elson's heart stopped as a small, dark object sailed up from below and clattered on the platform. It was a grenade. With the speed of thought, the American kicked it to the landing below, where it exploded, annihilating a detachment of Jarmuthians by drenching them with the terrible fungus gas. Heart bounding with savage joy, Nelson watched the deadly green fog leap from the broken grenade and of its own accord settle on the nearest soldiers. With the usual astonishing speed there formed on the stricken soldiery that poisonous yellow mould, whose fungus-like shoots sprouted through nostrils and mouths. On the dense crowd below the bomb's effect was appalling, and no more grenades were hurled....

During the respite Nelson's anguished eyes once more swept the skies. He started. Was it true or was it a mirage? Far to the southward a small, black speck materialized in the orange-hued heavens. Good old Alden! Hope wavered in the American's breast. Could he and his two fellows beat off the infuriated Jarmuthians long enough? He doubted it.

A shower of spears sailed up, but because of the angle, their trajectory was too great, and like rays of death the lances flashed harmlessly overhead to plunge over the summit and wreak death among those on the other side.

Nearer and nearer came the black speck while from the populace a low shout of amazement arose. Coincidently Nelson's heart stopped; aghast, he saw that the steam was no longer hissing from the holes at the idol's feet! Evidently, the steam current had been shut off from below to allow the raging priests to lead their followers in a desperate charge up the stairs.

Marshalling an Atlantean to either side, Nelson sprang to the head of the stair and fired full in the face of gorgeously robed priests who staggered back screaming. But the others wavered only an instant.

"Halor vàn!" Both Atlanteans hurled spears retrieved from the abandoned weapons—and each struck down his man.


he American's eye flickered up. Yes, there came a strange, but welcome sight: a great creature with enormous, leathery pinions was circling down towards the tower top! A clashing of weapons brought Nelson's eyes earthwards. He joined in a furious melée at the stair top, like the Atlanteans, using a captured bronze sword. There came a deep groan as the right-hand Atlantean collapsed with a bloodied bronze spear point standing far out from between his naked shoulder blades.
