what then? Is their fire to be returned?"

      "If they make one single false move," said Colonel Boynton savagely, "give them everything you've got. And the 91st Squadron will be off the ground to support you at the first sign of trouble. We don't want to start anything, nor appear to do so. But, by the gods, Blake, this fellow means trouble eventually as sure as you're a flyer, and we won't wait for him to ask for it twice."

      They sat in silence, while the field outside became shrouded in night. And they speculated, as best they could from the few facts they had, as to what this might mean to the world, to their country, to themselves. It was an hour before Blake was aware of the fact that he was hungry.

      He rose to leave, but paused while Colonel Boynton answered the phone. The first startled exclamation held him rigid while he tried to piece together the officer's curt responses and guess at what was being told.

      "Colonel Boynton speaking… McGuire?.. Yes, Lieutenant… Over Mount Lawson?.. Yes – yes, the same ship, I've no doubt."

      His voice was even and cool in contrast to the excited tones that carried faintly to Blake standing by.

      "Quite right!" he said shortly. "You will remain where you are: act as observer: hold this line open and keep me informed. Captain Blake will leave immediately for observation. A squadron will follow. Let me know promptly what you see."

      He turned abruptly to the waiting man.

      "It is back!" he said. "We're in luck! Over the observatories at Mount Lawson; descending, so Lieutenant McGuire says. Take the same ship you had up to-day. Look them over – get up close – good luck!" He turned again to the phone.

      There were planes rolling from their hangars before Blake could reach his own ship. Their engines were thundering: men were rushing across the field, pulling on leather helmets and coats as they ran – all this while he warmed up his engine.

      A mechanic thrust in a package of sandwiches and a thermos of coffee while he waited. And Captain Blake grinned cheerfully and gulped the last of his food as he waved to the mechanics to pull out the wheel blocks. He opened the throttle and shot out into the dark.

      He climbed and circled the field, saw the waving motion of lights in red and green that marked the take-off of the planes of the 91st, and he straightened out on a course that in less than two hours would bring him over the heights of Mount Lawson and the mystery that awaited him there. And he fingered the trigger grip that was part of the stick and nodded within his dark cockpit at the rattle of a machine gun that merged its staccato notes with the engine's roar.

      But he felt, as he thought of that monster shape, as some primordial man might have felt, setting forth with a stone in his hand to wage war on a saurian beast.

      CHAPTER IV

      If Colonel Boynton could have stood with one of his lieutenants and Professor Sykes on a mountain top, he would have found, perhaps, the answer to his question. He had wondered in a puzzled fashion why the great ship had shown its mysterious presence over the flying field. He had questioned whether it was indeed the field that had been the object of their attention or whether in the cloudy murk they had merely wandered past. Could he have seen with the eyes of Lieutenant McGuire the descent of the great shape over Mount Lawson, he would have known beyond doubt that here was the magnet that drew the eyes of whatever crew was manning the big craft.

      It was dark where the two men stood. Others had come running at their call, but their forms, too, were lost in the shadows of the towering pines. The light from an open door struck across an open space beyond which McGuire and Professor Sykes stood alone, stood silent and spellbound, their heads craned back at a neck-wrenching angle. They were oblivious to all discomforts; their eyes and their whole minds were on the unbelievable thing in the sky.

      Beyond the fact that no lights were showing along the hull, there was no effort at concealment. The moon was up now to illumine the scene, and it showed plainly the gleaming cylinder with its long body and blunt, shining ends, dropping, slowly, inexorably down.

      "Like a dirigible," said McGuire huskily. "But the size, man – the size! And its shape is not right; it isn't streamlined correctly; the air – " He stopped his half-unconscious analysis abruptly. "The air!" What had this craft to do with the air? A thin layer of gas that hung close to the earth – the skin on an apple! And beyond – space! There was the ethereal ocean in which this great shape swam!

      The reality of the big ship, the very substance of it, made the space ship idea the harder to grasp. Lieutenant McGuire found that it was easier to see an imaginary craft taking off into space than to conceive of this monstrous shape, many hundreds of tons in weight, being thrown through vast emptiness. Yet he knew; he knew!

      And his mind was a chaos of grim threats and forebodings as he looked at the unbelievable reality and tried to picture what manner of men were watching, peering, from those rows of ports.

      At last it was motionless. It hung soundless and silent except for a soft roar, a scant thousand feet in the air. And its huge bulk was dwarfing the giant pines, the rounded buildings; it threw the men's familiar surroundings into a new and smaller scale.

      He had many times flown over these mountains, and Lieutenant McGuire had seen the silvery domes of the observatories shining among the trees. Like fortresses for aerial defense, he had thought, and the memory returned to him now. What did these new-comers think of them? Had they, too, found them suggestive of forts on the frontier of a world, defenses against invasion from out there? Or did they know them for what they were? Did they wish only to learn the extent of our knowledge, our culture? Were they friendly, perhaps? – half-timid and fearful of what they might find?

      A star moved in the sky, a pin-point of light that was plain in its message to the aviator. It was Blake, flying high, volplaning to make contact and learn from the air what this stranger might mean. The light of his plane slanted down in an easy descent; the flyer was gliding in on a long aerial toboggan slide. His motor was throttled; there was only the whistle of torn air on the monoplane's wings. McGuire was with the captain in his mind, and like him he was waiting for whatever the stranger might do.
