A WIRELESS MESSAGE TO HEADQUARTERS

The goblin silently handed the small black satchel to his comrade. The boy opened it and took out two of the tiny bottles, remarking as he did so:

“I—I rather hate to do it; but I’ve got to—we’ve got to save ourselves.”

“But what do you mean to do, Bob?” his companion insisted. “Tell me—before the Arabs get here.”

The boy silently shook a few tablets into his palm from each of the two bottles. Then he queried:

“Fitz, does the—the effect of these tablets—these gob-tabs—last forever? Tell me the truth.”

“The effect lasts as long as the person eats goblin diet, Bob. That’s the reason I’ve insisted on your eating nothing else. See?”

“Uh-huh.”

“Well, now what’re you going to do?”

“Going to give those Arabs some gob-tabs.”

“How are you going to get them to take the gobs?” asked the little green sprite, grinning broadly.

[132]

“You just watch me and see,” Bob replied complacently; “and do whatever I tell you to do.”

“All right. But you’ve got some giant-tabs there, too. What are you going to do with those?”

“You’ll see. Hist! Here come the Arabs. Now, don’t you hesitate to do what I tell you, Fitz.”

“I won’t, Bob.”

The Arabs, some on horses and others on camels, came galloping to the spot, raising a great cloud of sand. They formed in a circle round the two diminutive aëronauts and their balloon; and dismounted and stood silently, sullenly scowling.

At last the sheik of the tribe advanced and said:

“You two are devils. You’ve poisoned the spring where we drink and refresh[133] ourselves and our beasts. You must die; we’re going to kill you.”

Bob replied composedly: “Great sheik, we are magicians, not devils. We worked enchantment upon the spring, but did not poison it. As soon as the sun shines a few hours, the waters of the spring will again be pure and sweet—purer and sweeter than ever before. To convince you that we’re magicians, we’re ready to perform before you. See! I will make a giant of my green comrade.”

The boy gave a giant-tab to the goblin and motioned him to swallow it. Unhesitatingly Fitz obeyed; and almost immediately he grew and swelled to gigantic size. With gestures and cries of amazement the Arabs drew back. Several of them touched their foreheads and muttered strange words; others prostrated themselves and hid their faces upon their extended arms. But the fierce old sheik gave no sign of wonder or fear. Instead, he said firmly, boldly:

“Devils can work magic upon devils; but devils cannot work magic upon Allah’s elect. I’ll put you to the test; and if you fail,—as you will!—you die. Give me and my children of your magic medicine.”

At a word from their sheik, the Arabs formed a line. Then the fierce old warrior of the desert said:

“My children, these devils cannot injure you with their magic medicine. If they succeed in making giants of us, we shall then be able to overcome all our enemies; if they fail, we shall be as we are—and[134] the devils shall die.” Then to Bob: “Give us of your devil drugs.”

The boy stepped forward and dropped a gob-tab into the outstretched palm of each warrior. The sheik gave a signal; and twenty red mouths flew open and twenty gob-tabs disappeared. At the same moment Bob took a giant-tab. And a few minutes later two giants stood triumphantly grinning down upon twenty bearded and turbaned pygmies!

“Now, sheik,” Bob roared briskly and cheerily, “no doubt you’re convinced that we’re what we claim to be—great magicians. But we don’t mean to work you any injury, now that we’re big and you’re small; although you meant to put us to death, just because you were big and we were small. You’ll come back to your natural size all right, in a few days. And we’re not going to rob you; just going to borrow two of your camels.”

The sheik had stood silently staring at his diminutive warriors and inspecting his own shrunken limbs. But now he piped shrilly:

“Allah is great! Allah is great! But what use can you have for our camels? You are so huge that they cannot bear you!”

“Say!” Bob muttered in consternation. “Fitz, that’s a fact. What are we to do? I meant to take two of the camels to carry us and our balloon out of reach of the power of the magnetic mountain. What are we to do?”

Two giants stood triumphantly grinning down upon twenty pygmies.

[135]

“I don’t know,” the goblin-giant grumbled surlily.

“Well, can’t you think of some plan?”

“You’re the one, Roberty-Boberty, that’s making the plans this time.” And Fitz Mee grinned a grin that made his big fat face look simply awful.

“I know,” Bob admitted ruefully. “But won’t you help a fellow out, when he’s doing the best he can?”

“Say, Bob!”

“What?”—eagerly, expectantly.

“I’ll tell you what! We’ll have to take gob-tabs and go back to goblin size. Then the camels can carry us.”

“Yes, but we couldn’t manage the camels—couldn’t get on ’em, even,” the boy-giant objected. “Could we?”

“I’m afraid we couldn’t,” the goblin-giant admitted, shaking his head. “I hadn’t thought of that.”

“Oh, dear!” groaned Bob.

“Oh, dear!” seconded Fitz.

“Say!” squeaked the old sheik, looking up at the two giants. “What are we Arabs to do? We are so small we cannot mount and manage our beasts.”

“I don’t know,” rumbled Bob.

“And I don’t know,” mumbled Fitz.

“Well, you’re a nice pair of magicians—you are!” screeched the[136] sheik, pulling at his long beard. “Don’t you know anything you can do to help us out of our quandary?”

Each giant sadly shook his big head.

“Well,” the old sheik screeched, “I know what you’ve got to do—you’ve got to give our beasts some of your magic medicine, and shrink ’em.”

“Oh!” Bob ejaculated.

“Oh!” Fitz exclaimed.

“That’s a good idea,” the boy-giant remarked.

“A splendid idea,” the goblin-giant agre............
