that worthy muttered. "I have to be, now that you've got the drop on me and DuQuesne's gone back on me. But wait until we get back! I'll get you then, you...."
"Stop right there!" sharply. "There's nothing I would rather do than shoot you right now, if you give me the slightest excuse, such as that name you were about to call me. Now go ahead!"
DuQuesne broke the silence that followed.
"Well, now that the battle is over, and since we are fed and rested, I suggest that we slow down a bit and get ready to start back. Pick out comfortable seats, everybody, and I'll shoot a little more juice through that bar."
Seating himself before the instrument board, he advanced the speed lever slowly until nearly three-quarters of the full power was on, as much as he thought the others could stand.
For sixty hours he drove the car, reducing the acceleration only at intervals during which they ate and walked about their narrow quarters in order to restore the blood to circulation in their suffering bodies. The power was not reduced for sleep; everyone slept as best he could.
Dorothy and Margaret talked together at every opportunity, and a real intimacy grew up between them. Perkins was for the most part sullenly quiet, knowing himself despised by all the others and having no outlet here for his particular brand of cleverness. DuQuesne was always occupied with his work and only occasionally addressed a remark to one or another of the party, except during meals. At those periods of general recuperation, he talked easily and well upon many topics. There was no animosity in his bearing nor did he seem to perceive any directed toward himself, but when any of the others ventured to infringe upon his ideas of how discipline should be maintained, DuQuesne's reproof was merciless. Dorothy almost liked him, but Margaret insisted that she considered him worse than ever.
When the bar was exhausted, DuQuesne lifted the sole remaining cylinder into place.
"We should be nearly stationary with respect to the earth," he remarked. "Now we will start back."
"Why, it felt as though we were picking up speed for the last three days!" exclaimed Margaret.
"Yes, it feels that way because we have nothing to judge by. Slowing down in one direction feels exactly like starting up in the opposite one. There is no means of knowing whether we are standing still, going away from the earth, or going toward it, since we have nothing stationary upon which to make observations. However, since the two bars were of exactly the same size and were exerted in opposite directions except for a few minutes after we left the earth, we are nearly stationary now. I will put on power until this bar is something less than half gone, then coast for three or four days. By the end of that time we should be able to recognize our solar system from the appearance of the fixed stars."
He again advanced the lever, and for many hours silence filled the car as it hurtled through space. DuQuesne, waking up from a long nap, saw that the bar no longer pointed directly toward the top of the ship, perpendicular to the floor, but was inclined at a sharp angle. He reduced the current, and felt the lurch of the car as it swung around the bar, increasing the angle many degrees. He measured the angle carefully and peered out of all the windows on one side of the car. Returning to the bar after a time, he again measured the angle, and found that it had increased greatly.
"What's the matter, Doctor DuQuesne?" asked Dorothy, who had also been asleep.
"We are being deflected from our course. You see the bar doesn't point straight up any more? Of course the direction of the bar hasn't changed, the car has swung around it."
"What does that mean?"
"We have come close enough to some star so that its attraction swings the bottom of the car around. Normally, you know, the bottom of the car follows directly behind the bar. It doesn't mean much yet except that we are being drawn away from our straight line, but if the attraction gets much stronger it may make us miss our solar system completely. I have been looking for the star in question, but can't see it yet. We'll probably pull away from it very shortly."
He threw on the power, and for some time watched the bar anxiously, expecting to see it swing back into the vertical, but the angle continually increased. He again reduced the current and searched the heavens for the troublesome body.
"Do you see it yet?" asked Dorothy with concern.
"No, there's apparently nothing near enough to account for all this deflection."
He took out a pair of large night-glasses and peered through them for several minutes.
"Good God! It's a dead sun, and we're nearly onto it! It looks as large as our moon!"
Springing to the board, he whirled the bar into the vertical. He took down a strange instrument, went to the bottom window, and measured the apparent size of the dark star. Then, after cautioning the rest of the party to sit tight, he advanced the lever farther than it had been before. After half an hour he again slackened the pace and made another observation, finding to his astonishment that the dark mass had almost doubled its apparent size! Dorothy, noting his expression, was about to speak, but he forestalled her.
"We lost ground, instead of gaining, that spurt," he remarked, as he hastened to his post. "It must be inconceivably large, to exert such an enormous attractive force at this distance. We'll have to put on full power. Hang onto yourselves as best you can."
He then pushed the lever out to its last notch and left it there until the bar was nearly gone, only to find that the faint disk of the monster globe was even larger than before, being now visible to the unaided eye. Revived, the three others saw it plainly—a great dim circle, visible as is the dark portion of the new moon—and, the power shut off, they felt themselves falling toward it with sickening speed. Perkins screamed with mad fear and flung himself grovelling upon the floor. Margaret, her nerves still unstrung, clutched at her heart with both hands. Dorothy, though her eyes looked like great black holes in her white face, looked DuQuesne in the eye steadily.
"This is the end, then?"
"Not yet," he replied in a calm and level voice. "The end will not come for a good many hours, as I have calculated that it will take at least two days, probably more, to fall the distance we have to go. We have all that time in which to think out a way of escape."
"Won't the outer repulsive shell keep us from striking it, or at least break the force of our fall?"
"No. It was designed only as protection from meteorites and other small bodies. It is heavy enough to swing us away from a small planet, but it will be used up long before we strike."
He lighted a cigarette and sat at case, as though in his own study, his brow wrinkled in thought as he made calculations in his notebook. Finally he rose to his feet.
"There's only one chance that I can see. That is to gather up every scrap of copper we have and try to pull ourselves far enough out of line so that we will take an hyperbolic orbit around that body instead of falling into it."
"What good will that do us?" asked Margaret, striving for self-control. "We will starve to death finally, won't we?"
"Not necessarily. That will give us time to figure out something else."
"You won't have to figure out anything else, Doctor," stated Dorothy positively. "If we miss that moon, Dick and Martin will find us before very long."
"Not in this life. If they tried to follow us, they're both dead before now."
"That's
