She came in the early morning, accompanied by her sister, and her
face wore a sad and resigned expression. After sweeping and dusting
the shop and drawing the blinds she opened the glass case and took
out a hat.

But when she saw a tiny gray mouse nestling among the ribbons and
laces she gave a loud shriek, and, dropping the hat, sprang with one
bound to the top of the table. The sister, knowing the shriek to be
one of fear, leaped upon a chair and exclaimed:

"What is it? Oh! what is it?"

"A mouse!" gasped the milliner, trembling with terror.

Popopo, seeing this commotion, now realized that mice are especially
disagreeable to human beings, and that he had made a grave mistake

discovered them sitting upon the branches of a big chestnut tree and
singing gayly.

When they saw the knook the birds cried:

"Thank you, Popopo. Thank you for setting us free."

"Do not thank me," returned the knook, "for I have come to send you
back to the millinery shop."

"Why?" demanded a blue jay, angrily, while the others stopped their
songs.

"Because I find the woman considers you her property, and your loss
has caused her much unhappiness," answered Popopo.

"But remember how unhappy we were in her glass case," said a robin
redbreast, gravely. "And as for being her property, you are a knook,
and the natural guardian of all birds; so you know tha
