LESSON V
This is another symbolic cipher design picturing “Humpty-Dumpty.” The blue squares represent the a form, the red squares the b form. The cipher message is “sat on a wall.” The blank squares can be filled by colored crayons or blocks, and the children can thus practice the building of the message by referring to the code in Lesson I.
LESSON VI
Another symbolic cipher design in which the hens represent the b form, the chicks the a form. The cipher word is “egg,” reading from left to right.
This sort of symbolic cipher designing is susceptible of endless variation, and gives a hint of the possibility of drawing cipher pictures.
