"The very thing!" replied Uncle Robert, well pleased. "You are always up early, Frank, so suppose you look at six in the morning, Susie at twelve o'clock, and Donald at six in the evening. How will that do? Then we shall have the record for the whole day."
"I think it will be such fun!" said Susie. "I wonder if our books will be very different."
"What makes you think they will be different?" asked Uncle Robert.
"It's always hotter at noon than it is at night or in the morning," said
Susie.
"Do you know," said Uncle Robert, "there are places all over the United States where such records are kept? They are published, and I am to have them sent to me every week."
"I wonder if ours will be like them," said Donald, turning over the pages of his notebook.
"Even if they should be different." said Uncle Robert, "they may be just as true."
"We'll get up early and start the shadow stick the first thing in the morning," said Frank, "so as to have it ready by noon."
"How do you know when it is noon?" asked Uncle Robert.
"We look at the clock," said Susie.
