"If these seed leaves are real leaves, uncle," asked Donald, "what feeds the baby morning glories?"
"There is plenty of food in the seed around the leaves," said Uncle Robert. "When the seed gets moist in the ground, it becomes so soft that the plant can use it. Have you ever noticed when you were eating corn the little hard bud that grows in each grain close to the cob?"
"Yes, uncle," answered Susie. "That is the sweetest part of the corn."
"That is the part," said Uncle Robert, "from which the new plant grows, and all the rest of the grain is the food stored up for it."
"I wish we had some corn," said Susie, "so we could see it."
"I'll go and get some," said Donald.
"Oh, do, Don," said Susie, "and while he's gone, Uncle Robert, I can plant the rest of my seeds. I have only a few left."
So Donald ran to the cornfield and Susie went to the garden. When he came back she had finished, and they joined Uncle Robert on the piazza.
"The corn grows out of the side of the seed," said Donald. "See what a big root it has for such a little plant!"
