With the coming of the Sun the great Barsoomian lion rose to his feet.  He turned angry eyes upon the girl above him, voiced a single ominous growl, and slunk away toward the hills.  The girl watched him, and she saw that he gave the towers as wide a berth as possible and that he never took his eyes from one of them while he was passing it.  Evidently the inmates had taught these savage creatures to respect them.  Presently he passed from sight in a narrow defile, nor in any direction that she could see was there another.  Momentarily at least the landscape was deserted.  The girl wondered if she dared to attempt to regain the hills and her flier.  She dreaded the coming of the workmen to the fields as she was sure they would come.  She shrank from again seeing the headless bodies, and found herself wondering if these things would come out into the fields and work.  She looked toward the nearest tower.  There was no sign of life there.  The valley lay quiet now and deserted.  She lowered herself stiffly to the ground.  Her muscles were cramped and every move brought a twinge of pain.  Pausing a moment to drink again at the stream she felt refreshed and then turned without more delay toward the hills.  To cover the distance as quickly as possible seemed the only plan to pursue.  The trees no longer offered concealment and so she did not go out of her way to be near them.  The hills seemed very far away.  She had not thought, the night before, that she had traveled so far.  Really it had not been far, but now, with the three towers to pass in broad daylight, the distance seemed great indeed.

The second tower lay almost directly in her path.  To make a detour would not lessen the chance of detection, it would only lengthen the period of her danger, and so she laid her course straight for the hill where her flier was, regardless of the tower.  As she passed the first enclosure she thought that she heard the sound of movement within, but the gate did not open and she breathed more easily when it lay behind her.  She came then to the second enclosure, the outer wall of which she must circle, as it lay across her route.  As she passed close along it she distinctly heard not only movement within, but voices.  In the world-language of Barsoom she heard a man issuing instructions—­so many were to pick usa, so many were to irrigate this field, so many to cultivate that, and so on, as a foreman lay out the day’s work for his crew.

Tara of Helium had just reached the gate in the outer wall.  Without warning it swung open toward her.  She saw that for a moment it would hide her from those within and in that moment she turned and ran, keeping close to the wall, until, passing out of sight beyond the curve of the structure, she came to the opposite side of the enclosure.  Here, panting from her exertion and from the excitement of her narrow escape, she threw herself among some tall weeds that grew close to the foot of the wall.  There she lay
