It is related that King Sigurd one day was to give the emperor a feast, and he ordered his men to provide sumptuously all that was necessary for the entertainment; and when all things were provided which are suitable for an entertainment given by a great personage to persons of high dignity, King Sigurd ordered his men to go to the street in the city where firewood was sold, as they would require a great quantity to prepare the feast.
They said the king need not be afraid of wanting firewood, for every day many loads were brought into the town. When it was necessary, however, to have firewood, it was found that it was all sold, which they told the king.
"Go and try if you can get walnuts. They will answer as well as wood for fuel."
They went and got as many as they needed. Now came the emperor, and his grandees and court, and sat down to table. All was very splendid; and King Sigurd received the emperor with great state, and entertained him magnificently.
When the queen and the emperor found that nothing was wanting, she sent some persons to inquire what they had used for firewood; and they came to a house filled with walnuts, and they came back and told the queen.
"this is a magnificent king, who spares no expense where his honour is concerned."
She had contrived this to try what they would do when they could get no firewood to dress their feast with.
