“And that gun sounded exactly like the one that knocked the bridge to bits,” added Josh.

“Let’s hope, then, the fellows across on the hills there recognize its bark!” George exclaimed with considerable fervor, “and realize that it isn’t around this region any longer. Then they won’t bother wasting any more of their ammunition in bombarding this place.”

Apparently this was just what happened, for that shell was not followed by others, much to the relief of the boys. Buster in his heart even forgave the Austrians all they had done to nearly frighten him to death because of their forbearance now.

“No use wasting your good stuff any more, Mr. Austrian General,” he announced, “because the bully little Serbs have been too smart for you. They shot their bolt and then changed partners, just like you might do in dancing the Lancers. So call it off and settle down again.”

The firing still kept up, however.

“They’ve got oceans of ammunition up there,” remarked George, “and have been just aching to expend some of it, which is why they keep on whanging away when they haven’t any more chance to hit anything than you’d meet with in finding a needle in a haystack.”

“But they won’t try to keep it up all night long, I hope?” Buster observed.

“Not much danger of that,” Jack told him, knowing the other was fretting.

“I wonder if the boy and his kid sister will manage to get into Belgrade, and also find their mother alive?” Josh went on to say, showing that even in the midst of all that horrible confusion he could let his thoughts stray to the pair whom they had so generously assisted in their great trouble.

“We’ll hope so, anyway,” George added, for he, too, had been greatly drawn to the winsome little lassie with the bright eyes, now able to see as well as any one.
