"It's suah trouble, all right," went on Eradicate."Mah mule, Boomerang, had a touch ob de colic, an' I got up t' gib him some hot drops an' walk him around, when I heard de mostest terrific racket-sound, and den I 'spected trouble was comm.""It isn't coming--it's here!" called Tom, as he sped toward the big shop.Ned was but a step behind him.The big workshop where the aerial warship was being built was, like the other buildings, brilliantly illuminated by the lights Tom had switched on.The young inventor also saw several of his employees speeding toward the same point.
Torn was the first to reach the small door of the shed.This was built in one of the two large main doors, which could be swung open when it was desired to slide the Mars in from the ground, and not admit it through the roof.
"Look!" cried Tom, pointing.
Ned looked over his chum's shoulder and saw the giant, Koku, struggling with four men--powerful men they were, too, and they seemed bent on mischief.
For they came at Koku from four sides, seeking to hold his hands and feet so that he could not fight them back.On the floor near where the struggle was taking place was a coil of rope, and it was evident that it had been the intention of the men to overcome Koku and truss him up, so that he would not interfere with what they intended to do.But Koku was a match for even the four men, powerful as they were.
"We're here, Koku!" cried Tom."Watch for an opening, Ned!" he called to his chum.
The sound of Tom's voice disconcerted at least two of the attackers, for they looked around quickly, and this was fatal to their chances.
Though such a big man, Koku was exceptionally quick, and no sooner did he see his advantage, as two of the men turned their gaze away from him, than he seized it.
Suddenly tearing loose his hands from the grip of the two men who had looked around, Koku shot out his right and left fists, and secured good hold on the necks of two of his enemies.The other two, at his back, were endeavoring to pull him over, but the giant's sturdy legs still held.
So big was Koku's hands that they almost encircled the necks of his antagonists.Then happened a curious thing.
With a shout that might have done credit to some ancient cave- dweller of the stone age, Koku spread out his mighty arms, and held apart the two men he had grasped.In vain they struggled to free themselves from that terrible grip.Their faces turned purple, and their eyes bulged out.
"He's choking them to death!" shouted Ned.But Koku was not needlessly cruel.
A moment later, with a quick and sudden motion he bent his arms, bringing toward each other the two men he held as captives.Their heads came together with a dull thud, and a second later Koku allowed two limp bodies to slip from his grip to the floor.
"He's done for them!" Tom cried."Knocked them unconscious.Good for you, Koku!"The giant grunted, and then, with a quick motion, slung himself around, hoping to bring the enemies at his back within reach of his powerful arms.But there was no need of this.
As soon as the other two ruffians had seen their companions fall to the floor of the shop they turned and fled, leaping from an open window.
"There they go!" cried Ned.
"Some of the other men can chase them," said the young inventor."We'll tie up the two Koku has captured." As he approached nearer to the unconscious captives Tom uttered a cry of surprise, for he recognized them as two of the new men he had employed.
"What can this mean?" he asked wonderingly.
He glanced toward the window through which the two men had jumped to escape, and he was just in time to see one of them run past the open door.The face of this one was under a powerful electric light, and Tom at once recognized the man as Feldman, the worker who had had so much trouble with the trip-hammer.
"This sure is a puzzle," marveled Tom."My own men in the plot! But why did they attack Koku?"The giant, bending over the men he had knocked unconscious by beating their heads together, seemed little worse for the attack.
"We tie 'em up," he said grimly, as he brought over the rope that had been intended for himself.
