he grass is well established. To form a thick bottom
quickly on new Lawns sow 60 lbs., or 3 bushels, to the acre; for
improving old ones, 20 lbs. per acre. Frequent cutting and rolling is
essential to success. If the grass is inclined to grow rank and coarse
it will be much improved by a good dressing of sand over it; if it has
an inclination to scald and burn up, sprinkle it with guano or soot
just before a shower of rain. An accumulation of moss upon a lawn can
only be cured by under-draining.

Lawns, Shrubs for.--_See_ "Shrubs for Lawns."

Layering.--_See under_ "Carnations."

Ledum (_Labrador Tea_).--Low-growing American evergreen shrubs,
thriving best in sandy peat, and may be increased by layers.

Leek.--Sow early in March, and prick out the plants in rich soil, in a
sheltered position, to strengthen. As soon as they are large enough,
plant them out in very rich, light ground in drills 6 in. between each
plant and the rows 18 in. apart. For large exhibition Leeks sow in
boxes in February, under glass. Plant out in June in trenches 15 in.
wide and 18 in. deep, with plenty of old manure at the bottom of the
trench and 6 in. of good light mould on the top of it. Gradually earth
up as the stems grow. Water liberally in dry weather, and give a
little weak liquid manure occasionally.

Leontopodium.--Hardy perennials, succeeding best in peat soil. They
are most suitable for rock-work, and may be increased by seed or
division of the roots. Bloom is produced in June. Height, 6 in.

Leopard's Bane.--_See_ "Doronicum."

Leptosiphon.--Charming hardy annuals which make nice pot-plants. The
seed should be sown in rich, light soil--peat for preference. If this
is done in autumn they will flower in April and May; if sown in
spring they will bloom in autumn. They are very attractive in beds or
ribbons, and also on rock-work. Height, 3 in. to 1 ft.

Leptospermum.--Neat greenhouse evergreen shrubs, most at home in equal
portions of loam, peat, and sand. Cuttings may be struck in sand under
glass. They flower in June. Height, 4 ft. to 5 ft.

Leschenaultia.--Elegant greenhouse shrubs, delighting in a mixture of
turfy loam, peat, and sand. They are evergreen, flower in June, and
are propagated by cuttings of the young wood under glass. Height, 1
ft.

Lettuce.--Sow early in February on a slight hotbed, and prick out into
a well-manured and warm border, having the soil broken down fine on
the surface. For early summer supplie
