Geo. Then there is no difference between corn and grass, but the size?
Tut. None at all.
Har. But we eat corn; and grass is not good to eat.
Tut. It is only the seeds of corn that we eat: we leave the stalks and leaves for cows and horses. Now we might eat the seeds of grass, if they were big enough to be worth gathering; and some particular kinds are in fact eaten in certain countries.
Har. But are wheat and barley really grass?
Tut. Yes—they are a species of that great family of plants, which botanists call grasses; and I will take this opportunity of telling you something about them. Go, George, and pull us up a root of that rye-grass. Harry and I will sit down on this stile till you come to us?
Har. Here is grass enough all round us.
Tut. Well, then, pull up a few roots that you see in ear.
Geo. Here is my grass.
Har. And here is mine.
