resolve into execution, but at the moment of the shriek each member of the herd turned in the direction from which the sound seemed to come, and at the same instant every particular snake-like hair upon their heads rose stiffly perpendicular as if each had been a sentient organism looking or listening for the source or meaning of the wail. And indeed the latter proved to be the truth, for this strange growth upon the craniums of the plant men of Barsoom represents the thousand ears of these hideous creatures, the last remnant of the strange race which sprung from the original Tree of Life.
Instantly every eye turned toward one member of the herd, a large fellow who evidently was the leader. A strange purring sound issued from the mouth in the palm of one of his hands, and at the same time he started rapidly toward the bluff, followed by the entire herd.
Their speed and method of locomotion were both remarkable, springing as they did in great leaps of twenty or thirty feet, much after the manner of a kangaroo.
They were rapidly disappearing when it occurred to me to follow them, and so, hurling caution to the winds, I sprang across the meadow in their wake with leaps and bounds even more prodigious than their own, for the muscles of an athletic Earth man produce remarkable results when pitted against the lesser gravity and air pressure of Mars.
