Then, too, they are trying to flower.

“But they don’t all have flowers,” objects one voice.

You are right. They do not all have flowers; but you would be surprised to know how many of them do. In fact, all of them except the ferns and mosses, and a few others, some of which you would hardly recognize as plants,—all of them, with these exceptions, flower at some time in their lives.

All the trees have flowers, and all the grasses (Figs. [9], [10]); and all those plants which get so dusty along the roadside, and which you call “weeds,”—each one of these has its own flower. This may be so small and dull-looking that you have never noticed it; and unless you look sharply, perhaps you never will. But all the same, it is a flower.

But there is one especial thing which is really the object of the plant’s life. Now, who can tell me this: what is this object of a plant’s life?

Do you know just what I mean by this question? I doubt it; but I will try to make it clear to you.

Fig. 9

If I see a boy stop his play, get his hat, and start down the street, I know that he has what we call “an object in view.” There is some reason for what he is doing. And if I say to him, “What is the object of your walk?” I mean, “For what are you going down the street?” And if he answers, “I am going to get a pound of tea for my mother,” I know that a pound of tea is the object of his walk.

So when I ask what is the object of a plant’s life, I mean why does a plant send out roots in search of food, and a stem to carry this food upward, and leaves to drink in air and sunshine? What is the object of all this?
