"Morning," they replied together.
"When is it warmest?"
"Noon," said Susie quickly.
"Now you are wrong," said Frank. "It is often warmer at one or two o'clock."
"Frank is right," said Uncle Robert. "How can we tell just how warm it is at any time?"
"If we had a thermometer," said Donald, "that would tell, but we haven't."
"There's one at the post office," said Frank, "but I never saw any one look at it unless it was very cold or very hot."
"Perhaps we can find one nearer than the post office," said Uncle
Robert. "Susie, would you know one if you saw it?"
Susie shook her head.
"I would," said Donald.
