Oh! to think that he should actually let her come as near to him as that! He knew nothing in the world would make her put out her hand toward him or startle him in the least tiniest way. He knew it because he was a real person--only nicer than any other person in the world. She was so happy that she scarcely dared to breathe. The flower-bed was not quite bare. It was bare of flowers because the perennial plants had been cut down for their winter rest, but there were tall shrubs and low ones which grew together at the back of the bed, and as the robin hopped about under them she saw him hop over a small pile of freshly turned up earth. He stopped on it to look for a worm. The earth had been turned up because a dog had been trying to dig up a mole and he had scratched quite a deep hole. Mary looked at it, not really knowing why the hole was there, and as she looked she saw something almost buried in the newly-turned soil. It was something like a ring of rusty iron or brass and when the robin flew up into a tree nearby she put out her hand and picked the ring up. It was more than a ring, however; it was an old key which looked as if it had been buried a long time.
