Mushrooms.—Take partially dry horse manure and lay it in a heap to ferment. Turn and mix it well every few days, and when well and equally fermented, which will be from ten to fourteen days, make it into a bed 4 ft. wide and 2 ft. deep, mixing it well together and beating or treading it firmly. When the temperature of the bed falls to 75 degrees, or a little under, the spawn may be inserted in pieces about the size of a walnut, 2 in. deep and 6 in. apart. Now give a covering of loamy soil, 2 in. deep, and beat it down evenly and firmly. Finish off with a covering of clean straw or hay about 1 ft. thick. Water when necessary with lukewarm water; but very little should be given till the Mushrooms begin to come up, then a plentiful supply may be given. They may be grown in any warm cellar or shed, and usually appear in from four to six weeks after planting.
Musk (Mimulus Moschatus).—A well-known sweet-scented, half-hardy perennial, well adapted for pot culture. A moist, shady position is most congenial to it when placed in the border. Seed sown in autumn make fine, early-flowering greenhouse plants. For summer blooming the seed is sown early in spring, under a frame or hand-glass, at a temperature of from 55 to 60 degrees. It is readily propagated by division. Height, 6 in.
Mustard and Cress.—For sowing in the open choose a shady border, make the surface fine and firm, and water it well before putting down the seed. Let the seed be sown thickly at intervals of seven or fourteen days from March to September. As the Cress does not germinate so quickly as the Mustard, the former should be sown four days before the latter. The seed must not be covered, but simply pressed into the surface of the soil. Keep the ground moist, and cut the crop when the second leaf appears. For winter use it is best sown in boxes and grown in a frame, the seed being covered with flannel kept constantly moist. This may be removed as soon as the seed germinates. Gardeners mostly prefer to grow it through coarse flannel, to avoid the possibility of grit being sent to table. The curled leaf Cress is the best, and the new Chinese Mustard is larger in leaf than the old variety, and is very pungent in flavour.
Myosotis (Forget-me-not).—The perennial varieties of these beautiful plants grow best in moist places, such as the edges of ponds or ditches; but they also do well in pots among Alpine plants. Most of them may be increased by root division, and all of them by seed. The annuals like a dry, sandy soil, and are grown from seed sown in March. They flower in June or July. Height, 6 in.
Myrica Gala (Candleberry Myrtle).—This hardy deciduous shrub is very ornamental, and its foliage is scented like the myrtle. It will grow in light, rich soil, but thrives best in peat, and may be increased by seeds or layers. May is its flowering time. Height, 4 ft. M. Cerifera is treated in precisely the same manner. Height, 6 ft.
