Page 10. I like the long rods, too! I must put the rods near each other according to their length. I must be careful to place the blue sections near the blue ones and the red ones near the red. Thus, I build some pretty stairs with red and blue steps.
Page 11. But to get a real stair case I use the brown prisms. These prisms are of different size, and I get some fine stairs with ten steps.
Page 12. I have also some solid insets of wood into which I fit little cylinders of different dimensions. They differ in length and breadth. The game is to put these cylinders in their places after looking at them and touching them carefully.
Page 13. We often make mistakes in working with the insets. When we put a cylinder where it doesn't belong, we find that at the end of the game we have one cylinder left over and it won't fit in anywhere. Then the exercise becomes very exciting. We look at the inset carefully; we find the mistake and begin all over again. The most skilful pupils work the insets with their eyes closed.
Page 14. These colors are called: red, black, green, yellow, blue, brown, pink and violet.
Page 15. I amuse myself by picking out and pulling together pieces of the same color from the collection spread out over my table. I get thus a long strip of different colors.
Page 16. We learn to arrange sixty-four different colors by graduations. We get eight beautiful blends of colors, each formed by eight tints of different tones. When we become skilful we can make a pretty rug with blending strips.
Page 17. We also have two little chests full of pieces of cloth. The cloths are of all kinds from the roughest and hardest to the smoothest and softest: canvas, cotton, linen, wool, flannel, velvet, etc. If we keep our hands clean, we can learn to recognize all sorts of things with the tips of our fingers!
Page 18. A child is blindfolded. He mixes the pieces of cloth with his little hands. He feels about among the pieces of cloth. At last he smiles and holds up his hands with two pieces of cloth, both alike. Though he could not see, the child has found out, just by using his fingers, that the two pieces were of the same cloth.
