“They are like little pieces of carved ivory all shaped alike,” Frank replied.

“Yes, but that does not give us a very clear idea of their shape,” observed his uncle. “Come on, Tom.”

“They are like little Indian clubs with the handles cut off, only they are beautifully marked with long, slender ridges and cross bars.”

“That is really a very good account of them, Tom. They are arranged in patches. Count and let me know how many eggs are in each bunch.”

The boys counted all the groups of eggs, and found that there were eight eggs in some, nine in others, but that most of them contained ten or more.

“Now, how many egg patches are there?” asked Uncle George.

“There are seven patches on my leaf,” said Frank.

“And ten on mine,” added Tom.

“That is about one hundred and fifty eggs altogether,” said Uncle George.

“Has each of these bunches of eggs been laid by one butterfly?” asked Frank.
