The Boss had hardly finished his arrangements for the ring barrage, when one of the scouts on an eminence to the north, announced the approach of seven Han ships, spread out in a great semi-circle.

Hart leaped for the hillside, calling to us to do likewise, but Wilma and I had raised the flaps of our helmets and switched off our "speakers" for conversation between ourselves, and by the time we discovered what had happened, the ships were clearly visible, so fast were they approaching.

"Jump!" we heard the Boss order, "Deering to the north. Rogers to the east."

But Wilma looked at me meaningly and pointed to where the twisted plates of the ship, projecting from the ground, offered a shelter.

"Too late, Boss," she said. "They'd see us. Besides I think there's something here we ought to look at. It's probably their magnetic graph."

"You're signing your death warrant," Hart warned.

"We'll risk it," said Wilma and I together.

"Good for you," replied the Boss. "Take command then, Rogers, for the present. Do you all know his voice, boys?"

A chorus of a.s.sent rang in our ears, and I began to do some fast thinking as the girl and I ducked into the twisted ma.s.s of metal.

"Wilma, hunt for that record," I said, knowing that by the simple process of talking I could keep the entire command continuously informed as to the situation. "On the hillsides, keep your guns trained on the circles and stand by. On the hilltops, how many of you are there? Speak in rotation from Bald k.n.o.b around to the east, north, west."

In turn the men called their names. There were twenty of them.

I a.s.signed them by name to cover the various Han ships, numbering the latter from left to right.

"Train your rockets on their repellor rays about three-quarters of the way up, between ships and ground. Aim is more important than elevation.

Follow those rays with your aim continuously. Shoot when I tell you, not before. Deering has the record. The Hans probably have not seen us, or at least think there are but two of us in the valley, since they're settling without opening up disintegrators. Any opinions?"

My ear discs remained silent.

"Deering and I remain here until they land and debark. Stand by and keep alert."

Rapidly and easily the largest of the Han ships settled to the earth.

Three scouted sharply to the south, rising to a higher level. The others floated motionless about a thousand feet above.

Peeping through a small fissure between two plates, I saw the vast hulk of the ship come to rest full on the line of our prospective ring barrage. A door clanged open a couple of feet from the ground, and one by one the crew emerged.

CHAPTER VI

The "Wyoming Ma.s.sacre"

"They're coming out of the ship." I spoke quietly, with my hand over my mouth, for fear they might hear me. "One--two--three--four, five--six--seven--eight--nine. That seems to be all. Who knows how many men a ship like that is likely to carry?"

"About ten, if there are no pa.s.sengers," replied one of my men, probably one of those on the hillside.

"How are they armed?" I asked.

"Just knives," came the reply. "They never permit hand-rays on the ships. Afraid of accidents. Have a ruling against it."

"Leave them to us then," I said, for I had a hastily formed plan in my mind. "You, on the hillsides, take the ships above. Abandon the ring target. Divide up in training on those repellor rays. You, on the hilltops, all train on the repellors of the ships to the south. Shoot at the word, but not before.

"Wilma, crawl over to your left where you can make a straight leap for the door in that ship. These men are all walking around the wreck in a bunch. When they're on the far side, I'll give the word and you leap through that door in one bound. I'll follow. Maybe we won't be seen.

We'll overpower the guard inside, but don't shoot. We may escape being seen by both this crew and ships above. They can't see over this wreck."

It was so easy that it seemed too good to be true. The Hans who had emerged from the ship walked round the wreckage lazily, talking in guttural tones, keenly interested in the wreck, but quite unsuspicious.

At last they were on the far side. In a moment they would be picking their way into the wreck.

"Wilma, leap!" I almost whispered the order.

The distance between Wilma's hiding place and the door in the side of the Han ship was not more than fifteen feet. She was already crouched with her feet braced against a metal beam. Taking the lift of that wonderful inertron belt into her calculation, she dove headforemost, like a green projectile, through the door. I followed in a split second, more clumsily, but no less speedily, bruising my shoulder painfully, as I ricocheted from the edge of the opening and brought up sliding against the unconscious girl; for she evidently had hit her head against the part.i.tion within the ship into which she had crashed.

We had made some noise within the ship. Shuffling footsteps were approaching down a well lit gangway.

"Any signs we have been observed?" I asked my men on the hillsides.

"Not yet," I heard the Boss reply. "Ships overhead still standing. No beams have been broken out. Men on ground absorbed in wreck. Most of them have crawled into it out of sight."

"Good," I said quickly. "Deering hit her head. Knocked out. One or more members of the crew approaching. We're not discovered yet. I'll take care of them. Stand a bit longer, but be ready."

I think my last words must have been heard by the man who was approaching, for he stopped suddenly.

I crouched at the far side of the compartment, motionless. I would not draw my sword if there were only one of them. He would be a weakling, I figured, and I should easily overcome him with my bare hands.

Apparently rea.s.sured at the absence of any further sound, a man came around a sort of bulkhead--and I leaped.

I swung my legs up in front of me as I did so, catching him full in the stomach and knocked him cold.

I ran forward along the keel gangway, searching for the control room. I found it well up in the nose of the ship. And it was deserted. What could I do to jam the controls of the ships that would not register on the recording instruments of the other ships? I gazed at the ma.s.s of controls. Levers and wheels galore. In the center of the compartment, on a ma.s.sively braced universal joint mounting, was what I took for the repellor generator. A dial on it glowed and a faint hum came from within its shielding metallic case. But I had no time to study it.

Above all else, I was afraid that some automatic telephone apparatus existed in the room, through which I might be heard on the other ships.

The risk of trying to jam the controls was too great. I abandoned the idea and withdrew softly. I would have to take a chance that there was no other member of the crew aboard.

I ran back to the entrance compartment. Wilma still lay where she had slumped down. I heard the voices of the Hans approaching. It was time to act. The next few seconds would tell whether the ships in the air would try or be able to melt us into nothingness. I spoke.

"Are you boys all ready?" I asked, creeping to a position opposite the door and drawing my hand-gun.

Again there was a chorus of a.s.sent.

"Then on the count of three, shoot up those repellor rays--all of them--and for G.o.d's sake, don't miss." And I counted.

I think my "three" was a bit weak. I know it took all the courage I had to utter it.

For an agonizing instant nothing happened, except that the landing party from the ship strolled into my range of vision.

Then startled, they turned their eyes upward. For an instant they stood frozen with horror at whatever they saw.
