"I should think it would make your head ache to try to study about such things," said Felix, with a yawn; "it makes mine ache just to hear about it; it's all so queer and unlikely and mixed up. I think it's ever so much pleasanter to just take things as they are, without trying to make out what makes them so and so. I'm glad the grass is green, and the sky blue, and that there are other pretty colors in the world; but I don't care a cent what makes them so. Though I don't believe the color is just in the sun or our eyes."

"I like to know why things are so and so; in order to see how wise and beautiful the laws of Nature are, and what wisdom and beauty there must be in all the rest of the universe."

"What do I care about the rest of the universe? all I care about is the part of it which I am in."

"But when we see how wonderful this little part of it is, we can get a pleasant idea of what another world might be which we shall go into when we leave this: and that is ever so much pleasanter than having such a common idea about it as some folks have, as a place paved with gold, and built of stones; or to have no idea of it at all, or only to think of just being dead and buried. When we learn how every thing is made for some purpose, and nothing ever really dies, and then remember that our minds and feelings are the very highest part of all creation, and the most delicate and complicated, we feel very certain that there is some great future before us that we can't tell any thing about."

"If you can't tell any thing about it, what's the use of trying?"

"Why, it's enough for us to see that it must be something grand; that's all we want to know now: we've got plenty to enjoy and take up our minds here; all we want to know is, that we shall keep on having enough to busy us, and make us happy always; and Nature tries to tell us that in every way she can, or as much about it as she thinks it best for us to be told of. I am sure I am happier for knowing what little I have learned; and it makes me happy, too, to keep on learning curious things about Nature."

"I'd rather ride 'round on a bicycle, and see what's going on, any time, than study about such things," replied Felix, with another and longer yawn. "I know I feel well enough to ride home now. I'm going to get my bicycle."

Felix immediately rose, and walked around the house to the place where Johnny had placed the bicycles. But Johnny went into the office, and told the doctor Felix was determined to go, and asked him if he would try his pulse. The doctor, who had been sitting near a window of his office, not far from where the boys were conversing, had heard the whole of their conversation. But as the blinds were closed, the boys had not noticed this, and were rather surprised when, after feeling Felix's pulse, and saying it was safe for him to go, he remarked,—

"Well, my boy, you have had two lessons from Nature this morning: she taught you herself that you will get punished if you trifle with her laws,—viz., in this case, if you try to get along without using the eyes she has given you,—and she has taught you, second or third hand, through Johnny, something of the way in which she produces her beautiful and useful effects. So, although this is vacation time, you see a great many things can be learned outside of a schoolroom. Life is a great school, and you have just begun your course in it. Make the most of your advantages; for some folks go through life without learning much of any thing, just as some boys go through school and college, yet come out ignoramuses at last."

The doctor then told the boys he should like to have them stop any time they came that road, and that, if they would come in apple-time, they might take their choice of fruit from the trees in the orchard.
