The remaining three, however, were flying on, buffeted hard but keeping to their course. More lightning flashed around them, and as the storm came closer, Lee began to fear for the gas in his own balloon. One strike could have it tumbling to earth in flames, and he didn't suppose the shaman could control the storm so finely as to avoid that.

"Right, Dr. Grumman," he said. "I'm going to ignore those zeppelins for now and concentrate on getting us safe into the mountains and on the ground. What I want you to do is sit tight and hold on, and be prepared to jump when I tell you. I'll give you warning, and I'll try to make it as gentle as I can, but landing in these conditions is a matter of luck as much as skill."

"I trust you, Mr. Scoresby," said the shaman.

He sat back in a corner of the basket while his daemon perched on the suspension ring, her claws dug deep in the leather binding.

The wind was blowing them hard now, and the great gasbag swelled and billowed in the gusts. The ropes creaked and strained, but Lee had no fear of their giving way. He let go some more ballast and watched the altimeter closely. In a storm, when the air pressure sank, you had to offset that drop against the altimetric reading, and very often it was a crude rule-of-thumb calculation. Lee ran through the figures, double-checked them, and then released the last of his ballast. The only control he had now was the gas valve. He couldn't go higher; he could only descend.

He peered intently through the stormy air and made out the great bulk of the hills, dark against the dark sky. From below there came a roaring, rushing sound, like the crash of surf on a stony beach, but he knew it was the wind tearing through the leaves on the trees. So far, already! They were moving faster than he'd thought.

And he shouldn't leave it too long before he brought them down. Lee was too cool by nature to rage at fate; his manner was to raise an eyebrow and greet it laconically. But he couldn't help a flicker of despair now, when the one thing he should do—namely, fly before the storm and let it blow itself out—was the one thing guaranteed to get them shot down.

He scooped up Hester and tucked her securely into his breast, buttoning the canvas coat up close to keep her in. Grumman sat steady and quiet; his daemon, wind-torn, clung firmly with her talons deep in the basket rim and her feathers blown erect.

"I'm going to take us down, Dr. Grumman," Lee shouted above the wind. "You should stand and be ready to jump clear. Hold the ring and swing yourself up when I call."

Grumman obeyed. Lee gazed down, ahead, down, ahead, checking each dim glimpse against the next, and blinking the rain out of his eyes; for a sudden squall had brought heavy drops at them like handfuls of gravel, and the drumming they made on the gasbag added to the wind's howl and the lash of the leaves below until Lee could hardly even hear the thunder.

"Here we go!" he shouted. "You cooked up a fine storm, Mr. Shaman."

He pulled at the gas-valve line and lashed it around a cleat to keep it open. As the gas streamed out of the top, invisible far above, the lower curve of the gasbag withdrew into itself, and a fold, and then another, appeared where there had been a bulging sphere only a minute before.

The basket was tossing and lurching so violently it was hard to tell if they were going down, and the gusts were so sudden and wayward that they might easily have been blown high into the sky without knowing; but after a minute or so Lee felt a sudden snag and knew the grapnel had caught on a branch. It was only a temporary check, so the branch had broken, but it showed how close they were.

He shouted, "Fifty feet above the trees—"

The shaman nodded.

Then came another snag, more violent, and the two men were thrown hard against the rim of the basket. Lee was used to it and found his balance at once, but the force took Grumman by surprise. However, he didn't lose his grip on the suspension ring, and Lee could see him safely poised, ready to swing himself clear.

A moment later came the most jolting shock of all as the grapnel found a branch that held it fast. The basket tilted at once and a second later was crashing into the treetops, and amid the lashing of wet leaves and the snapping of twigs and the creak of tormented branches it jolted to a precarious halt.

"Still there, Dr. Grumman?" Lee called, for it was impossible to see anything.

"Still here, Mr. Scoresby."

"Better keep still for a minute till we see the situation clearly," said Lee, for they were wildly swaying in the wind, and he could feel the basket settling with little jerks against whatever was holding them up.

There was still a strong sideways pull from the gasbag, which was now nearly empty, but which as a result was catching the wind like a sail. It crossed Lee's mind to cut it loose, but if it didn't fly away altogether, it would hang in the treetops like a banner and give their position away; much better to take it in, if they could.

There came another lightning flash, and a second later the thunder crashed. The storm was nearly overhead. The glare showed Lee an oak trunk, with a great white scar where a branch had been torn away, but torn only partially, for the basket was resting on it near the point where it was still attached to the trunk.

"I'm going to throw out a rope and climb down," he shouted. "As soon as our feet touch the ground, we can make the next plan."

"I'll follow you, Mr. Scoresby," said Grumman. "My daemon tells me the ground is forty feet down."

And Lee was aware of a powerful flutter of wingbeats as the eagle daemon settled again on the basket rim.

"She can go that far?" he said, surprised, but put that out of his mind and made the rope secure, first to the suspension ring and then to the branch, so that even if the basket did fall, it wouldn't fall far.

Then, with Hester secure in his breast, he threw the rest of the rope over and clambered down till he felt solid ground beneath his feet. The branches grew thick around the trunk; this was a massive tree, a giant of an oak, and Lee muttered a thank-you to it as he tugged on the rope to signal to Grumman that he could descend.

Was there another sound in the tumult? He listened hard. Yes, the engine of a zeppelin, maybe more than one, some way above. It was impossible to tell how high, or in which direction it was flying; but the sound was there for a minute or so, and then it was gone.

The shaman reached the ground.

"Did you hear it?" said Lee.

"Yes. Going higher, into the mountains, I think. Congratulations on landing us safely, Mr. Scoresby."

"We ain't finished yet. I want to git that gasbag under the canopy before daybreak, or it'll show up our position from miles away. You up to some manual labor, Dr. Grumman?"

"Tell me what to do."

"All right. I'm going back up the rope, and I'll lower some things down to you. One of them's a tent. You can git that set up while I see what I can do up there to hide the balloon."

They labored for a long time, and in peril at one point, when the branch that had been supporting the basket finally broke and pitched Lee down with it; but he didn't fall far, since the gasbag still trailed among the treetops and held the basket suspended.

The fall in fact made concealing the gasbag easier, since the lower part of it had been pulled down through the canopy; and working by flashes of lightning, tugging and wrenching and hacking, Lee managed to drag the whole body of the balloon down among the lower branches and out of sight.

The wind was still beating the treetops back and forth, but the worst of the rain had passed by the time he decided he could do no more. He clambered down and found that the shaman had not only pitched the tent but had conjured a fire into being, and was brewing some coffee.
