He made a gesture to the Keeper of Foodstuffs. It was unconsciously an authoritative gesture, though the Keeper of Foodstuffs was in the state of affairs in Yugna the head of the Council. But that old man spoke deliberately. The man from Rahn snarled his reply. And Tommy turned aside as the bargaining went on. He could see Evelyn down below, a tiny speck of khaki amid the rainbow-colored robes of the other women. This had been a savage expedition, to rescue or to avenge. It had deteriorated into a bargain. Tommy heard, dully, amounts of unfamiliar weights and measures of foodstuffs he did not recognize. He heard the time and place of payment named: the gate of Yugna, the third dawn hence. He hardly looked up as at some signal one of their own ornithopters slid below and the three amba.s.sadors of Rahn prepared to go over the side. But Jacaro snarled out of one corner of his mouth.

"These guys are takin' each other's words. Maybe that's all right, but I'm warnin' you, if there's any double-crossin'...."

He was gone. The Keeper of Foodstuffs touched Tommy's shoulder.

"Our flier," he said slowly, "will make sure our women are as yet unharmed. We are to deliver the foods at our own city gate, and after the women have been returned. Rahn dares not keep them or harm them.

We of Yugna keep our word. Even in Rahn they know it."

"But they won't keep theirs," said Tommy heavily. "Not with a man of Earth to lead them."

He watched with his heart in his mouth as the ornithopter alighted near the a.s.sembled women of Yugna. As the three amba.s.sadors climbed out, he could hear the faint murmur of voices. The men of Yugna, under truce, called across the landing stage to the women of their own city, and the women replied to them. Then the crew of the one grounded freighter arrived on the landing stage and the flapping flier rose slowly and rejoined the fleet. Its crew shouted a shamefaced rea.s.surance to the flagship.

"I suppose," said Tommy bitterly, "we'd better go back--if you're sure the women are safe."

"I am sure," said the old man unhappily, "or I had not agreed to pay half the foodstuffs in Yugna for their return."

He withdrew into a troubled silence as the fleet swept far from triumphantly for him. Denham had not spoken at all, though his eyes had blazed savagely upon the men of Rahn. Now he spoke, dry-throatedly:

"Tommy--Evelyn--"

"She is all right so far," said Tommy bitterly. "She's to be ransomed by foodstuffs, paid at the gates of Yugna. And Jacaro bragged he's running Rahn--and they've got gas masks. We'd better be ready for trouble after the women are returned."

Denham nodded grimly. Tommy reached out and took one of the black tablets from the man beside him. He began to draw carefully, his eyes savage.

"What's that?"

"There's high-pressure steam in Yugna," said Tommy coldly. "I'm designing steam guns. Gravity feed of spherical projectiles. A jet of steam instead of gunpowder. They'll be low-velocity, but we can use big-calibre b.a.l.l.s for shock effect, and with long barrels they ought to serve for a hundred yards or better. Smooth bore, of course."

Denham stirred. His lips were pinched.

"I'll design a gas mask," he said restlessly, "and Smithers and I, between us, will do what we can."

The air fleet went on over the waving tree-fern jungle in an unvarying monotony of bitterness. Presently Tommy wearily explained his design to the bearded Councilor who, with the quick comprehension of mechanical design apparently instinctive in these folk, grasped it immediately. He selected three of the six-man crew and pa.s.sed Tommy's drawings to them. While the jungle flowed beneath the fleet they studied the sketches, made other drawings, and showed them eagerly to Tommy. When the fleet soared down to the scattered landing stages, not only was the design understood but apparently plans for production had been made. It did not take the men of the Golden City long to respond.

Tommy flung himself savagely into the work he had taken upon himself.

It did not occur to him to ask for authority. He knew what had to be done and he set to work to do it, commanding men and materials as if there could be no question of disobedience. As a matter of fact, he yielded impatiently to an order of the Council that he should present himself in the Council hall, and, since no questions were asked him, continued his organizing in the very presence of the Council, sending for information and giving orders in a low tone while the Council deliberated. A vote was taken by the voting machine. At its end, he was solemnly informed that, though not a native of Yugna, he was entrusted with the command of the defense forces of the city. His skill in arms--as evidenced by his defeat of the fleet of Rahn--and his ability in command--when he met the gas-mask defense of Rahn with a threat of starvation--moved the Council to that action. He accepted the command almost abstractedly, and hurried away to pick gun emplacements.

Within four hours after the return of the fleet, the first steam gun was ready for trial. Smithers appeared, sweat-streaked and vastly calm, to announce that others could be turned out in quant.i.ty.

"These guys have got the stuff," he said steadily. "Instead o' castin'

their stuff, they shoot it on a core in a melted spray. They ain't got steel, an' copper's scarce, but they got some alloys that are good an'

tough. One's part tungsten or I'm crazy."

Tommy nodded.

"Turn out all the guns you can," he said. "I look for fighting."

"Yeah," said Smithers. "Miss Evelyn's still all right?"

"Up to three hours ago," said Tommy grimly. "Every three hours one of our ships lands in Rahn and reports. We give the Rahnians their stuff at our own city gates. I've warned Jacaro that we've mounted thermit-throwers on our food stores. If he manages to gas us by surprise, nevertheless our foodstuffs can't be captured. They've got to turn over Evelyn and cart off their food before they dare to fight, else they'll starve."

"But--uh--there're other cities they could stick up, ain't there?"

