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.
You can leave the rest of the cabbage plant and harvest a later batch of cabbage sprouts, which will be 2 to 4 inches (5.1 to 10.2 cm) in diameter. Cabbage heads can be placed in the refrigerator for up to 2 weeks if covered loosely with a plastic bag.
