Anina met my eyes steadily.
"There is no other way," she said quietly. "It must be done. It is your world--your people--we must think of now. And you know there is no other way."
We decided at last to try it. Once we had made the decision, we proceeded as quickly as possible to put the plan into execution. We moved our encampment farther away, well out of danger from the fumes.
We mounted several of the projectors in positions where their rays could reach the surrounding country, and the sky, although not the city itself.
Then, ordering our men and girls to hold themselves in readiness for whatever might occur, we four went off together to fire the sulphur.
The wind was blowing directly toward the city as we stood at the base of the cliff, a silent little group. I think that now, at this moment, we all of us hesitated in awe at what we were about to do.
Mercer broke the tension.
"Come on, Alan--let"s start it off. Now is the time--a lot of places at once."
We flashed on our little light-rays, and in a moment the sulphur was on fire at a score of different points. We drew off a few hundred feet to one side and sat down to watch it in the darkness. Overhead Tao"s red beams swept like giant search-lights across the inky sky.
The sulphur started burning with tiny little spots of wavering blue flame that seemed, many of them, about to die away. Gradually they grew larger, spreading out slowly and silently in ever-widening circles. Under the heat of the flames the sulphur ma.s.ses became molten, turned into a viscous dark red fluid that boiled and bubbled heavily and dropped spluttering upon the ground.
Slowly the blue-green flames spread about, joining each other and making more rapid headway--a dozen tiny volcanoes vomiting their deadly fumes and pouring forth their sluggish, boiling lava. The scene about us now was lighted in a horrible blue-green glare. A great cloud of thin smoke gathered, hung poised a moment, and then rolled slowly away--its deadly fumes hanging low to the ground and spreading ever wider as though eager to clutch the unsuspecting city in their deadly embrace.
The entire face of the cliff was now covered with the crawling blue fire, lapping avidly about with its ten-foot tongues. We drew back, staring silently at each other"s ghastly green faces.
"Let"s--let"s get away," Mercer whispered finally. "No use staying here now."
We hurried back to the nearest place where one of our projectors was set up. The two men guarding it looked at us anxiously, and smiled triumphantly when Miela told them what we had done. We stood beside them a moment, then Miela and I climbed to an eminence near by from which we had an un.o.bstructed view of the city.
The light-barrage still held steady. The individual, higher-powered projectors as before swung their beams lazily about the country. We sat partly in the shelter of a huge bowlder, behind which we could have dropped quickly had one of them turned our way.
"Soon it will be there," Miela said softly, when we had been sitting quiet for a time.
I did not answer. It was indeed too solemn a thing for words, this watching from the darkness while an invisible death, let loose by our own hands, stole down upon our complacent enemies.
A few moments more we watched--and still the scene before us showed no change. Then, abruptly, the lights seemed to waver; some of the beams swung hurriedly to and fro, then remained motionless in unusual positions, as though the men at their levers in sudden panic had abandoned them.
My heart was beating violently. What hidden tragedy was being enacted behind that silent barrier of light? I shuddered as my imagination conjured up hideous pictures of that unseen death that now must be stalking about those city streets, entering those homes, polluting the air with its stifling, noisome breath, and that even at this distance seemed clutching at my own lungs.
I suppose the whole thing _did_ last only a moment. There was little in what we saw of significance had we not known. But we did know--and the knowledge left us trembling and unnerved.
I leaped to my feet, pulling Miela after me, and in a few moments more we were back beside the projector we had left with Mercer and Anina. Suddenly a white shape appeared in the sky over the city. It pa.s.sed perilously close above the shattered light-barrage and came sailing out in our direction.
Mercer jumped for the projector, but I was nearer, and in a moment I had flashed it on.
"It"s Tao!" Mercer shouted. "He--"
It was one of Tao"s interplanetary vehicles, rising slowly in a great arc above us. I swung our light-beams upward; it swept across the sky and fell upon the white shape; the thing seemed to poise in its flight, as though held by the little red circle of light that fastened upon it, boring its way in. Then, slowly at first, it fell; faster and faster it dropped, until it struck the ground with a great crash--the first and only sound of all this soundless warfare.
