his friend Dr. Wavell at Barnstaple, found it at that
gentleman's table; and on his return he collected some seeds, and
planted a considerable spot of ground with it at Brompton in 1792; at
which time it was again introduced to Covent-Garden, but with so little
successs, that no person was found to purchase it, and consequently the
crop was useless.

This celebrated botanist, however, published a small tract on its uses
and culture, which met with a considerable sale, and introduced it again
to general cultivation.

The seeds should be sown in March, and the following year the plants are
fit for forming plantations, when they should be put out in rows about
three feet apart, and one foot in the row. The vegetable is blanched
either by placing over the crowns of the root an empty garden-pot, or by
earthing it up as is usually done with celery. It is easily forced, by
placing hot dung on the pots; and is brought forward in January, and
from thence till May.

It has been noticed of sea-kale, that, on eating it, it does not impart
to the urine that strong and unpleasant scent which asparagus and other
vegetables do.

471. SKIRRETS. Sium Sisarum.--The roots of this plant are very similar
to parsneps, both in flavour and quality; they are rather sweeter, and
not quite so agreeable to some palates. It is a biennial sown in March,
and used all the winter.

472. SORREL, COMMON. Rumex Acetosa.--Bryant says the Irish, who are
particularly fond of acids, eat the leaves with their milk and fish; and
the Laplanders use the juice of them as rennet to their milk. The
Greenlanders cure themselves of the scurvy, with the juice mixed with
that of the scurvy-grass. The seeds may be sown, or the roots planted,
in spring or autumn; it is not in general cultivation, but is to be
found abundantly wild in meadows, &c.

473. SORREL, ROUND-LEAVED, or FRENCH. Rumex scutatus.--The leaves of the
plant have more acidity in them than the common; and although not in
general use, it is one of the best salad-herbs in the early part of the
year: it is propagated in the same mode as the common sort.

474. SPINACH, Spinacia oleracea.---Two sorts of this vegetable are
cultivated. The Round-leaved, which is very quick in its growth, is sown
for summer use; and if the seeds are put into the ground every three
weeks, a constant succession is obtained while the weather is warm; but
frost will soon destroy it.

The Prickly Spinach is no
