There was silence: Roy broke it at last by saying with knitted brow, "I'd rather be a maker than a mender, but lots of people aren't either."

"Quite right," nodded the old man; "most folk are breakers."

"I wish I was as clever as you," said Dudley; "you mend umbrellas, and kettles, and plates, and windows, and gates, and all sorts. How did you learn?"

"Well, I ain't ashamed of owning that my father was just a travelling tinker, and when I was a little fellow I used to go round with him and see him do most things. It was from travelling through the country I learned to love it so. And my father, he was a thoughtful man, and when I used to ask where the tin came from, and where the iron and where the lead, he took to learning of it up so that he could answer me; and then I came to find that most of our comforts come from underground, and so I fell to digging. Ah, youngsters, earth is a wonderful treasure house!"

The boys knew the shelf well; as though apparently it was just a row of tinware for sale, many a pot and pan held treasures that geologists would have given a great deal to possess.

"I know, it's a Roman hammer," shouted out Dudley.

"It's a Saxon jug," suggested Roy.

"It's part of a jaw of a mammoth many thousands of years old, and there are two teeth in perfect preservation," old Principle said solemnly.

"Where did you find it?"
