The Marching Hordes

The bulletin board outside lecture hall 1712-A of Patrick Henry High School showed a flashing red light. Rod Walker pushed his way into a knot of students and tried to see what the special notice had to say. He received an elbow in the stomach, accompanied by: “Hey! Quit shoving!”

“Sorry. Take it easy, Jimmy.” Rod locked the elbow in a bone breaker but put no pressure on, craned his neck to look over Jimmy Throxton’s head. “What’s on the board?”

“No class today.”

“Why not?”

A voice near the board answered him. “Because tomorrow it’s ‘Hail, Caesar, we who are about to die—’ ”

“So?” Rod felt his stomach tighten as it always did before an examination. Someone moved aside and he managed to read the notice:


Department of Social Studies

j. r. roerich, for the Board

Rod Walker reread the notice slowly, while trying to quiet the quiver in his nerves. He checked off the test conditions—why, those were not “conditions” but a total lack of conditions, no limits of any sort! They could dump you through the gate and the next instant you might be facing a polar bear at forty below—or wrestling an octopus deep in warm salt water.

Or, he added, faced up to some three-headed horror on a planet you had never heard of.

He heard a soprano voice complaining, “ ‘Twenty-four hour notice!’ Why, it’s less than twenty hours now. That’s not fair.”

Another girl answered, “What’s the difference? I wish we were starting this minute. I won’t get a wink of sleep tonight.”

“If we are supposed to have twenty-four hours to get ready, then we ought to have them. Fair is fair.”

Another student, a tall, husky Zulu girl, chuckled softly. “Go on in. Tell the Deacon that.”

Rod backed out of the press, taking Jimmy Throxton with him. He felt that he knew what “Deacon” Matson would say . . . something about the irrelevancy of fairness to survival. He chewed over the bait in paragraph five; nobody would say boo if he dropped the course. After all, “Advanced Survival” was properly a college course; he would graduate without it.

But he knew down deep that if he lost his nerve now, he would never take the course later.

Jimmy said nervously, “What d’you think of it, Rod?”

“All right, I guess. But I’d like to know whether or not to wear my long-handled underwear. Do you suppose the Deacon would give us a hint?”

“Him? Not him! He thinks a broken leg is the height of humor. That man would eat his own grandmother—without salt.”

“Oh, come now! He’d use salt. Say, Jim? You saw what it said about teaming.”

“Yeah . . . what about it?” Jimmy’s eyes shifted away.

Rod felt a moment’s irritation. He was making a suggestion as delicate as a proposal of marriage, an offer to put his own life in the same basket with Jimmy’s. The greatest risk in a solo test was that a fellow just had to sleep sometime . . . but a team could split it up and stand watch over each other.

Jimmy must know that Rod was better than he was, with any weapon or bare hands; the proposition was to his advantage. Yet here he was hesitating as if he thought Rod might handicap him. “What’s the matter, Jim?” Rod said bleakly. “Figure you’re safer going it alone?”

“Uh, no, not exactly.”

“You mean you’d rather not team with me?”

“No, no, I didn’t mean that!”

“Then what did you mean?”

“I meant—Look, Rod, I surely do thank you. I won’t forget it. But that notice said something else, too.”


“It said we could dump this durned course and still graduate. And I just happened to remember that I don’t need it for the retail clothing business.”

“Huh? I thought you had ambitions to become a wide-angled lawyer?”

“So exotic jurisprudence loses its brightest jewel . . . so what do I care? It will make my old man very happy to learn that I’ve decided to stick with the family business.”

“You mean you’re scared.”

“Well, that’s one way of putting it. Aren’t you?”

Rod took a deep breath. “Yes. I’m scared.”

“Good! Now let’s both give a classic demonstration of how to survive and stay alive by marching down to the Registrar’s office and bravely signing our names to withdrawal slips.”

“Uh, no. You go ahead.”

“You mean you’re sticking?”

“I guess so.”

“Look, Rod, have you looked over the statistics on last year’s classes?”

“No. And I don’t want to. So long.” Rod turned sharply and headed for the classroom door, leaving Jimmy to stare after him with a troubled look.

The lecture room was occupied by a dozen or so of the seminar’s students. Doctor Matson, the “Deacon,” was squatting tailor-fashion on one corner of his desk and holding forth informally. He was a small man and spare, with a leathery face, a patch over one eye, and most of three fingers missing from his left hand. On his chest were miniature ribbons, marking service in three famous first expeditions; one carried a tiny diamond cluster that showed him to be the last living member of that group.

Rod slipped into the second row. The Deacon’s eye flicked at him as he went on talking. “I don’t understand the complaints,” he said jovially. “The test conditions say ‘all weapons’ so you can protect yourself any way you like . . . from a slingshot to a cobalt bomb. I think final examination should be bare hands, not so much as a nail file. But the Board of Education doesn’t agree, so we do it this sissy way instead.” He shrugged and grinned.

“Uh, Doctor, I take it then that the Board knows that we are going to run into dangerous animals?”

“Eh? You surely will! The most dangerous animal known.”

“Doctor, if you mean that literally—”

“Oh, I do, I do!”

“Then I take it that we are either being sent to Mithra and will have to watch out for snow apes, or we are going to stay on Terra and be dumped where we can expect leopards. Am I right?”

The Deacon shook his head despairingly. “My boy, you had better cancel and take this course over. Those dumb brutes aren’t dangerous.”

“But Jasper says, in Predators and Prey, that the two trickiest, most dangerous—”

“Jasper’s maiden aunt! I’m talking about the real King of the Beasts, the only animal that is always dangerous, even when not hungry. The two-legged brute. Take a look around you!”

The instructor leaned forward. “I’ve said this nineteen dozen times but you still don’t believe it. Man is the one animal that can’t be tamed. He goes along for years as peaceful as a cow, when it suits him. Then when it suits him not to be, he makes a leopard look like a tabby cat. Which goes double for the female of the species. Take another look around you. All friends. We’ve been on group-survival field tests together; we can depend on each other. So? Read about the Donner Party, or the First Venus Expedition. Anyhow, the test area will have several other classes in it, all strangers to you.” Doctor Matson fixed his eye on Rod. “I hate to see some of you take this test, I really do. Some of you are city dwellers by nature; I’m afraid I have not managed to get it through your heads that there are no policemen where you are going. Nor will I be around to give you a hand if you make some silly mistake.”

His eye moved on; Rod wondered if the Deacon meant him. Sometimes he felt that the Deacon took delight in rawhiding him. But Rod knew that it was serious; the course was required for all the Outlands professions for the good reason that the Outlands were places where you were smart—or you were dead. Rod had chosen to take this course before entering college because he hoped that it would help him to get a scholarship—but that did not mean that he thought it was just a formality.

He looked around, wondering who would be willing to team with him now that Jimmy had dropped out. There was a couple in front of him, Bob Baxter and Carmen Garcia. He checked them off, as they undoubtedly would team together; they planned to become medical missionaries and intended to marry as soon as they could.

How about Johann Braun? He would make a real partner, all right—strong, fast on his feet, and smart. But Rod did not trust him, nor did he think that Braun would want him. He began to see that he might have made a mistake in not cultivating other friends in the class besides Jimmy.

That big Zulu girl, Caroline something-unpronounceable. Strong as an ox and absolutely fearless. But it would not do to team with a girl; girls were likely to mistake a cold business deal for a romantic gambit. His eyes moved on until at last he was forced to conclude that there was no one there to whom he wished to suggest partnership.
