"Is that so?" said Johnny. "I should like to know your cousin very much. Is he coming to see you this summer?"
"No: he has gone up into the mountains with his folks."
"What is your 'Play-Book of Science'?" inquired Pierre.
"You wouldn't think it much of a play-book if you could see it; it is one of the deepest books I have; and the experiments are most of them so elaborate that I haven't been able to try them yet, and can't until I get a good deal older. It is a book my father had when he was a boy, and goes into philosophy and chemistry pretty thoroughly. It is very interesting, and has four hundred and seventy pictures illustrating the experiments and principles. There are over four hundred pages of pretty fine print."
"Who is the author of it?"
"Professor Pepper."
"Oh, yes! An English professor. I know. It must be an excellent work."
"And I have the 'Play-Book of Metals,' by the same author."
"Who are the publishers of the books?"
"Routledge & Sons, London."
