made Of the aero-photographic data in laying
out golf course. The procurement Of such
survey figures is facilitated by the fact that the
experts Of the United States Geological Survey
are making . mammoth topographic map Of the
entire land surface Of the United States Il
includes the topographic mapping Of every
square inch Of land surface every bump and

mines irrigation projects and other engineer
Ing enterprises can be planned directly from
this huge map and its ramihcatiOns without
any re-surveys IL also is the repository OF IN
valuable information for golf course architects.
JNcLE SAM provides topographic maps Of
any section Of the land area surveyed ct
small costs to either public or private agencies.
Maj Newman has secured all the topographic
data used in laying out i've golf courses from
the air from Geological Survey. with the es-
sential air pictures and mosaics at hand as SUP
plements to this typographical information.
Maj. Newman makes short work Of laying out a

architect win have to master q knowledge Of
flying and the correct Interpretation of aerial
pictures before he will be qualified to follow in
this eavalryman's tracks.
