Ryan's room, and not go out of it on any excuse until I come to fetch you, I will take you, though it is rather extravagant, for we shall have to go by omnibus.' 'Never mind, it will be my Saturday's treat,' said Vava; and the two set out for the City. Mrs. Ryan held up her hands at sight of them. 'There's brave young ladies! Not one of the young ladies of Philips's downstairs have come yet, and three of them that live some way off have sent telephone messages to say it's too thick their way, and they want to be excused.'
