ve too much wet. Do not allow them to ramble
after the fruit has begun to swell, nor allow the plants to bear more
than two, or at most three, melons each. They require a strong,
fibry, loamy soil, with a little rotten manure worked in. The Hero of
Lockinge is a grand white-fleshed variety, and Blenheim Orange is a
handsome scarlet-fleshed sort.

Menispermum Canadense (_Moon seed_).--A pretty slender-branched,
hardy, climbing, deciduous shrub, with yellow flowers in June,
followed with black berries. It grows in any soil, and can be
propagated by seed, by division of roots, or by planting cuttings in
spring in a sheltered spot. Height, 10 ft.

Mentha Rotundifloria Variegata (_Variegated Mint_).--A hardy
perennial, which may be grown in any soil, and is easily increased by
dividing the roots. It flowers in July. Height, 2 ft.

Menyanthes.--Treat as other hardy aquatics.

Menziesia (_Irish Heath_).--This evergreen thrives best in fibrous
peat to which a fair quantity of silver sand has been added. While
excessive moisture is injurious, the plant must not be kept too dry;
the best condition for it is to be constantly damp. Slips torn off
close to the stem will root in sand under glass, placed in gentle
heat. Height, 2 ft.

Mertensia.--These hardy perennials flower from March to July. They
will grow in any garden soil, but do best in peat, and are propagated
by division. They make fine border plants. Mertensia Maritima and
M. Parviflora, however, are best grown in pots, in very sandy soil,
perfection being afforded them during the winter. Height, 11/2 ft. to 2
ft.

Mesembryanthemums (_Ice Plants_).--These half-hardy, annual succulents
have a bright green foliage covered with ice-like globules. They must
be raised in a greenhouse or on a hotbed, sowing the seed in April on
sandy soil. Prick the young plants out in May. If grown in pots they
thrive best in a light, sandy loam. In the border they should occupy a
hot and dry situation. Keep the plants well watered until established,
afterwards give a little liquid manure. May be increased by cuttings
taken in autumn. Cuttings of the more succulent kinds should be
allowed to dry a little after planting before giving them water. A
dry pit or frame is sufficient protection in the winter; they merely
require to be kept from frost. Flower in July. Height, 1 ft.

Mespilus.--_For treatment, see_ "Medlars."

Meum Athamanticum.--A hardy perennial with graceful, feathery green
