242 FLOWER GARDEN. 
Gravel walks, in this department, are formed precisely 
in the same manner as those in the kitchen garden. It 
may, however, be remarked, that numerous gravel walks, 
particularly when narrow, have a puny effect. All the 
principal lines should be broad enough to allow at least 
three persons to walk abreast; the others may be narrow. 
Much of the neatness of walks depends upon the material 
of which they are made. Gravel from an inland pit is to 
be preferred, though occasionally very excellent varieties 
are found upon the sea-shore. The gravel of Kensington 
and Blackheath has attained considerable celebrity ; and 
is frequently employed in remote parts of the kingdom, the 
expense being lessened by its being conveyed to different 
seaports as ballast of ships. In summer, a gravel walk 
requires hoeing and raking from time to time, to clear it 
from weeds and tufts of grass. After this operation, or 
even after a simple sweeping, it isrolled down with a hand- 
roller ; and this is repeated as often as the surface is ruffled. 
Nothing contributes more to the elegance and convenience 
of garden walks than frequent rolling. 
Edgings.—Walks are generally separated from the 
borders and parterres by some kind of dense bushy plant, 
planted closely in line. By far the best edging is afforded 
by the Dwarf Dutch Box (Buxus’ sempervirens var). It 
is extremely neat, and, when annually clipped, will remain 
in good order for many years. It may be planted at any 
season, except when in full growth or in midwinter. Ex- 
cellent edgings are also formed by Sea Pink (Statice arm- 
eria) and Double Daisy (Bellis perennis). Dwarf Gentian 
(Gentiana acaulis), London Pride (Saxifraga umbrosa), and 
the pretty native saxifrage, 8. hypnoides, are likewise used. 
Indeed, any low-growing herbaceous plant, susceptible of 
minute division, is fitted for an edging. Among the great
