All these thoughts rushed through Muriel's mind as she tried to hurry the girls towards the railings, assisted by such of the mistresses and prefects as were near at hand. There had been many reports in the papers lately of dogs that had gone mad and bitten people, and the head girl was well aware of the terrible results that might follow a bite from an animal suffering from rabies. She knew that a mad dog bites and snaps at everything that comes in his way—and how could they hope to get all these children out of the way in time!

Very much the same thoughts had come into the mind of somebody else, too! Gerry had been seized with panic when the cry of "Mad dog!" had reached her ears, and her first instinct had been to dash towards the railings out of Bruno's way. It was not until she was nearly half-way to safety that it had dawned upon her that none of her three companions were with her, and she stopped for a moment to look round and see what they were doing.

She saw Alice and Monica hurrying some of the smaller children into safety, she saw Muriel running to warn the girls behind. Then she looked at Bruno, who was near enough for her to see him plainly now. His mouth was wide open, his tongue was hanging out, and foam was dripping from his jaws. He looked very terrible, not in the least like the good-natured dog with whom Gerry had made friends on her first day at school.

For a moment, Gerry turned away, with a sick shiver of fear and repulsion. Then all at once something came into her heart, making her braver and stronger than she had ever been in her life before. Muriel was being brave. Muriel had not run like a coward towards the fence. Why, couldn't she be brave like Muriel, too? With a sudden desperate resolve, Gerry swung round and flew straight towards the oncoming dog.

Nearly every girl and mistress in the school saw the deed by which Gerry Wilmott established herself for ever in the annals of Wakehurst Priory. The few who were absent could find plenty of eager eye-witnesses to describe it to them. It was a picture which stamped itself indelibly upon the minds of a good many of the people present—the old grey school buildings in the background, framed by the black boughs of the November trees, the wide stretch of meadowland, and in the forefront the big black dog, pursued by the shouting men, making straight for the crowd of terrified children.

Then into the very centre of the picture dashed the blue-tunicked figure of Gerry Wilmott! German Gerry! The girl who was afraid of dogs and mice and hockey balls, and everything and everyone under the sun, apparently—dashing right in the pathway of the mad dog!

Exactly how she did it, Gerry never afterwards quite knew. In some way she managed to get behind the dog and fling herself upon him as he rushed past. She seized him by his collar and the long curly hair about his throat, throwing herself upon her knees on the ground as she did so. So powerful was he in his mad frenzy, that she was dragged along the grass for a considerable distance before she could bring him to a standstill. Then came a few moments that seemed like a lifetime of desperate struggling, while she gripped the snapping, growling dog round his throat with fingers that grew numb beneath the strain, and with stiff, taut arms held him away so that he could not spring upon her.

The struggle only lasted a few moments in reality, but to Gerry it seemed an eternity before she heard Bennett's breathless cry of "Hold on, missie I keep him still an instant longer," and knew that if it was more than an instant, she would have to let the dog go. Then came a sudden blinding flash over her shoulder, a deafening report in her ear. Bruno broke from her grasp with a frenzied leap, then came another report. And then——

And then the next thing she knew was that she was lying on the grass with Muriel and Miss Caton and Miss Latham bending over her, and with what appeared to Gerry to be the whole of Wakehurst Priory peering over their shoulders.

"For Heaven's sake, keep back, you kids!" cried Muriel in an irate voice, thrusting back the nearest of the eager throng. "Can't you see that Gerry's nearly fainting, and you will keep crowding round so that she can't get a breath of air."
