FORMAL AND LANDSCAPE PLANTING 43 
often required to hide some unsightly object, care 
must be taken when marking out the ground that the 
eyesore is hidden from every point of view. This can 
generally be contrived by small subsidiary plantings, 
dependent on the main group. Having staked out an 
area of ground which when planted will hide the object 
from the principal point, proceed to view the site from 
all quarters, adding and remodelling as may be necessary. 
For this, and work of a similar character, the use of 
ranging poles of various heights is helpful. Supposing 
that it is desired to make a small plantation with the 
object of concealing an ugly building, the designer will 
take up his position at the principal vantage point. An 
assistant will move the poles from place to place until 
the necessary width of the plantation is determined. To 
decide the class of trees needed, and their height, which 
should not be greater than absolutely necessary, poles 
of varying heights may be raised perpendicularly, noting 
the particular one which just clears the object. Supposing 
this to be twenty-five feet, then trees twenty-five feet 
high will be required, and knowing this it remains to 
select those which are most in keeping with the surround- 
ings, or supply the special effects desired.
