“No, no, ma'am; it's I'm at his service. I'm just a-going out with my own cab, and if he likes to come with me, he shall drive my old horse till he's tired.”

“It's getting rather late for him,” said his mother thoughtfully. “You see he's been an invalid.”

Diamond thought, what a funny thing! How could he have been an invalid when he did not even know what the word meant? But, of course, his mother was right.

“Oh, well,” said Mr. Stonecrop, “I can just let him drive through Bloomsbury Square, and then he shall run home again.”

“Very good, sir. And I'm much obliged to you,” said his mother. And Diamond, dancing with delight, got his cap, put his hand in Mr. Stonecrop's, and went with him to the yard where the cab was waiting. He did not think the horse looked nearly so nice as Diamond, nor Mr. Stonecrop nearly so grand as his father; but he was none, the less pleased. He got up on the box, and his new friend got up beside him.

“What's the horse's name?” whispered Diamond, as he took the reins from the man.

“It's not a nice name,” said Mr. Stonecrop. “You needn't call him by it. I didn't give it him. He'll go well enough without it. Give the boy a whip, Jack. I never carries one when I drive old——”

He didn't finish the sentence. Jack handed Diamond a whip, with which, by holding it half down the stick, he managed just to flack the haunches of the horse; and away he went.

“Mind the gate,” said Mr. Stonecrop; and Diamond did mind the gate, and guided the nameless horse through it in safety, pulling him this way and that according as was necessary. Diamond learned to drive all the sooner that he had been accustomed to do what he was told, and could obey the smallest hint in a moment. Nothing helps one to get on like that. Some people don't know how to do what they are told; they have not been used to it, and they neither understand quickly nor are able to turn what they do understand into action quickly. With an obedient mind one learns the rights of things fast enough; for it is the law of the universe, and to obey is to understand.

“Look out!” cried Mr. Stonecrop, as they were turning the corner into Bloomsbury Square.
