SCAPE GARDENING, which, although old, contains still much of value; 
Parsons’ LANnpscAPE GARDENING and How to PLan tae Home 
Grounps, which are written on the basis of long experience in the 
parks of New York. Maynard’s LANDSCAPE GARDENING AS APPLIED 
TO Home DECORATION gives much common-sense advice.
