“But there are great differences in the conditions of life amongst the people of this race, some being fairly civilized while others are only beasts of burden, and still others take the place of dumb machines. They are specially adapted to act as wheels for light carriages. The axles of the carriage are terminated at each end with a six pronged fork, the prongs arranged in a circle or cylinder so that when a man is to play the role of wheel, he is impaled on this fork one prong of it fitting snugly between each pair of his legs. A vehicle of this kind is specially adapted for soft roads as the broad disc like feet prevent sinking. “The king has a phaeton mounted on twelve foot specimens of these lively wheels, in which he dashes around at a thirty or forty mile gait when the fancy strikes him. He also has a royal barge propelled by the same sort of wheels, the legs acting as paddles. “The king is imitated in his fads by the nobility and gentry as far as they are able, and so one may quite often see these live wheel phaetons, and live-paddle boats moving about. “On the public roads, vehicles are used having wheels such as you use, and drawn by these creatures, yoked together in pairs by the pronged shafts or axles like those I just described. From 5 to 10 pairs may sometimes be seen tugging at one of these heavy freight wagons. They are tremendously strong and their strength counts for vastly more on the planet Mars than it would on the earth, because Mars being so much smaller everything weighs very much less. I have seen some of those big fellows after rolling a few hundred yards with great speed give a leap from the ground and fly whirling through the air for two hundred feet before they lit.” “They are a wonderful race,” said I, “but it seems difficult to connect intelligence with a tribe of star fishes or to imagine they could ever become highly developed. You know those we have on earth are very low in the scale of existence.” “Intelligence,” said the Professor, “does not depend on the form. Any form on which it is possible for the forces of the environment such as light heat contact etc., to make an impression, already has intelligence; the ability to be impressed is intelligence. If any organism can be impressed, then if you give it time enough it can be impressed indefinitely, because each impression differentiates it and adds to its sensitiveness, that is, its ability to be further impressed. The reason why inferior races so generally remain inferior is the jealousy and hostility of the superior. The dominant race is always hostile to any other race that shows any intelligence, and proceeds to kill it off for fear it will become a rival. It is thus that the race of man has no rivals that compare with him in intelligence, no “connecting links” between him and the monkeys. He was jealous of them and exterminated them.
