There was a bunch of cottonwoods at some little distance ahead, the location of which Perk had pointed out to his mate before settling down in his seat but if all went well Jack calculated to be able to clear them in good shape—did it seem necessary he could swerve slightly to the right, and have a clear field for the take-off.

There was a little shouting as the friendly plane started to taxi along, but of course this was smothered by the increasing roar of exhaust and spinning propeller. Faster and faster they scurried onward, and then started to rise on an angle just sufficient to nicely clear the tops of the cottonwoods; when Jack jazzed his motor, to find it running as “sweet as a purring cat.”

So they departed only a short time after making that landing which humanity had demanded and in times to come the little episode was likely to afford both aviators more or less satisfaction, in that they had “seen their duty and done it,” as Perk would say in his whimsical way.

As they continued on their way Perk found himself wondering if this interesting adventure was destined to be a sample of other equally thrilling happenings in store for them the further they dipped into the great game that had been laid at their door by the powers that be at Washington.

Whenever he came to thinking of the audacity shown by Slippery Slim in virtually defying all the authority of the Government, Perk would feel his dander rising as if in great indignation.

“Huh!” he at one time told himself, being rather fond of thus communing, as his thoughts ran on, “we’ll call his bluff just the same, the scaly ol’ gila monster, you wait an’ see. Thinks he’s the whole works, the boss man-handler, does he, just ’cause he’s outguessed a number o’ the boys. This time he’s due to find himself up against guys o’ the right size, who’ll jerk him down off’n his high perch in a jiffy, or I miss my ticket.”

So Perk kept on boasting in his customary fashion, possibly to keep his mind on the subject. Jack was paying little attention to side issues just then for he knew his pal’s peculiarities, and short-comings as well and having “exhausted his boiler” Perk presently lapsed into utter silence.

They had climbed to a fairly high ceiling, and caught only occasional fugitive glimpses of the earth far below, when the moon chanced to break through the banks of clouds, which intervals became less and less frequent, Jack noticed.

He did not altogether fancy the looks of the heavens, by degrees becoming more and more overcast; still, this might after all mean next to nothing and their business was to keep steadily on their way as if things were bound to come out all right.

It was now drawing well on toward midnight, and they had placed hundreds of miles between the city of their recent stay and themselves. Long since Perk had taken what proved to be his last glimpse of the vast gulf as seen far away toward the south, when the night was brightly illuminated, with the moon’s silvery rays shining on the glistening waters, and making a picture that even appealed to Perk’s rugged nature—after that all he was able to make out was the monotonous level plains that lay in every quarter, as though the whole earth consisted of this same stock country.
