It was impossible now to escape discovery.  Her only hope lay in flight.  If she could elude them and reach the hills and the flier ahead of them she might escape, and that could be accomplished in but one way—­flight, immediate and swift.  Leaping to her feet she darted along the base of the wall which she must skirt to the opposite side, beyond which lay the hill that was her goal.  Her act was greeted by strange whistling sounds from the things behind her, and casting a glance over her shoulder she saw them all in rapid pursuit.

There were also shrill commands that she halt, but to these she paid no attention.  Before she had half circled the enclosure she discovered that her chances for successful escape were great, since it was evident to her that her pursuers were not so fleet as she.  High indeed then were her hopes as she came in sight of the hill, but they were soon dashed by what lay before her, for there, in the fields that lay between, were fully a hundred creatures similar to those behind her and all were on the alert, evidently warned by the whistling of their fellows.  Instructions and commands were shouted to and fro, with the result that those before her spread roughly into a great half circle to intercept her, and when she turned to the right, hoping to elude the net, she saw others coming from fields beyond, and to the left the same was true.  But Tara of Helium would not admit defeat.  Without once pausing she turned directly toward the center of the advancing semi-circle, beyond which lay her single chance of escape, and as she ran she drew her long, slim dagger.  Like her valiant sire, if die she must, she would die fighting.  There were gaps in the thin line confronting her and toward the widest of one of these she directed her course.  The things on either side of the opening guessed her intent for they closed in to place themselves in her path.  This widened the openings on either side of them and as the girl appeared almost to rush into their arms she turned suddenly at right angles, ran swiftly in the new direction for a few yards, and then dashed quickly toward the hill again.  Now only a single warrior, with a wide gap on either side of him, barred her clear way to freedom, though all the others were speeding as rapidly as they could to intercept her.  If she could pass this one without too much delay she could escape, of that she was certain.  Her every hope hinged on this.  The creature before her realized it, too, for he moved cautiously, though swiftly, to intercept her, as a Rugby fullback might maneuver in the realization that he alone stood between the opposing team and a touchdown.
