Fig. 9.––The Tower.
The series of objects to follow after the cylinders 34 consists of three sets of geometrical solid forms:
(1) Ten wooden cubes colored pink. The sides of the cubes diminish from ten centimeters to one centimeter. (Fig. 9.)
With these cubes the child builds a tower, first laying on the ground (upon a carpet) the largest cube, and then placing on the top of it all the others in their order of size to the very smallest. (Fig. 10.) As soon as he has built the tower, the child, with a blow of his hand, knocks it down, so that the cubes are scattered on the carpet, and then he builds it up again.
