his enthusiasm in check, “if you can come here⁠—I want you to check some math for me. I’ve done it⁠—and I want to see if you get the same result independently!” Morey was a more careful mathematician than he, and it was to him Arcot turned for verification of any new discovery.

Following the general directions Arcot gave him, Morey went through the long series of calculations⁠—and arrived at the same results. Slowly he looked up from the brief expression with which he had ended.

It was not the formula that astonished him⁠—it was its physical significance.

“Arcot⁠—do you think we can make it?”

There was a new expression in Arcot’s eyes, a tightness about his mouth.

“I hope so, Morey. If we don’t, Lanor is lost beyond a doubt⁠—and probably Earth is, too. Wade⁠—come here a minute, will you? Let Fuller take the controls, and tell him to push it. We have to get to work on this.”

Rapidly Arcot explained their calculations⁠—and the proof he had gotten.

“Our beam of molecular motion-controlling energy directs all molecular motion to go at right angles to it. The mechanism so far has been a field inside a coil really, but if these figures are right, it means that we can project that field to a considerable distance even in air. It’ll be a beam of power that will cause all molecules in its path to move at right angles to it, and in the direction we choose, by reversing the power in the projector. That means that no matter how big the thing is, we can tear it to pieces; we’ll use its own powers, its own energies, to rip it, or crush it.

“Imagine what would happen if we directed this against the side of a mountain⁠—the entire mass of rock would at once fly off at unimaginable speed, crashing ahead with terrific power, as all the molecules suddenly moved in the same direction. Nothing in all the Universe could hold together against it! It’s a disintegration ray of a sort⁠—a ray that will tear, or crush, for we can either make one half move away from the other⁠—or we can reverse the power, and make one half drive toward the other with all the terrific power of its molecules! It is omnipotent⁠—hmmm⁠—” Arcot paused, narrowing his eyes in thought.

“It has one limitation. Will it reach far in the air? In vacuum it should have an infinite range⁠—in the atmosphere all the molecules of the air will be affected, and it will cause a terrific blast of icy wind, a gale at temperatures far below zero! This will be even more effective here on Venus!

“But we must start designing the thing at once! Take some of the Immorpho and give me some, and we can let the sleep accumulate till we have more time! Look⁠—we’re in Sonor already! Land us, Fuller⁠—right where we were, and then come back here. We’re going to need you!”

The gorgeous display of a Venerian dawn was already coloring the east as the great buildings seemed to rise silently about them. The sky, which had been a dull luminous gray, a gray that rapidly grew brighter and brighter, was now like molten silver, through which were filtering the early rays of the intense sun. As the sun rose above the horizon, though invisible for clouds, it still was traceable by the wondrous shell pink that began to suffuse the ten mile layer of vapor. The tiny droplets were, however, breaking the clear light into a million rainbows, and all about the swiftly deepening pink were forming concentric circles of blue, of green, orange, and all the colors of the rainbow, repeated time after time⁠—a wondrous halo of glowing color, which only the doubly intense sun could create.

“It’s almost worth missing the sun all day to see their sunrises and sunsets,” Fuller commented. The men were watching it, despite their need for haste. It was a sight the like of which no Earthman had ever before seen.

Immediately, then, they plunged into the extremely complex calculation of the electrical apparatus to produce the necessary fields. To get the effect they wanted, they must have two separate fields of the director ray, and a third field of a slightly different nature, which would cause the director ray to move in one direction only. It would be disconcerting, to say the least, if the director ray, by some mistake, should turn upon them!

The work went on more swiftly than they had considered possible, but there was still much to be done on the theoretical end of the job alone when the streets about them began to fill. They noticed that a large crowd was assembling, and shortly after they had finished, after some of these people had stood there for more than an hour and a half, the crowd had grown to great size.

“From the looks of that collection, I should say we are about to become the principals in some kind of a celebration that we know nothing about. Well, we’re here, and in case they want us, we’re ready to come.”

The guard that always surrounded the Solarite had been doubled, and was maintaining a fairly large clear area about the ship.

Shortly thereafter they saw one of the high officials of Lanor come down the walk from the governmental building, walking toward the Solarite.

“Time for us to appear⁠—and it may as well be all of us this time. I’ll tell you what they say afterward, Wade. They’ve evidently gone to considerable trouble to get up this meeting, so let’s cooperate. I hate to slow up the work, but we’ll try to make it short.”

The four Terrestrians got into their cooling suits, and stepped outside the ship. The Lanorian dignitary left his guard, walked up to the quartet from Earth with measured tread, and halted before them.

“Earthmen,” he began in a deep, clear voice, “we have gathered here this morning to greet you and thank you for the tremendous service you have done us. Across the
