Frank, however, seemed to view the situation more gravely than his light-hearted brother. As has been said, Frank, while but little older in point of years possessed a temperament diametrically opposed to the mercurial nature of his younger brother. He weighed things, and indeed in the construction of the Golden Eagle, while Harry had suggested all the brilliant imaginative points, it had been the solid practical Frank who had really figured out the abstruse details of the wonder-ship’s structure.

Despite this difference of temperament—in fact Harry often said, “If Frank wasn’t so clever and I wasn’t so optimistic we’d never have got anywhere,”—in spite of this contrast between the two there was a deep undercurrent of brotherly love and both possessed to the highest degree the manly courage and grit which had tided them over many a discouraging moment. Nor in the full tide of their success, when people turned on the street to point them out, were either of the boys at all above recognizing their old playfellows and schoolmates as has been known to be the case, it is said, with other successful boys—and men.

“I don’t know, Harry,” replied Frank at length to his brother’s enthusiastic reception of the news of the rebellion, “there are two sides to every question.”

“Yes, but Frank, think,” protested Harry, “we shall have a chance to see a real skirmish if only they keep at it long enough. Confound it though,” he added with an expression of keen regret, “the paper says it’s another ‘comic opera revolution.’”

“I wouldn’t be too sure of that, Harry,” replied Frank, seriously. “When father was north last he told us, if you recollect, that a Central American revolution was not by any means a picnic. In the battle in which the United States of Colombia drove the Venezuelans from their territory, for instance, there were ten thousand dead left on the field.”

Frank halted under one of the wire-screened lights screwed into the bulkhead beside which they had been pacing to let the light of the incandescent stream brighter upon his paper. He scanned the page with rapid eye and suddenly looked up with an exclamation that made Harry cry:

“What’s the trouble, Frank?”

“Well, it looks as if on the day we are sailing for Nicaragua that that country is monopolizing the news to the exclusion of the important fact that ‘The Boy Aviators’”—he broke off with a laugh.

“Hear! hear,” exclaimed Harry, striking a pose.

“—I say,” continued Frank, “that it seems as we haven’t a look in any more. The country for which we are bound has the floor. Listen—”
