of the
bottom edge. Trim your paper roughly to the outline drawn. Indicate
where the holes made by the dowels pierce the paper.

4. Do the above with each zone of your mound.

5. Place these papers in proper order on dowels similarly placed
to ones in original mound at, say, 1 inch vertical interval apart.
A skeleton mound results.

6. Replace the zones of the clay mound and form the original clay
mound along the side of skeleton mound.

7. New force all the paper sheets down the dowels onto the bottom
sheet, and we have a map of clay mound with contours.

NOTE.--One-inch or 2-inch planks can be made into any desired
form by the use of dowels and similar procedure followed.

People frequently ask, "What should I see when I read a map?"
and the answer is given, "The ground as it is." This is not true
any more than it is true that the words, "The valley of the Meuse,"
bring to your mind vine-clad hills, a noble river, and green
fields where cattle graze. Nor can any picture ever put into
your thought what the Grand Canyon really is. What printed word
or painted picture can not do, a map will not. A map says to you,
"Here stands a hill," "Here is a valley," "This stream runs so,"
and gives you a good many facts in regard to them. But you do not
have to "see" anything, any more than you have to visualize Liege
in order to learn the facts of its geography. A map sets forth
cold facts in an alphabet all its own, but an easy alphabet, and
one that tells with a few curving lines more than many thousand
words could tell.

SECTION 2. SKETCHING.

Noncommissioned officers and selected privates should be able
to make simple route sketches. This is particularly useful in
patrolling as thereby a patrol leader is able to give his commander
a good idea of the country his patrol has traversed. Sketches
should be made on a certain scale, which should be indicated
on the sketch, such as 3 inches on the sketch equals 1 mile on
the ground. The north should be indicated on the sketch by means
of an arrow pointing in that direction. Any piece of paper may
be used to make the sketch on. The back of the field-message
blank is ruled and prepared for this purpose. The abbreviations
and conventional signs shown on the following pages should be
used in making such simple sketches.

The following abbreviations and signs are authorized for use on
field maps and sketches. For more elaborate map work the auth
