[114] "A dozen sncli cages will furnisli room for the animal breeding of a 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 of each cage to prevent misplacement and to facilitate reference, and aside from the notes made in the notebook, it will aid the memory and expedite matters to keep a short open record of the species con- tained in each cage, by means of slips of paper pasted on the glass door. As fast as the different specimens comjjlete their transforma- tions and are taken fi-om 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 pupte and place them in what I call 'imago cages,' used for this purpose alone and not for feeding. Here they may be arranged with references to their exact Pig. 124.—Improved base for breeding-cage (original). "A continued supply of fresh food must be given to those insects which are feeding, and a bit of moist sponge thrust into the mouth of the bottle will prevent drowning, and furnish moisture to such as need it. By means of a broad paste brush and spoon the frass may be daily removed fi'om the earth, which should be kept in a fit and moist condition—neither too wet nor too dry. In the winter, when insect life is dormant, the earth may be covered with a layer of clean moss, and the cages put away in the cellar, where they will need only occasional inspection, but where the moss must nevertheless be kept damp. Cages made after the same plan, but with the sides of wire gauze instead of glass, may be used for insects which do not well bear confinement indoors, the cages to be place