"We've warned them," said Tommy curtly. "They've got thermit-throwers mounted on their food supplies, too. And they're desperate enough to keep Rahn off. They're willing enough to let Yugna do the fighting, but they know what Rahn's winning will mean."

Smithers turned away, then turned back.

"Uh--Mr. Reames," he said heavily, "these fellas've gone near crazy about governors an' reducing valves an' such. They're inventin' ways to use 'em on machines I don't make head or tail of. We got three-four hundred men loose from machines already, an' they're turnin' out these steam guns as soon as you check up. There'll be more loose by night. I had 'em spray some castin's for another Tube, too. Workin' like they do, an' with the tools they got, they make speed."

Tommy responded impatiently: "There's no steel, no iron for magnets."

"I know," admitted Smithers. "I'm tryin' steam cylinders to--uh--energize the castin's, instead o' coils. It'll be ready by mornin'. I wish you'd look it over, Mr. Reames. If Miss Evelyn gets safe into the city, we could send her down the Tube to Earth until the fightin's over."

"I'll try to see it," said Tommy impatiently. "I'll try!"

He turned back to the set-up steam gun. A flexible pipe from a heavily insulated cylinder ran to it. A hopper dropped metallic b.a.l.l.s down into a bored-out barrel, where they were sucked into the blast of superheated steam from the storage cylinder. At a touch of the trigger a monstrous cloud of steam poured out. It was six feet from the gun muzzle before it condensed enough to be visible. Then a huge white cloud developed; but the metal pellets went on with deadly force. Half an inch in diameter, they carried seven hundred yards at extreme elevation. Point-blank range was seventy-five yards. They would kill at three hundred, and stun or disable beyond that. At a hundred yards they would tear through a man's body.

Tommy was promised a hundred of the weapons, with their boilers, in two days. He selected their emplacements. He directed that a disabling device be inserted, so if rushed they could not be turned against their owners. He inspected the gas masks being turned out by the women, who in this emergency worked like the men. Though helpless before machinery, it seemed, they could contrive a fabric device like a gas mask.

The second day the work went on more desperately still. But Smithers'

work in releasing men was telling. There were fifteen hundred governors, or reducing valves, or autocratic cut-outs in operation now. And fifteen hundred men were released from the machines, which had to be kept going to keep the city alive. With that many men, intelligent mechanics all, Tommy and Smithers worked wonders. Smithers drove them mercilessly, using profanity and mechanical drawings instead of speech. Denham withdrew twenty men and labored on top of one of the towers. Toward sunset of the second day, vast clouds of steam bellied out from it at odd, irregular intervals. Nothing else manifested itself. Those irregular belchings of steam continued until dark, but Tommy paid no attention to them. He was driving the gunners of the machine guns to practice. He was planning patrols, devising a reserve, mounting thermit-throwers, and arranging for the delivery of the promised ransom at the specified city gate. So far, there was no sign of anything unusual in Rahn. Messengers from Yugna saw the captive women regularly, once every three hours. The last to leave had reported them being loaded into great ground vehicles under a defending escort, to travel through the dark jungle roads to Yugna. A vast concourse of empty vehicles was trailing into the jungle after them, to bring back the food which would keep Rahn from starving, for a while. It all seemed wholly regular.

At dawn, the remaining ships of the air fleet of Rahn were soaring silently above the jungle about the Golden City. They made no threat.

They offered no affront. But they soared, and soared....

A little after dawn, glitterings in the jungle announced the arrival of the convoy. Messengers, in advance, shouted the news. Men from Yugna went out to inspect. The atmosphere grew tense. The air fleet of Rahn drew closer.

Slowly, a great golden gateway yawned. Four ground vehicles rolled forward, and under escort of the Rahnians entered the city. Half the captive women from Yugna were within them. They alighted, weeping for joy, and were promptly whisked away. Evelyn was not among them. Tommy ground his teeth. An explanation came. When one half the promised ransom was paid, the others would be forthcoming.

Tommy gave grim orders. Half the foodstuffs were taken to the city gate--half, no more. At his direction, it was explained gently to the Rahnians that the rest of the ransom remained under guard of the thermit-throwers. It would not be exposed to capture until the last of the captives were released. There was argument, expostulation. The rest of the women appeared. Aten, at Tommy's express command, piled Evelyn and his own wife into a ground vehicle and came racing madly to the tower from which Tommy could see all the circuit of the city.

"You're all right?" asked Tommy. At Evelyn's speechless nod, he put his hand heavily on her shoulder. "I'm glad," he managed to say. "Put on that gas mask. h.e.l.l's going to pop in a minute."

He watched, every muscle tense. There was confusion about the city gate. Ground vehicles, loaded with foodstuffs, poured out of the gate and back toward the jungle. Other vehicles with improvised enlargements to their carrying platforms--making them into huge closed boxes--rolled up to the gate. The loaded vehicles rolled back and back and back, and ever more apparently empty ones crowded about the city gate waiting for admission.

Then there was a sudden flare of intolerable light. A wild yell arose.

Clouds of steam shot up from the ready steam guns. But the circling air fleet turned as one ship and plunged for the city. The leaders began to drop smoking things that turned into monstrous pillars of prismatically-colored mist. A wave of deadly vapor rolled over the ramparts of the city. And then there was a long-continued ululation and the noise of battle. Ragged Men, hidden in the jungle, had swarmed upon the walls with ladders made of jungle reeds. They came over the parapet in a wave of howling madness. And they surged into the city, flinging gas bombs as they came.
