At five minutes to three, Bet bent her head over her book, declaring that she would not look at the clock again until it was three. Then, when she was certain that the minute hand must be pointing to twelve, she looked up and gave a gasp. Only one minute had gone by! How the time dragged!

"It's a good thing I carry my key with me, or we would have lost about ten minutes," said Shirley and she unlocked the door and let the girls in.

"Here's your deer, Shirley. Put him in the bath and let's have a look at him. I'm first!"

"You've earned that right," Shirley answered.
