ll at once the fugitives, now reduced by exhaustion to five, found themselves on a balcony overlooking the great valley of Atlans. Before them opened an enormous staircase and down this they dashed at top speed, infinitely relieved to be once more in the open air.
Running like hunted stags, the fugitives had descended but a third of the great staircase, when, from behind, came a sudden, menacing cry that warned Nelson that the pursuers had, after going a longer way around, come once more in sight.
"Ah! Poseidon blast the traitorous Edmund and his varlets! See?" panted Hero Giles pointing to a huge arch from beneath which was issuing a glittering column of shouting, swift running warriors at whose head dashed a splendidly-proportioned figure that must be Hero Edmund.
With the speed of the hunted, Hero Giles bounded forward, taking three and four steps at a stride, his jade green cloak snapping out behind. Down, ever downwards over the endless flight of stairs the aviators followed him until, spent and panting, the hard pressed five plunged down a final circular staircase and so gained a courtyard where waited a detachment of armored lancers whose yellow plumes and pennons shone bright in the glare of the flame suns. Staring anxiously upwards, the troopers nevertheless stood to attention in an orderly rank beside those curious Atlantean mounts called podokos.
During all his sojourn in Atlans, Nelson had never become used to the hideous and awe-inspiring podokos which closely resembled the allosauri but were only eighteen feet long. Like the other monsters, they had tremendously developed hind legs which promised the speed now so vital for escape and safety. Ready in the tooth-studded jaws of each podoko was fitted a bronze bit together with a bridle and reins; and cinched up on each creature's back was one of those curious Atlantean saddles, which was built up at the cantle to overcome the downward slope of the podokos' spines.
Need for vital haste was but too obvious and, as he drew near, Hero Giles gasped the command to be off.
"Quick," he shouted, his scarred visage flushed and sweat-bathed. "Saddles! Speed! Speed! Cling fast as your beasts arise!"
