Helen: There is a scar left.
Mother: This shows that the outer skin and the coloring matter will come back as they were before if they are hurt; but when the true skin is injured, the blood makes a kind of patch, which we call a scar. Another curious thing about the true skin is that it has tiny muscles, and when the body is cold, they draw up and make little hillocks, which we call “goose-flesh.”
But the skin is very useful, besides being a covering for the body. When we were getting dinner to-day, what did we do with the potato parings and other things we did not wish to keep?
Percy: We put them in the garbage box.
Mother: Why did we do that?
Amy: Because they were not fit for food.
Mother: And what do we call that which we do not wish to keep, and so throw away?
Helen: We call it waste.
Mother: What do we do with waste matter? Do we let it stay in the house?
Elmer: No; we throw it away.
