They   show   the   height   of   ground   above

or   metres   and   can   be   drawn    at   any
desired   interval.      On   the   1   inch    map,
the   contours   are   drawn   for   every   50   ft.,
while    on    the    Va,    inch    map,    they
are   drawn    for    every    200    ft.    of

The   vertical   distance   between   contour

distance   between   contours   is   called   the
Horizontal    Equivalent   (H. E.)

SCALE 1 in. = 1 MILE
To find Map reference of I
s proceed as follows —
* 1. Find Number of Grid Line West of  i  (91)
>"     Ascertain number of tenths ft   is east of (91)
This is observed to be 6.
Set it down thus, 916.   This is known as
j. EASTING
= 2. Find Number of Grid Line South of i  (94)
Ascertain number of tenths ft is North of (94)
This is observed to be 4.
Set it down thus, 944.   This is known as
NORTHING
The Map reference of ft is therefore 916944
ALWAYS MEASURE OVER TO THE EAST AND THEN
UP TO THE NORTH.   IN OTHER WORDS FIND THE
:
EASTING AND THEN THE NORTHING.
Note —When using a reference
on the Va inch map give the letter   0
of the large square concerned.
Map Reference on Va in. to mile is

Here are the four ways to set a map-
By COMPASS   Place the Compass
opened on the Magnetic North and
South Line of the Map. Turn the Map
and compass together slowly until the
Magnetic Needle of the Compass points
to Magnetic North on the Map.
By OB JECTS-When the observer
knows his position on the map and
can identify the position of some
distant object. Turn the Map so
that it corresponds with the ground.
By WATCH AND SUN —
(FOR NORTHERN HEMISPHERE)
If summer time is in effect
first set watch back on
Standard Time. Place watch n'
flat with hour hand pointing
to the SUN. True South is midway between the hour
hand and XII. True North is directly opposite. This
method is very rough.
