The ring tossed with excitement. Bets were roared from brazen throats; those on the outskirts of the crowd fought to get a look. And in the open centre of the tumult a furry ball rolled and bit and squealed and made bloody sport for those who gloated over it.

A yell, half exultation, half anger, broke from a dozen throats. The black rat tore himself loose and fled back toward Balbus; the gray stood in the middle of the ring, triumphant. Both were badly mangled and drenched with blood, but the black was craven. The followers of the gray roared their triumph. Balbus seized his rat and flung him back into the fight, almost on top of the gray, which instantly fastened on him.

But, plainly, the black had had enough. It could be seen that he no longer attacked; was all on the defensive, trying only to escape. Again he broke away and crawled toward safety. The ring howled with mingled derision and delight. Balbus, cursing, his face congested with rage, again threw him back, and again the vicious gray fell upon him with teeth and claws.

"Give thy sandals quickly, Chilo!" a voice shouted above the racket. "The black is down!"

He was, and the gray on top of him, bloodily victorious.

"Peractum est!" Nicanor shouted, in the language of the arena; and sprang to his feet and caught up his bloody pet and held him high in triumph. But Balbus, his face aflame with fury, strode to where the black rat lay still twitching, and stamped the heel of his iron-shod sandal upon its head with such force that its brains and blood were spattered.

"It was no fair fight!" he cried, turning on those who jeered him. "That gray beast wrought by magic. Thou hast played a trick!" He shook his fist in Nicanor's face, glaring.

Nicanor backed away with a laugh. It taunted Balbus beyond endurance; he lunged forward, his fists clenched. In an instant there had been battle, on which men would have bet as eagerly as on the combat ended. But there was a sudden clamor of guards' whistles; a rush from the ladders, and overseers fell upon the crowd with hissing lashes that left their marks on backs and thighs. The ring broke up, as men fled like sheep and were whipped back to their posts.

Soon there was nothing heard but the endless tapping of picks, the thud of falling earth, and the voices of overseers and the foremen of the gangs. But Balbus, each time he passed with laden basket the spot where Nicanor stood tirelessly wielding his heavy pick, scowled at him blackly and muttered oaths of vengeance. For he was of those who must be taught, by many ungentle lessons, that one must know how to lose as well as how to win.
