So it was agreed.
The question of provisions was the next consideration. At Hakon’s orders, large quantities of evaporated fruits and vegetables had previously been placed within the cupboards of the Sphere. A goodly quantity of the Sphere’s original supply of food tablets, etc., remained. Fortunately, too, the oxygen tanks contained enough gas to purify the air in the Sphere for a long while. It only was necessary to replenish their water supply, when they could also leave Dyarkon.
The latter task was not so easy as it sounds. For there are no convenient, open streams on Mars. They must either chance landing at some power station or farm, or fly to one of the poles and there obtain water from one of the giant reservoirs. The elements at the nearest pole being very treacherous at this season, it was decided to chance a visit to some farmhouse.
A hurried trip was accordingly made to a small farm, a sufficient distance from the scene of the rebellion to be reasonably safe. Here the astonished farmer, who had not yet heard of the rebellion and who did not even recognize the emperor and the princess, eagerly helped these distinguished visitors to fill the water tanks of the mysterious Sphere. This the farmer had heard of, and both he and his wife gazed upon it with mingled wonder and dismay. Afterward they followed it with their eyes until it had passed beyond their vision. This farmer, and his wife and Dyarkon, had the distinction of being the persons on Mars who last saw their emperor; though the two first named did not know this till Dyarkon presently told them.
After the filling of the water tanks, Robert steered the Sphere straight toward the distant pale star which he and Professor Palmer knew was the Earth. Despite their anticipation and resignation, Zola and her father gazed back upon their erstwhile world in silent awe, and not without some sadness, long after it had ceased to be more than a mere ocher and rose disk.
Through the eternal night sped the infinitesimal world with its population of four. And through the long hours of Robert’s watches, Zola was at his side always. Their love was as an immortal thing, born of space and eternity. Hand in hand they fled across the universe to their future world of promise.
Profiting by their previous experience with gravitation, or rather, an absence of gravitation and stabilization, Robert and the professor properly manipulated the disk and gyrostats on this trip, avoiding the danger which had so nearly proved their undoing before. Robert prevented also the recurrence of another unpleasant experience, by cutting short pieces of stout cord, one for each of them, and particularly cautioned Zola and her father to tie them about their bodies at night and secure the other end to a rung or some other stationary object at a safe distance from the whirling gyrostats.
It was not long after that they had a taste of air-floating, and the cords proved their worth. This sensation, the continued sunshine out of a black sky and other phenomena, were all new to Zola and her father. The time passed rapidly.
A deck of playing cards was got out and Hakon and Zola were initiated into the mysteries of the Earthmen’s card games, which they learned readily and seemed to enjoy keenly. They then proceeded to show Robert and Professor Palmer some of their own games. These, being played with cards not greatly different from our own, were easily adapted to the cards they were using. In fact, one of their games, called Agahr, was virtually identical with our own simple game of casino.
So it did not seem long ere they were within a day’s journey of the Earth. Not a single mishap had delayed their progress so far. Barring the unexpected, they should be but a day longer in returning than the period covered by the trip to Mars, in spite of the considerably increased distance between the two planets by this time. Nearly three months had elapsed since the departure from the Earth.
