“Look at the beautiful bridge we’re going to pass under,” sang out Buster presently. “It makes me think of one we saw in London.”

“There’s a bunch of Austrian officers walking across,” said Josh, “and see how one of them is pointing to us now.”

“Bet you they’re suspicious of us right away, and mean to order us to go back,” said George disconsolately.

“Rats!” scoffed Buster. “Don’t you see they’re only admiring our little flag?—that’s all. I’ve got the same fastened in the stern, where it can show well. I only wish it was five times as big, that’s all. But it stands for what we are—true-blooded Americans, every one of us.”

The officers even leaned over the parapet of the bridge to stare at the boat as it passed under. When the boys looked back a minute or so later they saw that the uniformed Hungarians had hurriedly crossed over and were now gazing after them.

“Shows how seldom Old Glory is ever seen in these parts,” said Josh, “for they hardly know what to make of it. If I had my way, can you guess what I’d do? Make the flag of the free so well known and respected that everywhere people’d kowtow to the same and take off their hats.”

“Now they’re hurrying off the bridge, seems like, as if they’d just remembered an engagement somewhere,” reported Buster.

“I only hope they don’t start any sort of trouble for us, that’s all,” George went on to say, but, finding that no one seemed to be paying any sort of attention to his grumbling, he stopped short, as his kind always do.

Jack held the wheel and guided the boat along through the numerous mazes of moving river craft. He was a skillful pilot and could be depended on to mind his business every time. Unlike George, Jack was plain and practical, whereas the other never seemed satisfied with what he had, but was always trying to better conditions, often to his own and others’ discomfort, as well as possible delay.

By degrees they were now leaving the twin cities behind them, and the river began to appear more open and free to travel. The boys, as usual, were calling each other’s attention to such features of the landscape that attracted their admiration, or it might be some of the buildings they passed.
