Gradually the form died out and was replaced by others.

"The forms which you call insects on your Earth were more primitive and hardier forms and more readily adaptable. They increased in size and in intelligence until they were ready to supplant all other forms. The last vestiges of the bipeds were carefully nurtured and guarded by our forefathers until the vanishing atmosphere made their survival impossible. The insect form became supreme.

"We multiplied with extreme rapidity and would have overcrowded the planet had we not learned several things. Our present form of life is immature in many ways. For example, we are totally unable to reproduce our kind. That is the function of the next phase. In this form, however, the intelligence reaches its maximum. As a result, all living creatures, except selected ones, have their growth arrested at the larval stage and pa.s.s their entire life in this form. Certain ones at long intervals of time as the population diminishes, are allowed to spin coc.o.o.ns and hatch out in the form you have witnessed. This form is almost brainless, the securing of nourishment from flowers and reproducing their kind being the limits of their intelligence. The eggs are maturing in the body of the one you saw. Soon she will lay many thousands of them and then, her life mission accomplished, she will die. We will gather these eggs and tend them until they hatch. All defective ones will be destroyed and the balance will be instructed until they are ready to take their place in the community and carry on the work of the planet."

"That is extremely interesting," exclaimed Damis. "Will our Earth in time support the same forms of life as does Mars now?"

"I can see no reason why evolution should follow a different path there than it has here," replied Attomanis, "but millions of years will pa.s.s before you lose your atmosphere to such an extent as we have. All of our water is gathered at the polar icecaps, from whence we lead it as it melts through underground pipes hundreds of miles to the spot where we desire vegetation to grow. There we deliver it directly to the roots of the plants so there is no waste. Great bands of cultivated areas crisscross the planet where the soil is of unusual fertility. A certain number of plants are allowed to flower and to bear fruit for the sustenance of the reproductive form of life and to replace themselves.

The others we devour while they are young and tender."

"Do you always live in these sealed cities?"

"Always. There are hundreds of them scattered over the planet. As you have noticed, they are composed of damazonium, the same substance as is used in making the transporters. The whole city is but a large transporter. When we desire to feed, the city is disintegrated and materialized over a patch of vegetation which we eat. When the supply is for a time exhausted, the city is moved. This is one way in which we conserve the small supply of atmosphere which is left."

Attomanis suddenly paused and held up one hand for silence. In a moment the thought waves again beat in on the consciousness of Damis and Turgan.

"The weapons which were promised you are ready," he said. "We will return to the throne of the Grand Mognac and you will receive instructions in their use."

He again mounted the platform and Damis and Turgan took their places beside him. Rapidly they were borne over the ground until they came to a stop before the dais on which the Grand Mognac rested. Beside the four cylinders in which they and the Grand Mognac's messengers had traveled from the s.p.a.ce ship to the city, another of huge proportions stood before the platform. Beside it were two instruments. From a ma.s.s of coils and tubes a long rod projected up. It was pivoted so that it could be directed toward any point. The rod on one of the instruments was blue while the other was a fiery scarlet.

"These are the weapons which will enable you to destroy your oppressors and prevent more from ever landing," said the Grand Mognac. "I must caution you, however, regarding their use. They generate a ray of almost infinite frequency, much higher than the disintegrating ray the Jovians use. Instead of resolving materials into light and energy, these devices will absolutely destroy the ether, that imponderable substance which permeates and fills all s.p.a.ce.

"Heat and light travel in waves through the ether. When it is destroyed, only blackness and entire absence of heat remain. Nothing can bear the cold of interstellar s.p.a.ce and yet it is warm compared to the absolute cold which the absence of ether produces. When you direct one of these rays toward a Jovian ship, the ether in the ship is destroyed. No insulation against the cold of s.p.a.ce will interfere for the ether penetrates and permeates all substance. The cold of absolute nothingness will destroy all life in the twinkling of an eye and the ship will be reduced to a puff of powder. At such a temperature, even stellanium has less strength than the most brittle substance.

"There are two of these devices, set to different powers. The one with the blue rod is for use against s.p.a.ce ships either before or after they enter the atmosphere envelope. Beware of using it except when it points in a direction almost normal to the surface of your planet. These devices tap and use the enormous force of gravity itself and when they are locked to your planet, they are anch.o.r.ed to the center of gravity of the planet. Unless it were normal to the planet's surface, its reactive force is so great that it would disrupt the balance which holds the planet in place were the beam sent off on a tangential line.

