"Why, I couldn't have any fun at all without you two; at least, it
would be very lonesome fun."

"I don't see how they ever built it," said Molly, who, by way of
finding out, was hanging out of a window as far as she could and
investigating the building.

"I know," said the wise Stella; "I read about one once; they nail
the beams and things to the trunks of the trees and then they nail
boards across, and then they build the house. But the one I read
about wasn't as nice as this."

"I don't think there could be one as nice as this," declared
Marjorie; "and we can fix it up a lot yet, you know. I shall bring
some things down from my room, some of my favorite books for the
book-shelves, and things like that."

"Do you suppose it will rain in, ever?" asked the practical
Stella.

"No, of course not," said Molly, who was still examining the
carpenter work. "See, these windows slide shut sideways, and then
if you shut the door tight the rain couldn't get in, unless the
roof leaks."

"Of course it doesn't!" declared Midget; "Uncle Steve wouldn't
build me a house with a leaky roof. Did you ever see such cunning
window curtains! Of course we don't need blinds, for the tree
keeps the sun out. It does seem so queer to look out of the window
and see only a tree."
