"The most wonderful," said her father.

"The most wonderful," repeated Maggie. "It was indeed, papa, and you need not think I was mistaken, for I am quite, quite sure I saw it."

"And what was this most wonderful thing you are so very sure you saw, Maggie?"

"It was the sun, papa, coming right up out of the water, and it was not put out a bit. It came up, up, away off there, where the sky touches the water. Mamma said we could not see the end of the ocean, but I see it quite well. Do not you see it, too, papa?"

"I see what appears to be the end of the ocean, but these great waters stretch away for many hundred miles farther. If you were to get on a ship and sail away as far as you can see from here, you would still see just as much water before you, and the sea and the sky would still appear to touch each other: and however far you went it would always be so, until you came where the land bounds the ocean on the other side. The place where the sky and water seem to meet, is called the horizon; and it is because they do seem to touch, that the sun appeared to you to come out of the water. It is rather a difficult thing for such little girls as you and Bessie to understand, but I will try to make it plain to you. You know that the earth is round, like a ball, do you not, Maggie?"

"Yes, papa."

"And I suppose that you think that the sun is moving when it seems to come up in the morning, and goes on and on, till it is quite over our heads, and then goes down on the other side of the sky until we can see it no more, do you not?"

"Yes, papa."

"But it is really the earth on which we live, and not the sun, which is moving. Once in twenty-four hours, which makes one day and one night, the earth turns entirely round, so that a part of the time one side is turned to the sun, and a part of the time the other side. See if you can find me a small, round stone, Maggie."

Maggie looked around till she found such a stone as her father wanted, and brought it to him. "Now," he said, "this stone shall be our earth, and this scratch the place where we live. We will take off Bessie's hat and have that for the sun. Now I will hold the mark which stands for our home, directly in front of our make-believe sun. If a bright light were coming from the sun and shining on our mark here, it would be the middle of the day or noon, while it would be dark on the other side. Then, as our earth moved slowly around in this way, and we turned from the sun it would become afternoon; and as we turned farther yet till we were quite away from the sun, it would be night. But we do not stay there in the dark, for we still go moving slowly round until our side of the earth comes towards the light again, and the darkness begins to pass away. The nearer we come to the sun the lighter it grows, until, if some little girl who lives on our scratch is up early enough and looks out at the horizon, or place where the earth and sky seem to meet, she sees the sun showing himself little by little; and it looks to her as if he were coming up out of the sea, while all the time the sun is standing still, and the earth on which we live is moving round so as to bring her once more opposite to him."
