Use four burrs for each side of the hollow square chimney ([Fig. 130]), which is open at top and bottom.

To put the different parts of the house together lay the roof down flat and stick the edge of the back wall on top of the outer row of burrs which forms one of the long edges of the roof. Fasten one side wall on one short edge of the roof in the same way and press the edge of the back wall and the edge of the side wall together, making the corner firm and square. Next attach the second side wall, and lastly fit in the front wall.

Now lift the house carefully, place it right side up on the ground, and adjust the chimney to the roof. As you work keep the picture of the house in front of you so that you may see at a glance whether you are building it correctly or not. If you cannot find large burrs, let the sides and the roof of the house be two layers of burrs stuck firmly together. Make a path leading up to the door of very small shells, sand, or fresh earth.
