William was bored. He sat at his desk in the sunny schoolroom and gazed dispassionately at a row of figures on the blackboard.

“It isn’t sense,” he murmured scornfully.

Miss Drew was also bored, but, unlike William, she tried to hide the fact.

“If the interest on a hundred pounds for one year is five pounds,” she said wearily, then, “William Brown, do sit up and don’t look so stupid!”

William changed his position from that of lolling over one side of his desk to that of lolling over the other, and began to justify himself.

“Well, I can’t unnerstand any of it. It’s enough to make anyone look stupid when he can’t unnerstand any of it. I can’t think why people go on givin’ people bits of money for givin’ ’em lots of money and go on an’ on doin’ it. It dun’t seem sense. Anyone’s a mug for givin’ anyone a hundred pounds just ’cause he says he’ll go on givin’ him five pounds and go on stickin’ to his hundred pounds. How’s he to know he will? Well,” he warmed to his subject, “what’s to stop him not givin’ any five pounds once he’s got hold of the hundred pounds an’ goin’ on stickin’ to the hundred pounds——”

Miss Drew checked him by a slim, upraised hand.

“William,” she said patiently, “just listen to me. Now suppose,” her eyes roved round the room and settled on a small red-haired boy, “suppose that Eric wanted a hundred pounds for something and you lent it to him——”

“I wun’t lend Eric a hundred pounds,” he said firmly, “’cause I ha’n’t got it. I’ve only got 3½d., an’ I wun’t lend that to Eric, ’cause I’m not such a mug, ’cause I lent him my mouth-organ once an’ he bit a bit off an’——”

Miss Drew interrupted sharply. Teaching on a hot afternoon is rather trying.
