That question served to recall the professor to more material points, and, after a keen, sweeping look around, he nodded assent.

“Yes, as soon as I can discover or secure a fair chance. I wish to see more—I must secure a fairer view of the—of yonder place.”

“Will it not be too dangerous, though? Not for us, especially, uncle, but for the aerostat? Even if these be not the people you imagine—”

“They are past all doubt a remnant of the ancient Aztecs. Yonder lies the true Lost City, and we are—oh, try to comprehend all that statement means, my lads! Picture to yourselves what boundless fame and unlimited credit awaits our report to the outer world! The benighted world! The besotted world! The—the—”

“While we'll form the upsotted world, or a portion of it, without something is done,—and that in a howling hurry, too!” fairly spluttered Waldo, as the again neglected air-ship sped swiftly towards a more elevated portion of that earth, part of the tall hill-crest which acted as nature's barricade to yonder by nature depressed valley.

“Time enough, lad, time enough, since we are going to land,” coolly assured the professor, deftly manipulating the steering-gear and still curying around those tree-crowned hills. “If we are really hunted after, 'twill naturally be in the quarter of our vanishment, while by alighting around yonder, nearly at right angles with our initial approach, we will have naught to fear from the—the Aztecan clans!”

Clearly the professor had settled in his own mind just what lay before them, and nothing short of the Lost City of the Aztecs would come anywhere near satisfying that exalted ideal. And, taking all points into full consideration, was there anything so very absurd in his method of reasoning, or of drawing a deduction?

Still, that exaltation did not prevent uncle Phaeton from taking all essential precautions, and it was only when an especially secure landing-place was sighted that he really attempted to touch the earth.

Fully one-half of that wide circuit had been made, and as nothing could be detected to give birth to fears for either self or air-ship, the aeronauts skilfully landed their vessel with only the slightest of jars. It was a well-screened location, where naught could be seen of the flying-machine until close at hand, yet so arranged as to make a hasty flight a very easy matter should the occasion ever arise.

Not until the landing was effected and all made secure, did Professor Featherwit speak again. Then it was with gravely earnest speech which suitably affected his nephews.