It was three days before the great sulphur deposit we had ignited burned itself out. The lights of the city had all died away, and blackness such as I never hope to experience again settled down upon the scene.
We approached the Dark City then; we even entered one or two of its outlying houses;, but beyond that we did not go, for we had made certain of what we wanted to know.
I remember my father once describing how, when a young man, he had gone to the little island of Martinique shortly after the great volcanic outbreak of Mount Pelee. I remember his reluctance to dwell upon the scenes he saw there in that silent city of St. Pierre--the houses with their dead occupants, stricken as they were sitting about the family table; the motionless forms in the streets, lying huddled where death had overtaken them in their sudden panic. That same reluctance silences me now, for one does not voluntarily dwell upon such scenes as those.
A day or so later we found the interplanetary projectile which had sought to escape. Amid its wreckage lay the single, broken form of Tao--that leader who, plotting the devastation of two worlds for his own personal gain, had at the very last deserted his comrades and met his death alone.
CHAPTER XXIX.
THE RETURN.
There is but little more to add. With the death of Tao and the changing of the law concerning the virgins" wings, my mission on Mercury was over. But I did not think of that then, for with the war ended, my position as virtual ruler of the Light Country still held Mercer and me occupied with a multiplicity of details. It was a month or more after our return from the Twilight Country that Miela reminded me of father and my duty to him.
"You have forgotten, my husband. But I have not. Your world--it calls you now. You must go back."
Go back home--to father and dear little Beth! I had not realized how much I had wanted it.
"What you have done for our nation--for our girls--can never be repaid, Alan. And you can do more in later years, perhaps. But now your father needs you--and we must think of him."
I cast aside every consideration of what changes would first have to be made here on Mercury, and decided in that moment to go.
"But you must go with me, Miela," I said, and then, as I thought of something else, I added gently: "You will, won"t you, little wife? For you know I cannot leave you now."
She smiled her tender little smile.
""Whither thou goest, I will go," my husband," she quoted softly, ""for thy people shall be my people, and thy G.o.d my G.o.d.""
We were ready to start at the time of the next inferior conjunction of Mercury with the earth. At our combined pleading, and with the permission of his a.s.sociates, Fuero was persuaded to take command of the nation during my absence; and I felt I was leaving affairs in able hands.
Lua refused to accompany us; but she urged Anina to go, and the little girl was ready enough to take advantage of her mother"s permission.
Though he said nothing, I shall never forget Mercer"s face as this decision was made.
The vehicle in which Miela had made her former trip was still lying in the valley where we had left it. We went away privately, only Lua and Fuero accompanying us out of the city.
Lua parted with her two daughters quietly. Her emotions at seeing them go she concealed under that sweet, gentle reserve which was characteristic of her always.
"Promise me you will be careful of her, Alan," she said softly as she kissed me at parting.
We landed in the Chilean Andes, with that patient statue of the Christ to welcome us back to earth. The Trans-Andean Railroad runs near it, and we soon were in the city of Buenos Aires. The two girls, with wings shrouded in their long cloaks, walked about its crowded streets with a wonderment I can only vaguely imagine. We had only what little money I had taken with me to Mercury. I interviewed a prominent banker of the city, told him in confidence who I was, and from him obtained necessary funds.
We cabled father then, and he answered at once that he would come down and join us. We waited for him down there, and in another month he was with us--dear old gentleman, leaning over the steamer rail, trying to hold back the tears of joy that sprang into his eyes at sight of me. Little Beth was with him, too, smart and stylish as ever, and good old Bob Trevor, whom she shyly presented as her husband.
The beach at Mar del Plata, near Buenos Aires, is one of the most beautiful spots in South America; and on a clear moonlit night, with the Southern Cross overhead, it displays the starry heavens as few other places can on this earth.
