The frantic terror of those eyes appealed to that in her which was greater than her own personal fear.
She paused therefore, and in the pause there came to her ears a swelling tumult that arose from the ridge of an eminence a couple of fields away.
Right well Avery knew that sound.

In the far-off days of her early girlhood it had quickened her pulses many a time.

It was enough even now to set every nerve throbbing with a tense excitement.
She turned her face once more to the open, and as she did so she heard again in the hut behind her that agonized sound, half-cough, half-whine, of an animal exhausted and in the extremity of mortal fear.
It was enough for Avery.

She grasped the situation on the instant, and on the instant she acted.

She felt as if a helpless and tortured being had cried to her for deliverance, and all that was great in her responded to the cry.
She seized the crazy shutter that was propped against the wall, put forth her strength, and lifted it out into the open.
