ADDING CHARM WITH 
ROCKWORK 
Very often the attractive use of rocks 
in the landscape marks the difference 
between that which is ordinary and 
that which is outstanding. 
In the hands of the landscape de¬ 
signer, rocks can be used with a great 
deal of charm in appropriate places. 
Perhaps your grounds call for an inter¬ 
esting rockery or a combination of pool 
and rock-garden. 
Why not let us look over your 
grounds and tell you of such possibilities.
