Wistaria.--This noble wall plant may be abundantly produced, as a long
layer will root at every joint. It will also grow from cuttings of the
plant and root. Though of slow growth at first, when well established
it is very free-growing and perfectly hardy. It may also be grown as a
small tree for the lawn or centres of large beds by keeping the long
twining shoots pinched in.

Witch Hazel.--_See_ "Hamamelis."

Withania Origanifolia (_Pampas Lily-of-the-Valley_).--A hardy climbing
plant, attaining a height of 20 or 30 ft. in a very short period. The
foliage is small, but very dense and of a dark green, the flowers
being white. It may be raised from seed, and when once established the
roots may remain undisturbed for any length of time, merely removing
the stems as soon as they are destroyed by frost.

Wolf's Bane.--_See_ "Aconite."

Wood, to Preserve.--In order to prevent wooden posts, piles, etc.,
from rotting, dip the parts to be sunk in the earth in the following
composition:--Fine, hard sand, three hundred parts; powdered chalk,
forty parts; resin, fifty parts; linseed oil, four parts. Heat these
together in a boiler, then add red lead, one part; sulphuric acid, one
part. Mix well together, and use while hot. If too thick, more linseed
oil may be added. This composition when dry attains the consistency of
varnish, and becomes extremely hard.

Wood Lily.--_See_ "Trillium."

Woodruff.--_See_ "Asperula."

Worms, to Destroy.--To each 5 lbs. of newly-slaked lime add 15 gallons
of water. Stir it well, let it settle, draw off the clear portion, and
with it water the surface of the lawn, etc. The Worms will come to the
top and may be swept up. Worms in pots may be brought to the top by
sprinkling a little dry mustard on the surface of the soil, and then
giving the plant a good watering.

Wulfenia Carinthiaca.--A pretty and hardy perennial from the
Corinthian Alps, suitable alike for rock-work or the border, throwing
up spikes of blue flowers from May to July. During winter place it in
a frame, as it is liable to rot in the open. It needs a light, rich,
sandy soil and plenty of moisture when in growth. Cuttings will strike
in sand; it may also be propagated by seeds or division. Height, 1 ft.

state, their form and colour for several years. They are of the
