A Thousand Degrees Below Zero by Murray Leinster (smart books to read .txt) 📖

their shells burst near Varrhus. He began to swerve, to zigzag, using tactics strangely like those of a dragon fly. Suddenly he darted to a point exactly above the small boat, and a smoky cloud began to dart down from below his machine. Varrhus passed on, but the cloud fell swiftly, precisely like the cloud of liquified gas he had poured down on Teddy and Davis above New York harbor.

"Flares!" cried Davis in an agony of apprehension, though his voice was only audible to Teddy by means of the telephone connection between the two helmets.

As he spoke the men on the boat shot up the little fire balls that had protected the aëroplane in its former fight. A dozen balls of light sped up to meet the menacing cloud of liquified gas. They reached it, sped into it, glowing feebly! The white cloud did not ignite, but fell on toward the boat. It reached and enveloped the little vessel, and suddenly the guns were still.

"Damn him!" said Teddy in a voice that shook with rage. "He's not using hydrogen. We can't close in on him now. Our flares are no good."

Davis tilted the nose of his machine upward, and Teddy stared down his sights. He pulled the trigger. The gun kicked backward, but the recoil cylinders did their work. The tracer shell left a little line of smoke behind it. It passed below the black body.

"Too low," said Teddy grimly, and fired again.

Varrhus began to climb. Straight up his machine went, but with the picric acid giving added impetus to the explosions in the cylinders the two-seater climbed as rapidly. Varrhus' ascent swerved. He was directly over the aëroplane. A whitish cloud appeared below his machine and blotted it out for an instant.

"We zoom," said Davis almost gayly, and the fighting plane seemed to be dancing on its tail for an instant. The cloud of gas unfolded itself down to the surface of the water, barely twenty yards before the space in which Davis had checked his course.

Around and around a huge circle. The biplane had caught up with the black flyer, and Davis turned toward it for an instant to give Teddy an opportunity to fire. There was a flash at the stern of the slender black body, and the symmetry of the glistening form was marred by a ragged edge where the tip of the tail had been blown off.

"Almost," said Teddy grimly.

"He'll dive now."

Davis was prepared for the maneuver, and almost as soon as the helicopter began to drop the biplane darted down after it, Teddy firing viciously. The streaks of smoke that his shells left behind them told him where he missed. Varrhus shifted the course of his fall, and again a cloud drifted in the air just before the pursuing plane. Davis flung the "joy-stick" forward, and the fighter fell into an absolutely vertical dive. A second more and it had turned upon its back and was flying upside down, away from the threatening mist.

Davis twisted in mid-air and righted his machine. Varrhus was darting away, barely two hundred feet above the surface of the water. Again the two-seater dived upon him. Teddy's shells were zipping dangerously near the black machine. It began to zigzag, to twist and turn like a snake. It doubled back and shot directly under the biplane, but too far below for the deadly mist to be used. Davis banked at a suicidal angle and went after it again. They passed directly above the silent small boat, drifting aimlessly on the waves. Little icicles were forming on the bulwarks, showing that the cold of the liquified gas was still intense.

For one instant Teddy had a perfect sight, and pulled the trigger with the peculiar confidence of a marksman who knows he is making a perfect shot. There was a flash upon the upper portion of the black hull. A dark object shot off at a tangent from one of the whirring disks. The helicopter sank rapidly. Teddy gave a shout.

"Landed!"

The black machine recovered again. One of the disks was badly injured and now slowed and stopped, showing that the blade of one of the four sustaining propellers had been broken, but the remaining three increased their speed. Varrhus seemed to abandon the idea of fighting. He began to shoot away toward the northeast. He was more than a mile away, and Teddy had stopped firing. Varrhus had had no difficulty in distancing the same machine a week before, and anticipated no trouble in losing it, even with his own flyer partially crippled. He had not reckoned on the picric compound now being used for fuel. The biplane sped madly after the fleeing black aircraft. The motors roared hugely, and the wind was like a solid mass, pushing fiercely against Teddy's exposed head. A small half-moon of glass protected Davis from the wind, but for the gunner no such protection was practicable. The rushing of the wind through the wires and along the sides of the stream-line body amounted to a shriek. Never had such speed been known before.

Davis' voice came quietly to Teddy above the sounds outside, muted by the heavy, padded helmet. The telephone receivers were fast against Teddy's ears.

"We're making two hundred and twenty-six."

"We're not gaining," said Teddy grimly.

"Wait until he rises. The motor's adjusted to be most efficient at about seven thousand feet."

The black speck ahead of them was drawing no nearer, it is true, but it was not dwindling. The silvery wings of the biplane cut through the air with fierce impatience. It flew in the straightest of straight lines after the other craft. Dark-brownish smoke blew backward from the bellowing exhausts, tinged almost to saffron by the presence of the explosive acid. The sunlight kissed the upper surfaces of the wings of the pursuing plane. Below them the ocean rolled and tossed.

Whistling wind and roaring engines. Speed, speed, speed! The biplane rushed with incredible swiftness through the air. The black flyer skimmed lightly on, barely in advance of its white-winged enemy. Twice Teddy essayed a shot, but the biplane trembled so that accuracy was impossible, and he could see by the smoke of his tracer shell that he had gone far wide of the black machine. The space between the black speck and the waves below it seemed to increase.

"Rising," said Davis. "Now we'll get him."

