"Let us look at some plant in the garden. We shall find that one part of it is not at all like another part. Teacher broke a stone with the hammer, and we saw that one piece of the stone is just the same as the other. All minerals are like the stone in this. They have no distinct parts. But each part of the plant is unlike any other part,and has its own work to do. "Look at this plant, and tellus, Norah, what parts of it you can see.""I can see the part that comes out of the ground, and rises up into the air." said Norah.
"Yes," said Fred, "that is the stem stalk.""Then," said Norah, "I can see the green leaves of the stalk.""Quite right, but is there no other part?""Oh, I know," said Norah, "you mean the root, which we can"t see, because it is in the ground.""Don"t forget then," said Fred, "that e ver y plant must have a root, a stem, and leaves. The root feeds the plant.""Now come to the gate, where the sweet-peas are growing over the church," said Fred again. "Can you see anything here that we did not see in the others?""Oh yes," said Norah,
"there are pretty flowers on these."
