The boys immediately decided that a day 's search might not have provided them with a better spot , and in a short time were bustling actively about building their new camp . This consisted merely of throwing together a brush lean-to . The brush lean-to is the simplest sort of forest home . It is made by erecting two poles , six to seven feet in height , and about six to eight feet apart . In back of these , at a distance of some six feet , are placed two more poles about one-half the height of the first pair . Four poles are laid on the tops of these , secured by cutting a cleft in the tops , and laid so as to form the frame work for the roof of the lean-to . The next step in the building of such a habitation is to lay poles at an interval of a foot or a foot and a half along the roof part of the lean-to .
