At first it was only meant to be a kind of shelter on poles, but, as they had so much time upon their hands, they agreed to build real walls, and leave space for a door and a window.

In little more than a week they had the framework all up, and the roof all made.

It was thatched first with broad leaves, and then with grass.

And, mind you a short ladder had to be made first to permit them to do the thatching.

When this was finished, all the sides were filled in with willow branches, except door and window.
