"The caterpillars of some moths go into the earth before they change into the pupæ state. I do not know why: I suppose they think it safer." "Where did you learn all this?" said Dick, his eyes lighting up with a new life and interest at this first glimpse of what was to him a new and strange world. "From my brother Frank and Jimmy Brett. They are making collections, and we are helping them as much as we can. My brother is Frank Merivale, and I am Mary Merivale." "And my name is Carleton; but please tell me more about these things. Will they turn into white butterflies?" "They won't turn into butterflies at all, but into moths, great ugly things with thick bodies; only Frank and Jimmy like them." [Illustration: METAMORPHOSES OF BUTTERFLY.] "I should like to find some if you will show me how to dig for them. I suppose if I keep them they will turn into moths some time." [Illustration: THE PARK IN SUMMER.] "Yes; put them into a flower-pot full of mould and keep it rather damp, and put something over so that the moths sha'n't fly away, and in the spring they will come out; but it is prettiest to see butterflies come out. They split open the chrysalis at the back of its neck and creep out, but their wings are all shrivelled up to nothing, and they climb up the side of the box, and then their wings spread out, and get so large and beautiful! I could find you plenty of the chrysalides of the white butterflies by your greenhouses, but if you want moths, take this trowel and dig around the other side of this tree about three inches from it and three inches deep. They do not breed on all trees; we have tried five to-day and found nothing, but at this one we have got twelve." More amused and interested than he had ever been before, Dick knelt down and began to dig. Very soon he found a large chrysalis, and, encouraged by this success, he dug more vigorously, and very soon he had found five, while the girls had increased their spoils to sixteen. "Now, Miss Merivale, will you come to the greenhouses and show me how to get some butterfly chrysalides? I shall be very glad if you will, and I should like to introduce you to my father, and I will ask him to ask your brother here, then he could tell me more about these things." [Illustration: WHITE HAWTHORN BUTTERFLY.] Mary hesitated, but Florrie said, "Oh, do go, Mary;" so she consented, and they walked up through the gardens, and Mary showed Dick where to look for the chrysalides of the common white butterfly, which are to be found through the winter attached by a silken thread to the sheltered sides of walls, and under the coping of greenhouses and buildings near the gardens where the caterpillars have fed on the lettuces and cabbages. Sir Richard Carleton was in one of the conservatories, and seeing him, Dick cried out-- "Father, these red things will turn into moths, and these greenish-white ones into butterflies." "Yes, Dick, I know they will." "But you never told me so before, father."
