“Something like that, possibly.”
The extraordinary skill of the Kofedix made the manufacture of the instruments a short task, and after Crane had replaced the few broken instruments of the Skylark from their reserve stock, they turned their attention to the supply of copper that had been gathered. They found it enough for only two bars.
“Is this all we have?” asked Dunark, sharply.
“It is, your Highness,” replied the Kolanix. “That is every scrap of metallic copper in the city.”
“Oh, well, that’ll be enough to last until we can smelt the rest,” said Seaton. “With one bar apiece we’re ready for anything Mardonale can start. Let ’em come!”
The bars were placed in the containers and both vessels were tried out, each making a perfect performance. Upon the following kokam, immediately after the first meal, the full party from the Earth boarded the Skylark and accompanied the Kofedix to the copper smelter. Dunark himself directed the work of preparing the charges and the molds, though he was continually being interrupted by wireless messages in code and by messengers bearing tidings too important to trust into the air.
“I hope you will excuse all of these delays,” said Dunark, after the twentieth interruption, “but …”
“That’s all right, Dunark. We know that you’re a busy man.”
“I can tell you about it, but I wouldn’t want to tell many people. With the salt you gave us, I am preparing a power-plant that will enable us to blow Mardonale into …”
He broke off as a wireless call for help sounded. All listened intently, learning that a freight-plane was being pursued by a karlon a few hundred miles away.
“Now’s the time for you to study one, Dunark!” Seaton exclaimed. “Get your gang of scientists out here while we go get him and drag him in!”
As Dunark sent the message, the Skylark’s people hurried aboard, and Seaton drove the vessel toward the calls for help. With its great speed it reached the monster before the plane was overtaken. Focusing the attractor upon the enormous metallic beak of the karlon, Seaton threw on the power and the beast halted in midair as it was jerked backward and upward. As it saw the puny size of the attacking Skylark, it opened its cavernous mouth in a horrible roar and rushed at full speed. Seaton, unwilling to have the repellers stripped from the vessel, turned on the current actuating them. The karlon was hurled backward to the point of equilibrium of the two forces, where it struggled demoniacally.
Seaton carried his captive back to the smelter, where finally, by judicious pushing and pulling, he succeeded in turning the monster flat upon its back and pinning it to the ground in spite of its struggles to escape.
Soon the scientists arrived and studied the animal thoroughly, at as close a range as its flailing arms permitted.
“I wish we could kill him without blowing him to bits,” wirelessed Dunark. “Do you know any way of doing it?”
“We could if we had a few barrels of ether, or some of our own poison gases, but they are all unknown here and it would take a long time to build the apparatus to make them. I’ll see if I can’t tire him out and get him that way as soon as you’ve studied him enough. We may be able to find out where he lives, too.”
The scientists having finished their observations, Seaton jerked the animal a few miles into the air and shut off the forces acting upon it. There was a sudden crash, and the karlon, knowing that this apparently insignificant vessel was its master, turned in headlong flight.
“Have you any idea what caused the noise just then, Dick?” asked Crane; who, with characteristic imperturbability, had taken out his notebook and was making exact notes of all that transpired.
“I imagine we cracked a few of his plates,” replied Seaton with a laugh, as he held the Skylark in place a few hundred feet above the fleeing animal.
Pitted for the first time in its life against an antagonist, who could both outfly and outfight it, the karlon redoubled its efforts and fled in a panic of fear. It flew back over the city of Kondalek, over the outlying country, and out over the ocean, still followed easily by the Skylark. As they neared the Mardonalian border, a fleet of warships rose to contest the entry of the monster. Seaton, not wishing to let the foe see the rejuvenated Skylark, jerked his captive high into the thin air. As soon as it was released, it headed for the ocean in an almost perpendicular dive, while Seaton focused an object-compass upon it.
“Go to it, old top,” he addressed the plunging monster. “We’ll follow you clear to the bottom of the ocean if you go that far!”
There was a mighty double splash as the karlon struck the water, closely followed by the Skylark. The girls gasped as the vessel plunged below the surface at such terrific speed, and seemed surprised that it had suffered no injury and that they had felt no jar. Seaton turned on the powerful searchlights and kept close enough so that he could see the monster through the transparent walls. Deeper and deeper the quarry dove, until it was plainly evident to the pursuers that it was just as much at home in the water as it was in the air. The beams of the lights revealed strange forms of life, among which were huge, staring-eyed fishes, which floundered about blindly in the unaccustomed glare. As the karlon bored still deeper, the living things became scarcer, but still occasional fleeting glimpses were obtained of the living nightmares which inhabited the oppressive depths of these strange seas. Continuing downward, the karlon plumbed the nethermost pit of the ocean and came to rest upon the bottom, stirring up a murk of ooze.
“How deep are we, Mart?”
“About four miles. I have
