With screams of rage the circling Arabs lowered their spears to swoop upon the victor and save the vanquished if they might, but Menon flung his shield arm up in warning.

"Back!" he cried, "or by the crown of Ishtar will I slit his throat!"

The sons of the desert halted, as a steed is curbed, each poised for a savage thrust, each waiting in awesome dread for a thread of life to snap, while Boabdul Ben Hutt gazed upward into Menon's eyes, though the brand of fear burned not upon his cheek.

"Strike, dog!" he groaned, in the shame and anguish of defeat; but Menon tossed his sword away and stretched forth his hands that the fallen one might rise.

In silence stared the Bedouins; in silence Boabdul rose and looked in puzzled wonder on his conqueror.

"Assyrian," he asked at length, "why now is thy blade unstained, when a twist of fortune gave me over into thy hand?"

"My lord," spoke Menon solemnly, and yet with a certain twinkling of the eye, "I seek to seal a covenant with Arabia's Prince; not with Boabdul dead."

The Arabian had looked on death, and knew that the wine of life was sweet to him; so anger departed utterly, and humor seized him till he laughed aloud.

"Now by my father's beard," he cried, as he caught the Assyrian's hands in his and pressed them against his breast, "if Ninus keepeth faith as he chooseth messengers, right gladly will I call him Brother of my Soul!"

Then a mighty cheer arose, whose echoes rolled far out across the plains—a cheer for Ninus, lord of all Assyria—and another, louder, longer still, for the lion-hearted messenger. It had come upon the Arabs that Menon not once had sought to strike a fatal blow, but had stood before the desert's fiercest scimitar, undaunted, staking all upon his strength, and had spared where he might have slain.
