which had the king’s name stamped on them, with other writing in a square bounded centre. The bricks were twelve inches long, twelve inches wide, and three inches thick and looked like [Fig. 372]. You must pretend that your pasteboard pillars between each opening are made of just such bricks and that there are many, many more brick pillars throughout the entire space beneath the floors.

Cut Light-Green Tissue Paper
into strips wide enough to extend a trifle over the edge of the platforms while reaching in across the top far enough to have the inner edge of the strip covered by the platform resting over it. The tissue paper should form a flat green band bordering the entire top ledge of the first three platforms.
Cover the entire top of the fourth and last platform with the green tissue paper.
Before you can
Plant the Shrubs and Trees
you must dig holes in the earth for their roots. Take each platform in turn and, with a coarse darning needle, puncture holes entirely through both green paper and pasteboard. Let the holes be in straight rows; make them on the projection or step of each platform, midway between the extreme edge and the walls of the next higher story. On the first, second and third platforms the holes should be an inch and a half apart. Pierce three holes through the top of the fourth platform, one at the back on the extreme left-hand corner and one on each side of that hole, but much nearer the centre.
