After a while Bunny shut his eyes.
Then Billy shut his eyes, and they both fell fast asleep.

They slept such a long time that when they opened their eyes the sun
was just going to bed.

Bobby Squirrel was sitting in the maple tree over their heads.

"Have you seen Mrs. Duck?" asked Bunny.

"Oh, yes!" answered Bobby. "She walked along the path early this
afternoon."

"Well, well!" said Bunny. "I will try again to-morrow. I will ask
Bobtail to come with me. Perhaps he can keep awake."

The next day the three little rabbits sat under the maple tree to watch
for Mrs. Duck.

They waited and waited.

It was very warm in the field.

After a while the three little rabbits became sleepy.

Then Bobtail jumped up on his feet and began to hop around.

"Let's play tag," he said. "If we sit here in the sun we shall go to
sleep.

So the three rabbits played tag.

They ran round and round the maple tree. They ran back and forth along

When she had eaten all she wanted she went out of the yard and across
the road.

Then she walked back again along the path across the field.

When she came to the maple tree she saw Bunny and Bobtail and Billy.

And Bunny and Bobtail and Billy saw Mrs. Duck.

"Where are you going, now?" asked Bunny.

"I am going down to the brook," she said. "That is where my secret is."

"May we go with you?" asked Billy.

"Yes," said Mrs. Duck. "I will show you my secret if you will all

So the three little rabbits hopped along behind Mrs. Duck until they

The water in the brook was running over the stones and singing a sweet
little song.

Mr. Green Frog was sitting on a stone taking a nap in the warm sun.

"Now, follow me," said Mrs. Duck. "I will show you my secret."
