'Put your hand in, and find out. Here, Dora, you can try the other
pocket.'

2. In went two hands, and out came little hard lumps, each wrapped in
paper. The children laid them on the table in a row, and wanted to know
what they were.

[Illustration: 'What have you in your pockets, father?']

3. They were not nuts, nor marbles, and not quite like stones. They were
all about the same size, but one was very heavy. Harry and Dora held it
in their hands to feel how heavy it was.

4. 'That is a bit of lead,' said their father. 'Which do you think is
the next in weight?'

'This red one. It is a good deal lighter, though!'

'That is called copper. Now, what comes next?'

5. They were not sure, but thought that iron came next, and then tin,
and then zinc. Their father told them these names as they went on. He
told them also that all these things were metals, and had been dug out
of the earth.

6. 'Suppose we make a box to keep them in?'

'Oh yes!' cried both.
