And Quivven, the golden-furred Vairking maiden, would be even more difficult to explain. She was beautiful, even by Cupian standards. She was more nearly the same race as Myles than was his own wife, Lilla. She and Myles could talk together, unheard by the radio-sense of Lilla. In these circumstances, it was hardly possible that the Princess Lilla would receive Quivven with open arms, or even be passably decent to her. At this point, his reveries was interrupted by Doggo handing him the following note: If we are to await passers-by, do you not think it would be well to return to the plane and secure our rifles, so as to protect ourselves in case the passers-by should prove to be hostile? Myles nodded his assent, and informed Quivven of their intentions. She, being nearer to the point where they had entered the road, plunged through the bushes at once, and they hastened after her. Just as Myles and Doggo were breaking through the bushes in the wake of the golden one, they heard an agonized scream ahead. Redoubling their efforts, they reached the clearing in an instant, and beheld a most unexpected sight! Perched upon the airship, like a flock of enormous vultures, were about a dozen huge, bat-winged, pale green reptiles, each with a wing-spread of fully ten-feet; and one of these loathsome creatures held the writhing form of Quivven tight in its claws. Without a moment’s thought for his own safety, the intrepid earth-man drew the Vairkingian sword which hung at his side, and rushed straight at the beast which held the girl. Doggo followed close behind, clicking his mandibles angrily. But before they could reach the plane, the noisome flock flapped heavily into the air and disappeared over the trees to the northward, Quivven’s childish face an agony of despair, and one little furry paw waving a forlorn farewell. The next move was obvious. Myles and Doggo sprang to their places in the aircraft and soared after. It was an easy matter to overtake the clumsy-winged saurians, but not so easy to decide what to do after reaching them. The reptiles flew so close together their pursuers were afraid to fire on them for fear of hitting Quivven. The girl was as yet apparently unharmed, so the only thing to do seemed to be to follow and watch for some opportunity to effect a rescue. Thus the chase continued for several stads without event. Myles was in an agony for the safety of his little friend, but even his deep concern did not keep his scientific mind from speculating about the pale green dragons which he was following. He had read about such beasts in books on paleontology as a child. These were undoubtedly pterodactyls. He had seen somewhat similar stuffed specimens in the imperial museum at Kuana, capital of Cupia. He had encountered swarms of tiny pterosaurs, the size of sparrows, in the caves of Kar. But he had been informed by Cupian scientists that the larger species had long since become extinct on Poros.
