=Fish do not pair off.=--We found in the study of the plants that the seed were fertilized while in the pod or ovary. In the fish we found that the eggs are fertilized outside of the mother’s body. In nearly all the animals above the fish the eggs or ova are fertilized while in the mother’s body. There is no love between the male and the female fish. They do not pair off and live in families. Among all the spiders, lizards, serpents, many of the insects, crawfish, frogs and toads there is a tendency, at certain seasons, for the male to choose a female with a view to a home and family. But among all the animals we have named, many of the male and female animals part or leave each other as soon as the eggs are fertilized, and all the others leave each other as soon as the eggs are hatched. The love of the male for the female lasts but for a little time; while there is no love for their young after they are hatched. Before the young are hatched some of their parents show interest in their eggs and make some provisions for their young when hatched. But this is all done before the young are hatched. The young all grow up as little orphans. CHAPTER X THE THIRD STORY--BABY BIRDS When our little girls were seven and nine this talk was given. The previous stories were reviewed bringing out the resemblances and differences. They were permitted to ask questions. In this talk they were very alert to see and apply all the lessons learned from previous stories. =The beginning of love.=--In this review of the story of life, among the plants and fish, we found no love or personal feeling between the male and female. Among the insects and reptiles we found that the males and females choose each other, when led by instinct to bring their young into the world. From the fish to the birds we find the simplest form of love and interest on the part of the parents in their young. This is shown by the care the parents take in the protection and care of the eggs and the food prepared for the young before they are hatched. The male crawfish picks up the fertilized eggs with his feelers, that are arranged in a double row underneath his tail, and, by means of these feelers, he carries the eggs close to his body until they are nearly ready to hatch. The frogs and toads show great tenderness for their eggs. A great many books have been written about all these animals and when you are older you will be greatly interested in learning more of the detail of reproduction among these curious animals. Among all the animals we have studied the male and female separate as soon as the eggs are fertilized and laid, in other cases as soon as the eggs begin to hatch. The parent animals show no interest in their young after they are hatched and their children never know their parents or love them.
