the sunlight will be so bright that we cannot see any planets, not even the Earth. You know we cannot see the Moon only a quarter of a million miles away when the sun shines."

"In that case we must move the telescope to your window, put on a darkened lens, and steer so as to keep the Earth as a spot in the middle of the Sun. It must appear to us as Venus does to the Earth when she is making a transit across the face of the sun. But by our continual shifting we prevent the Earth from making a transit, and hold it as a steady spot in the centre of the Sun. This we can do for many, many million miles, continuing[94] until we have reached the vicinity of Mars.

"And you must also remember," continued the doctor, "that the brighter the light the darker will be the shadow. Now, this projectile is a perfectly black, non-reflecting object five feet wide. It will cast a shadow in front of it five hundred feet long. When we are comparatively near Mars my telescope, situated in the miniature night cast by the projectile, will find the planet, and we can then steer directly for him. If we should chance within eighty thousand miles of him, he would attract us to him in a straight line. But we shall not rely upon chance. Moreover, when we are as near to him as that, the light and heat of the Sun's rays will have decreased sixty or seventy per cent. When Mars is farthest from the Sun, he receives only one-third as much light as the Earth does. But he is now almost at his nearest point to the Sun, and receives half as much light."

"Well, you certainly have a pretty clear idea of how to steer the course all the way, Doctor. And I was hasty enough to think you had overlooked this entire phase of the subject!" I ejaculated.

"Indeed, I have thought of it very much. And we should not enjoy all these advantages if we had not started just before opposition. At any other time the Earth's shadow would not point toward Mars, nor would the transit of the Earth over the Sun be of any use to us."[95]

"All this reassures me greatly," I replied; "but I shall keep a close watch from my rear window for danger lights on the Earth."

"It must be time for breakfast," put in the doctor. "Will you see how tempting a meal you can prepare?"

There was one reservoir built inside the compartments, from which we drew cool water, and another built next to the outer steel framework, from which we could draw boiling water. As this tank was connected with the discharge pipe of the air-pump, and thus with the exterior, I was disgusted to find that, although the water boiled furiously, and was rapidly wasting away in steam, it did not become hot enough to make good beef tea. The heat escaped with the steam at a comparatively low temperature, so that I was compelled to boil water over my gas jet for the meat extract, which we drank instead of coffee. I also prepared some sandwiches of roast beef and cold ham, and with great relish we began our diet of ready cooked foods, which was to continue for so long.

After this meal I felt quite sleepy, for I had enjoyed but three hours' rest. The doctor saw my yawns and told me to turn out the gas and have a long doze, and I was glad enough to do so.

I must have slept soundly for an hour or two, and then I remember dozing and rolling lazily in my bed, as I usually
