“Authors are persons who write books, and if authors did not write books, printers could not print them; and you see that an author must write, and a printer must print what he writes, before we can have our books to learn from. “If we are sick, we send for a doctor, because he can tell what ails us. The doctor’s business is to learn a great deal about the human body, which we have no opportunity to learn. He knows where our brains lie; and where our heart is; and where the lungs are placed through which we breathe; and he can tell how our bones are knit together, and what is the office of every nerve and fibre and muscle in our bodies. His knowledge teaches him the laws by which we move our tongues and our heads and our limbs; and if we are sick, he knows that something within us is out of order, and that disease is the consequence, and he can often tell what the disease is. Thus you see we are dependent upon the doctor, when we most need help, that is, when we are sick and cannot help ourselves. And if it pleases our heavenly Father that we should be restored to health, the doctor’s knowledge of our bodies enables him to cure us.” _Charles._ “I know now, what my mother meant, when she said a little verse about God, after brother Harry got well of the measles.” _Mary._ “Will you repeat it Charles?” “God blessed the doctor’s skill; My heart is full of joy, That it has been Our Father’s will To give me back my boy.” Mary’s scholars were all listening to her talk with Charles Linn: and she told them that our heavenly Father designed all classes of men to help one another, and he requires them to love one another too. “Are we to love everybody, Mary?” asked Susan Field. “Yes,” said Mary. “If we love God, we cannot help loving every one whom he has made: and if we do not love God, we cannot love our fellow beings as we ought to love them.” “But we are not to love little dirty ragged boys and girls; are we, Mary?” said Susan. _Mary._ “Yes! and we are to try to do them good: but we cannot love them and do them good unless we love our heavenly Father. If we ask our heavenly Father for his help, he will teach us by his good Spirit in our hearts how we may show our love to him. And if we love him, we shall feel as if we wanted to do something even for poor little ragged boys and girls; and when we help them, or instruct them, we shall find out in what ways the rich and the poor are dependent upon one another. “And now, we must not talk any more at present: I intend to give you a long recess this morning. I promised you, you know, to go out with you to gather flowers and plants for our botanical exercise.”
