"No good! Not a damn bit of good! Oh, if there was only some way of fighting those filthy things—"

But Isobar Jones had a one-track mind. "The pipes!" he cried again, excitedly. "That's the answer!" And he drew the instrument into playing position, bag cuddled beneath one arm-pit, drones stiffly erect over his shoulder, blow-pipe at his lips. His cheeks puffed, his breath expelled. The giant lung swelled, the chaunter emitted its distinctive, fearsome, "Kaa-aa-o-o-o-oro-oong!"

Roberts moaned.

"Stop talking!" roared Roberts. "Stop talking, guy, and start blowing! I think you've got something there. Anyhow, it's our last hope. Blow!"
