A STUDY of the maps sub-
mitted by scouts under
'First Class Requirement
No. 7 shows the need for some
interpretations of this test
which will make the subject
easier for both Scoutmasters
and Scouts, and which will re-
sult in a more uniform com-
pliance with the requirements.
It is hoped that this paper will
fill a long felt need.
The majority of maps sub-
mitted to date cover streets or
thickly populated areas. A
better understanding and more
efficient results will be obtained
through plotting out country
or thinly populated areas. City
sketching can often be done
from memory and the force of
the knowledge gained through
true map making is lost. Coun-
try sketching brings out all the
essentials. Special emphasis
should be laid upon principal
elevations and conventional signs.

Measurements
Judging by Eye—By practice
only can this be accurate.
Amateurs should not judge in-
tervals greater than 100 yards.
When two travel together, let
partner advance 100 paces
(measured) then hold pencil at
arm's length and measure his
apparent height oij it from
pencil—tip down—with your
thumbnail. Mark that point
with your knife. This can be
used as a distance gauge when-
ever full height is visible at
100 yards.
To Measure an Inaccessible
Height or Depth
Estimate height of object by
eye, then pace off that dis-
tance from its base, setting a
peg "A." Cut stake your own
height, marking on it the
height of the eye. Sharpen

Definitions
Map—A map is a proportionally correct
presentation of some part of the earth's
surface.
To Measure Inaccessible Distance with
Compass
Example—width of river running east
is useless unless the scale is shown

sists of placing the north point in its proper
relation to definite lines on the map, such
as railroads, wagon roads, fence lines, etc.
The north point should be placed so that Pocket Compass

Conventional Signs—Conventional signs
are certain recognized and established signs

lers or clamps, or both, to keep drawing you. Peg your second position and measure
to your first position. Distance is width of
river. If west is obstructed, walk east;

Plane table
Note book or paper tacked to a thin board
(In the absence of a plane table.)
For rough field sketching, cross section
or quadruled paper_ (10 lines to the inch)
aids greatly in noting distance.
Without a compass, a watch can be used
to plot degrees on a map. For example:—
Place XII of watch on north point shown
on map and measure degrees by consider-
ing that each minute is equivalent to six
(6) degrees.
Scale
To be determined and noted on map.
Measure distance by stride of man or
pace of horse.
Man's normal stride varies from 27" to
33" according to individuals and nature of
ground. Conventional surveyors' pace is
30".
In mapping, walk at normal stride. As-
certain number of paces to mile and num-
ber of paces to minute.
