Directions for collecting and preserving insects . ll furnish room for the annual breeding ofa great number of species, as several having different habits and ap-pearance, and which there is no danger of confounding, may be simul-taneously fed in the same cage. I number each of the three parts ofeach cage to prevent misplacement and to facilitate reference, andaside from the notes made in the notebook, it will aid the memoryand expedite matters to keep a short open record of the species contained in each cage, by means of slips of paper pasted on the glassdoor. As fast as the different specimens complete their transforma-tions and are taken from the cage the notes may be altered or erased,or the slips wetted and removed entirely. To prevent possible con-founding of the different species which enter the ground, it is well,from time to time, to sift the earth, separate the pupa? and place themin what I call l imago cages, used for this purpose alone and not forfeeding. Here they may be arranged with references to their PIG. 124.—Improved base for breeding-cage (original). A continued supply of fresh food must be given to those insectswhich are feeding, and a bit of moist sponge thrust into the-mouth ofthe bottle will prevent drowning, and furnish moisture to such asneed it. By means of a broad paste brush and spoon the trass maybe daily removed from the earth, which should be kept in a nt andmoist condition—neither too wet nor too dry. In the winter, wheninsect life is dormant, the earth maybe covered with a layer of deanmoss, and the cages put away in the cellar, where they will need onlyoccasional inspection, but where the moss must nevertheless be keptdamp. Cages made after the same plan, but with the sides of wiregau/e instead ol glass, may be used Cor insects which do not well bearconfinement indoors, the cages to be ulaeed on a platform on the northside of a house, where they will receive only the early morning and lateevening sun/ [115] C
