The molt or change of the worm is easily recognized by a -willing of the head, whitening of the skin, transparency of the body, and a fixed FIG paper used in changing beds in the second and third ages. To change the beds, proceed as before, only leave undisturbed on the old beds the worms that are molting. When all the tardy worms have been taken up and placed on shelves, give them frequent sprinklings of finely cut up leaf to enable them to catch up with the worms already molting. Diminish the feeding a- the backward worms begin to molt, and cease feeding entirely a- soon a- a -ingle worm comes out of the molt. Then wait twenty-four hours SO that the worm- may be well over the change before giving a general meal. In this way the equality of development necessary for a methodical and successful rearing i- maintained. A fast oi twenty-four hour- will not hurt tin1 advanced worms, while the extra feeding given to the backward ones may enable them to become equal to the former. The beds of the worms on the old litter may be changed when the general meal i> Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Kelly, Henrietta Aiken, 1844-.
