It was a piece of paper--in fact, it was a piece of the letter she had printed for Martha to send to Dickon.

It was fastened on the bush with a long thorn, and in a minute she knew Dickon had left it there.

There were some roughly printed letters on it and a sort of picture.

At first she could not tell what it was.

Then she saw it was meant for a nest with a bird sitting on it.
