The captain arose smartly, but his words came with less ease.
"My opinion," he stated, "will be of little value, but it is based upon these facts. I have seen to-night, sir, a new type of aircraft, with speed, climb and ceiling beyond anything we are capable of. I can only regard it as a menace. It may or may not have been armed, but it had the size to permit the armament of a cruiser; it had power to carry that weight. It hung stationary in the air, so it is independent of wing-lift, yet it turned and shot upward like a feather in a gale. That spells maneuverability.
"That combination, sir, can mean only that we are out-flown, out-maneuvered and out-fought in the air. It means that the planes in our hangars are obsolete, our armament so much old iron.
"The menace is potential at present. Whether it is an actual threat or not is another matter. Who mans that ship – what country's insignia she carries – is something on which I can have no opinion. The power is there: who wields it I wish we knew."
The questioner nodded at the conclusion of Blake's words, and he exchanged quiet, grave glances with the general beside him. Then —
"I think we all would wish to know that, Captain Blake," he observed. And to the colonel: "You may be able to answer that soon. It would be my idea that this craft should be – ah – drawn out, if we can do it. We would not attack it, of course, until its mission is proved definitely unfriendly, but you will resist any offensive from them.
"And now," he added, "let us thank these officers for their able reports and excuse them. We have much to discuss…"
Captain Blake took McGuire's arm as they went out into the night. And he drew him away where they walked for silent minutes by themselves. The eyes of Lieutenant McGuire roamed upward to the scudding clouds and the glimpse of far, lonely stars; he stumbled occasionally as he walked. But for Captain Blake there was thought only of matters nearby.
"The old fox!" he exclaimed. "Didn't he 'sic us on' neatly? If we mix it with that stranger there will be no censure from the Secretary of War."
"I assumed that was who it was," said McGuire. "Well, they have something to think about, that bunch; something to study over… Perhaps more than they know.
"And that's their job," he concluded after a silence. "I'm going to bed; but I would like a leave of absence to-morrow if that's O. K."
"Sure," said Captain Blake, "though I should think you would like to stick around. Perhaps we will see something. What's on your mind, Mac?"
"A little drive to the top of Mount Lawson," said Lieutenant McGuire. "I want to talk to a bird named Sykes."
CHAPTER II
Lieutenant McGuire, U. S. A., was not given as a usual thing to vain conjectures, nor did his imagination carry him beyond the practical boundaries of accepted facts. Yet his mind, as he drove for hours through the orange-scented hills of California, reverted time and again to one persistent thought. And it was with him still, even when he was consciously concentrating on the hairpin turns of Mount Lawson's narrow road.
There was a picture there, printed indelibly in his mind – a picture of a monstrous craft, a liner of the air, that swung its glowing lights in a swift arc and, like a projectile from some huge gun, shot up and up and still up until it vanished in a jet-black sky. Its altitude when it passed from sight he could not even guess, but the sense of ever-increasing speed, of power that mocked at gravitation's puny force, had struck deep into his mind. And McGuire saw plainly this mystery ship going on and on far into the empty night where man had never been.
No lagging in that swift flight that he had seen; an acceleration that threw the ship faster and yet faster, regardless of the thin air and the lessened buoyancy in an ocean of atmosphere that held man-made machines so close to Earth. That constant acceleration, hour after hour, day after day – the speed would be almost unlimited; inconceivable!
He stopped his car where the mountain road held straight for a hundred feet, and he looked out over the coastal plain spread like a toy world far below.
"Now, how about it?" he asked himself. "Blake thinks I am making a fool of myself. Perhaps I am. I wonder. It's a long time since I fell for any fairy stories. But this thing has got me. A sort of hunch, I guess."
The sun was shining now from a vault of clear blue. It was lighting a world of reality, of houses where people lived their commonplace lives, tiny houses squared off in blocks a mile below. There was smoke here and there from factories; it spread in a haze, and it meant boilers and engines and sound practical machinery of a practical world to the watching man.
What had all this to do with Venus? he asked himself. This was the world he knew. It was real; space was impenetrable; there were no men or beings of any sort that could travel through space. Blake was right: he was on a fool's errand. They couldn't tell him anything up here at the observatory; they would laugh at him as he deserved…
Wondering vaguely if there was a place to turn around, he looked ahead and then up; his eyes passed from the gash of roadway on the mountainside to the deep blue beyond. And within the man some driving, insistent, mental force etched strongly before his eyes that picture and its problem unanswered. There was the ship – he saw it in memory – and it went up and still up; and he knew as surely as if he had guided the craft that the meteor-like flight could be endless.
Lieutenant McGuire could not reason it out – such power was beyond his imagining – but suddenly he dared to believe, and he knew it was true.
"Earthbound!" he said in contempt of his own human kind, and he looked again at the map spread below. "Ants! Mites! That's what we are – swarming across the surface of the globe. And we think we're so damn clever if we lift ourselves up a few miles from the surface!
"Guess I'll see Sykes," he muttered aloud. "He and his kind at least dare to look out into space; take their eyes off the world; be impractical!"
He swung the car slowly around the curve ahead, eased noiselessly into second gear and went on with the climb.
There were domed observatories where he stopped: rounded structures that gleamed silvery in the air; and offices, laboratories: it was a place of busy men. And Professor Sykes, he found, was busy. But he spared a few minutes to answer courteously the questions of this slim young fellow in the khaki uniform of the air service.
"What can I do for you?" asked Professor Sykes.
"No dreamer, this man," thought McGuire as he looked at the short, stocky figure of the scientist. Clear eyes glanced sharply from under shaggy brows; there were papers in his hand scrawled over with strange mathematical symbols.
"You can answer some fool questions," said Lieutenant McGuire abruptly, "if you don't mind."
The scientist smiled broadly. "We're used to that," he told the young officer; "you can't think of any worse ones than those we have heard. Have a chair."
McGuire drew a clipping from his pocket – it was the newspaper account he had read – and he handed it to Professor Sykes.
"I came to see you about this," he began.
The lips of Professor Sykes lost their genial curve; they straightened to a hard line. "Nothing for publication," he said curtly. "As usual they enlarged upon the report and made assumptions and inferences not warranted by facts."
"But you did see that flash?"
"By visual observation I saw a bright area formed on the terminator – yes! We have no photographic corroboration."
"I am wondering what it meant."
"That is your privilege – and mine," said the scientist coldly.
"But it said there," McGuire persisted, "that it might have been a signal of some sort."
"I did not say so: that is an inference only. I have told you, Lieutenant" – he glanced
