“About how far do you think we’ve come since leaving Budapest, Jack?” Buster asked, not deigning to continue the discussion with George.

“I should think something like fifty to sixty miles,” was the reply.

“Whew! as much as that?” whiffed George.

“Well, this current must be all of four miles an hour, and the old boat when going with it ought to average ten. Counting for our stops and all that, we’ve certainly covered sixty miles if we have one.”

“I agree with you, Jack,” said Josh; “George is only saying that to be contrary.”

“Oh, I am, eh?” grinned George, who seemed to take especial delight in stirring Josh up.

“It’s been a pretty good day for August, with the sun shining overhead most of the time, and not so very hot at that,” Buster continued. “There’s no sign of such a thing as a storm that I can see—great guns! what in the mischief can that queer-looking thing be over yonder? Do they have birds shaped like a fat cigar in the Danube country?”

Of course, every one immediately twisted his head around to take a look, and all sorts of exclamations announced that they were about as much astonished as Buster.

Low down toward the horizon they saw an object outlined against the sky that was undoubtedly moving, for they could notice that it passed a small cloud with considerable speed. Just as Buster had said, it looked very much in the distance like a fat cigar, and was of a neutral tint, not very easily distinguished against the heavens.
