If the unit forms are in gradation of size, the space left over by diminishing unit forms can be used for the accommodation of a set of unit forms in reverse gradation. [For example] the original unit forms can occupy the central portion of the structural subdivisions, whereas a new set of unit forms can occupy intersections of the structural lines.
In a gradation structure, alternate gradation can be obtained if the A rows gradually diminish while the B rows gradually expand simultaneously in the same direction . . . . the combined width of every pair of A and B rows should always remain constant [or in very slow gradation] . . . .
