Buff was struggling into his overcoat, watched (but not helped) by Thomas and Billy, but when he heard of his sister's plan he at once took it off again and said he would make one of the party.
Thomas looked at his friend coldly.
"Mamma says," he began, "that's it's a very daft-like thing the way you get taken to places and miss school. By rights I should have got staying at home to-day with my gum-boil."
"Poor old Thomas!" said Elizabeth. "Never mind. You and Buff must both go to school and grow up wise men, and you will each choose a chocolate out of Mr. Townshend's box for a treat."
The sumptuous box was produced, and diverted Buff's mind from the expedition; and presently the three went off to school, quite reconciled to attempting another step on the steep path to knowledge.
"Isn't Thomas a duck?" said Elizabeth, as she returned to the table after watching them go out of the gate. "So uncompromising."
"'Mamma' must be a frank and fearless commentator," said Mr. Townshend.
"Thomas makes her sound so," Elizabeth admitted. "But when I meet her—I only know her slightly—she seems the gentlest of placid women. Well, can you be ready by eleven-thirty? Of course I want to go. I'm looking forward hugely to seeing Glasgow through your eyes. Come and write your letters in the drawing-room while I talk to Marget about dinner."
Punctually they started. It was a bright, frosty morning, and the trim villas with their newly cleaned doorsteps and tidily brushed-up gardens looked pleasant, homely places as they regarded them from the top of a car.
"This is much nicer than motoring," said Elizabeth. "You haven't got to think of tyres, and it only costs twopence-ha'penny all the way."
