Agonies indeed Brinnaria suffered in her efforts to live up to Causidiena’s ideas of what she should be. On the whole she succeeded pretty well and committed few errors of deportment. Outwardly she controlled herself from the first; for, before her first cowed sensations had worn off, her adoration of Causidiena had gained full sway over her. Yet inwardly she suffered more and more acutely as time went on, partly feeling that she must burst out in spite of herself, partly dreading that she would.

At last, after many days, she perpetrated her first and most undignified prank. It was a terrific occurrence, judged by the standards of the Atrium.

The great peristyle of the House of the Vestals, including nearly three-fourths of the whole courtyard, was beautified with a splendid double colonnade, two tiers of pillars, one above the other, the lower of delicately mottled Carystian marble wavily veined with green streaks varying its whiteness, the upper of coral-red brecchia. Midway of the court was a tank lined with marbles and always filled with clear water.

One morning Meffia, walking about the court, in her irritatingly aimless fashion, passed between Brinnaria and the edge of the tank. There was no earthly reason for her so doing, as Brinnaria was barely a yard from the margin of the pool, and on the other side of Brinnaria was the ample expanse of the pavement of the spacious court.

Brinnaria was exasperated by Meffia’s proximity, by her lackadaisical manner, by her shambling gait, by her sleep-walking attitude, most of all by the peculiar thin, sour odor which Meffia exhaled. At the sight of Meffia’s elaborately disagreeable demeanor of isolation, all Brinnaria’s natural self began to boil in her; at the whiff which assailed her nostrils she boiled over, all her uncurbed instincts surging up at once. She put out one foot and gave Meffia a push.

Meffia, with a squall and a great splash, fell into the tank.

She not only fell in, but she went under the water.

She went under and did not come up.

For an instant Brinnaria thought she was shamming to scare her; but, in a twinkling she realized that Meffia had fainted.

Promptly she plunged in and rescued her victim.
