The architecture was immaterial, however, compared with the fact that this was a city of some sort, a city of a high degree of civilization. The beasts were apparently headed straight for it, and thus there was every prospect of the inhabitants—presumably Cupians—rescuing Quivven.

Suppose, however, it was a deserted city. Its unfamiliar style and remote location suggested as much. Perhaps this was the long forgotten court of some Cupian Jamshyd, now kept by lion and lizard, or rather by woofus and pterodactyl.

This was not so, however; for, as Cabot drew nearer, he could clearly see that the buildings were in an excellent state of repair, with not a crumbling ruin among them. No, this was an inhabited city, to which the green dragons were bringing their prey. Could it be that the Cupian inhabitants kept these creatures as pets, and that this fact was unknown to the scientists at the Cupian metropolis?

Cabot’s cogitations were again cut short by his arrival over the city. The dragons made straight for an imposing centrally-located domed edifice, which they entered by one of the upper windows. The plane promptly dropped into a near-by plaza. Making a sign to the ant-man to guard the ship, Myles seized a rifle and cartridges, and rushed down a street which led toward the building which the green beasts had entered.

On the way he met several pterosaurs, four or five four-legged slate-colored reptiles ranging in size from that of a small dog to that of a horse, one large snake about thirty feet in length, various sorts of insects, and a few cat-like furry creatures; but not a single Cupian. If these were the pets of the city, where were their masters?

The strange creatures did not offer to molest him. In fact, they gave way to him with every indication of respect and not a little fear. This seemed to indicate that they were all thoroughly domesticated, so he made no effort to hurt them.

At last he arrived at the building which he sought. A wide incline led from the street up to its arched doorway. This smacked of Formia, for the ant-men before they were driven off the continent had used ramps everywhere instead of the flight of stairs employed by the Cupians.

Over the door was an inscription in unmistakable Porovian characters: “The Palace of the City of Yat.”

This must be Cupia, or old Formia—now occupied by the Cupians—for this was the language of those two races. But then, he reflected, it had also been the written language of the Vairkings, far across the boiling seas.

Putting an end to his speculations, he rushed up the ramp and entered the building.
