"Of course they'll be sick," declared Mr. Hildreth. "Animals and people need work to keep them well. Ask your brother."

"Then I'll let my animals work just enough," said Sarah thoughtfully. "Not too much, but just enough. And maybe I'll let Warren plow with the horses."

"I would, if I were you," agreed Mr. Hildreth. "You work pretty hard yourself, don't you, Sarah?"

Sarah stared at him suspiciously. Apparently he was serious.

"Of course," continued Mr. Hildreth, "you call it play. But when I see you flying over this farm and trying to be in two places at once and cram half a hundred experiences into one short day, I think you work as hard as I do. Maybe harder. Don't you ever get tired, Sarah?"

"When I go to bed," responded that active person. "But I'm not tired when I first go," she added hastily. "Mother or Hugh or Winnie are always making me go to bed before I'm sleepy. I want to study the insects on the lawn, but how can I when I have to go to bed?"

"You're not the first person who has wanted to turn night into day," said Mr. Hildreth calmly. "It's lucky for some of us that you're not successful. If we had to keep an eye on you all night, Sarah, as well as during the waking hours, think how little else we'd get done."

Sarah had a shrewd suspicion that he was laughing at her. She turned to go.

"Wait a minute—wouldn't you like a pet?" said the farmer quickly.

"Oh, yes!" replied Sarah.
