At the site of Station 18, the ground was
leveled, white sand was spread, and concentric
black rings were provided by spraying with an
asphaltic emulsion. The rings were 20’ wide,
with the exception of the inner ring, which was
30’ wide. The outside diameter of the largest
ring was 440’ and the inner rings had outside
diameters of 340’, 240’, and 100’ respectively.
Station 19 requirements were similar to
Station 18, except that the diameters of the
concentric rings were smaller; the outside ring
was 310’, the two inner rings were 210’ and 100’,
respectively. It was necessary to extend the
rings over buildings that were located within
the marked area in order to provide a contin-
uousring.
