BOX CUT DOWN TO HOLD GABLE ROOF] =Diagram Three.= Gable roof. This is a piece of cardboard cut oblong and folded through its center, lengthwise, to make a slanting roof. A deep box may be cut down to hold this roof and make a gabled building. Cut where heavy black lines indicate. _C._ Roof cut from a piece of plain cardboard or corrugated cardboard. _CC._ Box cut down to make the low sides and high-pointed gable ends of a small building. ------------------------------------------------------------------------ [Illustration: ROUND-POINTED ROOF, TENT ROOF, INDIAN WIGWAM, AND CARDBOARD TENTS FOR CAMP] =Diagram Three.= Roofs. _D._ Round-pointed roof cut from cardboard. Lap edges _x_ to _x_. This makes a tent also. The Indian Wigwam is made this way. _E._ This is a wide box cover folded through its center, rim cut up to the top on each long side.

TUNNEL] =Diagram Four.= By cutting the ends or sides of boxes, tunnels or bridges may be made. Cut where the heavy black line indicates. _A._ The bridge is made by cutting a semicircle from the long sides of an inverted box. The box cover, turned upward, forms the bridge railing. At each end, cut the corners. A cardboard strip is pasted to each end rim to complete the bridge roadway. _B._ The tunnel is made by cutting a circular opening in the two ends of a deep box which has been inverted.
