[Illustration: He opened the case and used the whole thing as a garden spade] "He does grow," said Anthea. "Doesn't 'oo, precious?" "Me grow," said the Lamb cheerfully--"me grow big boy, have guns' an' mouses--an'--an'"---- Imagination or vocabulary gave out here. But anyway it was the longest speech the Lamb had ever made, and it charmed everyone, even Cyril, who tumbled the Lamb over and rolled him in the moss to the music of delighted squeals. "I suppose he'll be grown up some day," Anthea was saying, dreamily looking up at the blue of the sky that showed between the long straight chestnut-leaves. But at that moment the Lamb, struggling gaily with Cyril, thrust a stout-shod little foot against his brother's chest; there was a crack!--the innocent Lamb had broken the glass of father's second-best Waterbury watch, which Cyril had borrowed without leave. "Grow up some day!" said Cyril bitterly, plumping the Lamb down on the grass. "I daresay he will--when nobody wants him to. I wish to goodness he would"-- "_Oh_, take care!" cried Anthea in an agony of apprehension. But it was too late--like music to a song her words and Cyril's came out together-- Anthea--"Oh, take care!" Cyril--"Grow up now!" The faithful Psammead was true to its promise, and there, before the horrified eyes of its brothers and sisters, the Lamb suddenly and violently grew up. It was the most terrible moment. The change was not so sudden as the wish-changes usually were. The Baby's face changed first. It grew thinner and larger, lines came in the forehead, the eyes grew more deep-set and darker in colour, the mouth grew longer and thinner; most terrible of all, a little dark mustache appeared on the lip of one who was still--except as to the face--a two-year-old baby in a linen smock and white open-work socks. "Oh, I wish it wouldn't! Oh, I wish it wouldn't! You boys might wish as well!" They all wished hard, for the sight was enough to dismay the most heartless. They all wished so hard, indeed, that they felt quite giddy and almost lost consciousness; but the wishing was quite vain, for, when the wood ceased to whirl round, their dazed eyes were riveted at once by the spectacle of a very proper-looking young man in flannels and a straw hat--a young man who wore the same little black mustache which just before they had actually seen growing upon the Baby's lip. This, then, was the Lamb--grown up! Their own Lamb! It was a terrible moment. The grown-up Lamb moved gracefully across the moss and settled himself against the trunk of the sweet chestnut. He tilted the straw hat over his eyes. He was evidently weary. He was going to sleep. The Lamb--the original little tiresome beloved Lamb often went to sleep at odd times and in unexpected places. Was this new Lamb in the grey flannel suit and the pale green necktie like the other Lamb? or had his mind grown up together with his body?