Teddy kept his eyes fixed on Varrhus' slender, needlelike craft. He was barely conscious of the upward tilt of the machine in which he was riding, but he saw that they were keeping pace with Varrhus as he rose in the air.

"Four thousand feet," said Davis crisply. "And two hundred and twenty-nine miles an hour. There's land ahead."

Teddy saw a mountainous coast line becoming visible far away. The black flyer continued to rise.

"Six thousand feet," said Davis again, "and two hundred and thirty-two miles——"

The pilot of the other machine saw that they were gaining. He dropped abruptly.

"Now!" exclaimed Davis fiercely.

He dived downward. The descent, coupled with the immense power of the engines—now delivering vastly more than the eight hundred horse power for which they were designed—made them shoot toward the black flyer with increasing speed. The other machine was barely more than half a mile away and every detail of its construction was visible. Teddy noticed for the first time a slender tube rising between the two center sustaining propellers. He instantly leaped to the conclusion that it was the means by which the jets of liquified gas had been shot out. He fired.

"A hit!" cried Davis.

There had been a flash from the top of the cabin. A jagged rent appeared in the polished roofing, and the slender tube vanished. The black flyer seemed to abandon all hopes of escape. It sped madly for a gap between two of the tall mountains that rose along the coast line. At the unprecedented speed with which both machines had been traveling the coast seemed fairly to rush at them. No villages were visible, but it seemed to be a habitable, if not an inhabited, land. The black flyer swept on across country, Varrhus evidently making every effort to gain even a few yards on his adversaries, and Davis just as fiercely determined that he should not. Once, twice, three times Teddy fired.

A smoothed and inclosed field, almost surrounded with small buildings, appeared. Varrhus dashed toward it desperately, the white-winged biplane vengefully after him. The black flyer dropped like a stone and the biplane dived straight for it. In that last dive Teddy worked his one-pounder as coolly as if at target practice. Flash! Flash! The black flyer crumpled and fell the last fifty feet as an inert mass.

Teddy jumped from the biplane as it flattened out and settled to the ground. With his automatic pistol drawn and ready, he darted toward the partly wrecked black machine. As he drew near a sallow face came weakly to a window of the cabin. An automatic flashed from beside the face and Teddy heard a queer sound and a fall behind him. He did not stop, but rushed on, shooting viciously at the face in the opening. He reached the wreck, wrenched open the door, and swung into the cabin with utter disregard for danger.

A tall, lean, sallow man was sitting exhausted in the pilot's seat of the black flyer. His right arm was crimsoned from a wound in his shoulder, and blood spurted in little frothy jets from a second wound in his neck. Teddy's fire had been better directed than he knew. As he entered with pistol ready, the sallow man raised his head erect by a tremendous effort. A hooked nose, a merciless mouth, and blazing eyes filled Teddy with repulsion. The sallow man stared at him superciliously.

"I am Wladislaw Varrhus, dictator of all the earth," he said in a metallic voice. "I command—I—command."

Speech failed him. His head dropped and he fell limply from the cushioned seat.

CHAPTER XI.

Teddy felt the fallen man's breast, but he was not breathing. In any event there was nothing that could have been done for him. An artery had been cut by a splinter of the one-pounder shell that had smashed the roof, and he had bled quietly to death, only trying desperately to land and get assistance before he died. The sight of Teddy and Davis sprinting toward him with drawn pistols had been too much for his hatred, however, and he had fired his automatic at them even as he was dying. Teddy found Davis lying on the ground with a bullet in his hip.

"I'm all right, Gerrod," said Davis cheerfully when Teddy went to him. "Just see if there are any more chaps in these houses before you bother with me."

Teddy explored the place thoroughly. There were many signs of human occupancy, but no one save Varrhus himself had been there when they landed. He returned to Davis to find him weakly trying to improvise a pad to stop the bleeding. Teddy lifted him and carried him to the house that seemed to be most used. In a little while Davis was quite comfortable and contented. He lit a cigarette and calmly began to read one of the newspapers that littered the place, while Teddy continued his explorations.

The landing field was a small one, no more than a hundred and fifty yards long by seventy-five wide. At one end was an unpretentious but comfortable dwelling, in one of whose rooms Davis was at that moment resting. At the other end a shed evidently formed the hangar for the black flyer. Along the sides of the inclosure were long sheds, some of them empty, some containing supplies of various sorts. Half a dozen cold bombs, complete except for the mysterious treatment of their surface that gave them their strange property, lay on the floor of one of the sheds along the sides. Another shed, long disused, had provided quarters for workmen. Teddy found the single exit that led from the inclosure. It opened on the wide hillside and afforded a view of miles without a sign of human habitation. The remnant of a wheel track that had obviously not been traveled for months led away from the door. Along that primitive road the materials for building the inclosure and the black flyer had evidently been brought. Teddy went back to Davis.

"Gerrod," said Davis amiably, "I'm a fake. I'd lost quite some blood, you know, and I was pretty weak, but while you were gone I saw a small black bottle on a shelf over there, and I managed to crawl over to it. Wherever we are, prohibition hasn't struck in, and I took just enough to feel all right again. I believe I can drive back. It wasn't more than a two-hour drive anyway, was it?'

"Between two and three," said Teddy, smiling. "We were making terrific speed, though. We're probably in Newfoundland somewhere."

"Or Iceland. To tell the truth, I'm
