e-inch pots and placed in a cool house will often tide over a
difficult period. In gathering, care should be taken to pick separately
the young leaves that are nearly full grown, and to take only one or two
from each plant. It costs no more time to fill a basket by taking a leaf
or two here and there from a whole row than to strip two or three
plants, and the difference in the end will be considerable as regards
the total produce and quality of the crop.

==Pennyroyal== (=Mentha Pulegium=) is a native perennial which must be
propagated by divisions, and this can be done either in spring or
autumn. The rows may be twelve or fifteen inches apart, but in the rows
the plants do well at a distance of eight inches. The taste for
Pennyroyal is by no means universal, but some persons like the tender
tops in culinary preparations. The belief in its supposed medicinal
virtues is slowly dying.

==Purslane== (=Portulaca oleracea=).--This annual plant thrives best in a
sunny position. Seed should be sown from mid-April onwards to insure a
succession of young leaves and shoots which may be cooked as a vegetable
or eaten raw as a salad. Space the rows nine inches apart and thin the
plants to a distance of six inches.

==Rampion== (=Campanula Rapunculus=).--Both leaves and roots are used in
winter salads; the roots are also boiled. If the seed be sown earlier
than the end of May the plants are liable to bolt. Choose a shady
situation where the soil is rich and light, and do not stint water. The
rows need not exceed six inches apart, and four inches in the rows will
be a sufficient space between plants.

==Rosemary== (=Rosmarinus officinalis=).--A hardy evergreen shrub easily
grown from seed, the leaves of which are used for making Rosemary tea
for relieving headache. An essential oil is also obtained by
distillation. A dry, warm, sunny border suits the plant. Sow in April
and May.

==Rue== (=Ruta graveolens=).--A hardy evergreen shrub, chiefly cultivated
for its medicinal qualities. The leaves are acrid, and emit a pungent
odour when handled. The plant is shrubby, and as it attains a height of
two or three feet it occupies a considerable space. Sow in April.

==Sage== (=Salvia officinalis=).--Although Sage can be raised from seed
with a minimum of trouble, yet this is one of the few instances where it
is an advantage to propagate plants from a good stock. The difference
will be obvious to any gardener who will grow seedlings by t
