"Dunark!... Coming out, heading directly for 'X'.... No, better stay quite a ways off to one side when we get going good.... Yes, I'm accelerating twenty six point oh oh oh.... Yes. I'll call you now and then, until the radio waves get lost, to check the course with you.

After that, keep on the last course, reverse at the calculated distance, and by the time we're pretty well slowed down, we'll feel around for each other with the compa.s.ses and go in together.... Right....

Uh-huh.... Fine! So long!"

In order that the two vessels should keep reasonably close together, it had been agreed that each should be held at an acceleration of exactly twenty-six feet per second, positive and negative. This figure represented a compromise between the gravitational forces of the two worlds upon which the different parties lived. While considerably less than the acceleration of gravitation at the surface of the Earth, the Terrestrials could readily accustom themselves to it; and it was not enough greater than that of Osnome to hamper seriously the activities of the green people.

Well clear of the Earth's influence, Seaton a.s.sured himself that everything was functioning properly, then stretched to his full height, wreathed his arms over his head, and heaved a deep sigh of relief.

"Folks," he declared, "This is the first time I've felt right since we got out of this old bottle. Why, I feel so good a cat could walk up to me and scratch me right in the eye, and I wouldn't even scratch back.

Yowp! I'm a wild Siberian catamount, and this is my night to howl.

Whee-ee-yerow!"

Dorothy laughed, a gay, lilting carol.

"Haven't I always told you he had cat blood in him, Peggy? Just like all tomcats, every once in a while he has to stretch his claws and yowl. But go ahead, d.i.c.kie, I like it--this is the first uproar you've made in weeks. I believe I'll join you!"

"It most certainly is a relief to get this load off our minds: I could do a little ladylike yowling myself," Margaret said; and Crane, lying completely at ease, a thin spiral of smoke curling upward from his cigarette, nodded agreement.

"d.i.c.k's yowling is quite expressive at times. All of us feel the same way, but some of us are unable to express ourselves quite so vividly.

However, it is past bedtime, and we should organize our crew. Shall we do it as we did before?"

"No, it isn't necessary. Everything is automatic. The bar is held parallel to the guiding compa.s.s, and signal bells ring whenever any of the instruments show a trace of abnormal behavior. Don't forget that there is at least one meter registering and recording every factor of our flight. With this control system we can't get into any such jam as we did last trip."

"Surely you are not suggesting that we run all night with no one at the controls?"

"Exactly that. A man camping at this board is painting the lily and gilding fine gold. Awake or asleep n.o.body need be closer to it than is necessary to hear a bell if one should ring, and you can hear them all over the ship. Furthermore, I'll bet a hat we won't hear a signal a week. Simply as added precaution, though, I've run lines so that any time one of these signals lets go, it sounds a buzzer on the head of our bed, so I'm automatically taking the night shift. Remember, Mart, these instruments are thousands of times as sensitive as the keenest human senses--they'll spot trouble long before we could, even if we were looking right at it."

"Of course, you understand these instruments much better than I do, as yet. If you trust them, I am perfectly willing to do the same.

Goodnight."

Seaton sat down and Dorothy nestled beside him, her head snuggled into the curve of his shoulder.

"Sleepy, cuddle-pup?"

"Heavens, no! I couldn't sleep now, lover--could you?"

"Not any. What's the use?"

His arm tightened around her. Apparently motionless to its pa.s.sengers, the cruiser bored serenely on into s.p.a.ce, with ever-mounting velocity.

There was not the faintest sound, not the slightest vibration--only the peculiar violet glow surrounding the shining copper cylinder in its ma.s.sive universal bearing gave any indication of the thousands of kilowatts being generated in the mighty intra-atomic power-plant. Seaton studied it thoughtfully.

"You know, if that violet aura and copper bar were a little different in shade and tone of color, they'd be just like your eyes and hair," he remarked finally.

"You burn me up, d.i.c.k!" she retorted, her entrancing low chuckle bubbling through her words. "You do say the weirdest things at times!

Possibly they would--and if the moon were made of different stuff than it is and had a different color, it might be green cheese, too! What say we go over and look at the stars?"

"As you were, Rufus!" he commanded sternly. "Don't move a millimeter--you're a drive fit, right where you are. I'll get you any stars you want, and bring them right in here to you. What constellation would you like? I'll get you the Southern Cross--we never see it in Washington."

"No, I want something familiar; the Pleiades or the Big Dipper--no, get me Canis Major--'where Sirius, brightest jewel in the diadem of the firmament, holds sway'," she quoted. "There! Thought I'd forgotten all the astronomy you ever taught me, didn't you? Think you can find it?"

