A PUMPING ENGINE
OTHER: When we visited the water-works what did you admire most of all the things you saw, Elmer?
Elmer: The great engines that kept pumping all the time and never stopped to rest. How strange it seemed to think that they pump enough water for all the people in this great city! The houses on the hillsides as well as those on low ground have all they need.
Mother: But you would hardly think the house we live in has the most wondrous little pumping engine you ever saw, would you? Day and night it pumps “the river of life,” as the blood has been called, to every part of the body. If it should once stop, we would die, and the body-house could never be used again.
Helen: Do you mean the heart, mother?
Mother: Yes. Can you tell me where your heart is?
Amy: I can. It is on my left side.
Mother: Not quite right, little girl. The lower point is felt on the left side, it is true; but most of the heart is higher up and nearer the center of your body. Who can tell how large it is?
