"Rather a late visitor," said Father, "and rather an inconsiderate one if this quite Eastern welcome of him includes us all catching our death of cold. No, Ridgie, I'm afraid he will have to knock."
"But, Father, I'm not sure he can knock."
"Then ring," suggested their parent, "nice new electric bell I've just had fixed up. He's only got to push the button."
"Perhaps he doesn't understand about electric bells," objected Ridgwell.
"Your friend seems a trifle old-fashioned," observed Father, good-naturedly.
"And then," said Ridgwell, "his paw is so big he might never find the bell-push."
"I see; a dog, eh?"
"No, bigger than a dog, much."
"Well, then, say a donkey."
"No, Father, bigger than a dog, and not so big as a donkey."
