Grandfather, to listen.

Grandfather played six tunes.

Then Grandmother said,

"Why don't we go to the woods to hear the band play?"

"No reason at all," said Grandfather. So very soon they were on
their way to a grove on the edge of the town.

In the grove a band was playing; and just as the Twins and
Grandfather and Grandmother came up, it began to play the national
hymn of Holland. All the people began to sing. There were a great
many people in the grove, and they all sang as aloud as they
could; so there was a great sound. Grandfather and Grandmother
and Kit and Kat all sang too; for they all knew every word of the
hymn.

This is what they sang:

Let him in whom old Dutch blood flows,
Untainted, free and strong;
Whose heart for Prince and Country glows,
Now join us in our song;
Let him with us lift up his voice,
And sing in patriot band,
The song at which all hearts rejoice,
For Prince and Fatherland,
For Prince and Fatherland.
