“'Twould take a strong light and mighty keen eyes to see it at all, and even if a body should happen to notice it, he'd reckon 'twas a bit of smut, or the like,” generously declared Waldo.

Under less trying circumstances, Bruno might have answered in kind, but now he merely smiled at the jester, then turned again to receive the earnest cautions let fall for his benefit by the professor.

Above all else, he was to steer clear of fighting, and, without he saw a fair chance of winning speech with the white women, he was to keep in such hiding as Ixtli might furnish, trusting the young Aztec to post the Children of the Sun as to what was in the wind.

Tremulous, almost incapable of coherent speech, so intense was his agitation, Cooper Edgecombe sent many messages to his loved ones, begging for one word in return. And if nothing less would serve—

His voice choked, and only his feverishly burning eyes could say the rest.

It was well past sunset ere the youngsters set forth from the rendezvous, accompanied a short distance by both Waldo and the professor; but the parting came in good time. It would be worse than folly to add to the existent perils that of possible discovery by some prowling Aztec who might work serious injury to them one and all.

That great bear-hide proved a tax upon their strength, even though the bullet-riddled head-piece had been carefully cut off and buried, lest those queer holes tell a risky tale on close examination; but Ixtli, as well as Bruno, was upborne by an exaltation such as neither had known before this hour.

There was nothing worse than the natural obstacles in the way to be overcome, and, knowing every square yard of ground so thoroughly, Ixtli chose the most practicable route to that hill-encircled town.

The stony pass was followed to the lower level, and the young adventurers had drawn fairly near the first buildings ere encountering a living being; and then ample time was given them for meeting the danger.

A low-voiced call sounded upon the night air, and Ixtli responded in much the same tone. Bruno, of course, was utterly in the dark as to what was being said, but he still held perfect faith in his copper-hued guide, and left all to the son of Aztotl.
