I knew by the smell.
All human beings have a strong smell to a dog, even though they mayn't notice it themselves.

Mrs.Morris never knew how she bothered me by giving away Miss Laura's clothes to poor people.

Once, I followed her track all through the town, and at last found it was only a pair of her boots on a ragged child in the gutter.
I must say a word about Billy's tail before I close this chapter.

It is the custom to cut the ends of fox terrier's tails, but leave their ears untouched.

Billy came to Miss Laura so young that his tail had not been cut off, and she would not have it done.
One day Mr.Robinson came in to see him and he said, "You have made a fine-looking dog of him, but his appearance is ruined by the length of his tail." "Mr.Robinson," said Mrs.Morris, patting little Billy, who lay on her lap, "don't you think that this little dog has a beautifully proportioned body ?" "Yes, I do," said the gentleman.