"Sure. Declination about minus twenty, as I remember it, and right ascension between six and seven hours. Let's see--where would that be from our course?"

He thought for a moment, manipulated several levers and dials, snapped off the lights, and swung number one exterior visiplate around, directly before their eyes.

"Oh.... Oh ... this is magnificent, d.i.c.k!" she exclaimed. "It's stupendous. It seems as though we were right out there in s.p.a.ce itself, and not in here at all. It's ... it's just too perfectly darn wonderful!"

Although neither of them was unacquainted with interstellar s.p.a.ce, it presents a spectacle that never fails to awe even the most seasoned observer: and no human being had ever before viewed the wonders of s.p.a.ce from such a coign of vantage. Thus the two fell silent and awed as they gazed out into the abysmal depths of the interstellar void. The darkness of Earthly night is ameliorated by light-rays scattered by the atmosphere: the stars twinkle and scintillate and their light is diffused, because of the same medium. But here, what a contrast! They saw the utter, absolute darkness of the complete absence of all light: and upon that indescribable blackness they beheld superimposed the almost unbearable brilliance of enormous suns concentrated into mathematical points, dimensionless. Sirius blazed in blue-white splendor, dominating the lesser members of his constellation, a minute but intensely brilliant diamond upon a field of black velvet--his refulgence unmarred by any trace of scintillation or distortion.

As Seaton slowly shifted the field of vision, angling toward and across the celestial equator and the ecliptic, they beheld in turn mighty Rigel; The Belt, headed by dazzlingly brilliant-white Delta-Orionis; red Betelguese; storied Aldebaran, the friend of mariners; and the astronomically constant Pleiades.

Seaton's arm contracted, swinging Dorothy into his embrace; their lips met and held.

"Isn't it wonderful, lover," she murmured, "to be out here in s.p.a.ce this way, together, away from all our troubles and worries? I am so happy."

"It's all of that, sweetheart mine!"

"I almost died, every time they shot at you. Suppose your armor cracked or something? I wouldn't want to go on living--I'd just naturally die!"

"I'm glad it didn't--and I'm twice as glad that they didn't succeed in grabbing you away from me...." His jaw set rigidly, his gray eyes became hard as tempered drills. "Blackie DuQuesne has something coming to him.

So far, I have always paid my debts.... I shall settle with him ... IN FULL."

"That was an awfully quick change of subject," he continued, his voice changing instantly into a lighter vein, "but that's one penalty of being human. We can't live in high alt.i.tudes all our lives--if we could there would be no thrill in ascending them so often.

"Yes, we love each other just the same--more than anybody else I ever heard of." After a moment she eyed him shrewdly and continued:

"You've got something on your mind besides that tangled mop of hair, big boy. Tell it to Red-Top."

"Nothing much...."

"Come on, 'fess up--it's good for the soul. You can't fool your own wife, guy; I know your little winning ways too well."

"Let me finish, woman; I was about to bare my very soul. To resume--nothing much to go on but a hunch, but I think DuQuesne's somewhere out here in the great open s.p.a.ces, where men are sometimes schemers as well as men; and if so, I'm after him--foot, horse, and marines."

"That object compa.s.s?"

"Yes. You see, I built that thing myself, and I know darn well it isn't out of order. It's still on him, but doesn't indicate. Ergo, he is too far away to reach--and with his weight, I could find him anywhere up to about one and a half light-years. If he wants to go that far away from home, where is his logical destination? It can't be anywhere but Osnome, since that is the only place we stopped at for any length of time--the only place where he could have learned anything. He's learned something, or found something useful to him there, just as we did. That is certain, since he is not the type of man to do anything without a purpose. Uncle Dudley is on his trail--and will be able to locate him pretty soon."

"When will you get that new compa.s.s-case exhausted to a skillionth of a whillimeter or something, whatever it is? I thought Dunark said it took five hundred hours of pumping to get it where he wanted it?"

"It did him--but while the Osnomians are wonders at some things, they're not so hot at others. You see, I've got three pumps on that job, in series. First, a Rodebush-Michalek super-pump[A] then, backing that, an ordinary mercury-vapor pump, and last, backing both the others, a Cenco-Hyvac motor-driven oil pump. In less than fifty hours that case will be as empty as a flapper's skull. Just to make sure of cleaning up the last infinitesimal traces, though, I'm going to flash a getter charge of tantalum in it. After that, the atmosphere in that case will be tenuous--take my word for it."

"I'll have to; most of that contribution to science being over my head like a circus tent. What say we let _Skylark Two_ drift by herself for a while, and catch us some of Nature's sweet restorer?"
