By the end of the third day the court barber—I can think of no other earthly appellation by which to describe him—had wrought so remarkable a transformation in both Thuvan Dihn and myself that our own wives would never have known us. Our skins were of the same lemon color as his own, and great, black beards and mustaches had been deftly affixed to our smooth faces. The trappings of warriors of Okar aided in the deception; and for wear beyond the hothouse cities we each had suits of the black- and yellow-striped orluk.
Talu gave us careful directions for the journey to Kadabra, the capital city of the Okar nation, which is the racial name of the yellow men. This good friend even accompanied us part way, and then, promising to aid us in any way that he found possible, bade us adieu.
On parting he slipped upon my finger a curiously wrought ring set with a dead-black, lusterless stone, which appeared more like a bit of bituminous coal than the priceless Barsoomian gem which in reality it is.
“There had been but three others cut from the mother stone,” he said, “which is in my possession. These three are worn by nobles high in my confidence, all of whom have been sent on secret missions to the court of Salensus Oll.
“Should you come within fifty feet of any of these three you will feel a rapid, pricking sensation in the finger upon which you wear this ring. He who wears one of its mates will experience the same feeling; it is caused by an electrical action that takes place the moment two of these gems cut from the same mother stone come within the radius of each other’s power. By it you will know that a friend is at hand upon whom you may depend for assistance in time of need.
“Should another wearer of one of these gems call upon you for aid do not deny him, and should death threaten you swallow the ring rather than let it fall into the hands of enemies. Guard it with your life, John Carter, for some day it may mean more than life to you.”
With this parting admonition our good friend turned back toward Marentina, and we set our faces in the direction of the city of Kadabra and the court of Salensus Oll, Jeddak of Jeddaks.
That very evening we came within sight of the walled and glass-roofed city of Kadabra. It lies in a low depression near the pole, surrounded by rocky, snow-clad hills. From the pass through which we entered the valley we had a splendid view of this great city of the north. Its crystal domes sparkled in the brilliant sunlight gleaming above the frost-covered outer wall that circles the entire one hundred miles of its circumference.
At regular intervals great gates give entrance to the city; but even at the distance from which we looked upon the massive pile we could see that all were closed, and, in accordance with Talu’s suggestion, we deferred attempting to enter the city until the following morning.
As he had said, we found numerous caves in the hillsides about us, and into one of these we crept for the night. Our warm orluk skins kept us perfectly comfortable, and it was only after a most refreshing sleep that we awoke shortly after daylight on the following morning.
