Adam has forbidden the children to ask any more questions about the names of the animals, Cain having exasperated him by asking how much a guinea was worth.
"About five dollars," said Adam.
"Gee!" cried Cain.

"You must have got stung on the guinea-pigs, then.
They're dear at a dollar a dozen." * * * * * It may interest modern readers who seem to have created a demand for what is known as the Mother-in-Law joke that this style of humor found its origin in an early remark of Abel's, if his mother's Diary is to be believed.

A visitor once interrupted him in the midst of a ball game that he was playing with Cain and a number of his Simian friends, to ask him how his grandmother was.
"Never had one," replied Abel, with a grin.
"Poor boy," sympathized the visitor.

"And don't you wish you had ?" "Yes," said Abel.

"I think a Mother-in-Law around the house would have done Pa good!" I will close my remarks concerning these famous boys with a little poem which their mother had clipped from an Egyptian paper and pasted in her book.
