ng here and there between them a small crevice in
which to plant vines, or to drop a few seeds. The top of the heap may be
left open, to allow of setting out, either in a pot or planted out in
the earth, a choice specimen plant. Among the plants the most
appropriate for the centre are: _Eulalia Japonica variegata_, and
_Zebrina_. A variegated Agave may appropriately occupy the place, or
some of the tall native wild ferns. A narrow circle may be cut around
the base of the rockery, six or eight inches wide; after this is spaded
up a row of blue Lobelia may be planted around the whole circle. Instead
of the Lobelia, a row of _Echeveria secunda glauca_, or of the
Mountain-of-Snow Geranium would look very finely. It may be well to
mention here a number of the plants most appropriate for rockeries. Who
is not familiar with the Moneywort, with its low-trailing habit and
small yellow flowers? It is peculiarly adapted for rockeries. Portulaca,
Paris Daisy (_Chrysanthemum frutescens_), _Myosotis_ (Forget-me-not),
are among the most popular plants for rockeries. The small Sedum or
Stone Crop (_Sedum acre_), is an interesting and useful little plant,
growing freely on rock or rustic work. As vines are much used for such
places, we will mention as the best hardy vines for this purpose
Veitch's _Ampelopsis_ (_A. tricuspidata_), English or Irish Ivy, and the
so-called running Myrtle. The above are entirely hardy and will stand
any amount of freezing without injury.

The following vines, although not hardy, are much used for rockeries:
Thunbergias, Tropaeolums, Kenilworth Ivy, and the German Ivy (_Senecio
scandens_). Where a rockery is formed in the midst of a pond of water,
as is often done, plants of the kind mentioned will not flourish so well
as those of a semi-aquatic nature, such as Caladiums, Callas, some
Ferns, Cannas, and Lycopodiums, all of which will flourish in moist
places.

CHAPTER XXVII.

BUDDING.

Budding as an art is simple, useful, and easily acquired by any one with
a little practice. More can be learned practically about budding in a
few hours spent with a skillful nurseryman while he is performing the
operation, than could be derived from anything we might write on the
subject. We are aware that we shall not be able to state in this brief
chapter what will be new or instructive to experienced gardeners or
nurserymen. This is not our aim, what may be old to them is likely to be
new to thousands of amate
