Immediately their plane was surrounded by a host of strange people. In form they were very much like the people of the earth. They were, however, much smaller and had heads large out of all proportion to their bodies. Clothes too, were not to be seen. Before they left the plane Carl warned Sana to be very careful how she moved about. As Mars is only one tenth the size of the earth in volume, gravitation is likewise less. Carl who, on earth weighed about one hundred and sixty pounds, would weigh but sixty-four or five pounds on Mars. He told Sana, jokingly, that she could easily step over their huge airplane, while a Martian would break his neck if he tried to jump over an ordinary soap box. To the Martians, Sana and Carl must have appeared quite strange, both as to size and clothing. For a time the crowd stood at a distance as if in awe of these strange beings that had come to them out of the skies. At length, however, one of the group stepped forward and spoke. Much to his surprise Carl realized that he understood him perfectly. And stranger, still, Carl found himself answering in a language that was new to his ears. Courteously they questioned him as to his desires, and being informed that Carl and Sana had flown through space from the earth, their amazement was without bounds. Would more follow him, they asked, to which Carl was quick to reply that none would come. Realizing their doubt, he assured them that he alone knew the secret of his flight and that no other earth-men could make the journey. Assured at last, that these two visitors had come without intent to harm, they led Carl and Sana to a great hall, where food and drink were served them. Food and drink such as they had never tasted before! The various dishes of chemical food had the same brown granular appearance, but when placed in the mouth each gave a different taste and had different satisfying qualities. The same applied to the drinks. One could not be distinguished from the other, either in appearance or odor, yet each was distinctly different to the palate. The hall or room and its furnishings, they noted, were very much like those of the earth. While this was indeed strange, Carl reasoned that there was no good reason why two worlds of people, although separated by untold miles, should not conceive things along the same lines. Having eaten, Carl and Sana were informed that they could come and go as they pleased among the people of Mars. Whatever they wished was theirs for the asking--as was the case with all Martians. This promise of freedom proved well founded. Together Carl and Sana studied and explored without interference, although they soon realized that their every move was witnessed by some Martian or other.
