The glimpse grew a little more definite.

“I should like that, too,” said Mrs. Mainwaring. “But my husband’s work keeps him in London, and I do not get away very often. Shall we go upstairs to tea?”

As they turned, Mrs. Mainwaring cast one glance at the great cartoon. For the moment, infinitesimal in duration, her neat smooth porcelain face grew hostile and malevolent.

No sooner did Silvia appear in the doorway of the little drawing-room facing the street, than Mr. Mainwaring, to her immense surprise, bounded from his seat, chasséed across the room to her, and fell on his knees before her.

“Behold me in an attitude of abject entreaty!” he said. “Your mother, subject to your acquiescence, dear Miss Silvia, has asked me to attempt to use my best endeavours, feeble as they may be, to render you the eager homage of an artist’s skill. She has asked me, subject to your consent, I repeat, to paint your portrait for her.”

Even as he spoke there came the quick light step on the stairs, the identity of which Silvia, seldom as she had heard it, knew with a certainty that surprised her, and Peter came in.

“Kneel, Peter, my dear,” said his father, enjoying himself tremendously and putting up hands of supplication. “Maria, my angel, I beseech you to kneel too. We are entreating Miss Silvia; we are urging the sacred claims of Art.

Silvia gave a laugh of sheer amusement at this ludicrous situation. Amusement was the only possible solvent for it.

“Oh please, let nobody kneel!” she said. “And you, Mr. Mainwaring, please get up. Yes, of course, if my mother wishes it, and if Mr. Mainwaring will be very patient and tell me what to do——”

He bounded up again, ecstatic at the granting of his petition.
