The word hereof is actually not a legal term. Its meaning in court documents is no different from its ordinary dictionary definition -- Merriam-Webester defines hereof as meaning of this.. It's one of those words used by lawyers and nobody else.
The variety of cabbage commonly known as the Flat Dutch, shown in Fig. 6, of which there are many strains, is a moderately long-season variety. The head is very solid and flat; it measures about 12 inches across and 8 inches deep, and weighs from 8 to 12 pounds.
Early varieties are usually planted 12 inches apart in all directions. Early varieties produce 1 to 3 pound heads and later varieties produce 4 to 8 pound heads. Sow cabbage seed 1/4 to 1/2 inch deep. Keep the seeds moist and thin or transplant the seedlings to the desired spacing. The plants removed may be transplanted to another row or flat.
