LANDSCAPE GARDENING. 
tained, in a single season, by planting long shoots of the osier 
willow, or any other tree which throws out roots easily from 
cuttings. 
A simple and pleasing barrier, in good keeping with cot- 
tage residences, may be formed of rustic work , as it is termed. 
For this purpose, stout rods of any of our native forest trees 
are chosen, with the bark on, six to ten feet in length ; these 
are sharpened and driven into the ground in the form of a 
lattice, or wrought into any figures of trellis that the fancy 
may suggest. When covered with luxuriant vines and 
climbing plants, such a barrier is often admirable for its 
richness and variety. 
The sunk fence, fosse, or ha-ha , is an English invention, 
used in separating that portion of the lawn near the house, 
from the part grazed by deer or cattle, and is only a ditch 
sufficiently wide and deep to render communication difficult 
on opposite sides. When the ground slopes from the house, 
such a sunk fence is invisible to a person near the latter, and 
answers the purpose of a barrier without being in the least 
obtrusive. 
In a succeeding section we shall refer to terraces with their 
parapets, which are by far the most elegant barriers for a 
highly decorated flower garden, or for the purpose of main- 
taining a proper connection between the house and the 
grounds, a subject which is scarcely at all attended to, or its 
importance even recognized as yet among us.
