Minnie’s mamma, who is almost like a mamma to Bertie too, though she is only his aunt, would be very glad to see her little ones fond of natural history, but still she does not seem quite pleased with their uncle’s idea in sending them, not only the pretty book, but the nets and the sharp, dreadful-looking steel things which they are to use in making their collection. She shook her head rather sadly when she saw the pretty nets which were to stop the butterflies from flying about so happily, and the pins and tweezers which were to turn them into lifeless specimens in a glass box.
