“And the meaning?” queried the attentive Kenyon, without showing any of his customary signs of incredulity or dissent.

“The hieroglyphic which is such a stumbling-block to you, Kenyon, simplified, stands thus:—

“I. v. LIII,

“and the meaning is merely ‘Richard Grenville.’ It was a secret sign between my cousin and myself when we were mere schoolboys, and the simile was drawn from the memorable sea-fight in the reign of good Queen Bess, when Sir Richard Grenvil—God rest him for a gallant gentleman!—‘with one small ship and his English few,’ fought for a day and a night with fifty-three Spanish galleons. As a boy, my cousin—though no descendant of the hero—was passionately devoted to this page of history, and used to sign himself ‘1 versus 53,’ and so, by yonder sign, I know he lives, and lives looking for me to find him, and to read the hand he wrote, which to all others would, of course, be utterly unintelligible.” And Leigh again set to and fairly danced with joy and excitement at this truly singular and fortunate discovery.

Whilst being thoroughly surprised, Kenyon could but congratulate himself at seeing the hall-mark of absolute accuracy thus unexpectedly stamped upon every link in the chain of his pet theory, and both men were now equally eager to descend the rocky pathway—the reason for the existence of this last being, under the circumstances, a positive enigma to them—and recommence their search for the lost one on the other side of the kloof.

After a hasty breakfast, however, the pair decided that, as they were already on the spot, it would be best to thoroughly satisfy themselves regarding their own side of the chasm, more especially as, by the time they had descended the rocky pathway and called at the camp, it would have been too late to attempt the ascent of the cliffs, which were now believed by them to provide a rampart for the enemy, and a prison for their friend.

The twain, therefore, scrambled down the rocks facing towards the north, and quickly found, as Kenyon had predicted, that the position on that side was rendered altogether inaccessible by the presence of the swamp, which just here was very much in evidence. In every direction, as far as the eye could reach, it spread itself out brightly verdant and inviting in the sunshine, but utterly treacherous and unstable, and the nearer it approached to the rocks the more palpable did the fraud appear, as, at the point where the stony ground impinged upon the veldt, the swamp was little better than stagnant pools of slimy, evil-smelling water, overgrown with reeds and rushes.

Re-ascending the rocks, Leigh and Kenyon sheltered themselves in the woods from the rays of the vertical sun, utilising their time by making themselves, as they believed, thoroughly conversant with the place, and when the day began to grow towards evening, they left the bush-clothed heights, and again turned their faces towards the camp.

Just as the pair commenced the descent of the narrow rocky path Kenyon suddenly paused, and drew in his breath with an angry hiss, and following the direction of his eager gaze, Leigh looked towards their tent, which was plainly in view, about a mile away as the crow flies.

From the height at which our friends stood, they had, of course, an unrestricted view of the plain stretched out before them, and everything upon it, and there, some two hundred yards from the camp, and clearly outlined against the veldt upon which he lay stretched, was the unwelcome figure of an unmistakable spy, who, so far as he could be made out at that distance, wore the garments of a white man.
