And so it is with all the rest of our food. We live on either plants or animals. If there were no plants, there would be no animals, for animals cannot live without plants.

It is something like the house that Jack built, isn’t it?

“We are the children that drink the milk, that comes from the cows, that eat the grass, that grows from the seeds in the meadow.”

“If there were no seeds, there would be no grass to feed the cows that give us our milk for breakfast.”

And so it is everywhere. Plants give us a kind of food that we must have, and that only they can give. They could get on well enough without animals. Indeed, for a long time they did so, many hundreds of years ago. But animals cannot live without plants.

I think you will now remember why seeds are of such great importance.

HOW THE APPLE SHIELDS ITS YOUNG

Some time ago you noticed that apple seeds were packed away within the apple as neatly as though they were precious jewels in their case.
