Mistletoe.—Raise the bark of an apple, pear, or oak tree on the underneath part of a branch and insert some well-ripened berries, then tie the bark down neatly with raffia or woollen yarn. If the berries were inserted on the top of the branch the operation would result in failure, as the birds would devour them.
Mitella Diphylla.—A hardy perennial which bears slender racemes of white flowers in April. It makes a pretty rock plant, delights in a peat soil, and is increased by division of the root. Height, 6 in.
Moles.—These pests may be destroyed by placing in their runs worms that have been kept for some time in mould to which carbonate of barytes has been added.
Monardia Didyma (Oswego Mint, or Horse Balm).—See "Bergamot."

Montbretia.—Very graceful and showy plants. The flowers, which are like small Gladioli, are produced on long branched spikes and are excellent for cutting. Plant 3 in. deep and 2 in. apart in sandy loam and leaf-mould. The corms should never be kept long out of the ground, as they shrivel, and weak growth and few flowers are the result. Though they are hardy it is well to give them a covering of litter in winter. They may also be grown in pots. Height, 2-1/2 ft.
