"Why, Uncle Robert walked ten miles the other day," said Harry; "he could walk all around those little worlds. And if they are so little, I suppose he would weigh scarcely anything at all if he lived on one of them. I should think he would be almost like the giant with the seven-league boots. Don't you remember, Nellie, you were reading about him the other day. Poor little Jack the Giant Killer would not have much chance there, but perhaps he could fly if he weighed so little. And how would football be on these little worlds?" "You might give the ball such a kick that it would leave the planet altogether and circle around the sun as a planet on its own account." How Harry and Nellie laughed at the idea of a football circling around the sun as a planet! "And is this really true?" inquired Harry. "Why, this is better than any fairy story I ever heard. Now, tell me some more. Don't you think we might be able to fly on these tiny worlds?" "If you could get someone to make you a pair of wings up there, it would be quite easy to fly. Our bodies would only weigh a few pounds, so we ought to be able to flap a pair of wings strong enough to keep us flying. That is, if the air around these little worlds is as dense as ours." "Don't I wish I lived there, then," said Harry regretfully, "because it would not matter about my being lame. And I could put on my wings whenever I wanted to see you, Nellie, and fly across the park, and way, way up into the sky, and----" "Oh, don't! Harry," said Nellie, throwing her doll on the ground and catching hold of her cousin in dismay; "if you go you must take me with you too. And poor little dollie," she continued, suddenly remembering her precious charge, "and Cousin Mary and Uncle Robert and Aunt Agnes and everybody in the world. What would we do if you flew away from us?" "But I can't," said Harry, laughing at her dismay; "and it's just like a little girl to think I would go and leave her all alone. No, we'll all go some day, won't we?" he continued, turning to his sister Mary; "and we'll be with the angels--and have wings. You and Nellie and I--why, we will all fly, and I shall forget I ever was lame on planet earth then." "And will father have wings, too?" asked Nellie curiously. "He will want a very big pair, something like the big eagle's down at the aquarium." "Will he, you little rogue?" exclaimed the loud, good-natured voice of her father, as he appeared on the scene. "So this is where you are, and I have been looking for you all over the house and grounds." "I told nurse I would be back in a minute," she replied. "A minute!" said her father, laughing heartily; "why, you have been here nearly an hour. So you want your father to have wings, do you, you little rogue! Wait till I show you how you would fly if you had wings." The next moment he put her up on his shoulder, dollie and all, and ran with her across the meadow at full speed, while she laughed merrily and clapped her hands with delight.
