s. By the ordinary field
method from $150 to $300 is the usual range. Instead of throwing away
the leaves cut in September, it should be profitable to dry these leaves
and sell them in tins or jars for flavoring.

When it is desired to supply the demand for American seed, which is
preferred to European, the plants may be managed in any of the ways
already mentioned, either allowed to remain in the field or transplanted
to cold frames, or greenhouses. If left in the field, they should be
partially buried with litter or coarse manure. As the ground will not be
occupied more than a third of the second season, a crop of early beets,
forcing carrots, radishes, lettuce or some other quick-maturing crop may
be sown between the rows of parsley plants. Such crops will mature by
the time the parsley seed is harvested in late May or early June, and
the ground can then be plowed and fitted for some late crop such as
early maturing but late-sown sweet corn, celery, dwarf peas, late beets
or string beans.

When seed is desired, every imperfect or undesirable plant should be
rooted out and destroyed, so that none but the best can fertilize each
other. In early spring the litter must be either removed from the plants
and the ground between the rows given a cultivation to loosen the
surface, or it may be raked between the rows and allowed to remain until
after seed harvest. In this latter case, of course, no other crop can be
grown.

Like celery seed, parsley seed ripens very irregularly, some umbels
being ready to cut from one to three weeks earlier than others. This
quality of the plant may be bred out by keeping the earliest maturing
seed separate from the later maturing and choosing this for producing
subsequent seed crops. By such selection one to three weeks may be saved
in later seasons, a saving of time not to be ignored in gardening
operations.

In ordinary seed production the heads are cut when the bulk of the seed
is brown or at least dark colored. The stalks are cut carefully, to
avoid shattering the seed off. They are laid upon sheets of duck or
canvas and threshed very lightly, at once, to remove only the ripest
seed. Then the stalks are spread thinly on shutters or sheets in the sun
for two days and threshed again. At that time all seed ripe enough to
germinate will fall off. Both lots of seed must be spread thinly on the
sheets in an airy shed or loft and turned daily for 10 days or two weeks
to make sure they are t
