They learned how to make engines that emitted beams of destruction and transmutation; and how to employ these unknown beams, more potent even than the so-called “cosmic rays,” in the renewal of human tissues and the conquest of disease and old age.

Simultaneously with this tuition, the plant-lord carried on the building of a new space-car, in which the earth-men were to return to their own planet and preach the Martian evangel. The construction of this car, whose plates and girders seemed to materialize out of the void air before their very gaze, was a practical lesson in the use of arcanic natural forces. Atoms that would form the requisite alloys were brought together from space by the play of invisible magnetic beams, were fused by concentrated solar heat in a specially refractive zone of atmosphere, and were then moulded into the desired form as readily as the bottle that shapes itself from the pipe of the glass-blower.

Equipped with this new knowledge and potential masterdom, with a cargo of astounding mechanisms and devices made for their use by the plant-lord, the pro-Martians finally embarked on their earthward voyage.

A week after the abduction of the thirty-five earth-men from the stadium at Berkeley, the space-car containing the Martian’s proselytes landed at noon in this same stadium. Beneath the infinitely skilful and easy control of the far-off plant-being, it came down without accident, lightly as a bird; and as soon as the news of its arrival had spread, it was surrounded by a great throng, in which the motives of hostility and curiosity were almost equally paramount.

Through the denunciation of the dogmatists led by Stilton, the savants and the three reporters beneath the leadership of Gaillard had been internationally outlawed before their arrival. It was expected that they would return sooner or later through the machinations of the plant-lord; and a special ruling that forbade them to land on terrene soil, under penalty of imprisonment, had been made by all the Governments.

Ignorant of this, and ignorant also of how wide-spread and virulent was the prejudice against them, they opened the vessel’s port and stood in readiness to emerge.

Gaillard, going first, paused at the head of the metal stairway, and something seemed to arrest him as he looked down on the milling faces of the mob that had gathered with incredible swiftness. He saw enmity, fear, hatred, suspicion, in many of these faces; and in others a gaping and zany-like inquisitiveness, such as might be shown before the freaks of some travelling circus. A small corps of policemen, elbowing and thrusting the rabble aside with officious rudeness, was pushing toward the front; and cries of derision and hatred, gathering by two and threes and uniting to a rough roar, were now hurled at the occupants of the car.

“Damn the pro-Martians! Down with the dirty traitors! Hang the– – –dogs!”

An overripe tomato, large and dripping, sailed toward Gaillard and splashed on the steps at his feet. Hisses and hoots and cat-calls added to the roaring bedlam, but above it all, he and his comrades heard a quiet voice that spoke within the car; the voice of the Martian, borne across inestimable miles of ether:

“Beware, and defer your landing. Resign yourselves to my guidance, and all will be well.”

Gaillard stepped back as he heard this minatory voice, and the valvular port closed quickly behind the folded stairs, just as the policemen who had come to arrest the vessel’s occupants broke from the forefront of the throng.

Peering out on those hateful faces, Gaillard and his brother-savants beheld an astounding manifestation of the Martian’s power. A wall of violet flame, descending from the remote heavens to the ground, seemed to intervene between the car and the crowd, and the policemen, bruised and breathless but uninjured, were hurled backward as if by a great wave. This flame, whose color changed to blue and green and yellow and scarlet like a sort of aurora, played for hours about the vessel and rendered it impossible for anyone to approach. Retreating to a respectful distance, awe-struck and terrified, the crowd looked on in silence; and the police waited in vain for a chance to fulfill their commission. After awhile, the flame became white and misty, and upon it, as upon the bosom of a cloud, a bizarre and mirage-like scene was imprinted, visible alike to the occupants of the car and the throng without. This scene was the Martian landscape in which the central brain of the plant-lord was located; and the crowd gasped with astonishment as it met the gaze of the enormous telescopic eyes, and saw the unending stems and league-wide masses of sempervirent foliage.

Other scenes and demonstrations followed, all of which were calculated to impress upon the throng the wonder-working powers and marvellous faculties of this remote being.

Pictures that illustrated the historic life of the Martian, as well as the various arcanic natural energies subject to its dominion, followed each other in rapid succession. The purpose of the desired alliance with Earth, and the benefits which would accrue thereby to humanity, were also depicted. The divine benignity and wisdom of this puissant being, its superior organic nature, and its vital and scientific supremacy, were made plain to the dullest observer.

Many of those who had come to scoff, or had been prepared to receive the pro-Martians and their evangel with scorn and hate and violence, became converted to the alien cause forthwith by these sublime demonstrations.

However, the more dogmatic scientists, the true “die-hards” as represented by Godfrey Stilton, maintained an adamantine obstructionism, in which they were supported by the officers of law and government, as well as by the presbyters of the various religions. The world-wide dissidence of opinion which soon resulted, became the cause of many civil wars or revolutions, and, in one or two cases, ended in actual warfare between nations.

Numerous efforts were made to apprehend or destroy the Martian space-car, which, beneath the guidance of its ultra-planetary master, appeared in many localities all over the world, descending suddenly from the stratosphere to perform incredible scientific miracles before the eyes of astonished multitudes. In all quarters of the globe, the mirage-like pictures were flashed on the screen of cloudy fire, and more and more people went over to the new cause.

Bombing planes pursued the vessel and sought to drop their deadly freight upon it, but without success; for whenever the car was endangered, the auroral flames intervened, deflecting and hurling back the exploded bombs, often to the detriment of their launchers.

Gaillard and his confreres, with leonine boldness, emerged many times from the car, to display before crowds or selected bodies of savants the marvellous inventions and chemical thaumaturgies with which they had been endowed by the Martian. Everywhere the police sought to arrest them, maddened mobs endeavored to do them violence, armed regiments tried to surround them and cut them off from the car. But with an adroitness that seemed no less than supernatural, they contrived always to elude capture; and often they discomfited their pursuers by astonishing displays or evocations of esoteric force, temporarily paralyzing the civic officers with unseen rays, or creating about themselves a defensive zone of intolerable heat or trans-arctic cold.

In spite of all these myriad demonstrations, however, the citadels of human ignorance and insularity remained impregnable in many places. Deeply alarmed by this ultra-terrene menace to their stability, the governments and religions of Earth, as well as the more conservative scientific elements, rallied their resources in a most heroic and determined effort to stem the incursion. Men of all ages, everywhere, were conscripted for service in the national armies; and even women and children were equipped with the deadliest weapons of the age for use against the pro-Martians, who, with their wives and families, were classed as infamous renegades to be hunted down and killed without ceremony like dangerous beasts.
