I stopped him, as he was dragging it off by the tail to show me how it was used, for I was half afraid the 'eerie' feeling might go off before we had finished the garden, and in that case I should see no more of him or Sylvie. "I think the best way will be for you to weed the beds, while I sort out these pebbles, ready to mark the walks with."

"That's it!" cried Bruno. "And I'll tell oo about the caterpillars while we work."

"Ah, let's hear about the caterpillars," I said, as I drew the pebbles together into a heap and began dividing them into colours.

And Bruno went on in a low, rapid tone, more as if he were talking to himself. "Yesterday I saw two little caterpillars, when I was sitting by the brook, just where oo go into the wood. They were quite green, and they had yellow eyes, and they didn't see me. And one of them had got a moth's wing to carry----a great brown moth's wing, oo know, all dry, with feathers. So he couldn't want it to eat, I should think---- perhaps he meant to make a cloak for the winter?"

"Perhaps," I said, for Bruno had twisted up the last word into a sort of question, and was looking at me for an answer.

One word was quite enough for the little fellow, and he went on merrily. "Well, and so he didn't want the other caterpillar to see the moth's wing, oo know----so what must he do but try to carry it with all his left legs, and he tried to walk on the other set. Of course he toppled over after that."

"After what?" I said, catching at the last word, for, to tell the truth, I hadn't been attending much.

"He toppled over," Bruno repeated, very gravely, "and if oo ever saw a caterpillar topple over, oo'd know it's a welly serious thing, and not sit grinning like that----and I sha'n't tell oo no more!"

"Indeed and indeed, Bruno, I didn't mean to grin. See, I'm quite grave again now."

But Bruno only folded his arms, and said "Don't tell me. I see a little twinkle in one of oor eyes----just like the moon."

"Why do you think I'm like the moon, Bruno?" I asked.

"Oor face is large and round like the moon," Bruno answered, looking at me thoughtfully. "It doosn't shine quite so bright----but it's more cleaner."

I couldn't help smiling at this. "You know I sometimes wash my face, Bruno. The moon never does that."

"Oh, doosn't she though!" cried Bruno; and he leant forwards and added in a solemn whisper, "The moon's face gets dirtier and dirtier every night, till it's black all across. And then, when it's dirty all over----so----" (he passed his hand across his own rosy cheeks as he spoke) "then she washes it."

"Then it's all clean again, isn't it?"

"Not all in a moment," said Bruno. "What a deal of teaching oo wants! She washes it little by little----only she begins at the other edge, oo know."

By this time he was sitting quietly on the dead mouse with his arms folded, and the weeding wasn't getting on a bit: so I had to say "Work first, pleasure afterwards: no more talking till that bed's finished."