"The other, whose projecting rod is painted red, can be used at any angle as its force is only a minute fraction of that of the other. It also must be locked to the center of gravity of the earth before it is used by means of the switch on the front. This instrument will give you power to annihilate your oppressors on earth, for while it has not the terrible force of the other, it will penetrate any protective screen which the science of Jupiter can erect. Use it only against the Jovians and when you have finished with it, destroy it that it may not fall into the hands of those who would misuse it. The other may be left intact to repel other Jovian attacks but I think you need fear none. Once they learn you have it, they will be content with their conquests of Venus and Mercury and give you a wide berth. The Jovians have had a taste of it already and they leave Mars alone. Each instrument is set in action by closing the switch on top, after closing the gravity anchor switch.

To stop them, open the top switch."

Under the direction of the Grand Mognac, the Martians placed the terrible weapons in the transporter prepared for them. Turgan and Damis strove to thank the Grand Mognac for his gift but he interrupted them promptly.

"No thanks are due us," he said. "We have done that which we believe is the best for the orderly development of this galaxy of planets and there is no reason why we should be thanked. Now enter the transporters and you will be returned to your s.p.a.ce ship. Destroy your oppressors and work for the day when Mars and Earth will march in peace toward the final goal of all life."

Accompanied by two Martian envoys, Damis and Turgan entered the cylinders and fastened them closely. They set their feet in place and grasped the handles before them. Again came the feeling of nausea and then a thought ordered them to emerge from the transporters. They emerged almost at the same instant. Before them lay the s.p.a.ce ship with its airlock wide open. Not a living soul was in sight. Damis leaped toward the ship, but his foot struck an obstruction which sent him sprawling. He glanced down and a hoa.r.s.e cry of alarm broke from his lips. He had stumbled over the body of Kastner. The body had been horribly mutilated by some heavy instrument, one arm hanging to the torso by a mere shred of flesh. Scattered around on the ground lay other mutilated bodies.

With a shout of anguish, Turgan sped toward the open s.p.a.ce ship. Damis, with a pale face, hastily examined the dead bodies. Eighteen of the Terrestrials lay stiff in death while the bodies of two huge Jovians in the uniform of Glavour's personal guard told the cause of their death.

Damis struck by a sudden apprehension, ran from one body to the next, and in a little while he straightened up with a momentary breath of relief. Lura's body was not among them. He turned to the s.p.a.ce ship in time to see Turgan appear in the door of the airlock, his face distorted by grief and his tall body swaying. Damis hurriedly ran to him.

"Is Lura--dead?"

He brought out the last word with an effort. Turgan's face worked for a moment before he could reply. Through the thin air of Mars came his choking voice.

"Worse," he muttered: "she is gone!"

[Ill.u.s.tration: Damis' fist caught him under the ear.]

CHAPTER IV

_Damis' Decision_

Damis stared at Turgan for a moment as though unable to comprehend the old man's words.

"Gone?" he repeated stupidly. "She has slain herself?"

"No," replied the Kildare, his face still working in grief; "she is gone from us. She has been captured by Glavour's minions."

"Her dagger--?" asked Damis hesitatingly.

"Is gone with her," replied Turgan.

The Nepthalim started toward the s.p.a.ce ship but a thought wave from one of the Martian envoys stopped him in mid-stride.

"Wait, Man of Earth," came the message. "The heavens are eternally watched by our people and none can enter or leave the vicinity of Mars unknown to us. My comrade is now inquiring of each of the observers whence came the Jovians and where they have gone."

Turgan and Damis waited impatiently. Presently the second Martian sent a thought wave to their minds.

"The Jovian ship approached Mars using Phobus, one of our moons, as a screen to its movements. It was close to the planet before it was seen.

When challenged, the ship sent a message saying that it was captained by Toness, an Akildare of Earth and an enemy of the Jovians. The Grand Mognac was engaged and the matter was referred to the Mozar of Chinamonot, the nearest city. Thinking they were your followers, he directed them to land here. The Grand Mognac is enraged beyond measure that, after so many ages of failure, the Jovians have made a successful raid on our planet. The Mozar will pay for his indiscretion with his life."

A groan burst from Turgan's lips. Damis stood for a moment stricken with grief, and then sprang in giant leaps toward the s.p.a.ce flyer.

"Come, Turgan!" he cried. "We may overtake them yet. At least we can avenge if we cannot save."

The Kildare followed him more slowly.

"Where, oh, Nepthalim," he asked, "will we find them in the trackless wastes of s.p.a.ce?"

Damis paused at the words.

"Why, between here and Earth," he replied. As he did so a thought crossed his mind which was revealed by the sudden expression of dismay which clouded his features. "Earth, Venus, Mercury, Moon, Jupiter--all are under the rule of the Sons of G.o.d," he cried.

"And to any of them, Glavour's ship may have fled," replied the Kildare.

"Before we start in pursuit, it is best to find, if we can, in what direction the ship went."
