The children were puz-zled. They looked at one another, and sat very still for a little while. Then a brave, bright boy spoke up and said,—
"It belongs to the veg-e-ta-ble kingdom, sir."
"Why so, my lad?" asked the king.
"It is the fruit of a plant, and all plants belong to that kingdom," said the boy.
The king was pleased. "You are quite right," he said; "and you shall have the orange for your prize."
He tossed it gayly to the boy. "Catch it if you can!" he said.
Then he took a yellow gold piece from his pocket, and held it up so that it glit-tered in the sunlight.
"Now to what kingdom does this belong?" he asked.
Another bright boy answered quick-ly, "To the min-er-al kingdom, sir! All metals belong to that kingdom."
