stay underground and do their feeding from there."

"A sort of cold storage arrangement," smiled Ethel Brown.

"After these peas are a little taller you'd find if you pulled them up
that the supply of food had all been used up. There will be nothing down
there but a husk."

"What happens when this bean plant uses up all its food?"

"There's nothing left but a sort of skin that drops off. You can see how
it works with the bean because that is done above the ground."

"Won't it hurt those plants to pull them up this way?"

"It will set them back, but I planted a good many so as to be able to
pull them up at different ages and see how they looked."

"You pulled that out so gently I don't believe it will be hurt much."

"Probably it will take a day or two for it to catch up with its
neighbors. It will have to settle its roots again, you see."

"What are you doing this planting for?" asked Dorothy.

"For the class at school. We get all the different kinds of seeds we
can--the ones that are large enough to examine easily with only a
magnifying glass like this one. Some we cut open and examine carefully
inside to see how the new leaves are to be fed, and then we plant others
and watch them grow."
