"I did not water any of the cocoons," I answered. "I have done no sprinkling today. If they are wet, it has come from the inside."

Molly-Cotton dropped her trowel. "One of them was damp on the top before lunch," she cried. "I just now thought of it. The moths are coming!" She started on a run and I followed, but stopped to wash my hands, so she reached them first, and her shout told the news.

"Hurry!" she cried. "Hurry! One is out, and another is just struggling through!" Quickly as I could I stood beside her. One Polyphemus female, a giant indeed, was clinging to a twig with her feet, and from her shoulders depended her wings, wet, and wrinkled as they had been cramped in the pupa case. Even then she had expanded in body until it seemed impossible that she had emerged from the opening of the vacant cocoon. The second one had its front feet and head out, and was struggling frantically to free its shoulders. A fresh wet spot on the top of another cocoon, where the moth had ejected the acid with which it is provided to soften the spinning, was heaving with the pushing head of the third.

Molly-Cotton was in sympathy with the imprisoned moths.

"Why don't you get something sharp, and split the cocoons so they can get out?" she demanded. "Just look at them struggle! They will kill themselves!"

Then I explained to her that if we wanted big, perfect moths we must not touch them. That the evolution of species was complete to the minutest detail. The providence that supplied the acid, required that the moths make the fight necessary to emerge alone, in order to strengthen them so they would be able to walk and cling with their feet, while the wings drooped and dried properly. That if I cut a case, and took out a moth with no effort on its part, it would be too weak to walk, or bear its weight, and so would fall to the floor. Then because of not being in the right position, the wings would harden half spread, or have broken membranes and never develop fully. So instead of doing a kindness I really would work ruination.

"Oh, I see!" cried the wondering girl, and her eyes were large enough to have seen anything, while her brain was racing. If you want to awaken a child and teach it to think, give object lessons such as these, in natural history and study with it, so that every miraculous point is grasped when reached. We left the emerging moths long enough to set up a camera outside, and focus on old tree. Then we hurried back, almost praying that the second moth would be a male, and dry soon enough that the two could be pictured together, before the first one would be strong enough to fly.

The following three hours were spent with them, and every minute enjoyed to the fullest. The first to emerge was dry, and pumping her wings to strengthen them for flight; the second was in condition to pose, but a disappointment, for it was another female. The third was out, and by its smaller size, brighter markings and broad antennae we knew it was a male. His 'antlers' were much wider than those of the first two, and where their markings were pink, his were so vivid as to be almost red, and he was very furry. He had, in fact, almost twice as much long hair as the others, so he undoubtedly was a male, but he was not sufficiently advanced to pose with the females, and I was in doubt as to the wisest course to pursue.

"Hurry him up!" suggested Molly-Cotton. "Tie a string across the window and hang him in the sunshine. I'll bring a fan, and stir the air gently."

This plan seemed feasible, and when the twine was ready, I lifted his twig to place it in the new location. The instant I touched his resting-place and lifted its weight from the twine both females began ejecting a creamy liquid. They ruined the frescoing behind them, as my first Cecropia soiled the lace curtain when I was smaller than Molly-Cotton at that time. We tacked a paper against the wall to prevent further damage. A point to remember in moth culture, is to be ready for this occurrence before they emerge, if you do not want stained frescoing, floors, and hangings.
