wrought in your appearance before you can hope to enter any city in Okar. You must have yellow faces and black beards, and your apparel and trappings must be those least likely to arouse suspicion. In my palace is one who can make you appear as truly yellow men as does Salensus Oll himself."

His counsel seemed wise; and as there was apparently no other way to insure a successful entry to Kadabra, the capital city of Okar, we set out with Talu, Prince of Marentina, for his little, rock-bound country.

The way was over some of the worst traveling I have ever seen, and I do not wonder that in this land where there are neither thoats nor fliers that Marentina is in little fear of invasion; but at last we reached our destination, the first view of which I had from a slight elevation a half-mile from the city.

Nestled in a deep valley lay a city of Martian concrete, whose every street and plaza and open space was roofed with glass. All about lay snow and ice, but there was none upon the rounded, domelike, crystal covering that enveloped the whole city.

Then I saw how these people combatted the rigors of the arctic, and lived in luxury and comfort in the midst of a land of perpetual ice. Their cities were veritable hothouses, and when I had come within this one my respect and admiration for the scientific and engineering skill of this buried nation was unbounded.

The moment we entered the city Talu threw off his outer garments of fur, as did we, and I saw that his apparel differed but little from that of the red races of Barsoom. Except for his leathern harness, covered thick with jewels and metal, he was naked, nor could one have comfortably worn apparel in that warm and humid atmosphere.

For three days we remained the guests of Prince Talu, and during that time he showered upon us every attention and courtesy within his power. He showed us all that was of interest in his great city.

The Marentina atmosphere plant will maintain life indefinitely in the cities of the north pole after all life upon the balance of dying Mars is extinct through the failure of the air supply, should the great central plant again cease functioning as it did upon that memorable occasion that gave me the opportunity of restoring life and happiness to the strange world that I had already learned to love so well.

He showed us the heating system that stores the sun's rays in great reservoirs beneath the city, and how little is necessary to maintain the perpetual summer heat of the glorious garden spot within this arctic paradise.

Broad avenues of sod sewn with the seed of the ocher vegetation of the dead sea bottoms carried the noiseless traffic of light and airy ground fliers that are the only form of artificial transportation used north of the gigantic ice-barrier.

The broad tires of these unique fliers are but rubber-like gas bags filled with the eighth Barsoomian ray, or
