Now they were in the business of elephant hunting.

Though the pachyderms were immune to the venom on the darts propelled by certain plants, they succumbed to that deriv from the "yew" trees. At the end of another month, they had more than the supply of elephant stomach lining needed. The membranes weighed, per square yard, two-thirds less than the gazelle hides. Anana stripped the hides from the parawings and replaced them with the membranes.

"I think the wings'll be light enough now to work in the planet's field," she said. "In fact, I'm sure. I wasn't too certain about the hides."

Another plant yielded, after much hard work and some initial failures, a glue-like substance. This could seal the edges of the strips which would compose the balloon envelope. They sealed some strips of membrane together and tested them over a fire. Even after twenty hours, the glue did not deteriorate. But with thirty hours' of steady temperature, it began to decompose.

"That's fine," Anana said. "We won't be in the balloon more than an hour, I hope. Anyway, we can't carry enough wood to burn for more than an hour's flight."

It looks like we might make it after all," Kickaha said. "But what about her?"

He gestured at Shoobam.

"She's saved our necks or at least given us a fighting chance? But what're we going to do with her when we lift off? We can't just leave her. But we can't take her with us, either."

Anana said, "Don't worry about that. I've talked with her about it. She knows we'll be leaving some day. But she's grateful that she's lived this long, not to mention that we've given her more food than she's had for a long time."

"Yes? What happens when we go?"

"I've promised to slit her wrists." Kickaha winced. "You're a better man than I am, Gunga Din. I don't think I could do it."

"You have a better idea?"

"No. If it has to be, so be it. I suppose I would do it, but I'm glad I don't have to."

ANANA DECIDED THAT it would be better to make three smaller balloons instead of one large one.

"Here's how it is. To get equal strength the material of a large balloon has to be much stronger and heavier per square inch than that of a smaller balloon. By making three smaller ones, instead of one large one, we gain in strength of material and lose in weight. So, each of us will ascend in his aerostat."

She added, "Also, since the smaller ones won't present as much area to the wind, they'll be easier to handle."

Kickaha had lost too many arguments with her to object.

McKay resented being "bossed" by a woman, but he had to admit that she was the authority.

They worked frantically to make the final preparations. Even Shoobam helped, and the knowledge of what would happen on the day of liftoff did not shadow her cheeriness. At least, if she felt sorrow or dread, she did not show it.

Finally, the time came. The three bags lay on the ground, stretched out behind the wall of the windbreak. A net of thin but tough cured membrane strips enclosed each bag. These, the suspension ropes, were attached directly to the basket. Anana would have liked to have tied them to a suspension hoop below which the basket would be hung by foot ropes. This arrangement afforded better stability.

However, it was almost impossible to carve three rings from wood. Besides, if the ring was made strong enough to stand up under the weight of the basket, its passenger, and the fuel, it would have to be rather heavy.

The ends of the suspension ropes were tied to the corners and along the sides of a rectangular car or basket made of pieces of bark glued together. In the center of the car was a thick layer of earth, on top of which were piled sticks. Wood shavings were packed at the bottom of the pile so the fire could be started easily. A layer of tinder would be ignited by sparks from a flint and a knife or the axe.

The wall of earth serving as a windbreak had been tumbled over four times because of the shape-changing of terrain. The fifth one was almost twice as high and four times as long as the one built for the test balloon. It was roofed over by branches laid on cross-logs supported by uprights.

Three gallows, primitive cranes, stood near the open end of the enclosure. A cable made of twisted cords ran from the upper sides of the horizontal arm to the top of the balloon. One end was tied around the top of the balloon.

The three people pulled the envelopes up, one by one, until all three hung limply below the gallows arms. The ends of the hoist ropes were secured to nearby uprights. McKay, who had wanted to be first to lift off, probably because it made him nervous to wait, lit the fire. Smoke began to ascend into a circular skin hanging down from the neck of the balloon.

When the bag had started to swell from the expanding hot air, Anana lit the fire in her car. Kickaha waited a few minutes and then started a flame in his basket.

The bands of the "dawn" sky began to glow. Snorts and barks and one roar came from the animals on the plains, awakening to another day of feeding and being fed upon. The wind was at an estimated minimum eight miles an hour velocity and without gusts.

McKay's envelope began to inflate. As soon it was evident that it would stand up by itself, McKay leaped up past the balloon, reached out with his axe, and severed the cable attached to the top. He fell, hack, landing at the same time the cable did. After rising, he waited another minute, then pulled the balloon from beneath the gallows by the basket.

When Anana's balloon had lifted enough to support itself, she cut the cable, and Kickaha soon did the same to his.

Shoobam, who had been sitting to one side, pulled herself up on the crutch and hobbled over to Anana. She spoke in a low tone, Anana embraced her, then slashed at the wrists held out to her. Kickaha wanted to look away, but he thought that if someone else did the dirty work he could at least observe it.

The old woman sat down by Anana's basket and began wailing a death chant. She didn't seem to notice when he waved farewell.

Tears were running down Anana's cheeks, but she was busy feeding the fire.

McKay shouted, "So long! See you later! I hope!"

He pulled the balloon out until it was past the overhang. Then he climbed quickly aboard the car, threw on some more sticks, and waited. The balloon leaned a little as the edge of the wind coming over the roof struck its top. It began rising, was caught by the full force of the moving air, and rose at an angle.

Anana's craft ascended a few minutes later. Kickaha's followed at the same interval of time.

He looked up the bulge of the envelope. The parawing was still attached to the net and was undamaged. It had been tied to the upper side when the bag had been laid out on the ground. An observer at a distance might have thought it looked like a giant moth plastered against a giant light bulb.

He was thrilled with his flight in an aerostat. There had been no sensation of moving; he could just as well have been on a flying carpet. Except that there was no wind against his face. The balloon moved at the same speed as the air.

Above and beyond him the other two balloons floated. Anana waved once, and he waved back. Then he tended the fire.

Once he looked back at the windbreak. Shoo-bam was a dim tiny figure who whisked out of sight as the roof intervened.

The area of vision expanded; the horizon rushed outwards. Vistas of mountains and plains and here and there large bodies of water where rain had collected in temporary depressions spread out for him.

Above them hung the vast body of the primary. The great wound made by the splitoff had healed. The mother planet was waiting to receive the baby, waiting for another cataclysm.
