But Roberts shook his head.

"We sent a message, Jonesy, but I don't think it got through. I've just been looking at my portable. It seems to be busted. Happened when they first attacked us, I guess. I tripped and fell on it."

Isobar's last hope flickered out.

"Then I—I guess it won't be long now," he mourned. "If we could have only got a message through, they would have sent out an armored car to pick us up. But as it is—"

Brown's shrug displayed a bravado he did not feel.

"Well, that's the way it goes. We knew what we were risking when we volunteered to come Outside. This damn moon! It'll never be worth a plugged credit until men find some way to fight those murderous stones-on-legs!"

Roberts said, "That's right. But what are you doing out here, Isobar? And why, for Pete's sake, the bagpipes?"

"Oh—the pipes?" Isobar flushed painfully. He had almost forgotten his original reason for adventuring Outside, had quite forgotten his instrument, and was now rather amazed to discover that somehow throughout all the excitement he had held onto it. "Why, I just happened to—Oh! the pipes!"

"Hold on!" roared Roberts. His warning came just in time. Once more, the three tree-sitters shook like dried peas in a pod as their leafy refuge trembled before the locomotive onslaught of the lunar beasts. This time the already-exposed roots strained and lifted, several snapped; when the Grannies again withdrew, complacently unaware that the "lethal ray" of Brown's Haemholtz was wasting itself upon their adamant hides in futile fury, the tree was bent at a precarious angle.

Brown sobbed, not with fear but with impotent anger, and in a gesture of enraged desperation, hurled his now-empty weapon at the retreating Grannies.
