We pretended to be two caterpillars, and we would creep along the ground upon our stomachs and our knees and hunt for leaves to eat. After having done that for some time we played that we were very very sleepy, and we would lie down in a corner under the trees and cover our heads with our white aprons--we had become cocoons. We remained in this condition for some time, and so thoroughly did we enter into the role of insects in a state of metamorphosis, that any one listening would have heard pass between us, in a tone of the utmost seriousness, conversations of this nature.
