“That is the one evil of our country,” answered the invisible man. “Many large and fierce bears roam in the Valley of Voe, and when they can catch any of us they eat us up; but as they cannot see us, we seldom get caught.”

“Are the bears invis’ble, too?” asked the girl.

“Yes; for they eat of the dama-fruit, as we all do, and that keeps them from being seen by any eye, whether human or animal.”

“Does the dama-fruit grow on a low bush, and look something like a peach?” asked the Wizard.

“Yes,” was the reply.

“If it makes you invis’ble, why do you eat it?” Dorothy enquired.
