Ants in Gardens.--Contrary to general belief, ants do more good
than harm to a garden; but as they are unsightly on flowers, it is
advisable to tie a little wool round the stems of standard roses and
other things upon which they congregate. They will not crawl over the
wool. A little sulphur sprinkled over a plant will keep them from it;
while wall-fruit, etc., may be kept free from them by surrounding it
with a broad band of chalk. Should they become troublesome on account
of their numbers a strong decoction of elder leaves poured into the
nest will destroy them; or a more expeditious method of getting rid of
them is to put gunpowder in their nests and fire it with a piece of
touch-paper tied on to a long stick.

Aotus Gracillima.--A charming and graceful evergreen shrub, whose
slender branches are covered with small pea-like flowers in May. It is
most suitable for the greenhouse, and delights in a soil of loamy peat
and sand. Cuttings of half-ripened wood planted under glass will take
root. Height, 3 ft.

Aphides, or plant-lice, make their presence known by the plant
assuming an unhealthy appearance, the leaves curling up, etc.
Frequently swarms of ants (which feed upon the aphides) are found
beneath the plants attacked. Syringe the plant all over repeatedly
with gas-tar water, or with tobacco or lime-water. The lady-bird is
their natural enemy.

Apios Tuberosa (_Glycine Apios_).--An American climbing plant which
produces in the autumn bunches of purple flowers of an agreeable
odour. The foliage is light and elegant. The plant is quite hardy. It
enjoys a light soil and a good amount of sunshine. It may be increased
by separating the tubers after the tops have died down, and planting
them while they are fresh. Height, 12 ft.

Aponogeton.--_See_ "Aquatics."

Apples.--Apples delight in a moist, cool climate. All apples will not
succeed on the same soil, some preferring clay, while others grow best
in sandy loam or in well-drained peat. For a deep, good soil and a
sheltered situation the standard form grafted on the Crab-apple is
generally considered to be the most profitable. For shallow soils it
is better to graft on to the Paradise stock, as its roots do not run
down so low as the Crab. The ground, whether deep or shallow, should
receive a good mulching in the autumn; that on the deep soil being dug
in at the approach of spring, while that on the shallow soil should
be removed in the spring to allo
