Yes, little Minnie and her cousin Bertie have quite made up their minds to have a splendid collection of butterflies. They have been reading all about it in a book which their uncle, who is a professor at the Museum, has sent them. In this beautiful book they have learnt all about it—how to chase the butterflies, and how to catch them, and how to arrange them in glass cases when they are caught. Everything they want is ready for them. Their uncle has sent with the book two butterfly-nets; a pretty case filled with crooked scissors, tweezers, pincers, and all sorts of sharp steel instruments; a pretty box, at the bottom of which are little round pieces of cork, glued in rows, with long large-headed pins to run through the butterflies; and another little box, with a lot of small squares of glass, which are to be put over their wings to keep them open, and prevent them from fluttering and beating about.
